In this work, large‐sized CH 3 NH 3 PbBr 3 single crystals were successful grown using solution evaporation method with hydrohalic acid and N, N‐Dimethylformamide (DMF) as solvent respectively. The lattice parameters of cubic CH 3 NH 3 PbBr 3 were estimated using XRD method. The solubility of CH 3 NH 3 PbBr 3 in hydrobromic acid was determined at the temperature range between 20 °C–90 °C. A special micro‐solution crystallizer was designed to in‐situ study the morphology of CH 3 NH 3 PbBr 3 crystal. The largest crystal face was indexed by the XRD patterns and it would be {110} for CH 3 NH 3 PbBr 3 grown from HBr solution and {100} from DMF solution. The results show that solvent would affect the morphology and crystal habit greatly during crystal growth from solution.
