Much less additive content of 0.5% CaI2 instead of 5% PbI2 was incorporated into the CH3NH3PbI3 film and a dense and surface-smooth morphology was obtained with much enlarged crystal grains. The champion PSC based on MAPbI3(CaI2)0.005 layer demonstrated a very high PCE of 19.3% with superior long-term stability.
