Abstract: Improving the stability of lead iodide (PbI2), especially photostability, is in crucial demand for the realization of application‐level optoelectronic devices. In this regard, deposition of organic polymers on PbI2 as a protective layer is a common strategy to improve its stability, but polymers with low thermal conductivity generally cannot produce the desired effect. Herein, a novel strategy is proposed for improving the photostability of PbI2 at different excitation wavelengths, including 320, 405, and 532 …
