Metal‐free perovskites (MFPs) possess excellent photophysical properties of perovskites while avoiding the introduction of toxic metal ions and organic solvents, and have been expanded to X‐ray detection. However, iodine‐based high‐performance MFPs are tended to oxidation, corrosion, and uncontrolle...
