摘要：

We report the addition of a small amount of Pb(SCN)(2) into PbI2 in a two-step solution method. The resulting CH3NH3PbI3-x(SCN)(x) perovskite films present larger-sized crystals and fewer traps than CH3NH3PbI3. Their planar solar cells exhibit a maximum power conversion efficiency of 11.07% with remarkably high reproducibility and good stability.
