Numerical simulation of CZTS solar cell with silicon back surface field

Formation of back surface field has an important impact on the solar cell performances. In this work, a numerical simulation of CdS/CZTS based solar cell is performed using the solar cell capacitance Simulator (SCAPS). The simulation was run in order to study the effect of silicon back surface field (BSF) layer in the rear side. The thickness and carrier density impact on the performances of the cell were predicted. From the simulation results, the cell with BSF layer exhibited better characteristics and an improving in conversion efficiency from 7.72 % to 10.69% has been reached. (C) 2018 Elsevier Ltd.
