RISK FACTORS

An investment in our securities involves a high degree of risk. You should consider carefully all of the risks described below, together with the other information contained in this prospectus, before making a decision to invest in our securities. If any of the following events occur, our business, financial condition and operating results may be materially adversely affected. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks included here are not exhaustive or exclusive. Other sections of this prospectus may include additional factors which could adversely affect our business, results of operations and financial performance. We operate in a very competitive and rapidly changing environment. New risk factors emerge from time to time, and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

Risks Relating to Our Business

Our continuing operations will require additional capital which we may not be able to obtain on favorable terms, if at all, or without dilution to our stockholders.  Since inception, we have incurred significant losses. We expect to continue to incur net losses in the near term.

Although we have commenced production at our manufacturing facility, we do not expect that sales revenue and cash flows will be sufficient to support operations and cash requirements until we have fully implemented our new strategy of focusing on high value PV products. Product revenues did not result in positive cash flow for the 2021 year, and are not anticipated to result in a positive cash flow for the next twelve months.

During 2021 and 2020, we entered into multiple financing agreements to fund operations, raising an aggregate of $18,250,000 in net proceeds. Together with the expected proceeds from this offering of $[*] (or $[*] assuming the option to purchase additional shares is exercised in full), we believe that we have sufficient funds to continue planned operations for at least 18 months. We do not expect that sales revenue and cash flows will be sufficient to support operations and cash requirements for the foreseeable future, and we will depend on raising additional capital to maintain operations until we become profitable. There is no assurance that we will be able to raise additional capital on acceptable terms or at all. If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our existing stockholders could be significantly diluted, and these newly issued securities may have rights, preferences or privileges senior to those of existing stockholders. If we raise additional funds through debt financing, which may involve restrictive covenants, our ability to operate our business may be restricted. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, take advantage of unanticipated opportunities, develop or enhance our products, expand capacity or otherwise respond to competitive pressures could be significantly limited, and our business, results of operations and financial condition could be materially and adversely affected.

Our auditors have expressed substantial doubt about our ability to continue as a going concern.  Our auditors’ report on our December 31, 2021 consolidated financial statements expresses an opinion that our capital resources as of the date of their audit report were not sufficient to sustain operations or complete our planned activities for the year 2022 unless we raised additional funds. Additionally, as a result of the Company’s recurring losses from operations, and the need for additional financing to fund its operating and capital requirements, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises doubt as to the Company’s ability to continue as a going concern. Management cannot provide any assurances that the Company will be successful in accomplishing any of its plans. Our December 31, 2021 consolidated financial statements do not include any adjustments that might be necessary should the Company be unable to continue as a going concern.

We have a limited history of operations, have not generated significant revenue from operations and have had limited production of our products.  We have a limited operating history and have generated limited revenue from operations. In 2011 under a prior commercialization strategy plan, we had revenue of $3.5 million and a net loss of $105.7 million. Our prior commercialization strategy was initially focused on building-related PV products and later on consumer PV. Currently we are producing products in quantities necessary to meet current demand. Under our current business plan, we expect losses to continue until annual revenues and gross margins reach a high enough level to cover operating expenses. Our ability to achieve our business, commercialization and expansion objectives will depend on a number of factors, including whether:

Each of these factors is critical to our success, and accomplishing each of these tasks may take longer or cost more than expected or may never be accomplished. It also is likely that problems we cannot now anticipate will arise. If we cannot overcome these problems, our business, results of operations and financial condition could be materially and adversely affected.

We have to date incurred net losses and may be unable to generate sufficient sales in the future to become profitable.  We incurred a net loss of $6,000,003 for the year ended December 31, 2021, and net income of $1,617,444 for the year ended December 31, 2020. As of December 31, 2021, we had an accumulated deficit of $427,782,788. We expect to incur net losses in the near term. Our ability to achieve profitability depends on a number of factors, including market acceptance of our specialty PV products at competitive prices. If we are unable to raise additional capital and generate sufficient revenue to achieve profitability and positive cash flows, we may be unable to satisfy our commitments and may have to discontinue operations.

Our business is based on a new technology, and, if our PV modules or processes fail to achieve the performance and cost metrics that we expect, then we may be unable to develop demand for our PV modules and generate sufficient revenue to support our operations.  Our CIGS on flexible plastic substrate technology is a relatively new technology. Our business plan and strategies assume that we will be able to achieve certain milestones and metrics in terms of throughput, uniformity of cell efficiencies, yield, encapsulation, packaging, cost and other production parameters. We cannot assure you that our technology will prove to be commercially viable in accordance with our plan and strategies. Further, we or our strategic partners and licensees may experience operational problems with such technology after its commercial introduction

7

that could delay or defeat the ability of such technology to generate revenue or operating profits. If we are unable to achieve our targets on time and within our planned budget, then we may not be able to develop adequate demand for our PV modules, and our business, results of operations and financial condition could be materially and adversely affected.

