Defects found on the surfaces of organic-inorganic perovskite films are detrimental to the device efficiency, reproducibility and stability. Herein, 2-hydrozybenzophenone (HBP) is introduced to the perovskite/spiro-OMeTAD interface in which the optimized device shows superior power conversion effici...
