“…This tendency has been observed in previous studies [22][23][24][25]; as thickness increases, the self-absorption effect appears, and the beta particle fluence and total energy deposition are influenced by it. Above 10 μm, the thickness does not affect beta particle fluence, and fluence remains constant around 2.63 × 10 9 particles/cm 2 s at layer 'A' and 1.75 × 10 9 particles/cm 2 s at layer 'B'.…”

Summary Multi‐layered Ni‐63 betavoltaic cell was investigated for improving the current density and the source efficiency. The model of betavoltaic cells, which typically consist of Ni‐63 radioisotope source, semiconductors, and electrodes, was built using MCNP6, and the emission and absorption behaviours of beta particles throughout the cell were analysed with changing geometrical shape of the betavoltaic cell and thickness of radioisotope source layer in order to achieve the improved current density and efficiency of the cell. The result showed that the fluence of beta particles generally increases with the increase of radioisotope thickness up to 10 µm in both rectangular and cylindrical geometry, while it remains nearly constant above the specific thickness because of the self‐absorption effect. Moreover, the results showed that current density of betavoltaic cell could be achieved in cylindrical geometry (1.67 μA/cm2) comparing with rectangular one (1.54 μA/cm2) based on the optimum thickness of Ni‐63 radioisotope thickness with the consideration of self‐absorption.

This paper investigates the effects of temperature on an InGaP (GaInP) 55Fe X-ray photovoltaic cell prototype for a radioisotope microbattery (also called a nuclear microbattery). An In0.5Ga0.5P p-i-n (5 μm i-layer) mesa photodiode was illuminated by a standard 206 MBq 55Fe radioisotope X-ray source and characterised over the temperature range −20 °C to 100 °C. The electrical power output of the device reached its maximum value of 1.5 pW at a temperature of −20 °C. An open circuit voltage and a short circuit current of 0.82 V and 2.5 pA, respectively, were obtained at −20 °C. While the electrical power output and the open circuit voltage decreased with increasing temperature, an almost flat trend was found for the short circuit current. The cell conversion efficiency decreased from 2.1% at −20 °C to 0.7% at 100 °C.
