Ascent Solar Technologies, Inc. (Nasdaq: ASTI) is backed by 40 years of R&D, 15 years of manufacturing experience, numerous awards, and a comprehensive IP and patent portfolio. ASTI is a leading provider of innovative, high-performance, flexible thin-film solar panels for use in environments where mass, performance, reliability and resilience matter. ASTI 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. The ASTI research and development center and 5-MW nameplate production facility is strategically located in Thornton, Colorado.
Thin-Film Space Solar Products Experience Zero Damage in Atomic Oxygen Exposure Test Campaign
On June 29th ASTI announced the results of its preliminary Atomic Oxygen (AO) exposure testing for its space grade thin-film PV products. Testing has shown significant resilience to Atomic Oxygen in Low-Earth Orbit (LEO).
AO is a highly reactive and energetic particle that is the most predominant in LEO. Interaction with AO causes damage to many materials in the form of shrinking, cracking, erosion and oxidation. Specialty coatings and chemical treatments are often the most effective approach to enhancing the resilience of space faring polymers, metal surfaces and composites.
In LEO, AO often degrades solar arrays by eroding the polymers used in blanket construction, which hampers their flexibility and exposes their electrical components to damage, and oxidizing metallic interconnects. AO can directly interact with compounds that cover the solar cells, causing oxidation that reduces their transmission of light to the photoactive portion of the cell, ultimately yielding less power over time.
“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 ASTI. “With best-in-class lightweight panels, a highly flexible and rollable form factor, as well as resilience to the stresses of launch, our PV continues to prove itself to be the best choice for orbital power systems, especially as the commercial space market continues its rapid orbital infrastructure expansion in the coming years.”
PV Blankets Power NOVI AI Pathfinder Spacecraft Scheduled for Spring Launch
On February 25th ASTI announced that its previously delivered solar blankets have been successfully integrated into the NOVI Pathfinder spacecraft, scheduled to fly on a SpaceX Falcon 9 Transporter.
The ASTI flagship open-access, multi-sensor, edge-compute platform is designed to provide low-cost, low-latency Earth observation data and real-time geospatial intelligence.
Integration of the ASTI flexible CIGS array allows for a tightly rolled configuration that minimizes the stowed volume. Pathfinder, the toaster-sized hyperspectral imaging spacecraft will generate 150W, an amount of power typically seen on larger spacecraft at higher costs. NOVI is poised to recognize compounded savings across its planned constellation by partnership with ASTI.
ASTI Spurs Development of CIGS PV Modules Capable of Generating Multiple Times More Power for Space Beaming
On February 5th ASTI announced its plans to continue development of distributed power receiving products in 2026 to account for growing demand for space-based energy beaming technologies.
These ASTI development efforts include both internally funded research and development as well as continued work with the NASA Marshall Spaceflight Center and Glenn Research Center, which is on schedule to successfully conclude this spring. ASTI plans to present the results of these development programs at select space industry conferences to be announced later this year.
These solar module technology advancements are uniquely enabled by ASTI in-house manufacturing capabilities at its 5-MW production facility in Thornton, Colorado. The facility allows for ASTI commercial-off-the-shelf CIGS PV products to be further optimized in order to be able to receive both sunlight in addition to more distributed power from a number of transmission sources and providers such as Star Catcher Industries.
ASTI further plans for continued technology progression through partnerships like that with Cislunar Industries that stand to effectively enable spacecraft to generate and utilize multiple times more power with a solar array of any given size.