Our failure to further refine our technology and develop and introduce improved PV products could render our PV modules uncompetitive or obsolete and reduce our net sales and market share.  Our success requires us to invest significant financial resources in research and development to keep pace with technological advances in the solar energy industry. However, research and development activities are inherently uncertain, and we could encounter practical difficulties in commercializing our research results. Our expenditures on research and development may not be sufficient to produce the desired technological advances, or they may not produce corresponding benefits. Our PV modules may be rendered obsolete by the technological advances of our competitors, which could harm our results of operations and adversely impact our net sales and market share.

Failure to expand our manufacturing capability successfully at our facilities would adversely impact our ability to sell our products into our target markets and would materially and adversely affect our business, results of operations and financial condition.  Our growth plan calls for production and operations at our facility. Successful operations will require substantial engineering and manufacturing resources and are subject to significant risks, including risks of cost overruns, delays and other risks, such as geopolitical unrest that may cause us not to be able to successfully operate in other countries. Furthermore, we may never be able to operate our production processes in high volume or at the volumes projected, make planned process and equipment improvements, attain projected manufacturing yields or desired annual capacity, obtain timely delivery of components, or hire and train the additional employees and management needed to scale our operations. Failure to meet these objectives on time and within our planned budget could materially and adversely affect our business, results of operations and financial condition.

We may be unable to manage the expansion of our operations and strategic alliances effectively.  We will need to significantly expand our operations and form beneficial strategic alliances in order to reduce manufacturing costs through economies of scale and partnerships, secure contracts of commercially material amounts with reputable customers and capture a meaningful share of our target markets. To date, we have not formed such strategic alliances and can give no assurances that we will be able to do so. To manage the expansion of our operations and alliances, we will be required to improve our operational and financial systems, oversight, procedures and controls and expand, train and manage our growing employee base. Our management team will also be required to maintain and cultivate our relationships with partners, customers, suppliers and other third parties and attract new partners, customers and suppliers. In addition, our current and planned operations, personnel, facility size and configuration, systems and internal procedures and controls, even when augmented through strategic alliances, might be inadequate or insufficient to support our future growth. If we cannot manage our growth effectively, we may be unable to take advantage of market opportunities, execute our business strategies or respond to competitive pressures, resulting in a material and adverse effect to our business, results of operations and financial condition.

We depend on a limited number of third-party suppliers for key raw materials, and their failure to perform could cause manufacturing delays and impair our ability to deliver PV modules to customers in the required quality and quantity and at a price that is profitable to us. Our failure to obtain raw materials and components that meet our quality, quantity and cost requirements in a timely manner could interrupt or impair our ability to manufacture our products or increase our manufacturing cost. Most of our key raw materials are either sole sourced or sourced by a limited number of third-party suppliers. As a result, the failure of any of our suppliers to perform could disrupt our supply chain and impair our operations. Many of our suppliers are small companies that may be unable to supply our increasing demand for raw materials as we implement our planned expansion. We may be unable to identify new suppliers in a timely manner or on commercially reasonable terms. Raw materials from new suppliers may also be less suited for our technology and yield PV modules with lower conversion efficiencies, higher failure rates and higher rates of degradation than PV modules manufactured with the raw materials from our current suppliers.

Our products may never gain sufficient market acceptance, in which case we would be unable to sell our products or achieve profitability.  Demand for our products may never develop sufficiently, and our products may never gain market acceptance, if we fail to produce products that compare favorably against competing products on the basis of cost, quality, weight, efficiency and performance. Demand for our products also will depend on our ability to develop and maintain successful relationships with key partners, including distributors, retailers, OEMs, system integrators and value-added resellers. If our products fail to gain market acceptance as quickly as we envision or at all, our business, results of operations and financial condition could be materially and adversely affected.

We are targeting emerging markets for a significant portion of our planned product sales. These markets are new and may not develop as rapidly as we expect or may not develop at all.  Our target markets include portable power, defense, transportation, space and near space markets. Although certain areas of these markets have started to develop, some of them are in their infancy. We believe these markets have significant long-term potential; however, some or all of these markets may not develop and emerge as we expect. If the markets do develop as expected, there may be other products that could provide a superior product or a comparable product at lower prices than our products. If these markets do not develop as we expect, or if competitors are better able to capitalize on these markets our revenues and product margins may be negatively affected.

Failure to consummate strategic relationships with key partners in our various target market segments, such as defense and portable power, transportation, space and near space, and the respective implementations of the right strategic partnerships to enter these various specified markets, could adversely affect our projected sales, growth and revenues.  We intend to sell thin-film PV modules for use in portable power systems, defense and portable power systems, transportation, space and near space solar panel applications. Our marketing and distribution strategy is to form strategic relationships with distributors, value added resellers and e-commerce to provide a foothold in these target markets. If we are unable to successfully establish working relationships with such market participants or if, due to cost, technical or other factors, our products prove unsuitable for use in such applications; our projected revenues and operating results could be adversely affected.

If sufficient demand for our products does not develop or takes longer to develop than we anticipate, we may be unable to grow our business, generate sufficient revenue to attain profitability or continue operations.  The solar energy industry is currently dominated by the rigid crystalline silicon based technology. The extent to which our flexible thin film PV modules will be widely adopted is uncertain. Many factors, of which several are outside of our control, may affect the viability of widespread adoption and demand for our flexible PV modules.

