Abstract
This paper presents an origami-inspired folded perovskite X-ray detector fabricated using printing and folding techniques. The folded architecture significantly enhances X-ray sensitivity compared to a planar design, achieving sensitivities of several hundred µC/(Gy<sub>air</sub>cm<sup>2</sup>) and a record 1409 µC/(Gy<sub>air</sub>cm<sup>2</sup>) at 150 kVp without photoconductive gain. The device also demonstrates a high spatial resolution exceeding 20 lp/mm at 150 kVp. This approach eliminates the need for photolithography, offering a potential pathway for cost-effective, high-performance X-ray detectors.
