“…36,38,114,115 In a one-step spin coating process, the subtle changes in characteristics of perovskite precursor solution, involving precursor concentration, stoichiometric ratio, existence state of solute, and solvent choice enable a substantial variation in perovskite crystallization, which could determine the microstructure of a final perovskite crystal. 38,116–118 For example, the concentration-dependent grain growth of perovskite thin films was observed in the perovskite precursor solutions with different concentrations. 119 During perovskite nucleation, slightly larger nuclei tend to appear at higher precursor concentrations due to an increased system entropy Δ S .…”

“…In addition, one can see that the CsCl additive can transform the preferred orientation of the PbBr 2 film from [020] to [031], since the (020) XRD peak is more intense for the PbBr 2 film without the CsCl additive but the (031) XRD peaks are higher for those containing the CsCl additive. 32,35 After deposition of CsCl/H 2 O solution and thermal annealing, all the PbBr 2 films can be converted into perovskite films, which are mainly composed of CsPbBr 2Àx Cl 1+x , as indicated by their clear XRD peaks at B15.621, 22.041, and 38.691 (Fig. 1(c)).…”
