solar panel 9x4-blue-1

We manufacture flexible thin-film solar solutions that bring reliable electric power to use cases where mass, shape & survivability matter.

Ascent solar films are developed using proprietary CIGS manufacturing processes

We bring together 40 years of R&D, 15 years of manufacturing, numerous awards and extensive patent protection to cement our leadership in the photovoltaics market.

Our thin film PV panels are manufactured using cutting-edge CIGS (Copper-Indium-Gallium-Selenide) with patented monolithic integration.

Our patent-protected processes enable us to precisely apply layers of these elements on a thin (25micron) polyamide substrate to create resilient and featherweight panels that convert sunlight into electric power.

Ascent Solar is the only manufacturer commercially producing CIGS solar on a plastic substrate with monolithic integration, a key differentiator that reinforces Ascent Solar's leadership in the solar industry.
