Abstract

(Graph Presented) High-performance planar-heterojunction (PHJ) solar cells based on large band-gap (1.70-1.83 eV) perovskites are demonstrated. By incorporating Cl- into the MAPb(I1-Y BrY)3, the crystallinity and homogeneity of the solution-processed perovskite thin films are much improved, which results in an increased charge carrier diffusion length from ≈160 nm to ≈700-800 nm. This enhancement leads to a high power conversion efficiency (PCE) of 10% in the low-temperature solution-processed PHJ devices.
