Description

technical field [0001] The invention relates to the technical field of isotope cell packaging, in particular to a three-dimensional packaging structure for radiating photovoltaic isotope cells. Background technique [0002] Isotope battery is a special battery that uses the decay energy of isotopes to convert into electrical energy. It has the advantages of compact structure, small size, long life, high reliability and maintenance-free. Ideal power supply for long-term power supply in deep space. At present, isotope batteries are mainly divided into direct conversion and indirect conversion according to the conversion mechanism. Among them, radiative photovoltaic indirect conversion isotope cells have practical application value in micro-isotope cells because of their high reliability. [0003] Radiation photovoltaic isotope cell refers to a device that uses radioactive decay rays to interact with fluorescent substances to generate fluorescence, and then converts the decay...
