　　We report a doping method to enhance the performance of solution processed planar heterojunction perovskite solar cells.By doping a small percentage(3 wt%)of polyethylenimine(PEI)as additive into the PCBM electron transport layer of an inverted perovskite solar cell,which led to significant enhancements of power conversion efficiency from(5.9±0.2)%to(10.4±0.2)%.
