Researchers improve X-ray detectors using perovskite materials

A research team led by Dr. Li Yunlong at the Shenzhen Institute of Advanced Technology studied nonlinear current responses in polycrystalline metal halide perovskite X-ray detectors. Published on July 14, their findings reveal that structural imperfections affect performance. They developed a 64×64-pixel MAPbI3 detector prototype, achieving a sensitivity of 2.3×10^4 μC·Gy air^-1·cm^-2 at 0.1 V/μm, enhancing X-ray imaging quality.
