Effect of Chemical and Physical Parameters on the Electrical Outputs of Cu2Zn1−yFeySnS4-Based Solar Cells by wxAMPS

Abstract

Cu2Zn1−yFeySnS4-based solar cells with different mole fractions of iron have been analyzed using numerical simulations in this study. The analysis deals with the effect of the iron content on the overall electrical performance of solar cells. Results revealed that the Voc is affected by the increase of the iron content even if it improves the other parameters. We found that the CZFTS solar cell with a mole fraction of iron equal to 1 (CFTS) showed the best results in terms of power conversion efficiency (PCE). Moreover, variations of several structural and physical parameters of the buffer CdS and the best absorber CFTS on the overall electrical characteristics of the cell were investigated. Simulations showed promising results with PCE of 20.35%, Jsc of 26.09 mA/cm2, Voc of 0.93 V, and FF of 83.93%. The results obtained can serve as a basis for the design and manufacture of high-efficiency CZFTS solar cells.
