Achievement of Record New Efficiency of 15.7% at Production Scale for CIGS Solar Technology

On June 9^th ASTI announced that its thin-film CIGS technology reached record efficiency at 15.7% (AM0) at production scale. This achievement aligns with the previously announced ASTI 2025 strategy which aimed to continue improving upon its thin-film PV's material quality, technological efficiency and production design optimization to increase the applicability of the technology in the space market.

Using the Titan™, a module approximately one square foot in size, ASTI can now produce a  formidable 15.7 watts in power per unit. These modules are approximately 0.03mm in thickness and just over eight grams in weight, possess an impressive power density of 1960W/kg before encapsulation.

ASTI engineering and production teams have consistently achieved increases in device efficiency and overall performance since September 2023. In the last 18 months, ASTI has reached significant milestones in efficiency testing, with the latest achievement of 15.7% representing a significant increase from Q1 2024:

• 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 continued efficiency improvements for our CIGS arrays are the direct result of our U.S.-based manufacturing team's tireless focus on process improvement and advanced device engineering," said Paul Warley, CEO of ASTI. "The jump in device efficiency we've experienced over the past two years has dramatically enhanced our technology's readiness for the space market, positioning it as an ideal solar material choice for satellite power systems and other spacecraft."

Master Services Agreement to Provide NOVI Space with Rollable PV Array Blankets for Launch in 2026

On May 27^th ASTI announced the signing of a Master Services Agreement with NOVI Space, Inc., a Virginia-based space company that develops and operates AI-powered satellites with their TRL-9 edge computing technology.

ASTI has been contracted to provide rollable PV array blankets to NOVI to deliver real-time Earth Observation insights directly from space. NOVI plans to utilize ASTI lightweight, rollable solar technology in their AI edge processing constellation, scheduled for launch in early 2026. As part of the supply agreement, NOVI will provide ASTI with solar array operational performance data from orbit. This allows ASTI to rapidly iterate and validate product enhancements for future missions and continue to build upon years of R&D and specialty engineering for products suitable to thrive in the rigors of space.

ASTI has the capabilities to deliver mission-optimized solar array solutions based on CIGS PV products already developed with spaceflight heritage. Its high-maturity CIGS PV products in manufactured in its 5MW production facility in Thornton, CO enables delivery of arrays in just 6-8 weeks, versus market competition that typically struggles to meet aggressive delivery schedules and strives for 9–12-month lead times.

Customer and Partner Discussions During Space Symposium

On April 24^th ASTI reported on its in-person tours and meetings hosted during the 40th Annual Space Symposium in Colorado Springs earlier in April 2025.

Director of Space Solutions, Julian Miller, hosted six organizations onsite at the ASTI Thornton facility, and met with several others while attending the conference. Visitors reviewed the scale of ASTI operations, met with its technical team to better understand its customization and features, and further discussed collaborations for future space programs with respect to both product development and direct sales.

The ASTI 5MW production facility currently has the capacity to ship orders in excess of 100kW this summer. Space industry discussions include the exploration of new advanced capabilities enabled by ASTI CIGS PV products' combination of resiliency with mass, volume, cost and schedule efficiencies. These opportunities span across commercial, civil and defense market sectors and include emerging markets such as in-space manufacturing, distributed space power grids and Lunar surface operations, among others.

Spaceflight-Ready PV Blankets Delivered to European Space Systems Provider in Record-Breaking Two Weeks for Launch This Year

On March 28^th ASTI announced the delivery of spaceflight-ready PV blankets to a leading European space systems provider, enabling an innovative new capability for making spacecraft lighter and more powerful. The ASTI PV blankets are expected to be flown to space later this year.

ASTI flexible CIGS PV design allows the delivered space solar array products to provide mission-enabling rollability within challenging mass and volumetric constraints. Qualification test and spaceflight operational data is expected to be made available to prospective customers as available as part of the ASTI Hardware Developer Kit program, aimed at making it easier for space mission managers and spacecraft engineers to unlock both mass savings and increased performance with Plug & Fly™ solar array hardware assemblies.

ASTI spaceflight-proven, high-TRL solar array products allow for rapid customization and short delivery timelines, thanks to its 5 MW production facility and refined manufacturing processes. This partnership enables the European space systems provider to leverage ASTI expertise, reducing both mission risk and cost.

Order Received for Advanced Space PV Module Design Revision

On March 27^th ASTI announced an order to revise the design of its space solar products after being evaluated by a potential customer interested in technologies capable of receiving beamed power.  ASTI CIGS PV products have undergone performance testing by multiple third parties evaluating technologies for receiving beamed power. An initial beamed-power optimized module was designed, prototyped, and delivered to multiple third parties for testing and evaluation in less than one month's time.
