Abstract

Abstract : In article number1707001, Min‐Seok Jang, Hyungjun Kim, and co‐workers propose gold‐based halide perovskites as a lead‐free and stable material for very‐thin‐film perovskite solar cells (PSCs). Using a multiscale simulation, this already‐existing material is found to have ideal optical properties for PSCs. This work is expected to inspire work toward the realization of this new concept in PSCs based on mixed‐valence perovskites.
