摘要：
Hybrid organic-inorganic perovskite solar cells (PSCs) have exhibited huge potential for commercial application due to their various advantages such as high performance, flexible and so on. The inorganic hole conductor-based inverted planar PSCs are particularly significant on account of low cost and high stability. Here, we have successfully improved the power conversion efficiency (PCE) of this type of PSCs to 19.0% with CuOx as hole conductor and hybrid CH3NH3PbI3-xClx perovskite as light absorber prepared by a novel Cl doping process based on a modified one-step fast deposition-crystallization method. This novel Cl doping process has proven to be a crucially effective procedure for enhancing the device performance due to the remarkable morphology and hole mobility improvement of the perovskite film, conspicuous intrinsic defects reduction in the film and prominent increase of the device recombination resistance.
