Abstract
Copper-zinc-tin-sulfide (CZTS) solar cells are increasingly attracting researchers due to their low cost, non-radioactive behavior, and environmental friendliness. A SCAPS simulation study of these solar cells with zinc oxide (ZnO)/cadmium sulfide (CdS) core-shell nanowires and different thicknesses of absorber, buffer, and window is described in this study. The study resulted in an optimized model with a CZTS absorber, a CdS buffer, and a ZnO window with respective thicknesses of 830 nm, 90 nm, and 140 nm, efficiency (EFF) of 16.62%, a factor of fill (FF) of 81.75%, open circuit voltage (Voc) of 0.61 V and short circuit current density (Jsc) of 6.3 cmA/cm 2 . These results are very close to those reported in the literature. Keywords: CZTS; Efficiency; shell thickness; ZnO/CdS core-shell nanowires; SCAPS.
