Modeling of Perovskite/Si Tandem Solar Cell

Based on a drift-diffusion simulator, the modeling of perovskite/Si tandem solar cell with tunnel junction is presented in this work. Current matching is explored between the two sub-cells. It is predicted that such a tandem cell can achieve conversion efficiency as high as 28.27% with open-circuit voltage and short-circuit current density as 2.04 V and 16.18 mA/cm2, respectively. As approaches for cell design optimization, the results are also analyzed versus the thickness and the minority carrier recombination lifetime of the perovskite layer.
