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 of manufacturing a light absorbing layer of a CIGS solar cell, the step of depositing a thin film layer on a substrate by simultaneously evaporating Cu, In, Ga, and Se using a single process method (where n is a natural number of 2 or more) A method of manufacturing a CIGS light absorbing layer formed of a thin film layer composed of n layers repeatedly, a method of manufacturing a thin film solar cell using the CIGS thin film type light absorbing layer prepared thereby, and a thin film solar cell manufactured thereby, according to the present invention When the CIGS light absorbing layer is manufactured through a method, a thin film layer having a bandgap gradient can be manufactured through a single process method, so that the process is simple and a thin film having a bandgap gradient can be produced even at a thin thickness.
