Folded Perovskite X-ray Detector with High Sensitivity and High Spatial Resolution (conference Presentation)

High performance X-ray detectors can be realized by a variety of different approaches. However, more and more attention is paid to direct conversion X-ray detectors in a planar device geometry that use hybrid organic-inorganic perovskite semiconductors as absorber material. This study follows an alternative approach and uses a folded instead of a planar device architecture in order to realize a high performance X-ray detector. By reporting on the fabrication of a foldable perovskite sensor array and by demonstrating a high X-ray sensitivity and a high spatial resolution when the array is folded, we prove the concept of the folded perovskite detector design.
