论文摘要
高能和高强度电离辐射的检测和直接功率转换可能是下一代核反应堆安全系统和太空式设备的关键要素。例如，如果1 \％的残留辐射（核裂变的$γ$ - 砂）直接在反应堆内转换为电力以为水冷却电路供电，那么2011年的福岛灾难可能会在很大程度上被预防。在这里据报道，三碘化物杂种卤化物钙钛矿甲基铵铅可以完美地发挥转换器的作用。单晶被典型的核反应堆的典型关闭$γ$ -Spentrum（7.61E14 BQ活性）表现出高效$γ$ -ROAR-ray-radiation harking harking harking的高效载体。 0.3 mW/kg的甲基铵铅三碘化物的功率密度是50 sv/h的铅含量，是基于硅细胞的效率的四倍。该材料稳定在实验的限制下，而没有将其性能最高为100 SV/h剂量率和57 SV H*（10）环境总计$γ$剂量。此外，发现三碘化甲基铵铅的γ屏蔽性能优于普通和少石混凝土。
Detection and direct power conversion of high energy and high intensity ionizing radiation could be a key element in next generation nuclear reactor safety systems and space-born devices. For example, the Fukushima catastrophe in 2011 could have been largely prevented if 1\% of the reactor's remnant radiation ($γ$-rays of the nuclear fission) were directly converted within the reactor to electricity to power the water cooling circuit. It is reported here that the hybrid halide perovskite methylammonium lead triiodide could perfectly play the role of a converter. Single crystals were irradiated by a typical shut-down $γ$-spectrum of a nuclear reactor with 7.61E14 Bq activity exhibit a high-efficiency of $γ$-ray to free charge carrier conversion with radiation hardening. The power density of 0.3 mW/kg of methylammonium lead triiodide at 50 Sv/h means a four times higher efficiency than that for silicon-based cells. The material was stable to the limits of the experiment without changing its performance up to 100 Sv/h dose rate and 57 Sv H*(10) ambient total $γ$-dose. Moreover, the γ-shielding performance of methylammonium lead triiodide was found to be superior to both ordinary and barite concrete.
