Paper Abstract

The theoretical limit photoelectric conversion efficiency of the new perovskite/silicon-based tandem solar cell can reach 42%, which has attracted wide attention due to its wide spectral response and low preparation cost. At present, the optical loss of the mechanical stack is large, so the optical design of the laminated battery is crucial. In this paper, perovskite/silicon-based laminated cells with backplate grating structure are used as models to analyze the optical absorption characteristics of stacked battery by FDTD. The results show that the parameters such as the period and height of the backplane grating structure are effective in improving absorption of long wavelength photons in bottom cells, which provides a theoretical basis for the further design of a new perovskite/silicon-based laminate battery.
