摘要：
Disclosed herein is a method of manufacturing CIGS-based thin-film solar cell, including the steps of: forming molybdenum electrode on Na-free substrate (S1); forming Na supply sources on parts of the surface of the molybdenum electrode (S2); forming CIGS-based precursor thin film on the molybdenum electrode (S3); and heat-treating the CIGS-based precursor thin film with selenium to diffuse Na from the Na supply sources into the CIGS-based precursor thin film, thus forming CIGS-based thin film (S4). The method is advantageous in that the random diffusion of Na can be prevented due to using Na-free substrate, and that Na is supplied into CIGS-based thin film serving as a light-absorbing layer of a solar cell by additional Na supply sources, thus improving the efficiency of a solar cell.
