  • Highly efficient and stable inorganic CsPbBr3

    Evaporation rate of precursor material is a critical parameter in the process of nucleation and growth for perovskite film. Here the relationship of quality for CsPbBr 3 perovskite film without annealing and evaporation rate ratio of CsBr/PbBr 2 is discussed. The evaporation rate of PbBr 2 remains unchanged at 0.5 Å s −1, and the film properties are regulated by varying the evaporation rate …
