THORNTON, Colo., June 09, 2025 (GLOBE NEWSWIRE) — Ascent Solar Technologies, Inc. (Nasdaq: ASTI), a leading U.S. innovator in the design and manufacture of lightweight, flexible, and durable CIGS thin-film photovoltaic (PV) solutions, has announced that its thin-film CIGS technology has achieved a record efficiency of 15.7% (AM0) at production scale. This milestone aligns with the Company’s previously announced strategy for 2025, which focuses on enhancing the material quality, technological efficiency, and production design optimization of its thin-film PV technology to make it more applicable in the space market.

Utilizing the Titan™, a module approximately one square foot in size, Ascent can now generate an impressive 15.7 watts of power per unit. These modules are about 0.03mm thick and weigh just over eight grams, boasting a remarkable power density of 1960W/kg before encapsulation. Since September 2023, Ascent’s engineering and production teams have consistently improved device efficiency and overall performance. In the past 18 months, the company has reached significant milestones in efficiency testing, with the latest achievement of 15.7% marking a substantial increase from previous quarters:

– Q3 2023: 11.6 watts
– Q4 2023: 13.3 watts
– Q1 2024: 14.0 watts
– Q2 2025: 15.7 watts

(Note: Power generation figures reflect STC conditions and AM0.)

“These ongoing efficiency improvements for our CIGS arrays stem from our U.S.-based manufacturing team’s dedicated focus on process enhancements and advanced device engineering,” stated Paul Warley, CEO of Ascent Solar Technologies. “The significant increase in device efficiency over the past two years has greatly enhanced our technology’s readiness for the space market, making it an ideal solar material for satellite power systems and other spacecraft.”
