Abstract
A method of manufacturing a CIGS-based solar cell including a transparent rear electrode, the method comprising forming a rear electrode layer including a transparent oxide material; forming rear electrode patterns including a metal material on the rear electrode layer; forming a CIGS-based light absorption layer on the rear electrode layer on which the rear electrode patterns are formed; forming a buffer layer on the light absorption layer; and forming a front electrode including a transparent material on the buffer layer, wherein the rear electrode patterns are provided with a transmissive portion, through which light is transmitted, formed between patterns of the metal material.
