  • 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 ...

    Both the histories of evaporation rates show cycling following that of heating. The evaporation rate increased rapidly during ON-phase and then declined sharply during the OFF-phase. For high moisture content samples, the maximum evaporation rate increased constantly with the drying time due to increased temperature and reduced during OFF-phase.
