METHOD OF MANUFACTURING CZT(S,SE)-BASED THIN FILM FOR SOLAR CELL AND CZT(S,SE)-BASED THIN FILM MANUFACTURED THEREBY

摘要

This invention relates to a method of manufacturing a CZT(S,Se)-based thin film for a solar cell and a CZT(S,Se)-based thin film manufactured thereby. This method includes depositing Sn, Zn and Cu on a substrate in a predetermined order using evaporation method to form a CZT-based precursor thin film and subjecting the CZT-based precursor thin film to selenization or sulfurization, thereby suppressing Sn loss during the manufacturing process and increasing the energy efficiency of the solar cell using the same.
