Ascent Solar announced positive results from its preliminary atomic oxygen exposure testing for its space-grade thin-film photovoltaic products. In tests simulating six months of exposure at the altitude of the International Space Station, the company's thin-film products demonstrated zero loss of power. Ascent plans to proceed with additional advanced exposure testing simulating longer mission durations in Low-Earth Orbit. "These positive results represent yet another critical value proposition of our PV technology, enabling spacecraft operators to endure the punishing conditions of space," said Paul Warley, CEO of Ascent Solar.

About ASTI
Ascent Solar Technologies, Inc. is a solar technology company that manufactures and sells photovoltaic (PV) solar modules. 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. It 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). It is also engaged in developing its zinc oxysulfide process. The Company 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. It uses monolithic integration techniques, which enable it to form complete PV modules with back-end assembly of inter-cell connections.
