An approach to fabricate high-efficiency inverted planar perovskites solar cells using solution-processed organic small molecules hole transporting layer is reported. Devices using CH3NH3PbI3 as photoactive layer and PC60BM as electron transport layer show power conversion efficiencies exceeding 12% and open-circuit voltages (VOC) higher than 1 V.
