Ascent Solar Technologies Provides Leading Space Company with Thin-Film PV modules for Spacecraft Power Generation Testing in Cislunar Space

Rhea-AI Summary

Ascent Solar Technologies (ASTI) announced on December 3, 2025 that it provided test modules of its featherweight, flexible thin-film photovoltaic (PV) technology to a leading space company for spacecraft power generation testing in Cislunar space (between Earth and the moon).

Preliminary test results are described as promising for the modules' ability to generate power in deeper-space radiation environments. The company said its refined manufacturing supports rapid delivery and that arrays aim to add capability without significant mass penalty for lunar and beyond-moon missions.

THORNTON, Colo., Dec. 03, 2025 (GLOBE NEWSWIRE) -- Ascent Solar Technologies (“Ascent”), the leading U.S. innovator in the design and manufacturing of featherweight, flexible thin-film photovoltaic (PV) solutions, today announced that it recently provided test modules of its thin-film PV technology to a leading space company.

The modules are currently being tested on their ability to generate power for spacecraft in Cislunar space, the region of space between the Earth and the moon. Preliminary findings from these tests have shown promising results for the technology’s capabilities.

Reaching the moon requires significantly more energy than achieving low Earth orbit for space vehicles. Ascent’s solar power generation products are being evaluated in trade studies like these and others to help maximize space vehicle mission capabilities without adding mass that could weigh vehicles down.

“Equipping a spacecraft with Ascent’s thin-film solar arrays that can endure the extreme radiation found in deep space enables mission designs that can go farther, accomplish more, and operate longer on the lunar surface and beyond,” said Paul Warley, CEO of Ascent Solar Technologies. “Our manufacturing processes have been continuously refined for over a decade, allowing us to meet rapid delivery deadlines for customers looking to make swift decisions. We’re meeting the customer’s needs with a high-efficiency, durable technology that is ready to be delivered right when they need it.”
