Ascent Solar Technologies, Inc.

Business Overview

Ascent Solar Technologies, Inc. (“Ascent” or the "Company") is a solar technology company that manufactures and sells photovoltaic ("PV") solar modules that are flexible, durable, and possess attractive power to weight and power to area performance. Our technology provides renewable power solutions to high-value production and specialty solar markets where traditional rigid solar panels are not suitable, including space power beaming, aerospace, satellites, near earth orbiting vehicles, fixed wing unmanned aerial vehicles (“UAV”), aquatic, terrestrial, and other weight-sensitive markets (including DoD drone and space operations) with transformational high quality, value added product applications. We operate in these target markets because they have highly specialized needs for power generation and offer attractive pricing due to the significant technological requirements.

We believe the value proposition of Ascent’s proprietary solar technology not only aligns with the needs of customers in our target markets, but also overcomes many of the obstacle’s other solar technologies face in space, aerospace and other markets. Ascent designs and develops finished products for end users in these areas and collaborates with strategic partners to design and develop integrated solutions for products like satellites, spacecraft, airships and UAV. Ascent sees significant overlap in the needs of end users across some of these markets and believes it can achieve economies of scale in sourcing, development, and production in commercializing products for these customers.

The integration of Ascent's solar modules into space, near space, and aeronautic vehicles with ultra-lightweight and flexible solar modules is an important market opportunity for the Company. Customers in this market have historically required a high level of durability, high voltage and conversion efficiency from solar module suppliers, and we believe our products are well suited to compete in this premium market and will fill a void in the satellite market with a lower cost, lighter module and a product that, if struck by an object in space, will create limited space debris.

Product Update

The Company continues to focus on cell and aerial efficiency improvements on our Copper-Indium-Gallium-diSelenide ("CIGS")-based solar cells. The Company continues to improve overall performance and efficiencies by minimizing optical losses and improving overall short-circuit current and open-circuit voltages. These efforts resulted in Ascent’s engineering and production teams consistently achieving increases in device efficiency and overall performance since September 2023, with its latest achievement at 15.7%. The Company continues to focus its R&D efforts on increasing aerial efficiencies and power to weight ratios in the AM0 spectrum.

Due to the high durability enabled by the monolithic integration employed by our technology, the capability to customize modules into different form factors and what we believe is the industry leading light weight and flexibility provided by our modules, we believe that the potential applications for our products are extensive, including integrated solutions anywhere that may need power generation such as power beaming solutions, or vehicles in space or in flight.

Commercialization and Manufacturing Strategy

We manufacture our products by affixing a thin CIGS layer to a flexible, plastic substrate using a large format, roll-to-roll process that permits us to fabricate our flexible PV modules in an integrated sequential operation. We use proprietary monolithic integration techniques which enable us to form complete PV modules with little to no costly back-end assembly of inter-cell connections. Traditional PV manufacturers assemble PV modules by bonding or soldering discrete PV cells together. This manufacturing step typically increases manufacturing costs and, at times, proves detrimental to the overall yield and reliability of the finished product. By reducing or eliminating this added step, using our proprietary monolithic integration techniques, we believe we can achieve cost savings in, and increase the reliability of, our PV modules.

Advantages of CIGS on a Flexible Plastic Substrate

Thin film PV solutions differ based on the type of semiconductor material chosen to act as a sunlight absorbing layer, and also on the type of substrate on which the sunlight absorbing layer is affixed. To the best of our knowledge, we believe we are the only company in the world currently focused on commercial scale production of PV modules using CIGS on a flexible, plastic substrate with monolithic integration. We utilize CIGS as a semiconductor material because, at the laboratory level, it has a higher demonstrated cell conversion efficiency than amorphous silicon (“a-Si”) and cadmium telluride (“CdTe”). We also believe CIGS offers other compelling advantages over both a-Si and CdTe, including:

•

CIGS versus a-Si: Although a-Si, like CIGS, can be deposited on a flexible substrate, its conversion efficiency, which already is generally much lower than that of CIGS, measurably degrades when it is exposed to ultraviolet light, including natural sunlight. To mitigate such degradation, manufacturers of a-Si solar cells are required to implement measures that add cost and complexity to their manufacturing processes.

