Evaluating the Resistance of Bifacial Perovskite Photodetectors to Xenon Ion Irradiation (Adv. Sci. 9/2026)

Bifacial Perovskite Photodetectors In their Research Article (DOI: 10.1002/advs.202516418), Askhat N. Jumabekov and co-workers present bifacial perovskite photodetectors exhibiting remarkable radiation tolerance under xenon ion irradiation (1.75 MeV/nucleon, 231 MeV) with fluences up to 1011 nucleons cm−2. A comprehensive analysis of the photodetector characteristics reveals that, even after intense irradiation, the devices retain over 60% of their initial performance, highlighting their strong resilience, structural stability, and suitability for reliable operation in harsh radiation environments.
