Abstract

Planar CH3NH3PbI3 perovskite solar cells with constant 17.2% average power conversion efficiency irrespective of the scan rate are described. These properties are attributed to the formation of a pure CH3 NH3 PbI3 thin film by the introduction of a HI solution. Thereby, charge-injection/separation efficiency, charge-collection efficiency, diffusion coefficient, carrier lifetime, and traps are improved.
