摘要：

High-quality mixed-cation lead mixed-halide (FAPbI(3))(0.85)(MAPbBr(3))(0.15) perovskite films have been prepared using CH3NH3Cl additives via the solvent engineering method. The UV/Vis result shows that the addition of additives leads to enhanced absorptions. XRD and SEM characterizations suggest that compact, pinhole-free and uniform films can be obtained. This is attributable to the crystallization improvement caused by the CH3NH3Cl additives. The power conversion efficiency (PCE) of the F-doped SnO2 (FTO)/compact-TiO2/perovskite/Spiro-OMeTAD/Ag device increases from 15.3% to 16.8% with the help of CH3NH3Cl additive.
