Ascent Solar Technologies, Inc. (ASTI) is a Colorado-based technology company that specializes in developing and manufacturing thin-film photovoltaic modules. Established in 2005 as a spin-off company from ITN Energy Systems, ASTI has managed to position itself as a leader in the green energy industry.
The headline product of Ascent Solar Technologies is the ultra-light, flexible, and powerful CIGS (Copper Indium Gallium Selenide) technology solar panels. These solar panels are far less rigid than their silicon counterparts, making them ideal for unconventional applications. Their light weight and adaptability make them perfect for use in aerospace, defense, transportation, and electronic applications, to mention a few.
ASTI distinguishes themselves from other companies in the solar industry due to their innovative approach to solar technology. They use a proprietary manufacturing process that deposits multiple layers of materials, including a thin semiconductor film, onto a flexible plastic substrate. This makes their solar panels both lightweight and durable.
ASTI's aggressive drive for innovation and expansion has led to several achievements. It was named one of Colorado’s Top Public Companies in 2010 and 2011 by ColoradoBiz Magazine. In 2012 and 2014, the company’s solar charger product line received a significant accolade when it was named one of TIME Magazine’s Top 50 Inventions.
But like any other company, ASTI has also encountered business challenges. Apart from the highly competitive solar power market, the company has had to grapple with financial difficulties and looming threats of bankruptcy. In the face of these challenges, ASTI continues to innovate and find ways to stay profitable and relevant in an ever-evolving market.
Presently, Ascent Solar Technologies is focusing on expanding their footprint in the consumer electronics industry by integrating their solar technology into various gadgets and devices to help extend their battery life. Moreover, ASTI is exploring potential high-value off-grid applications and markets where their unique lightweight module can be a differentiator.
In conclusion, Ascent Solar Technologies, Inc. is a proven innovator in the green energy industry. They've created a unique solar solution with their flexible CIGS technology and are working on ways to commercialize it further to meet the world's growing energy needs and environmental responsibilities. Despite the challenges they are currently facing, ASTI remains committed to the pursuit of progress and sustainability.

Ascent Solar Technologies is expanding its thin-film space solar testing program beyond low Earth orbit to validate its copper-indium-gallium-selenide (CIGS) PV modules for more demanding space conditions. This expansion follows NASA findings suggesting the CIGS modules can recover from radiation exposure through self-annealing properties. The company aims to confirm the "Remarkable Recovery" in environments like medium Earth orbit and geostationary orbit, potentially broadening the application of its PV products for next-generation space missions.
