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.

24h Move is the share-price change in the day after each event; other market factors may also have contributed.
ASTI has mostly traded in line with news tone, with private placements drawing negative reactions and most commercial/teaming announcements seeing positive moves, though one space teaming headline triggered a sharp selloff.
Over the past months, ASTI combined capital-raising with strategic partnerships. On Nov 6, 2025, a teaming agreement with CisLunar Industries targeting U.S. space customers saw a -18.23% reaction. A later teaming deal with NovaSpark Energy on Nov 12, 2025 for defense and disaster-use power solutions drew a 2.42% gain. The current cislunar spacecraft power-testing news on Dec 3, 2025 previously coincided with an 8.18% rise. Subsequent private placement announcements on Dec 8, 2025 led to -3.11% moves, underscoring dilution sensitivity.

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.”
About Ascent Solar Technologies, Inc.
Backed by 40 years of R&D, 15 years of manufacturing experience, numerous awards, and a comprehensive IP and patent portfolio, Ascent Solar Technologies, Inc. is a leading provider of innovative, high-performance, flexible thin-film solar panels, optimized for use in space, military and defense, and other applications where mass, performance, reliability, and resilience are paramount.
Ascent’s photovoltaic (PV) modules have been deployed on space missions, multiple airborne vehicles, agrivoltaic installations, in industrial/commercial construction as well as an extensive range of consumer goods, revolutionizing the use cases and environments for solar power. Ascent Solar’s research and development center and 5-MW nameplate production facility is in Thornton, Colorado.
