Sun Shines on CIGS Photovoltaics
Feb 5, 2018 Worldwide
Copper indium gallium diselenide CIGS photovoltaics has been around for a long time even in bendable form. It is intermediate in efficiency between organic photovoltaics - poor - and gallium arsenide PV - excellent. Both of those are available in more flexible forms. Dye Sensitised Solar Cells are nearer to CIGS in efficiency but their most promising form is perovskite.
