摘要: 微机电系统、深空、深海探测任务等对于长效、便携电源提出了更高的要求。同位素电池由于其能量密度高、功率输出稳定,可以在高低温、无太阳光照等极端环境下持续不断地为月球车、海底探测器等提供能量。作为同位素电池中的主要类型,辐射伏特效应同位素电池由于其理论能量转换效率高、易于微型化被广泛研究,并已经成功应用于心脏起搏器。宽禁带的半导体换能结器件制作的同位素电池能够获得更高的能量转换效率。宽禁带半导体中的代表金刚石具有5.5 eV的禁带宽度与耐辐射的特性,使其成为制作辐射伏特效应同位素电池换能结器件的最佳选择。随着化学气相沉积技术的发展,金刚石晶体的外延技术突飞猛进,为金刚石半导体器件的发展打下了材料基础。本文对比了常见的同位素电池换能结用半导体材料和辐射源材料的特性,介绍了辐射伏特效应的基本原理,接着对辐射伏特效应同位素电池的关键参数进行了分析,并汇总了有关金刚石辐射伏特效应同位素电池研究的文献,通过各个参数,如开路电压、转换效率等的对比,指出了目前金刚石同位素电池发展的状态与存在的问题。通过分析金刚石与其他n型半导体材料组成的异质pn结目前的性能与应用情况,给出了基于金刚石异质pn结的高性能同位素电池的结构设计,并进行了总结与展望。

Abstract: MEMS, deep space and deep sea exploration tasks put forward higher requirements for long-term and portable power supply. Due to its high energy density and stable power output, isotopic battery can continuously provide energy for Lunar Rover and seabed detector in extreme environments such as high and low temperature and no sunlight. As the main type of isotope battery, radio-voltaic effect isotope battery has been widely studied because of its high theoretical energy conversion efficiency and easy miniaturization, and it has been successfully applied to cardiac pacemaker. The isotope battery made of energy converters using semiconductor with wide band gap can obtain higher energy conversion efficiency. The 5.5 eV band gap and radiation resistance of single crystal diamond make it the best choice for making energy converters for radio-voltaic effect isotope batteries. With the development of chemical vapor deposition technology, the epitaxial technology of diamond crystal has made rapid progress, which has laid a material foundation for the development of diamond semiconductor devices. The characteristics of common semiconductor materials for energy converters and radiation source materials for isotopic battery are compared in this paper, the basic principle of radio-voltaic effect is introduced, then the key parameters of radio-voltaic effect isotopic battery is analyzed, and the literatures on the research of diamond radio-voltaic effect isotopic battery are summarized.
