In the present work, a thin film solar cell (TFSC) structure (ITO/Al-ZnO/i-ZnO/ZnS/CIGS/CZTS/CZTSSe/Au/Substrate) based on CIGS/CZTS absorber layer has been proposed. It aims to be cost-effective non-toxic material. The proposed structure mainly emphasizes on the effect of CIGS/CZTS double absorber layer with CZTSSe as back surface field (BSF) layer along with phosphorescent, non-toxic, and wide band gap ZnS as buffer layer. SCAPS 1-D has been utilized for device modeling and to evaluate the electrical properties of the photovoltaic parameters. The performance enhancement is done by comparing different BSF and buffer layers, thus evaluating the potential of the CIGS/CZTS absorber layer of a TFSC. For this proposed structure, the thickness of both absorber layer has been optimized (varied from 0.8 to 1.5 µm) as well as BSF layer thickness has been optimized (varied from 0.3 to 1.0 µm). Proposed TFSC achieves maximum power conversion efficiency (PCE) of 28.28%, fill factor (FF) of 87.22%, open-circuit voltage (VOC) of 0.935 V and short-circuit current density (JSC) of 34.68 mA/cm2for the optimized CIGS/CZTS thickness of 1.5 µm/1.5 µm and BSF layer thickness of 0.3 µm. With the help of the proposed structure, cost- and toxicity-related problems have been resolved, which may lead to the production of highly efficient TFSC.
