Miasolé - Flexible Solar Cells
CIGS solar cells:
Copper Indium Gallium Selenide (CIGS) is a thin film solar cell used to convert sunlight into electrical energy.
This technology has a conversion efficiency of 19.2%. It sets the world record for CIGS sputtering technology. It adheres directly to surfaces and is lightweight, ultra-thin and flexible. This makes it an excellent energy source for solar-powered products such as backpacks.