We face intense competition from other manufacturers of thin-film PV modules and other companies in the solar energy industry.  The solar energy and renewable energy industries are both highly competitive and continually evolving as participants strive to distinguish themselves within their markets and compete with the larger electric power industry. We believe our main sources of competition are other thin-film PV manufacturers and companies developing other solar solutions, such as solar thermal and concentrated PV technologies.

Many of our existing and potential competitors have substantially greater financial, technical, manufacturing and other resources than we do. A competitor’s greater size provides them with a competitive advantage because they often can realize economies of scale and purchase certain raw materials at lower prices. Many of our competitors also have greater brand name recognition, established distribution networks and large customer bases. In addition, many of our competitors have well-established relationships with our current and potential partners and distributors and have extensive knowledge of our target markets. As a result of their greater size, these competitors may be able to devote more resources to the research, development, promotion and sale of their products or respond more quickly to evolving industry standards and changes in market conditions than we can. Our failure to adapt to changing market conditions and to compete successfully with existing or future competitors could materially and adversely affect our business, results of operations and financial condition.

Problems with product quality or performance may cause us to incur warranty expenses, damage our market reputation and prevent us from maintaining or increasing our market share. If our products fail to perform as expected while under warranty, or if we are unable to support the warranties, sales of our products may be adversely affected or our costs may increase, and our business, results of operations and financial condition could be materially and adversely affected.

We may also be subject to warranty or product liability claims against us that are not covered by insurance or are in excess of our available insurance limits. In addition, quality issues can have various other ramifications, including delays in the recognition of revenue, loss of revenue, loss of future sales opportunities, increased costs associated with repairing or replacing products, and a negative impact on our goodwill and reputation. The possibility of future product failures could cause us to incur substantial expenses to repair or replace defective products. Furthermore, widespread product failures may damage our market reputation and reduce our market share causing sales to decline.

Currency translation risk may negatively affect our net sales, cost of equipment, cost of sales, gross margin or profitability and could result in exchange losses.  Although our reporting currency is the U.S. dollar, we may conduct business and incur costs in the local currencies of other countries in which we operate, make sales or buy equipment or materials. As a result, we are subject to currency translation risk. Our future contracts and obligations may be exposed to fluctuations in currency exchange rates, and, as a result, our capital expenditures or other costs may exceed what we have budgeted. Further, changes in exchange rates between foreign currencies and the U.S. dollar could affect our net sales and cost of sales and could result in exchange losses. We cannot accurately predict future exchange rates or the overall impact of future exchange rate fluctuations on our business, results of operations and financial condition.

A significant increase in the price of our raw materials could lead to higher overall costs of production, which would negatively affect our planned product margins, or make our products uncompetitive in the PV market.  Our raw materials include high temperature plastics and various metals. Significant increases in the costs of these raw materials may impact our ability to compete in our target markets at a price sufficient to produce a profit.

Our intellectual property rights or our means of enforcing those rights may be inadequate to protect our business, which may result in the unauthorized use of our products or reduced sales or otherwise reduce our ability to compete.  Our business and competitive position depends upon our ability to protect our intellectual property rights and proprietary technology, including any PV modules that we develop. We attempt to protect our intellectual property rights, primarily in the United States, through a combination of patent, trade secret and other intellectual property laws, as well as licensing agreements and third-party nondisclosure and assignment agreements. Because of the differences in foreign patent and other laws concerning intellectual property rights, our intellectual property rights may not receive the same degree of protection in foreign countries as they would in the United States. Our failure to obtain or maintain adequate protection of our intellectual property rights, for any reason, could have a materially adverse effect on our business, results of operations and financial condition. Some of our patents are no longer enforceable and, over time, others will expire or otherwise become unenforceable, which means a third party could practice the invention claimed, which could reduce or negatively affect our ability to compete. Further, any patents issued in connection with our efforts to develop new technology for PV modules may not be broad enough to protect all of the potential uses of our technology.

We also rely on unpatented proprietary technology. It is possible others will independently develop the same or similar technology or otherwise obtain access to our unpatented technology. To protect our trade secrets and other proprietary information, we require our employees, consultants and advisors to execute proprietary information and invention assignment agreements when they begin working for us. We cannot assure these agreements will provide meaningful protection of our trade secrets, unauthorized use, misappropriation or disclosure of trade secrets, know how or other proprietary information. Despite our efforts to protect this information, unauthorized parties may attempt to obtain and use information that we regard as proprietary. If we are unable to maintain the proprietary nature of our technologies, we could be materially adversely affected.

In addition, when others control the prosecution, maintenance and enforcement of certain important intellectual property, such as technology licensed to us, the protection and enforcement of the intellectual property rights may be outside of our control. If the entity that controls intellectual property rights that are licensed to us does not adequately protect those rights, our rights may be impaired, which may impact our ability to develop, market and commercialize our products. Further, if we breach the terms of any license agreement pursuant to which a third party licenses us intellectual property rights, our rights under that license may be affected and we may not be able to continue to use the licensed intellectual property rights, which could adversely affect our ability to develop, market and commercialize our products.

