Ascent Solar Technologies, Inc. engages in the design, development, and manufacture of solar technology and power solutions for remote locations and extreme environments. The company is headquartered in Thornton, Colorado and currently employs 16 full-time employees. The company went IPO on 2006-07-11. Its technology provides renewable power solutions to production and specialty solar markets where traditional rigid solar panels are not suitable, including aerospace, agrivoltaics, and niche manufacturing/construction sectors. The company designs and develops finished products to design and develop integrated solutions for products, such as satellites, spacecraft, airships, and fixed wing unmanned aerial vehicles (UAVs). The company is also engaged in developing its zinc oxysulfide process. The firm manufactures its products by affixing a thin Copper-Indium-Gallium-diSelenide (CIGS) layer to a plastic substrate using a large format, roll-to-roll process that permits it to fabricate its PV modules in an integrated sequential operation. The company uses monolithic integration techniques, which enable it to form complete PV modules with back-end assembly of inter-cell connections.
