ASCENT SOLAR TECHNOLOGY: Flexible CIGS Thin-Film Solar for Space, Aerospace & Agrivoltaics

Who We Are: A Leading U.S. Thin-Film Solar Manufacturer

Ascent Solar Technology, Inc. is an American thin-film photovoltaic manufacturer and innovator headquartered in Thornton, Colorado. Listed on the Nasdaq Stock Market under the ticker symbol ASTI, Ascent Solar occupies a unique niche in the global solar industry: designing and producing flexible, ultra-lightweight CIGS solar panels built for applications where traditional rigid silicon panels fail due to weight, rigidity, or operating environment constraints.

Unlike commodity solar manufacturers targeting residential rooftops, Ascent Solar has deliberately focused on high-value specialty markets—space and defense, aerospace and unmanned aerial vehicles (UAVs), and agrivoltaics—where the company’s patented technology creates a decisive competitive advantage. This strategic focus has earned Ascent Solar partnerships with organizations including NASA, SpaceX, and a growing roster of UAV and agricultural solar customers worldwide.

Company History & Leadership

Ascent Solar was founded in 2005 as a spinout focused on commercializing CIGS thin-film solar technology for niche, high-performance applications. Over two decades, the company has built an extensive patent portfolio, scaled its proprietary roll-to-roll manufacturing capability, and grown its customer base across the aerospace, defense, and clean-energy sectors.

A significant milestone in the company’s global footprint was its acquisition of Flisom AG, the Swiss flexible solar firm, which expanded Ascent’s intellectual property and European market access. The company is currently led by CEO Paul Warley, who has steered the organization toward commercialization at scale in its three core end markets.

Our Mission & Vision

Ascent Solar’s mission is to revolutionize solar energy use cases that conventional technology cannot address. Where rigid silicon panels are too heavy, too fragile, or simply the wrong shape, Ascent’s flexible, durable, and high-performance photovoltaic solutions open entirely new categories of solar deployment.

“Ascent Solar engineers flexible photovoltaics for the environments where conventional rigid panels simply cannot go — orbit, altitude, and the farm field alike.”

The Core Technology: Advanced CIGS Thin-Film Photovoltaics

At the heart of every Ascent Solar product is CIGS — Copper-Indium-Gallium-Selenide — a semiconductor compound that forms an extraordinarily efficient light-absorbing layer when deposited as a thin film. Unlike crystalline silicon, which requires thick, rigid wafers, CIGS can be deposited in layers mere microns thick onto a flexible substrate, enabling an entirely new class of photovoltaic module that is simultaneously lightweight, flexible, and high-performing.

What Makes Ascent Solar Unique?

Ascent Solar’s technological differentiation rests on three interlocking pillars: its proprietary CIGS chemistry, its use of a lightweight polyamide substrate (as thin as 25 microns), and its patented monolithic integration process.

Monolithic integration is the manufacturing method by which Ascent creates individual photovoltaic circuits on a single, continuous substrate without manual cell-tabbing and stringing. Laser scribing defines each cell boundary directly on the deposited CIGS layer, yielding a seamless, integrated module with no solder joints or mechanical connections that could fail under flex or vibration. This process is patent-protected and central to Ascent’s ability to produce reliable, high-performance flexible modules at scale.

TECHNOLOGY COMPARISON

Ascent Solar CIGS Thin-Film	Traditional Rigid Silicon Panels
✓ Ultra-lightweight (grams per watt)	✗ Heavy glass-and-aluminum construction
✓ Mechanically flexible — bends and curves	✗ Rigid — cannot flex or conform
✓ Monolithic integration — no solder joints	✗ Solder-tabbed cells — failure-prone joints
✓ Radiation-resilient for space environments	✗ Susceptible to radiation degradation
✓ Deployable on curved or irregular surfaces	✗ Flat surfaces only
✓ Roll-to-roll manufacturing at scale	✗ Batch manufacturing, limited scalability
✓ Patent-protected process IP	✗ Commodity technology, no key IP
✓ Survives vibration and thermal cycling	✗ Breaks under flexion or severe vibration

Manufacturing Excellence: Roll-to-Roll Production

Ascent Solar’s roll-to-roll manufacturing process is adapted from the printing and packaging industries and optimized for thin-film solar production. A continuous web of polyamide substrate is fed through a series of deposition chambers where the CIGS absorber layer, transparent conductive oxide, and other functional layers are deposited in sequence.

This process enables production of long, continuous sheets of flexible solar film — something impossible with rigid silicon wafer technology. With more than 15 years of manufacturing experience, Ascent Solar has refined this process to achieve consistent, high-quality outputs that meet the rigorous specifications of aerospace and space customers.

Transforming Industries: Key Applications

Ascent Solar’s flexible CIGS technology is not a solution looking for a problem — it was engineered for specific, demanding applications where conventional solar panels are unsuitable. The company has identified three primary end markets where its technology creates differentiated, defensible value.

Space & Defense

Space & Defense

Spacecraft, satellites, and space vehicles demand power sources that are lightweight enough to justify launch cost, flexible enough to fold into constrained payload volumes, and durable enough to survive the brutal radiation and thermal cycling of the space environment. Ascent Solar’s CIGS thin-film panels meet all three requirements. The company’s technology has been validated through NASA testing, confirming performance and reliability in space radiation environments. A flagship partnership with NOVI saw Ascent Solar panels integrated into a spacecraft that launched aboard a SpaceX vehicle — among the most demanding and visible validations in the commercial space sector.

3.2 Aerospace & Unmanned Aerial Vehicles (UAVs)

✈️  Aerospace & UAVs

Unmanned Aerial Vehicles (UAVs) and drones face a fundamental constraint: battery energy density limits flight endurance. Integrating solar power directly into aircraft surfaces is an elegant solution — but only if the solar panels add negligible weight and can conform to aerodynamic wing profiles. Ascent Solar’s flexible, lightweight CIGS panels are purpose-built for this challenge. The most compelling case study is the Silent Falcon UAV, a solar-electric unmanned aircraft whose integration of Ascent Solar panels achieved a 50% extension in operational range — a performance improvement of profound strategic significance for defense and commercial surveillance applications.

Agrivoltaics (AgPV)

Agrivoltaics (AgPV)

Agrivoltaics — the co-location of solar energy generation and agricultural production on the same land — is one of the fastest-growing segments in the global renewable energy sector. Traditional rigid solar panels can be deployed in agrivoltaic configurations, but their weight and rigidity create challenges for specific applications such as vertical solar tubes and greenhouse cladding. Ascent Solar’s flexible CIGS film integrates directly into agrivoltaic infrastructure in ways rigid panels cannot. The partnership with Tube Solar AG sees Ascent Solar film wrapped around agricultural tubes deployed in field settings, generating clean energy while simultaneously supporting crop cultivation — a genuinely novel configuration enabled entirely by the film’s flexibility and durability.

FUTURE TECHNOLOGY Perovskite Solar: Ascent at the Frontier of Next-Generation PV Beyond CIGS, Ascent Solar has been involved in research and development related to perovskite solar cell technology — widely regarded as the most promising next-generation photovoltaic material. Perovskite cells have demonstrated exceptional efficiency gains in laboratory settings, and their compatibility with thin-film deposition processes makes them a natural evolution pathway for manufacturers like Ascent with deep thin-film manufacturing expertise. As perovskite technology matures toward commercial deployment, Ascent Solar’s manufacturing capabilities and IP position it to play a meaningful role in the next chapter of advanced solar development.
