| Popis: | Manipulation of perovskite crystallinity in order to obtain the desired optoelectronic properties is a critical issue. Perovskite structural characterization has been carried out applying several tools, which usually interrogate bulky portions of the material, averaging out over the inhomogeneities at the sub-micron scale [1]. Preliminary results obtained through photoluminescence microscopy across the crystal grains [2] showed that a clear understanding of the entangled relationship between structural and physical properties of perovskites is still missing. Ultrafast transient absorption (TA) experiments on macroscopic CH 3 NH 3 PbI 3 films previously demonstrated that the mesoscale film morphology impacts on the electron-hole interactions [3]. In small crystals ( |
