In this publication, a perovskite–silicon tandem solar cell with periodic nanotextures and an optically advanced rear reflector with a dielectric buffer layer is presented. The optimization of the design is performed with JCMsuite. Experiments could demonstrate a certified power conversion efficiency of 29.80%.
