Investigation of Sulfurization Time Duration Process Effects on Thermally Evaporated CZTS Absorber Layer for Photovoltaic Application

In this study, Cu2ZnSnS4 (CZTS) thin films were deposited onto Mo coated soda lime glass (SLG) substrates using thermal evaporation deposition method. Stoichiometric CZTS powder (99.95%) is used as the source material. All the deposited samples were then sulfurized at different time from 10 minutes to 50 minutes at 580°C. The characteristics of the sulphurized films were investigated. Overall, the result showed a potential CZTS’s existence although several secondary phases also being detected.
