Abstract

The invention provides a radiofluorescence isotope battery and a manufacturing method of theradiofluorescence isotope battery, and belongs to the technical field of isotope batteries. The radiofluorescence isotope battery comprises an isotope source, a first scintillator and a first photovoltaic cell, the first scintillator is of a blocky structure made of a single crystal material, a first metalreflection layer is plated on the first surface of the first scintillator, and the first surface of the first scintillator is connected with the first surface of the isotope source. Compared with theprior art, the blocky bulk single crystal structure is higher and more stable in light emitting efficiency, part of light generated by the first scintillator can be reflected to the second surface ofthe first scintillator through the first metal reflection layer, and then the photon collection efficiency of the first photovoltaic cell is improved.

Description

technical field [0001] The present application relates to the technical field of isotope batteries, in particular, to a radiation-induced fluorescence isotope battery and a method for manufacturing the radiation-induced fluorescence isotope battery. Background technique [0002] At present, small and micro isotope cells are mainly composed of radiation voltaic effect isotope cells and radiofluorescence isotope cells. Radiation fluorescence isotope cells are composed of isotope sources, scintillators and photovoltaic cells. The scintillator converts the radiation particles emitted by the isotope source into light energy, and then the photovoltaic cell converts the light energy into electrical energy for output. Since a scintillator is used for an energy conversion, the radiation emitted by the radioactive source does not directly act on the photovoltaic transducer unit, so compared with the low-energy β source used in the radiovoltaic effect isotope cell, the radiofluorescenc...
