a Crystal domain size estimated by the radial peak width (FWHM) as a function of reaction time and the domain size growth of iodide perovskite is quite rapid and the resolution limit is reached within seconds. b Table summarizing preferred orientation and angular distribution, and preferred orientation of c MAPbI3 and d MAPbBr3 grains with respect to the plane of the substrate. The preferred orientation of perovskite crystallites during the real-time experiment was determined by investigating the angular intensity distribution for the respective Bragg reflections.
