MANUFACTURING METHOD FOR CI(G)S BASED THIN FILM WHERE MATURING PROCESS OF SLURRY COMPRISING BINARY NANO-PARTICLES IS INTRODUCED, AND CI(G)S BASED THIN FILM MANUFACTURED BY METHOD

摘要

Provided are a manufacturing method for a CI(G)S based thin film where a maturing process of a slurry comprising binary nano-particles is introduced, and a CI(G)S based thin film manufactured by the method. The manufacturing method for a CI(G)S thin film of the present invention comprises: a step for producing CI(G)S based binary nano-particles; a step for producing a hybrid-type slurry by mixing the binary nano-particles, a solution precursor comprising CI(G)S based elements, a solvent, and a chelating agent; a step for maturing the hybrid-type slurry for five to ten days; a step for forming a CI(G)S based thin film by coating the matured hybrid-type slurry; and a step for thermally treating the formed CI(G)S thin film. Thereby, it is possible to ensure excellent reproducibility when manufacturing a CI(G)S based solar cell thin film and thus improve the reliability of the manufactured thin film.
