Abstract
Perovskites have attracted extensive attention as radiation detection material due to their long carrier diffusion length and lifetime,high absorption coefficient,and flexible manufacturing process.Com-pared with polycrystalline structures,single crystal perovskites improve the performance of optoelectronic devices due to their low defect state density,better photoelectric characteristics,and chemical stability.Herein,we review the recent progress of single crystal perovskite X-ray detectors.First,we briefly intro-duced the basic concepts,detection mechanisms,figure of merits of perovskite X-ray detectors,and the preparation methods of single crystal perovskites.Then,we summarized the significant advancements in single crystal perovskite X-ray detectors in recent times.Finally,we discussed the critical challenges and some practicable solutions for developing high-performance X-ray detectors.
