Disclosed is a method of manufacturing a CI(G)S-based thin film, in which a slurry prepared by mixing two or more kinds of binary nanoparticles containing CI(G)S-based elements, a solution precursor containing a CI(G)S-based element, an alcoholic solvent and a chelating agent is used to reduce the carbon layer formed between the CI(G)S-based thin film and molybdenum, and which includes (a) mixing two or more kinds of binary nanoparticles containing CI(G)S-based elements, a solution precursor containing a CI(G)S-based element, an alcoholic solvent and a chelating agent, thus preparing a slurry; (b) subjecting the slurry to non-vacuum coating, thus forming a CI(G)S-based thin film; and (c) subjecting the CI(G)S-based thin film to selenization heat treatment. |
