CHALCOGENIDE SEMICONDUCTOR THIN FILM AND FABRICATION METHOD THEREOF

摘要

PURPOSE: A chalcogenide semiconductor thin film and a manufacturing method thereof are provided to produce high quality solar cell absorption layers in large quantities by performing a safe manufacturing process and using non-toxic materials. CONSTITUTION: A precursor powder is mixed with hydrazine monohydrate or an alcohol solvent. The powder and the mixture of the solvent are coated on a substrate. A crystallized thin film is formed by thermally processing the coated mixture. The particle size of the precursor powder is less than 300nm. The mixture is thermally processed in the range of from 400 to 500°C.
