SCAPS Modeling of CMTS Solar Cell with ZrS₂ Buffer Layer

Abstract

The aim of this work is to study the photovoltaic performance of CMTS-based solar cell using solar cell capacitance simulator-1D. The use of ZrS2 as a buffer layer for CMTS-based solar cell is the novelty of this work. The impact of several parameters such as thickness, defect density, electron affinity, and doping concentration on the cell performances is investigated to improve cell performance. It is observed that these parameters impact significantly the solar cell performance. The optimized solar cell obtained an efficiency of 31.54% with an open-circuit voltage of 0.99 V, short-circuit current density of 36.44 mA/cm 2 , and fill factor of 87.69%. The results suggest guidelines for developing low-cost and highly efficient CMTS thin-film solar cells.
