Perovskite-Silicon Thin Film Based Tandem Solar Cell

Abstract

A perovskite-microcrystalline silicon-based thin-film tandem solar cell was designed and investigated, where perovskite and microcrystalline cells used as top and bottom cells, respectively, for better and higher light absorption utilizing the very high open-circuit voltage. The study was carried out for simulation results of quantum efficiency and short circuit current based on different thicknesses of the top and bottom cell-intrinsic layer. A very good short circuit matched current has been obtained at around 10.56 mA/cm² leading to a maximum 23.30% solar cell conversion efficiency. A Finite Difference Time Domain mathematical method has been employed to investigate, where the Maxwell Curl’s equations have been rigorously used with the help of MATLAB.
