Persistent PbI₂-Passivated Microdomains in As-Prepared MAPbI₃ Perovskite Thin Film Revealed by Spatially Resolved Photoluminescence and Raman Maps

Methylammonium lead iodide (MAPbI₃) perovskite has been widely studied for its optoelectronic properties, but its polycrystalline thin films inevitably contain grain boundaries and defects that degrade performance and stability. PbI₂ is often considered a destabilizing agent in...
