Abstract

Lead-halide hybrid perovskites are recently emerging as promising materials for high energy radiation detection thanks to the combination of high absorption coefficient, excellent transport properties, even in polycrystalline films, and their solution processability. Here we present flexible perovskite X-ray detectors based on solution deposited thin films. A triple cation perovskite is deposited on a thin plastic foil reaching no more than 3 μm in total thickness. Thanks to its small thickness, the detector can be adapted to very complex surfaces. The photodetector showed a clear and box-like response to 150 kVp X-ray with a sensitivity of (6.30 ± 0.02) μCGy−1cm−2 when operated in passive mode.
