Enhanced efficiency of perovskite solar cells through improving active layer morphology by interfacial engineering

Perovskite solar cells （pero-SCs）, with organic-inorganic hybrid perovskite semiconductors （e.g. CH3NH3PbI3） as active layer, have become the hottest research field in recent several years due to their distinguished advantages of high power conversion efficiency （15%-20%） and solutionprocessability which is very important for low cost large area production by roll-to-roll technique. To realize the high efficiency,
