Abstract
Kesterite are chalcogenide materials which is popular for its inexpensive, environment friendly and whose elements are abundantly available. However, its efficiency is less than 12% as it processes high recombination rate. To boost the efficiency of CZTSe kesterite solar cell use of tunable bandgap material CZTSSe as back surface field layer (BSF) prevent the material from these problems. In this analysis, the novel configuration: Mo/CZTSSe/CZTSe/CdS/ZnO/AZO influence of varying compositions S and Se and their parameters are analyzed. The Efficiency, J sc and V oc of the optimized solar cell is investigated to be 33.83%, 56.29(mA/cm2) and 0.689(V) respectively.
