Abstract

This report highlights the importance of reducing the density of defect states in the absorber layer of the CZTSSe solar cells in order to reap the benefits of making a technological transition from CZTS to CZTSSe solar cells. Although, the highest power conversion efficiency (PCE) value of the simulated CZTSSe and CZTS solar cells under no defect condition is 12.3 and 7.49%, respectively, however, with increasing defect density the PCE value deteriorates to 4.12% in CZTSSe solar cell which is 1% lower than that of CZTS solar cell (5%) for the highest level of defect density.
