摘要

We report the addition of a small amount of Pb(SCN)₂ into PbI₂ in a two-step solution method. The resulting CH₃NH₃PbI_3-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.
