METHOD FOR PRODUCING A light absorption layer thin film solar cells COPPER-INDIA-gallium-sulfur-selenium

摘要

A kind of copper indium gallium sulphur selenium film offer preparing solar cell light absorption layer. This method uses antivacuum liquid phase chemical process, includes the following steps: to form source solution, includes copper, indium, gallium, sulphur and selenium; Using solution to form precursor film antivacuum liquid phase process in substrate; Dry and annealing precursor film. Therefore, resulting composite membrane copper indium gallium sulphur selenium is.
