摘要
Abstract
Radioisotope batteries can achieve long-term stable power supply by utilizing the energy continuously released during the decay of radioactive nuclides,showing important application pros-pects in fields such as deep-space exploration,implantable medical devices,extreme-environment sensing,and microelectronic systems.In recent years,with the rapid development of wide-bandgap semiconductor epitaxial growth,radiation transport simulation,and micro-nano device fabrication technologies,materials including silicon carbide,gallium nitride,and diamond have become promis-ing candidates for high-performance radiovoltaic devices owing to their excellent thermal stability and strong radiation resistance.Meanwhile,perovskite-based materials and radiophotovoltaic cou-pling strategies have provided new ideas for material and structural design of novel nuclear micro-power sources.This paper systematically reviews the basic working principles of wide-bandgap radio-voltaic radioisotope batteries,the selection principles of radioactive sources,typical wide-bandgap material systems,and representative device structures.Future research trends are discussed focusing on the innovation of material systems,optimization of energy spectrum matching,and optimal struc-tural design.关键词
