CH3NH3Cl Assisted Solvent Engineering for Highly Crystallized and Large Grain Size Mixed-Composition (FAPbI3)0.85(MAPbBr3)0.15 Perovskites

High-quality mixed-cation lead mixed-halide (FAPbI3)0.85(MAPbBr3)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 comp...
