Description

technical field [0001] The invention belongs to the technical field of isotope batteries, in particular to a modular radiovoltaic isotope battery. Background technique [0002] The research on radiovoltaic isotope batteries began in the 1950s. Since the 1970s, the research on radiovoltaic isotopes has become a hot spot in the field of micro self-power supply system research. Developed countries have invested a lot of manpower and financial resources in research , especially in the United States, the Department of Defense, the Department of Aeronautics and Space, and the Department of Energy invest tens of millions of dollars every year to organize weapons laboratories (Sandia Laboratories, Army Research Laboratory), universities (Cornell, Wisconsin, California, Rochester, etc.) and companies (Bettabatt, Widetronix, Citylabs, Qynergy) to carry out long-term research (M.A. Prelas et al., Progress in Nuclear Energy [J], 7, 4, 2014; L.L.

[0006] In 2004, U.S. Patent 6753469 reported that a diamond PN junction was used as an energy conversion device for a high-energy β and α isotope radiation volt special effect battery. The N-type layer and the P-type layer of the diamond device were each about 10 μm thick, and the doping concentration was low (10 15 ~10 14 / cm 3 , or even lower), but the preparation of diamond PN junction devices is very difficult, the cost is high, and it is not easy to popularize and apply

[0009] However, Liu Yebing's patent only gives the basic structure of the basic functional parts of the battery, and does not give the modular structure, the electrical interconnection and electrical lead-out inside the module, the structure and method of the electrical interconnection and electrical lead-out between modules, and does not propose sealing requirements. , did not propose multi-dimensional anti-seismic materials and structures; secondly, Liu Yebing’s patent did not propose the control of the atmosphere environment in contact with the active surface of the semiconductor device inside the battery; in addition, Liu Yebing’s patent is aimed at radiation-induced photoluminescence—combination of photovoltaic conversion and radiation-volt conversion conversion, did not propose the applicability of radiation-induced photovoltaic conversion; again, Liu Yebing’s patent did not propose the applicability to isotopes Cs-137, Sm-151, Eu-152 / Eu-154, nor did it propose the application of mixed isotopes Thirdly, Liu Yebing’s patent did not mention the applicability to crystals of inorganic oxides, sulfides, and halides; at the same time, the patent’s applicability to semiconductor device materials, junction types, junction numbers, and substrate materials is limited
