Abstract

Perovskite/silicon tandems have the potential to surpass the efficiencies possible with single-junction silicon solar cells. Recently, perovskites with wide bandgaps have been demonstrated that can reduce the thermalization losses and make it feasible to boost the efficiency. However, perovskite/silicon tandems on planar silicon cells are multi-layered devices that exhibit strong interference which makes current matching difficult to achieve in two-terminal devices. We perform comprehensive optical modeling of perovskite/silicon tandems with a range of different bandgap perovskites and textures to determine the top-cell thicknesses necessary to achieve current matching for varying top-cell bandgap. Our results show it is possible to achieve 27% efficiency with 1.67 eV bandgap perovskite, and even higher efficiency is possible by minimizing parasitic losses.
