Vapour-based processing of hole-conductor-free CH3NH3PbI3 perovskite/C60 fullerene planar solar cells

Abstract
High quality CH3NH3PbI3 perovskite films deposited using a new sequential vapour deposition method enables the all-vapour fabrication of efficient, hole-conductor-free CH3NH3PbI3 perovskite/C60 fullerene solar cells.
