Abstract
Hybrid organic-inorganic perovskite semiconductors represent a promising class of materials for direct conversion X-ray detectors. Due to their processability at low temperatures, perovskite thin films offer the ease of scalable solution-based processing on mechanically flexible substrates, enabling novel device concepts such as lightweight, robust, curved, and folded detectors. In this study, we use digital inkjet printing to realize triple cation perovskite X-ray detectors on mechanically flexible substrates and evaluate the detector performance by the X-ray sensitivity, the dark current, and the X-ray stability. Our results prove the concept of mechanically flexible inkjet-printed triple cation perovskite X-ray detectors for the realization of novel detector designs.
