摘　　要：放射性同位素温差电池被认为是人类进行深空探测和月球探测最理想的能源供给器件。介绍了放射性同位素电源的工作原理、同位素热源的选择原则和各种热电转换技术的特点和研究现状,回顾了放射性同位素温差电池的各发展阶段。最后展望了空间用同位素电源的发展趋势,并认为在近期的深空探测任务中,MMRTG仍然会是能源系统的首选,其未来所需要解决的主要问题是热电转换效率的进一步提高和可靠性增长。Radioisotope thermoelectric generator （RTG） is the ideal power supply in the deep space exploration and the moon exploration. RTG working principle, selection of isotope heat resource and the characteristics and advances of various thermoelectric conversion technologies were introduced. The development of radioisotope thermoelectric generator was reviewed. Finally, the development trend of radioisotope thermoelectric generator for deep space exploration was prospected. It is considered that in the near future deep space exploration, MMRTG is still the first choice, and the main unsettled problem is to increase the efficiency of thermoelectric conversion and the reliability further.
