Ascent Solar Technologies Reports Results of Atomic Oxygen Exposure Testing for Space Grade Thin-Film Photovoltaic Products Ascent Solar Technologies 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. Although silicon and gallium arsenide (GaAs) solar technologies are widely used in LEO, their long-term performance is often significantly encumbered by the highly reactive AO environment. Exposed cover glass adhesives, polymer encapsulants, interconnect coatings, and other protective materials are susceptible to erosion and degradation over time of a few percent to more than 10% over several years in LEO. This erosion contributes to power loss and reduced array lifespan. AO mitigation is a critical design consideration for ensuring reliable long-term operation. Ascent has completed several rounds of AO exposure testing, with highly favorable results for space-grade products that include 1 mil FEP film as the primary barrier and encapsulant. With exposure rates equivalent to that of six months on orbit at the altitude of the International Space Station (400km), results indicate zero loss of power. Ascent is moving forward with additional advanced AO exposure testing, simulating longer mission durations in this AO-rich environment. Announcement • Apr 28

Ascent Solar Technologies' PV Blankets to Power NOVI AI Pathfinder Spacecraft Scheduled for Launch This Spring Ascent Solar Technologies announced that its previously delivered solar blankets have been successfully integrated into NOVI's Pathfinder spacecraft, scheduled to fly on a SpaceX Falcon 9 Transporter launch no earlier than March 29th. NOVI's spring mission will demonstrate GENIE™? (Geospatial Ecosystem for Near Real-Time Information at the Edge), the company's open-access, multi-sensor, edge-compute platform designed to provide low-cost, low-latency Earth observation data and real-time geospatial intelligence. Integration of Ascent's 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 Ascent.
