Title: Efficient large guanidinium mixed perovskite solar cells with enhanced photovoltage and low energy losses

Abstract

We present a strategy for suppressing the open-circuit voltage ( V oc ) loss of perovskite solar cells by incorporating large guanidinium cations (Gua + ) into a perovskite lattice, leading to a significantly improved V oc of 1.19 V and an impressive power conversion efficiency of >21%.
