“…The nuclear battery is widely used in severe environments such as outer space and deep sea, because of its small size, light weight, long service life, and stable output power 1‐4 . At present, miniaturized nuclear batteries mainly consist of decay particle conversion mechanism; however, radiovoltaic nuclear battery with direct conversion mode causes severe displacement damage of the semiconductor unit and shortens its service life 5‐8 .…”

Summary This work investigated the preparation and optimization of phosphor layer for radioluminescent nuclear battery, and analyzed the property change of the phosphor after irradiation. ZnS:(Cu, Al) with grain size of 5 μm was selected as the phosphor material, and AlGaInP semiconductor was used as the photovoltaic unit. Monte Carlo modeling was used to simulate energy deposition, absorbed dose, penetration of β particles in the phosphor. The optimized coupling scheme of radioisotope sources and phosphor layer was obtained based on comparison particle penetration depth and the output power of radioluminescent nuclear battery. The phosphor layer with 60Co γ‐radiation enhanced the luminescence property up to 50% at the radiation dose of 871 kGy, which is considered as an optimized method of phosphor layer preparation. The radiation of 10 MeV electron was conducted to study the degradation based on the microscopic lattice characteristics, morphological changes, optical and electrical properties. Phosphors have excellent radiation resistance. The output power of nuclear batteries has only declined by 43% even when electron radiation dose reaches 8.56 MGy. The prospect for utilizing ZnS:(Cu, Al) phosphor as radiant energy conversion materials in nuclear battery was also discussed. Results provided an effective guideline for predict the service conditions of radioluminescent nuclear battery.

“…The main difference between the 2 types of batteries is that the former adds an intermediate energy conversion process, while the integrated battery structure adds a phosphor layer. So the whole energy conversion process of radioluminescent nuclear battery is from nuclear energy to light energy, and then again to electric energy . It works because phosphor layers can emit visible light under radioactive particles excitation, and the light is powerful enough to knock electrons free from atoms.…”

Summary Radioluminescent nuclear battery is a type of energy conversion device that can be miniaturized, which has the ability to convert nuclear energy into light energy, and again into electrical energy. To explore the response relationship between the phosphor layer structure and the electrical performance of radioluminescent nuclear battery, the physical model was established to research the deposition energy distribution by using Monte Carlo method. The radioluminescence spectra and current‐voltage characteristic curves were used to investigate the optical and electrical properties. Through a comprehensive comparison of single plane layer, double plane layer, and V groove layer structures, the simulated results are consistent with experimental results. The results indicate that the Monte Carlo simulation is applicable to analysis of the phosphor layer structure of radioluminescent nuclear battery. Additionally, the results also show that the structure type and physical parameters of the phosphor layer have great influence on the energy deposition. A suitable phosphor layer structure can provide a new route to exhibit higher energy conversion efficiency as well as improving the matching degree between the range of radioactive particles and the thickness of the phosphor layer.

“…Increasing the activity and choosing a radioactive source of high‐energy are the most direct ways to improve the output performance of nuclear cells to meet the power requirements of MEMS. Previous studies have shown that the particles (α, β, γ, and X‐ray) decayed from the radioactive source can easily make radiation damage on the semiconductor for the radiovoltaic nuclear battery with direct energy conversion …”

Novel radioluminescent nuclear battery: Spectral regulation of perovskite quantum dots

CsPbBr 3 and CsPbBr 1.5 I 1.5 perovskite quantum dots (QDs) are synthesized by hot-injection with PPO (2,5-diphenyloxazole) as a fluorescent material for radioluminescent nuclear battery. The results reveal that the fluorescence of the QD/PPO system consists of radioluminescence (4.79%-5.35%) and photoluminescence (nearly 95%). The addition of QDs leads to more excellent optical and electrical properties of radioluminescent nuclear battery. The peak position of the radioluminescence spectra of QD/PPO can be regulated by controlling the components of QDs. This strategy is suitable for obtaining a satisfactory spectral matching factor for different photovoltaic devices to obtain outstanding output performance. Moreover, good selection of QD/PPO as a fluorescent material can significantly improve the overall output performance of the radioluminescent nuclear battery. The linear relationship between optical and electrical properties was presented. Perovskite QDs exhibit excellent application prospects for the (α, β, γ, and X-ray sources) radioluminescent nuclear battery and X-ray imaging technology.
