摘要

Cesium-based cells have drawn plenty of attention from academics in recent years owing to their promising optoelectronic characteristics. The current study presents a comparison of the performance of ITO/WO3/CZTS/CIGS/Mg–CuCrO2/Ag-based solar cells (SCs). The doubly CIGS/CZTS -based SCs provide high performance parameters in compare to single-layered CIGS and CZTS-based SCs and limit their output. Optimising the thin film materials is one of the best strategies to achieve high efficiency, aside from physical characteristics like thickness, defect density, and series resistances. Additionally, SCAPS-1D software is used to optimise the optoelectronic parameters of J-V and QE in order to achieve high efficiency. The optimum output parameters achieved in this simulation are: JSC of 31.72 mA/cm2, VOC of 1.10 V, FF of about 85.73%, and PCE of 29.96% respectively.
