基于卤化物钙钛矿的图像传感器
Image Sensor Based on Halide Perovskite
摘要
Abstract
Image sensors have extensive applications in both industrial and everyday set-tings.For example,X-ray sensors are widely used in medical imaging and security screening;visible light sensors are essential in facial recognition and smart devices;near-infrared sensors are crucial for biometric identification.Currently,these image sensors mainly utilize photode-tectors based on silicon,germanium,or Ⅲ-Ⅴ group semiconductors.However,these sensors exhibit certain limitations,such as low light utilization efficiency in color image sensors and the occurrence of moiré patterns.Metal halide perovskites have emerged as a promising material for high-performance photodetectors due to their excellent optoelectronic properties,including high light absorption coefficients,tunable bandgaps,and high defect tolerance.This review summarizes the research advancements in image sensors based on metal halide perovskites,evaluates the current performance gap between these sensors and commercial devices,and suggests potential improvements to bridge this gap.关键词
