Abstract Carrier transport behavior in perovskite light absorption layer significantly impacts the performance of perovskite solar cells (PSCs). In this work, reduced carrier recombination losses were achieved by the design of band structure in perovskite materials. An ultrathin (PbI 2 /PbBr 2 ) n film with a gradient thickness ratio was deposited as the lead halide precursor layer by thermal evaporation method, and PSCs with a gradient band structure in perovskite absorption layer were fabricated by a two-step method in ambient atmosphere. For comparison, PSCs with homogeneous perovskite materials of MAPbI 3 and MAPbI x Br 3-x were fabricated as well. It is found that the gradient type-II band structure greatly reduces the carrier lifetime and enhances the carrier separation efficiency. As a result, the PSCs with a gradient band structure exhibit an average power conversion efficiency of 17.5%, which is 1-2% higher than that of traditional PSCs. This work provides a novel method for developing high-efficient PSCs.
