In this work, numerical modelling and simulation of CZTGS thin film solar cells have been carried out using the Solar Cell Capacitance Simulator (SCAPS-1D). A device structure of AZO/CdS/CZTGS/Mo was modelled using this one-dimensional simulation program. The baseline model of the device gave an efficiency   9.39 %, a fill factor FF  63.61 %, an open circuit voltage Voc  0.86 V, and a short circuit current Jsc  17.39 mA/cm2. The optimization process includes the variation of the absorber layer thickness, doping concentration, and device operating temperature. The optimal values of these parameters include an absorber layer thickness of 2.0 m, a doping concentration of 1  1016 cm – 3 at a thickness of 2.0 m, and an operating temperature of 310 K with a back contact material work function of 5.0 eV. These values will provide essential information and guidelines for the development of a highly efficient and pro-mising CZTGS photovoltaics.