Third-party claims of intellectual property infringement may negatively impact the Company and the Company’s future financial results. The Company’s commercial success depends in part on its ability to develop, manufacture, market and sell its products and use its proprietary technology without infringing the patent rights of third parties. Numerous third-party U.S. and non-U.S. issued patents and pending applications exist in the area of the Company’s products. The Company may in the future pursue available proceedings in the U.S. and foreign patent offices to challenge the validity of patents and patent applications. In addition, or alternatively, the Company may consider whether to seek to negotiate a license of rights to technology covered by one or more of such patents and patent applications. If any patents or patent applications cover the Company’s products or technologies, the Company may not be free to manufacture or market its products as planned, absent such a license, which may not be available to the Company on commercially reasonable terms, or at all.

It is also possible that the Company has failed to identify relevant third-party patents or applications. For example, some applications may be held under government secrecy and US patent applications that will not be filed outside the United States

10

remain confidential unless and until patents issue. Moreover, it is difficult for industry participants, including the Company, to identify all third-party patent rights that may be relevant to its product candidates and technologies because patent searching is imperfect due to differences in terminology among patents, incomplete databases and the difficulty in assessing the meaning of patent claims. The Company may fail to identify relevant patents or patent applications or may identify pending patent applications of potential interest but incorrectly predict the likelihood that such patents may issue with claims of relevance to its technology. In addition, the Company may be unaware of one or more issued patents that would be infringed by the manufacture, sale or use of a current or future products, or the Company may incorrectly conclude that a third-party patent is invalid, unenforceable or not infringed by its activities. Additionally, pending patent applications that have been published can, subject to specified limitations, be later amended in a manner that could cover the Company’s technologies, its products or the use of its products.

There have been many lawsuits and other proceedings filed by third parties involving patent and other intellectual property rights, including patent infringement lawsuits, interferences, oppositions, and reexamination, post-grant review and equivalent proceedings before the USPTO and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which the Company is developing products or has existing products. As the industries the Company is involved in expand and more patents are issued, the risk increases that its product candidates may be subject to claims of infringement of the patent rights of third parties.

Parties making claims against the Company may obtain injunctive or other equitable relief, which could effectively block its ability to further develop and commercialize the Company’s products. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from the Company’s business. In the event of a successful claim of infringement against the Company, the Company may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, pay royalties, redesign its infringing products or obtain one or more licenses from third parties, which may be impossible or require substantial time and monetary expenditure.

Our future success depends on retaining our Chief Executive Officer and existing management team and hiring and assimilating new key employees, and our inability to attract or retain key personnel would materially harm our business and results of operations.  Our success depends on the continuing efforts and abilities of our executive officers, including Mr. Victor Lee, our President and Chief Executive Officer, our other executive officers, and key technical personnel. Our future success also will depend on our ability to attract and retain highly skilled employees, including management, technical and sales personnel. The loss of any of our key personnel, the inability to attract, retain or assimilate key personnel in the future, or delays in hiring required personnel could materially harm our business, results of operations and financial condition.

Our Chief Executive Officer is also employed by another company.  Our Chief Executive Officer serves as chief financial officer of another unrelated public company. This employment may compete for our Chief Executive Officer’s full attention to the Company. The Chief Executive Officer is only required to devote as much time and attention to the affairs of the Company as he deems appropriate and may engage in other business activities and/or other unrelated employment.

Our PV modules contain limited amounts of cadmium sulfide, and claims of human exposure or future regulations could have a material adverse effect on our business, results of operations and financial condition.  Our PV modules contain limited amounts of cadmium sulfide, which is regulated as a hazardous material due to the adverse health effects that may arise from human exposure and is banned in certain countries. We cannot assure you that human or environmental exposure to cadmium sulfide used in our PV modules will not occur. Any such exposure could result in third party claims against us, damage to our reputation and heightened regulatory scrutiny of our PV modules. Future regulation relating to the use of cadmium in various products could force us to seek regulatory exemptions or impact the manufacture and sale of our PV modules and could require us to incur unforeseen environmental related costs. The occurrence of future events such as these could limit our ability to sell and distribute our PV modules, and could have a material adverse effect on our business, results of operations and financial condition.

11

Environmental obligations and liabilities could have a substantial negative impact on our financial condition, cash flows and profitability.  We are subject to a variety of federal, state, local and foreign laws and regulations relating to the protection of the environment, including those governing the use, handling, generation, processing, storage, transportation and disposal of, or human exposure to, hazardous and toxic materials (such as the cadmium used in our products), the discharge of pollutants into the air and water, and occupational health and safety. We are also subject to environmental laws which allow regulatory authorities to compel, or seek reimbursement for, cleanup of environmental contamination at sites now or formerly owned or operated by us and at facilities where our waste is or has been disposed. We may incur significant costs and capital expenditures in complying with these laws and regulations. In addition, violations of, or liabilities under, environmental laws or permits may result in restrictions being imposed on our operating activities or in our being subjected to substantial fines, penalties, criminal proceedings, third party property damage or personal injury claims, cleanup costs or other costs. Also, future developments such as more aggressive enforcement policies, the implementation of new, more stringent laws and regulations, or the discovery of presently unknown environmental conditions or noncompliance may require expenditures that could have a material adverse effect on our business, results of operations and financial condition. Further, greenhouse gas emissions have increasingly become the subject of international, national, state and local attention. Although future regulations could potentially lead to an increased use of alternative energy, there can be no guarantee that such future regulations will encourage solar technology. Given our limited history of operations, it is difficult to predict future environmental expenses.

