Abstract

We improve the performance of blade-coated perovskite/silicon tandem solar cells using two approaches. First, we introduce F6TCNNQ as a molecular dopant in the precursor ink to enable micrometer-thick perovskite films, compatible with textured silicon bottom cells. Second, we minimize the energy mismatch between the hole selective contact and perovskite, resulting in a champion tandem efficiency of 29.7%.
