“…CdS thin films can be prepared by different techniques [4][5][6][7][8][9][10][11] such as thermal evaporation, close spaced sublimation, metal organic chemical vapor deposition (MOCVD), molecular-beam epitaxy (MBE), chemical bath deposition (CBD), chemical spray pyrolysis (CSP), electrodeposition and sputtering. Among these methods, thermal evaporation is one of the suitable methods for depositing large area thin film for solar cell application [12].…”