We currently anticipate having substantial international operations that will subject us to a number of risks, including potential unfavorable political, regulatory, labor and tax conditions in foreign countries.  We entered into a Long Term Supply and Joint Development Agreement (“JDA”) with TubeSolar, a related party (see “Certain Transactions—Relationship with Crowdex and TubeSolar”), and expect to expand our operations abroad in the future and, as a result, we may be subject to the legal, political, social and regulatory requirements and economic conditions of foreign jurisdictions. Risks inherent to international operations, include, but are not limited to, the following:

Our business in foreign markets will require us to respond to rapid changes in market conditions in these countries. Our overall success as an international business depends, in part, on our ability to succeed in differing legal, regulatory, economic, social and political conditions. If we are not able to develop and implement policies and strategies that are effective in each location where we will do business, then our business, results of operations and financial condition could be materially and adversely affected.

Existing regulations and policies and changes to these regulations and policies may present technical, regulatory and economic barriers to the purchase and use of PV products, which may significantly reduce demand for our PV

12

products.  The market for electricity generation products is heavily influenced by foreign, U.S., state and local government regulations and policies concerning the electric utility industry, as well as policies promulgated by electric utilities. These regulations and policies often relate to electricity pricing and technical interconnection of customer owned electricity generation. In the United States and in a number of other countries, these regulations and policies have been modified in the past and may be modified again in the future. These regulations and policies could deter end user purchases of PV products and investment in the research and development of PV technology. For example, without a mandated regulatory exception for PV systems, utility customers are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to our end users of using PV systems and make them less desirable, thereby harming our business, prospects, results of operations and financial condition. In addition, electricity generated by PV systems mostly competes with expensive peak hour electricity, rather than the less expensive average price of electricity. Modifications to the peak hour pricing policies of utilities, such as to a flat rate, would require PV systems to achieve lower prices in order to compete with the price of electricity from other sources.

We anticipate that our PV modules and their use in installations will be subject to oversight and regulation in accordance with national and local ordinances relating to building codes, safety, environmental protection, utility interconnection and metering and related matters. It is difficult to track the requirements of individual states and design equipment to comply with the varying standards. Any new government regulations or utility policies pertaining to PV modules may result in significant additional expenses to us, our business partners and their customers and, as a result, could cause a significant reduction in demand for our PV modules.

We may be subject to risks related to our information technology systems, including the risk that we may be the subject of a cyber-attack and the risk that we may be in non-compliance with applicable privacy laws.  Our operations depend, in part, on how well we and our vendors protect networks, equipment, information technology (IT) systems, and software against damage from a number of threats, including, but not limited to, cable cuts, damage to physical plants, natural disasters, intentional damage and destruction, fire, power loss, hacking, computer viruses, vandalism, theft, malware, ransomware and phishing attacks. Any of these and other events could result in IT system failures, delays, or increases in capital expenses. Our operations also depend on the timely maintenance, upgrade, and replacement of networks, equipment, and IT systems and software, as well as preemptive expenses to mitigate the risks of failures. The failure of IT systems or a component of IT systems could, depending on the nature of any such failure, adversely impact our reputation and results of operations.

We recently remediated material weaknesses in our internal control over financial reporting. If our remediation efforts were insufficient to address the material weaknesses, or if additional material weaknesses or significant deficiencies in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements, which could adversely affect our stock price and could negatively impact our results of operations.  At December 31, 2020 and March 31, 2021, we concluded that there were material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. See Management’s Discussion and Analysis—Remediation of Material Weaknesses.

While we believe that the substantial elimination of the complexities in the Company’s debt and securities accounting, along with changes in internal controls over financial reporting during the year ended December 31, 2021, have materially improved the Company’s internal control over financial reporting, and have effectively remediated the Company’s prior material weaknesses, we cannot assure that these or other measures will fully remediate, or have fully remediated, the deficiencies or material weaknesses. We cannot assure you that we have identified all of our existing significant deficiencies and material weaknesses, or that we will not in the future have additional significant deficiencies or material weaknesses. If we are unable to remediate a material weakness, or otherwise maintain effective internal control over financial reporting, we may not be able to report our financial results accurately, prevent fraud, or file our periodic reports in a timely manner.

