Ascent Solar Expands Thin-Film Solar Testing Beyond Low Earth Orbit
Ascent Solar Technologies is set to test its CIGS thin-film solar technology in medium Earth orbit and geostationary orbit by Q4 2026. This initiative addresses rising demand for solar solutions in various space applications, including on-orbit servicing and space-based power generation.

Ascent Solar Technologies, Inc. (NASDAQ:ASTI) will conduct testing of its thin-film photovoltaic technology in medium Earth orbit and geostationary orbit, with completion anticipated in Q4 2026. This testing follows successful NASA assessments in low Earth orbit, which confirmed the technology's ability to recover from radiation exposure.
The initiative aims to qualify the technology for applications in emerging space markets, including orbital data centers and space-based solar power systems. The company's production facility in Thornton, Colorado, manufactures flexible photovoltaic solutions, applicable in various sectors, including aerospace and commercial construction. Increased demand from mission operators for reliable solar solutions may also indicate a shift in market priorities toward risk reduction and enhanced performance.