•

CIGS versus CdTe: Although CdTe modules have achieved conversion efficiencies that are generally comparable to CIGS in production, we believe CdTe has never been successfully applied to a flexible substrate on a commercial scale. We believe the use of CdTe on a rigid, transparent substrate, such as glass, is unsuitable for a number of our applications. We also believe CIGS can achieve higher conversion efficiencies than CdTe in production.

We also believe that, although over time, Gallium Arsenide ("GaSa") modules have achieved conversion efficiencies that are generally comparable to CIGS, GaSa is more expensive than our CIGS products and that CIGS has a more advantageous weight per watt output when compared to GaSa.

We believe our choice of substrate material further differentiates us from other thin-film PV manufacturers. We believe the use of a flexible, lightweight, insulating substrate that is easier to install provides clear advantages for our target markets, especially where rigid substrates are unsuitable. We also believe our use of a flexible, plastic substrate provides us significant cost advantages because it enables us to employ monolithic integration techniques on larger components, which we believe are unavailable to manufacturers who use flexible, metal substrates. Accordingly, we are able to significantly reduce part count, thereby reducing the need for costly back end assembly of inter cell connections. As the only company, to our knowledge, focused on the commercial production of PV modules using CIGS on a flexible, plastic substrate with monolithic integration, we believe we have the opportunity to address the aerospace and other weight-sensitive markets with transformational high quality, value added product applications. It is these same unique features and our overall manufacturing process that enable us to produce extremely robust, light and flexible products.

Competitive Strengths

We believe we possess a number of competitive strengths that provide us with an advantage over our competitors.

•

We are a pioneer in CIGS technology with a proprietary, flexible, lightweight, high power PV thin film product that positions us to penetrate a wide range of attractive high value added markets such as aerospace, power beaming, and agrivoltaics. In addition, we have provided renewable power solutions for off grid, portable power, transportation, defense, and other markets. By applying CIGS to a flexible plastic substrate, we have developed a PV module that is efficient, lightweight and flexible; with the highest power-to-weight ratio in at-scale commercially available solar. Relative to our thin film competitors, we believe our advantage in thin film CIGS on plastic technology provides us with a superior product offering for these strategic market segments.

•

We have the ability to manufacture PV modules for different markets and for customized applications without altering our production processes. Our ability to produce PV modules in customized shapes and sizes, or in a variety of shapes and sizes simultaneously, without interrupting production flow, provides us with flexibility in addressing target markets and product applications, and allows us to respond quickly to changing market conditions. Many of our competitors are limited by their technology and/or their manufacturing processes to a more restricted set of product opportunities.

•

Our integrated, roll-to-roll manufacturing process and proprietary monolithic integration techniques provide us a potential cost advantage over our competitors. Historically, manufacturers have formed PV modules by manufacturing individual solar cells and then interconnecting them. Our large format, roll-to-roll manufacturing process allows for integrated continuous production. In addition, our proprietary monolithic integration techniques allow us to utilize laser patterning to create interconnects, thereby creating PV modules at the same time we create PV cells. In so doing, we are able to reduce or eliminate an entire back end processing step, saving time as well as labor and manufacturing costs relative to our competitors.

•

Our lightweight, powerful, and durable solar panels provide a performance advantage over our competitors. For applications where a premium is placed on the weight and profile of the product, our ability to integrate our PV modules into portable packages offers the customer a lightweight and durable solution.

•

Our proven research and development capabilities position us to continue the development of next generation PV modules and technologies. Our ability to produce CIGS based PV modules on a flexible plastic substrate is the result of a concerted research and development effort that began more than 20 years ago. We continue to pursue research and development in an effort to drive efficiency improvements in our current PV modules and to work toward next generation technologies and additional applications.

•

Our manufacturing process can be differentiated into two distinct functions; a front-end module manufacturing process and a back-end packaging process. Our ability to produce finished unpackaged rolls of CIGS material for shipment worldwide to customers for encapsulation and integration into various products enhances our ability to work with partners internationally and domestically.