As long as our significant stockholders, BD1, Crowdex, and TubeSolar, maintain their current holdings, the ability of our other stockholders to influence matters requiring stockholder approval will be limited.  As of March 14, 2022, BD1 beneficially owned 15,933,334 shares of our common stock, Crowdex beneficially owned 5,545,042 shares of our common stock, and TubeSolar beneficially owned 4,961,234 shares of our common stock. As of March 14, 2022, the Company had approximately 30,586,804 shares of common stock outstanding. Accordingly, BD1, Crowdex, and TubeSolar together would be able to cast approximately 86.4% of the votes entitled to vote at any meeting of stockholders of the Company (or written consent of stockholders in lieu of meeting). BD1, Crowdex, and TubeSolar, therefore, will, for the foreseeable future, have significant influence over our management and affairs, and will be able to control virtually all matters requiring stockholder

13

approval, including the election of directors and significant corporate transactions such as mergers or sales of our Company or assets. On September 15, 2021, the Company entered into the JDA with TubeSolar. See “Certain Transactions--Relationship with TubeSolar” for additional detail.

The interests of our three largest stockholders may conflict with our interests or your interests now or in the future.  Three of our stockholders, Crowdex, TubeSolar and BD1, collectively beneficially own approximately 86.4% of our Company’s common stock.

Crowdex is an investment holding company 100% indirectly beneficially owned by Bernd Förtsch. One of our directors, David Peterson, is the manager of Crowdex and a cousin of Michael J. Gilbreth, the Company’s chief financial officer.  

TubeSolar is a developer of photovoltaic thin-film tubes to enable additional application opportunities in solar power generation compared to conventional solar modules. TubeSolar is a public company headquartered in Augsburg, Germany, whose shares are listed on XETRA (primary market Dusseldorf, Germany). Bernd Förtsch directly and indirectly owns a controlling interest in TubeSolar. On September 15, 2021, the Company entered into the JDA with TubeSolar. See “Certain Transactions—Relationships with TubeSolar” for additional detail.

BD1 is an investment holding company. BD1 is 100% owned by BD Vermögensverwaltung GmbH. BD Vermögensverwaltung GmbH is 100% owned by Solar Invest International SE. Johannes Kuhn and Ute Kuhn are the beneficial owners and members of the board of directors of Solar Invest International SE. BD Vermögensverwaltung GmbH and Solar Invest International SE together own approximately 18.9% of TubeSolar’s shares.

Various conflicts of interest between us and our controlling stockholders could arise. The ownership interest and voting power of our controlling stockholders could create or appear to create potential conflicts of interest when such controlling stockholders are faced with decisions relating to us. We may not be able to resolve any potential conflicts, and even if we do, the resolution may be less favorable to us than if we were dealing with an unaffiliated third party.

So long as Crowdex, TubeSolar and BD1 continue to beneficially own a significant amount of our outstanding equity securities, those stockholders may be able to strongly influence or effectively control our decisions.

Risks Relating to our Securities and an Investment in our Securities

The price of our common stock may continue to be volatile.  Our common stock is currently traded on the OTC Markets. The trading price of our common stock from time to time has fluctuated widely and may be subject to similar volatility in the future. For example, during most of the calendar year ended December 31, 2020, our common stock traded at or below $1.00, and in 2021 our common stock ranged from $10.00 to $485.00, all prices as adjusted for the reverse stock split. The trading price of our common stock in the future may be affected by a number of factors, including events described in these Risk Factors. In recent years, broad stock market indices, in general, and smaller capitalization and PV companies, in particular, have experienced substantial price fluctuations. In a volatile market, we may experience wide fluctuations in the market price of our common stock. These fluctuations may have a negative effect on the market price of our common stock regardless of our operating performance. In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been instituted. A securities class action suit against us could result in substantial costs, potential liabilities and the diversion of management’s attention and resources and could have a material adverse effect on our financial condition.

There is currently no market for Common Warrants being sold in this offering, and a market for such warrants may not develop, which would adversely affect the liquidity and price of these warrants.  There is currently no market for the Common Warrants. Prospective stockholders therefore have no access to information about prior market history on which to base their investment decision. We plan on listing the Common Warrants, together with our common stock, on Nasdaq. Following this offering, the price of such warrants may vary significantly due to one or more factors, including general market or economic conditions. Our underwriters are not obligated to make a market in our securities, and even if they make a market, they can discontinue market making at any time without notice. Neither we nor the underwriters can provide any assurance that an active and liquid trading market in our securities will develop or, if developed, that such market will continue.

As a public company, we are subject to complex legal and accounting requirements that require us to incur substantial expenses, and our financial controls and procedures may not be sufficient to ensure timely and reliable reporting of financial information, which, as a public company, could materially harm our stock price and public

14

listing.  As a public company, we are subject to numerous legal and accounting requirements that do not apply to private companies. The cost of compliance with many of these requirements is substantial, not only in absolute terms but, more importantly, in relation to the overall scope of the operations of a small company. Failure to comply with these requirements can have numerous adverse consequences including, but not limited to, our inability to file required periodic reports on a timely basis, loss of market confidence, delisting of our securities and/or governmental or private actions against us. We cannot assure you we will be able to comply with all of these requirements or the cost of such compliance will not prove to be a substantial competitive disadvantage vis-à-vis our privately held and larger public competitors.

The Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of Sarbanes-Oxley. Our compliance with Section 404 of Sarbanes-Oxley will require we incur substantial accounting expense and expend significant management efforts. The effectiveness of our controls and procedures may, in the future, be limited by a variety of factors, including:

If we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our independent registered public accounting firm, identifies deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, we may be subject to delisting, investigations by the SEC and civil or criminal sanctions.

Our ability to successfully implement our business plan and comply with Section 404 requires us to be able to prepare timely and accurate financial statements. We expect we will need to continue to improve existing, and implement new operational, financial and accounting systems, procedures and controls to manage our business effectively.

Any delay in the implementation of, or disruption in the transition to, new or enhanced systems, procedures or controls may cause our operations to suffer, and we may be unable to conclude that our internal control over financial reporting is effective as required under Section 404 of Sarbanes-Oxley. If we are unable to complete the required Section 404 assessment as to the adequacy of our internal control over financial reporting, if we fail to maintain or implement adequate controls, our ability to obtain additional financing could be impaired. In addition, investors could lose confidence in the reliability of our internal control over financial reporting and in the accuracy of our periodic reports filed under the Securities Exchange Act of 1934, as amended (“Exchange Act”). A lack of investor confidence in the reliability and accuracy of our public reporting could cause our stock price to decline.

Once listed on Nasdaq there is no assurance that we will be able to maintain our Nasdaq listing, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions. We anticipate that our securities will be listed on Nasdaq upon consummation of this offering. There is no assurance that we will be able to maintain the listing of our shares of common stock and Common Warrants on Nasdaq. In order to list on Nasdaq, we must meet certain financial and liquidity criteria. However, we cannot assure you that our securities will continue to be listed on Nasdaq in the future.

Nasdaq requires that the trading price of its listed stocks remain above one dollar in order for the stock to remain listed. If a listed stock trades below one dollar for more than 30 consecutive trading days, then it is subject to delisting from Nasdaq. There can be no assurance that the market price of our common stock will remain at the level required for continuing compliance with Nasdaq’s minimum bid requirement. It is not uncommon for the market price of a company’s common stock to decline in the period following a reverse stock split. In any event, other factors unrelated to the number of shares of our common stock outstanding, such as negative financial or operational results, could adversely affect the market price of our common stock and jeopardize our ability to maintain compliance with Nasdaq’s minimum bid price requirement.

In addition, to maintain a listing on Nasdaq, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum

15

stockholders’ equity and certain corporate governance requirements. If we are unable to satisfy these requirements or standards, we could be subject to delisting. This would have a negative effect on the price of our common stock and would impair your ability to sell or purchase our common stock when you wish to do so. In the event of a delisting, we can provide no assurance that any action we may take to restore our compliance with the listing requirements would allow our common stock to become listed again, stabilize the market price or improve the liquidity of our common stock, prevent our common stock from dropping below the minimum bid price requirement, or prevent future non-compliance with the listing requirements.

If Nasdaq delists our securities from trading on its exchange, we could face significant material adverse consequences, including:

Our stockholders may experience significant dilution as a result of new securities that we may issue in the future.   We may issue additional common stock or securities convertible into or exchangeable or exercisable for common stock, in connection with future capital raising transactions. The issuance of material amounts of common stock by us would cause our existing stockholders to experience significant dilution in their investment in our Company. Also, if we obtain additional financing involving the issuance of equity securities or securities convertible into equity securities, our existing stockholders’ investment would be further diluted. Such dilution could cause the market price of our common stock to decline, which could impair our ability to raise additional financing.

Sales of a significant number of shares of our common stock in the public markets or significant short sales of our stock, or the perception that such sales could occur, could depress the market price of our common stock and impair our ability to raise capital.  Sales of a substantial number of shares of our common stock or other equity-related securities in the public markets could depress the market price of our common stock. If there are significant short sales of our stock, the price decline that could result from this activity may cause the share price to decline more so, which, in turn, may cause long holders of the stock to sell their shares, thereby contributing to sales of stock in the market. Such sales also may impair our ability to raise capital through the sale of additional equity securities in the future at a time and price that our management deems acceptable, if at all. In addition, a large number of our outstanding shares are not registered under the Securities Act. If and when these shares are registered or become eligible for sale to the public market, the market price of our common stock could also decline.

Some provisions of our charter documents and Delaware law may have anti-takeover effects that could discourage an acquisition of us by others, even if an acquisition would be beneficial to our stockholders, and may prevent attempts by our stockholders to replace or remove our current management.  Provisions in our Certificate of Incorporation and Bylaws, each as amended, as well as provisions of Delaware law, could make it more difficult for a third party to acquire us, or for a change in the composition of our Board of Directors (our “Board” or “Board of Directors”) or management to occur, even if doing so would benefit our stockholders. These provisions include:

16

In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless such transactions are approved by our Board. This provision could have the effect of delaying or preventing a change of control, whether or not it is desired by, or beneficial to, our stockholders.

Risks Related to this Offering

You will experience immediate and substantial dilution in the net tangible book value per share of the common stock you purchase in this offering.

