Abstract:
1. A method for fabricating a three-component CuInS 2 thin film comprising: (1) fabricating a copper thin film by depositing an asymmetric copper precursor selected from the group consisting of copper ethylbutyrylacetate of Formula 1 and copper ethylisobutyrylacetate of Formula 2 on a substrate by metal-organic chemical vapor deposition (MOCVD); and (2) fabricating a CuInS wherein the deposition of the indium-sulfur-containing precursor in the step (2) is carried out a substrate temperature of 350° C. to 430° C., the composition ratio of copper, indium and sulfur components contained in the CuInS
