CIGS MANUFACTURING METHOD FOR CIGS THIN FILM TYPE ABSORBER LAYER MANUFACTURING METHOD FOR THIN FILM SOLAR CELL USING THEREOF AND THIN FILM SOLAR CELL

摘要

The present invention is a method for manufacturing a light absorption layer of a CIGS solar cell, in which Cu, In, Ga and Se are simultaneously evaporated using a single process method to deposit a thin film layer on a substrate n times (where n is a natural number greater than or equal to 2) The present invention relates to a method for manufacturing a CIGS light absorption layer in which a thin film layer consisting of n layers is repeatedly formed, a method for manufacturing a thin film solar cell using the CIGS thin film type light absorption layer prepared thereby, and a thin film solar cell manufactured thereby, according to the present invention In the case of manufacturing the CIGS light absorption layer through the method, a thin film layer having a bandgap slope can be manufactured through a single process method, so that a thin film having a bandgap slope can be manufactured even though the process is simple and thin.
