Abstract

By performing spatially resolved Raman and photoluminescence spectroscopy with different illumination conditions, we have achieved a unified understanding towards the spectroscopy signatures of the organic-inorganic hybrid perovskite, transforming from the pristine state (CH₃NH₃PbI₃ or MAPbI₃) to fully degraded state (i.e., PbI₂), for samples with varying crystalline domain size from mesoscopic scale to macroscopic size, synthesized by three different techniques.
