Description

technical field [0001] The invention belongs to the field of isotope batteries, and relates to a radiation voltaic isotope battery, in particular to a SiC three-dimensional PIN structure radiation voltaic battery 3 H source isotope cell. Background technique [0002] The research on isotope batteries made a breakthrough in the 1950s, and they are widely used in aerospace, military, cardiac pacemaker and other fields. Since the British physicist Moseley made the first isotope battery successfully in 1913, many different types of isotope batteries have been developed. Radiovoltaic is one of the most common types of isotope cells. [0003] The basic principle of radiant voltaic isotope cells is similar to that of solar cells, the main difference is that the energy source of the latter is sunlight, while the energy source of the former is α or β rays emitted by the decay of radioisotope sources. Radiation voltaic isotope batteries have attracted attention at home and abroad b...
