Abstract
The invention discloses a radioisotope cell based on a gaseous radioactive source. The radioisotope cell comprises a glass container filled with the gaseous radioactive source, a light emitting layer deposited on the inner wall of the glass container and a photovoltaic conversion unit arranged on the outer wall of the glass container. The glass container is filled with gaseous radioisotopes which can perform spontaneous decay and emit radioactive particles. The light emitting layer is used for absorbing the radioactive particles and converting energy of the radioactive particles into optical energy. The photoelectric conversion unit is used for converting light emitted by the light emitting layer into electric energy. The radioisotope cell is reasonable in design, long in service life, high in energy density, low in maintenance cost and strong in anti-jamming capability, and provides the basis for producing commercial radioisotope cells.
Description
Technical field
The present invention relates to a kind of radioisotope battery, particularly relate to a kind of radiosiotope based on gaseous state radioactive source
Battery.
Background technology
At present, the domestic radioisotope battery production capacity the most not possessing commercialization.And radiosiotope commercial in the world
Battery mainly has radioisotope thermoelectric battery and spoke two kinds of battery of volt, but radioisotope thermoelectric battery is difficult to miniaturization, and the core of miniaturization is same
It is a kind of that position element battery only has spoke volt battery.
In current research, spoke volt battery is primarily present three problems, and one is that output is the lowest, at tens nw magnitude models
Enclose；Two is that battery life is far below life expectancy, is significantly shorter than the radioisotopic half-life；Additionally, the energy of battery turns
Change efficiency the lowest, typically smaller than 2%.It is very limited that the most several factors result in its range of application.Over nearly 10 years, have
Researcher proposes the isotope battery of radioluminescence associating photovoltaic effect, physically by radiant absorbing material and electric energy
Generation unit realizes separating, thus effectively prevent the irradiation damage of electric energy generation unit, substantially increases the longevity of isotope battery
Life.
But the isotope battery of radioluminescence associating photovoltaic effect is the most rare.Although abroad there being use field of solid state radiation
Source excitation noble gas is luminous, then converts light energy into the technology of electric energy with photovoltaic device, yet with field of solid state radiation source from
Absorption effect is the highest, and the film thickness in usual field of solid state radiation source is less than 5um, therefore causes radioisotopic loading
The lowest, the output of battery is the lowest.The luminous intensity also resulting in noble gas is more weak, and photovoltaic device can only operate in low
Efficiency is interval, and therefore the integral energy transformation efficiency of isotope battery is the highest.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of radioisotope battery based on gaseous state radioactive source, its
There is battery length, output is high, energy density high, maintenance cost is low and capacity of resisting disturbance is strong remarkable advantage.
For achieving the above object, the technical solution used in the present invention is as follows:
Radioisotope battery based on gaseous state radioactive source, including being filled with the glass container of gaseous state radioactive source, is coated in this glass
Luminescent layer on glass container inner wall, and it is arranged on the photoelectric conversion unit on glass container outer wall；Fill in described glass container
There is the gaseous state radiosiotope that can produce radioactive particle with spontaneous decay, and luminescent layer is used for absorbing radioactive particle, and will
The energy conversion of radioactivity Semen Castaneae is luminous energy；Described photoelectric conversion unit is transformed into electric energy for the light sent by luminescent layer.
Further, described luminescent layer uses fluorescent material, phosphor material or semiconductor-quantum-point material to make.
As preferably, described photoelectric conversion unit is Organic substance photovoltaic device, perovskite photovoltaic device, dye-sensitized photovoltaic device
With any one in inorganic photovoltaic device.
Compared with prior art, the method have the advantages that
(1) the highest due to solid-state Atom density, therefore field of solid state radiation source is the biggest to the self absorption factor of radioactive particle.And
The present invention uses gaseous state radioactive source, can reduce atomic density, thus can reduce the radiosiotope self-priming to radioactive particle
Adduction, improves radioisotopic loading, thus improves the output of battery；Gaseous state radiosiotope is filled out simultaneously
Fill deposition on inwall and have the glass container of luminescent layer, that is luminescent layer four sides is around radiosiotope, therefore can realize putting
Whole absorptions of penetrating property particle, and excitation photon energy, finally by the luminous energy electric energy transduction of photoelectric conversion unit, produce
Electric current.The present invention can reach 100% to the theoretical absorption rate of radioactive particle, and radioisotopic loading is greatly improved simultaneously
Amount, improves output and the energy conversion efficiency of battery.
(2) owing to depending on the radiation-damage stability energy of radioisotopic half-life length and battery the service life of battery.
The structure design of the present invention solves irradiation damage problem, has therefore reached the desired life of isotope battery its service life, i.e.
More than two radioisotopic half-life, an implanted work system, it is not required in whole battery lifetime change.
(3) energy density of the present invention is high, maintenance cost is cheap, capacity of resisting disturbance is strong, and it acts not only as some extreme environment
Such as deep space, deep-sea exploration, the energy resource supply of polar region exploration, closed system such as cardiac pacemaker etc., solve micro-, mini-system
Energy resource supply problem, and fully rely on radioisotope decays produce energy work, because of without extra energy
Supply such as light, heat, vibration etc., therefore range of application is extremely wide.
