ABSTRACT
In recent years, notable advancements have been achieved to increase the kesterite CZTSSe solar cells efficiency. The maximum experimental efficiency measured is approximately 13.6%. Compared to other (TFSCs), the current CZTSSe exhibits a low efficiency caused by a significant shortage in open-circuit voltage, and the power conversion current value is still largely lower than the Shockley-Queisser limit (28%). In this regard, this research paper presents a numerical study of CuZnTnSSe solar cell in concentrator application combined with BSF layer to improve its efficiency by using SCAPS-1D software. The solar cell is composed of ZnO/CdS/CZTSSe/Mo arrangement. Firstly, simulation and experimental published data were used for model validation. SnS layer incorporation as back surface field (BSF) results in enhancing its efficiency from 12.54% to 15.84%. Furthermore, BSF and absorber thickness and doping concentration have been optimized, resulting in an efficiency of 20.17% under ideal circumstances. The improved CZTSSe solar cell efficiency rises from 20.17% to 24.10% at 10 suns concentration when the concentrator effect is further examined. Finally, a practical test using a silicon (Si) solar cell with an 8X concentration Fresnel lens was conducted to validate the simulation approach. A similar pattern is shown under the concentration effect in both the simulation and experimental solar cells. The resultant conclusion offers insightful information about the utilization of CZTSSe solar cells in concentrators applications, especially when combined with (BSF) layer.
