Investigation on the Relative Influence of Absorber Layer Defect States Over Performance of Pb-Based and Sn-Based Perovskite Solar Cells

Abstract

Currently, the research in third-generation solar cells is proliferating in an exponential manner. Among these, the Perovskite solar cell has been the preferred research matter among the researchers. This study consists of numerical simulation-based comparison between various standard parameters of the lead-free perovskite solar cell and tin-based (lead-based) perovskite solar cell using SCAPS-1D. The comparison is performed based on performance parameters viz. open-circuit voltage, short circuit current density, fill factor and efficiency. We observed that despite the presence of severe order of defect states the performance of tin-based perovskite solar cell was superior which could be critical from the perspective of lead-free perovskite solar cell manufacturing and commercialization.
