Thin-Film CIGS
Thin-Film CIGS


Mass-market material. Nature’s best.


Sidestepping a dependence on costly silicon, Copper Indium Gallium Selenide (CIGS) is inherently nature’s best solar-absorbing material. Leading the way for cost- and performance-efficient solar power-generation, CIGS offers a number of key benefits:


  • Thinner is better: Calling for a layer 100 times thinner than conventional silicon solar systems, CIGS material efficiencies drive down costs. In fact, a few dollars’ worth of CIGS raw ingredients can deliver the same power as a hundred dollars’ worth of silicon wafers. Manufactured with HelioVolt’s FASST™ technology, our products deliver a comparable performance to multi-crystalline silicon. They also bypass the costly assembly of cells made of silicon, and certain other thin films, into modules.


  • Best performance: CIGS is the most durable and efficient thin-film material to replace silicon for solar systems.


  • Long life: Weather-resistant and robust, with lifespan and warranties equivalent to silicon.


  • Seamless: Our thin-film CIGS can be printed directly onto a variety of construction materials, creating energy-generating building products. Think of it as one-step solar.
