    • Disclosed is a method for manufacturing a CI(G)S thin film as a light absorbing layer of a solar cell. The method includes the steps of: preparing a substrate; manufacturing a CI(G)S-based compound which is a precursor; forming a CI(G)S-based precursor thin film by coating the substrate with the precursor CI(G)S-based compound; drying the CI(G)S-based precursor thin film formed on the substrate; selenizing the dried CI(G)S-based precursor thin film through heat treatment to form a CI(G)S thin film; dipping the formed CI(G)S thin film in a solution containing sodium (Na) to deposit a buffer layer; and heat treating the CI(G)S thin film on which the buffer layer is deposited so that the Na on the buffer layer can be moved to the CI(G)S thin film in a Na+ state, thereby reducing defects of crystal grains of the CI(G)S thin film by the Na+ and using the CI(G)S thin film having improved performance as a light absorbing layer of a solar cell.
