Performance enhancement of an eco-friendly CsSnI-based perovskite solar cell using numerical simulation.

The significant limitations of stability and toxicity pose a substantial barrier to the practical application of lead-based perovskite solar cells. In the pursuit of environmentally sustainable and lead-free materials for the development of high-performance perovskite solar cells, this investigation assesses the theoretical feasibility of , a tin-based inorganic perovskite, as a potential cornerstone for commercially successful perovskite solar cell technology. An investigation into charge transport materials and their thicknesses, absorber properties and defect densities, metal contacts, operating temperature, and both series and shunt resistances led to the realization of novel, to our knowledge, //// configuration through the solar cell capacitance simulator in one-dimension (SCAPS-1D). This configuration achieved a power conversion efficiency of 30.22%, an open-circuit voltage of 1.75 V, short-circuit current density of 32.75/, and a fill factor of 85.77%. The obtained results are expected to improve the performance of eco-friendly, lead-free inorganic solar cells by utilizing Sn-based perovskite as an absorbing layer.
