“…Traditional batteries, such as fuel and solar cells, cannot satisfy the power requirements of MEMS devices due to their large volume, short lifetime, and poor environmental adaptability. A nuclear microbattery, which is used to transform the decay energy of radioisotopes into electrical energy, is a potential candidate as an energy supply for MEMS [1]. Among the numerous competing types of nuclear microbatteries, betavoltaic microbatteries have been extensively examined [2][3][4][5][6][7].…”

This article employs electrochemical deposition to prepare thermoelectric film materials to achieve a miniaturized radioisotope thermoelectric generator (RTG). First, the optimal composition and material properties are obtained by optimizing the deposition potential and the concentration of the electrolyte. The n‐type material can reach the highest thermoelectric power factor of 812.34 μW m−1 K−2 at a deposition potential of 0 V vs Ag/AgCl, and its composition is Bi1.92Te3.08. The highest power factor of 137.18 μW m−1 K−2 of the p‐type material is obtained when the ratio of the concentration of SbO+ to Bi3+ ions in the electrolyte solution is set to 6 with the deposition potential of −0.12 V vs Ag/AgCl. The composition is Bi0.68Sb1.24Te3.08. Then, a principle fan‐shaped RTG (FRTG) with an overall size of 11 mm (height) × 33.8 mm (diameter) is manufactured and tested. The FRTG generates an open‐circuit voltage of 170.21 mV, a maximum output power of 247.55 nW, and a temperature difference of 57.8 K at 1.5 W heat source. Compared with the RTG prepared by mechanical cutting in previous research, the FRTG exhibits a volume that is reduced by 12.45 times and a voltage that is increased by 60.71%.

Summary Radioluminescent nuclear battery has been widely studied for its miniaturization and long life. In this study, all‐inorganic perovskite quantum dots (CsPbBr3 QDs) were selected as a novel wave‐shifting agent combined with liquid scintillator PPO (2,5‐diphenyloxazole). The QDs were used to regulate the emission spectrum to match different GaAs devices. The maximum output power of the RL nuclear battery was greatly enhanced by 1.91 to 2.53 times. Perovskite QDs with adjustable emission spectra were used as wave‐shifting agents and exhibited more excellent properties and application prospects than traditional wave‐shifting agents. The Monte Carlo method was used to simulate the energy deposition of fluorescent materials under various radioactive source models. Results verified the advantages of using liquid radioactive sources and liquid fluorescent materials. The application and reference value of perovskite QDs in nuclear detection and nuclear medical imaging were also discussed.