Competition

We believe our thin film, monolithically integrated CIGS technology enables us to deliver sleek, lightweight, rugged, high performance solutions to serve these markets as competitors from other thin film and c-Si companies emerge. The landscape of thin film manufacturers encompasses a broad mix of technology platforms at various stages of development and consists of a number of medium and small companies.

The market for traditional, grid connected PV products is dominated by large manufacturers of c-Si technology, although thin film technology on glass has begun to emerge among the major players. We anticipate that while these large manufacturers may continue to dominate the market with their silicon-based products, thin film manufacturers will likely capture an increasingly larger share of the market.

We believe that our modules offer unique advantages. Their flexibility, low areal density (mass per unit area), and high specific power (power per unit mass) enable use on weight-sensitive applications, such as portable power, conformal aircraft surfaces, high altitude long endurance (HALE) fixed wing and lighter than air (LTA) vehicles, and space applications that are unsuitable for glass-based modules. Innovative product design, customer focused development, and our rapid prototyping capability yield modules that could be integrated into virtually any product to create a source of renewable energy. Whether compared to glass based or other flexible modules, our products offer competitive advantages making them unique in comparison to competing products.

Research and Development and Intellectual Property

Our technology was initially developed at ITN beginning in 1994. In early 2006, ITN assigned to us certain CIGS PV-specific technologies, and granted to us a perpetual, exclusive, royalty free, worldwide license to use these technologies in connection with the manufacture, development, marketing and commercialization of CIGS PV to produce solar power. In addition, certain of ITN’s existing and future proprietary process and control technologies, although nonspecific to CIGS PV, were assigned to us. ITN retained the right to conduct research and development activities in connection with PV materials, and we agreed to grant a license back to ITN for improvements to the licensed technologies and intellectual property outside of the CIGS PV field.

We intend to continue to invest in research and development in order to provide near term improvements to our manufacturing process (including to reduce costs) and products (including improve technology to increase power), as well as to identify next generation technologies relevant to both our existing and potential new markets. During the years ended December 31, 2025 and 2024, we incurred approximately $2,443,194 and $2,300,948, respectively, in research, development and manufacturing operations costs, which include research and development incurred in customizing products for customers, as well as manufacturing costs incurred while developing our product lines and manufacturing process. We also plan to continue to take advantage of research and development contracts to fund a portion of this development.

We protect our intellectual property through a combination of trade secrets and patent protections and own several patents that protect our manufacturing process.

Suppliers

We rely on several unaffiliated companies to supply certain raw materials used during the fabrication of our PV modules and PV integrated electronics. We acquire these materials on a purchase order basis and do not have long term purchase quantity commitments with the suppliers, although we may enter into such contracts in the future. We currently acquire all of our high temperature plastic from one supplier, although alternative suppliers of similar materials exist. We purchase component molybdenum, copper, indium, gallium, selenium and indium tin oxides from a variety of suppliers. We also continue the process of identifying and negotiating arrangements with alternative suppliers of materials in the United States and Asia.

The manufacturing equipment and tools used in our production process have been purchased from various suppliers in Europe, the United States and Asia. Although we have had good relations with our existing equipment and tools suppliers, we monitor and explore opportunities for developing alternative sources to drive our manufacturing costs down.

Employees

As of December 31, 2025, we had 14 full-time and 4 part-time employees.

Company History

We were formed in October 2005 from the separation by ITN of its Advanced Photovoltaic Division and all of that division’s key personnel and core technologies. ITN, a private company incorporated in 1994, is an incubator dedicated to the development of thin film, PV, battery, fuel cell and nanotechnologies. Through its work on research and development contracts for private and government entities, ITN developed proprietary processing and manufacturing know-how applicable to PV products generally, and to CIGS PV products in particular. Our Company was established by ITN to commercialize its investment in CIGS PV technologies. In January 2006, ITN assigned to us all its CIGS PV technologies and trade secrets and granted to us a perpetual, exclusive, royalty free worldwide license to use certain of ITN’s proprietary process, control and design technologies in the production of CIGS PV modules. Upon receipt of the necessary government approvals in January 2007, ITN assigned government funded research and development contracts to us and also transferred the key personnel working on the contracts to us.