Because the effective offering price per share in this offering exceeds the net tangible book value per share of our common stock outstanding prior to this offering, you will incur an immediate and substantial dilution in the net tangible book value of the shares of common stock you purchase in this offering or the shares of common stock underlying the Common Warrants you purchase in this offering. After giving effect to the sale by us of (i) 1,107,420 shares of our common stock at the assumed offering price of $9.03 per share of common stock and (ii) Common Warrants to purchase 1,107,420 shares of common stock at the assumed offering price of $9.03 per Common Warrant, and after deducting underwriting commissions and expenses, as well as other estimated offering expenses payable by us, and assuming no exercise of the Common Warrants, you will experience immediate dilution of $862 per share, representing the difference between the effective offering price per share and our as adjusted, pro forma net tangible book value per share as of December 31, 2021 after giving effect to this offering. See “Dilution”, on page 20 of this prospectus for a more detailed discussion of the dilution you will incur if you participate in this offering.

Holders of Common Warrants purchased in this offering will have no rights as common stockholders until such holders exercise their Common Warrants and acquire our common stock.

Until holders of Common Warrants acquire shares of our common stock upon exercise of such warrants, holders of Common Warrants will have no rights with respect to the shares of our common stock underlying such Common Warrants. Upon exercise of the Common Warrants, the holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

We have broad discretion in the use of the net proceeds of this offering and, despite our efforts, we may use the net proceeds in a manner that does not increase the value of your investment.

Our management will have broad discretion in the application of our existing cash and the net proceeds from this offering, including for any of the purposes described in the section titled “Use of Proceeds,” and you will not have the opportunity as part of your investment decision to assess whether such proceeds are being used appropriately. Because of the number and variability of factors that will determine our use of our existing cash and the net proceeds from this offering, their ultimate use may vary substantially from their currently intended use. Our management might not apply our existing cash and the net proceeds from this offering in ways that ultimately increase the value of your investment. The failure by our management to apply these funds effectively could harm our business. These investments may not yield a favorable return to our stockholders. If we do not invest or apply the net proceeds from this offering in ways that enhance stockholder value, we may fail to achieve expected financial results, which could cause our stock price to decline.

There can be no assurance of a market for our common stock.

We are in the process of applying to have our common stock and the Common Warrants listed on Nasdaq. To the extent approved for listing, neither we nor the underwriters can provide any assurance that an active and liquid trading market in our securities will develop or, if developed, that such market will continue. Therefore, it may be difficult to sell your shares of common stock if you desire or need to sell them. As a result, no assurances can be given that you will be able to readily sell your common stock at a price equal to or above the price you paid. The underwriters are not obligated to make a market in our securities, and even if they make a market, they can discontinue market making at any time without notice.

Moreover, the trading price of our common stock has fluctuated substantially over the past few years, and there remains a significant risk that our common stock price may continue to fluctuate substantially in the future in response to various factors, including any material developments, material variations in our periodic operating results, departures or additions of management or other key personnel, announcements of acquisitions, mergers, share consolidations, or new technology or patents, new product developments, significant litigation matters, gain or loss of significant licensees or strategic alliances,

17

significant capital transactions, substantial sales of our common stock in our trading market, and general and specific market and economic conditions.

To the extent approved for listing, as a newly listed company on Nasdaq, we will incur materially increased costs and be subject to additional regulations and requirements.

To the extend approved for listing, as a newly exchange-listed public company on Nasdaq, we would incur material additional legal, accounting and other expenses, including payment of annual exchange fees, to satisfy the continued listing standards for Nasdaq. If our common stock is listed on Nasdaq, we must meet certain financial and liquidity criteria to maintain our listing. If we fail to meet any of Nasdaq’s listing standards, our common stock may be delisted. In addition, our Board may determine that the cost of maintaining our listing on a national securities exchange outweighs the benefits of such listing. A delisting of our common stock from Nasdaq may materially impair our stockholders’ ability to buy and sell our common stock and could have an adverse effect on the market price of, and the efficiency of the trading market for, our common stock. The delisting of our common stock could significantly impair our ability to raise capital and the value of your investment.

General Risk Factors

An occurrence of an uncontrollable event such as the COVID-19 pandemic may negatively affect our operations. The novel coronavirus (“COVID-19”) pandemic in the United States and world-wide has caused business disruption which has negatively impacted and may in the future negatively impact the Company’s operations and financial results. We have seen longer lead time and higher cost in raw materials and equipment parts, increased labor cost in line with overall inflation witnessed across the country, and extended products and development cycle causing longer delivery time to our customers. We have also seen disruptions to supply chain and staff on location due to illness, like companies everywhere. Public health officials continue to recommend and mandate precautions to mitigate the spread of COVID-19, including as it relates to travel, congregating in heavily populated areas and stay-at-home orders or similar measures. While some of these measures have been lifted, there is considerable uncertainty around the duration of the pandemic in the United States and world-wide. Our entire business may be adversely impacted by actions taken to contain or treat the impact of COVID-19. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted. The impact of COVID-19 on our operations and financial results, therefore, cannot be reasonably estimated at this time.
