CIGS is an acronym that stands for copper indium gallium selenide. This is a type of thin-film photovoltaic device that can be produced using a process that has the potential to reduce the cost of producing photovoltaic devices by combining a low cost of manufacturing with a high production yield. While they currently only occupy a small market share, CIGS cells have the potential to be a “disruptive” technology in the field of solar photovoltaics, as their manufacturing processes could be configured toward large-volume production.

Copper indium gallium selenide solar cells are a member of the thin film family of photovoltaic (PV) panels, shown here, and absorb light energy better than silicon PV cells.
