摘要
为提升辐射伏特电池性能,研究了耗尽区宽度、扩散长度及电极结构等因素对输出功率的影响,并通过放射源厚度、换能器件结构、电极等方面的设计优化和工艺改进,制备获得了放射源与换能器件集成化的氚化钛-SiC基辐射伏特电池。与未集成化的氚化钛-SiC基电池的测试结果相比,氚化钛与换能器件集成化的方式显著提升了辐射伏特电池的输出性能,其中,最大输出功率达到了21.4 nW,在已公开报道的同类型辐射伏特电池中处于领先水平。本工作为制备高性能辐射伏特电池提供了有价值的参考。
To enhance the performance of betavoltaic batteries,we investigated the effects of depletion region width,diffusion length,and electrode structure on output power.By optimizing the design and improving the fabrication processes of radioisotope source thickness,converter structure,and electrodes,we successfully developed a tritiated titanium-SiC-based betavoltaic battery with the form of integrated radioisotope source and converter.Compared to the test results using a discrete tritiated titanium and a converter,the integrated approach of tritiated titanium and the converter significantly improved the output performance of the betavoltaic battery,achieving a maximum output power of 21.4 nW.This performance is among the highest reported for similar betavoltaic batteries.This work provides a valuable reference for developing high-performance betavoltaic batteries.
