CIGS photovoltaic cells


CIGS is mainly used in photovoltaic cells (CIGS cells), in the form of polycrystalline thin films. Unlike the silicon cells based on a homojunction, the structure of CIGS cells is a more complex heterojunction system. The best efficiency achieved as of December 2005 was 19.5%.. A team at the National Renewable Energy Laboratory achieved 19.9% new world record efficiency by modifying the CIGS surface and making it look like CIS. The 19.9% efficiency is by far the
