摘要：
Immersing organometal halide perovskite crystals in CH3NH3I solution converts PbI2 impurities to CH3NH3PbI3 perovskite, yielding excellent carrier transport. Hence, the power conversion efficiency of perovskite solar cells is improved from 17.7% to 19.3% based on increased light absorption and decreased series resistance.
