Abstract

We demonstrate effective morphology control of a CH3NH3PbI3 perovskite film with a lead(II) thiocyanate additive. The perovskite crystal size is remarkably enlarged from the nanometer to the micrometer scale with only 3% Pb(SCN)2 in solid perovskite films. Large-sized perovskite crystals enable effective enhancement of the carrier lifetime, which eventually leads to the overall improvement of the device performance of perovskite solar cells.
