FABRICATION METHOD FOR THIN FILM SOLAR CELL WITH KESTERITE ABSORBER
摘要
A method of fabricating a thin film solar cell includes the following steps. A molybdenum (Mo)-coated substrate is provided. Absorber layer constituent components, two of which are sulfur (S) and selenium (Se), are deposited on the Mo-coated substrate. The S and Se are deposited on the Mo-coated substrate using thermal evaporation in a vapor chamber. Controlled amounts of the S and Se are introduced into the vapor chamber to regulate a ratio of the S and Se provided for deposition. The constituent components are annealed to form an absorber layer on the Mo-coated substrate. A buffer layer is formed on the absorber layer. A transparent conductive electrode is formed on the buffer layer.
