Abstract：
Halide perovskites have shown great potential in X-ray detection due to outstanding optoelectronic properties. However, finding a cost-effective and environmentally sustainable method for handling end-of-life devices has remained challenging. Here, a \"One-Click Restart\" eco-friendly recycling strategy is introduced for end-of-life perovskite X-ray detectors. This method, utilizing water, allows for the recapture and reuse of both perovskite and conductor materials. The process is straightforward and environmentally friendly, eliminating the need for further chemical treatment, purification, additional additives or catalysts, and complex equipment. A sustainable device cycle is developed by reconstructing flexible perovskite membranes for wearable electronics from recycled materials. Large-scale, flexible membranes made from metal-free perovskite DABCO-N2H5-I3 (DABCO = N-N\'-diazabicyclo[2.2.2]octonium) achieve remarkably impressive average sensitivity of 6204 ± 268 µC Gyair -1 cm-2 and a low detection limit of 102.3 nGyair s-1, which makes highly effective for X-ray imaging. The sensitivity of recycled flexible devices not only matches that of single-crystal devices made with fresh materials but also ranks as the highest among all metal-free perovskite X-ray detectors. \"One-Click Restart\" applies to scalable flexible devices derived from aged single-crystal counterparts, offering significant cost, time, and energy savings compared to their single-crystal equivalents. Such advantages significantly boost future market competitiveness.
摘要：
卤化物钙钛矿由于具有优异的光电性能，在X射线检测中显示出巨大的潜力。然而,寻找一种具有成本效益和环境可持续的方法来处理报废设备仍然具有挑战性。这里,我们为报废钙钛矿X射线探测器引入了“一键重启”环保回收策略。这种方法,利用水,允许重新捕获和重复使用钙钛矿和导体材料。该过程简单明了，环保，消除了进一步化学处理的需要，净化,额外的添加剂或催化剂，复杂的设备。我们通过从回收材料中重建可穿戴电子设备的柔性钙钛矿膜，开发了一种可持续的设备循环。大规模,由无金属钙钛矿DABCO-N2H5-I3(DABCO=N-N'-二氮杂双环[2.2.2]八铵)制成的柔性膜在50V偏压下实现了6204±268μCGyair-1cm-2的显著令人印象深刻的平均灵敏度和102.3Gynairs-1的低检测限,这对X射线成像非常有效。回收柔性设备的灵敏度不仅与用新鲜材料制成的单晶设备相匹配，而且在所有无金属钙钛矿X射线探测器中排名最高。“一键重启”应用于从老化的单晶对应物衍生的可扩展柔性设备，提供巨大的成本，时间,和节能相比，它们的单晶等价物。这些优势大大增强了未来的市场竞争力。本文受版权保护。保留所有权利。
