Performance Analysis of Perovskite/CIGS Based Thin Film Solar Cell using BaSi2 as BSF Layer
The goal of this research is to analyse conversion efficiency (CE) of proposed copper indium gallium di-selenide (CIGS) thin film solar cell (TFSC) by incorporating perovskite along with CIGS. The performance enhancement is done by introducing a back surface field (BSF) and employing molybdenum (Mo) as a back contact. The possible effects on photovoltaic constraints of the perovskite/CIGS TFSC along with BSF have been examined by SCAPS-1D. The proposed (BaSi2/CIGS/Cs2AgBiBr6/TiO2/FTO/Mo/ Substrate) perovskite/CIGS thin film solar cell shows CE of 28.94 %. The parameters of thin film solar cell were varied for achieve optimized value which will lead to increase in efficiency. The optimized values of perovskite/CIGS TFSC were obtained that is CIGS thickness of 0.9 µm and BSF of 0.5 µm. In addition to this TFSC has been explored in terms of acceptor density, defect density and temperature of the device.
