Impact of device parameters on the performance of CSC based silicon tandem solar cells

Abstract

Silicon solar cells with carrier selective contacts (CSC) provide a pathway to achieve efficiency close to the thermodynamic limit. Integrating the silicon CSC solar cell with a perovskite solar cell in a tandem structure further enhances the efficiency. In this work, we report the theoretical analysis of perovskite/silicon tandem solar cells in detail. Effect of bulk lifetimes and surface recombination velocities in silicon and perovskite absorber layers on the tandem solar cell performance has been investigated through electrical parameter evaluation.
