CU-IN-ZN-SN-(SE,S) THIN FILM FOR SOLAR CELL AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A Cu-In-Zn-Sn-(Se,S) thin film for solar cell and a preparation method thereof are provided to cut down manufacturing costs by reducing the amount of usage of In. CONSTITUTION: In a Cu-In-Zn-Sn-(Se,S) thin film for solar cell and a preparation method thereof, the Cu-In-Zn-Sn-(Se,S) thin film for solar cell is used as a light absorption layer in a solar cell. The Cu-In-Zn-Sn-(Se,S) thin film for solar cell is a CuInZnSnS4 thin film, a CuInZnSnSe2 thin film, or a CuInZnSnS4Se2 thin film. In the Cu-In-Zn-Sn-(Se,S) thin film,(Zn+Sn) /(In+Zn+Sn) is between 0 and 0.5.
