description: "Ascent Solar Technologies reported zero power loss in preliminary atomic oxygen exposure tests for its space-grade thin-film photovoltaic products. The testing simulated six months in low-Earth orbit at 400 km altitude using a 1 mil FEP film barrier. These results support the company's durability claims against polymer erosion and interconnect oxidation, which are critical for long-term array performance. Additional testing to simulate longer mission durations is planned."

# Ascent Solar says thin-film space solar products show zero power loss in atomic oxygen test

-   Ascent Solar Technologies reported zero power loss in preliminary atomic oxygen exposure tests for its space-grade thin-film photovoltaic products. \* Testing simulated six months in low-Earth orbit at International Space Station altitude of 400 km, using 1 mil FEP film as barrier. \* Results support durability claims in an environment that can erode polymers and oxidize interconnects, a key driver of long-term array performance. \* Additional atomic oxygen testing is planned to simulate longer mission durations in low-Earth orbit.
