摘要：
X-ray detection technology has been widely used in medical diagnosis，security detection and scientific research. The direct X-ray detector has higher theoretical detection efficiency，space and energy resolution，and has been widely concerned at home and abroad. Perovskite is an ideal material for direct X-ray detectors because of its large attenuation coefficient，high bulk resistivity，suitable optical band gap and easy large area fabrication. With the increasing demand for detection performance，reasonable device structure design is particularly important. This review introduces the research progress of perovskite direct X-ray detectors from two perspectives：electrode engineering and energy band engineering. Finally，we summarize the research progress and present our views on its future development. We hope this review will provide reference and inspiration for researchers. © 2024 Chines Academy of Sciences. All rights reserved.
