source mass. (d) Grain size correlation graph of the deposited perovskite films according to the source mass. The inset shows a predicted controllable range of the grain size and thickness of the MAPbI3 films by the empirical fit shown as the dashed line.

(a) A graph of thickness of the flash evaporated perovskite film as a function of the amount of the MAPbI3 single crystal power source. (b) Cross-sectional SEM images for a single- and multi-step deposited perovskite films by flash evaporation for comparison. (c) Top-view SEM images for showing grain size variation for deposition with different
