Fabrication and performance optimization of SiC-based betavoltaic batteries by HE Houjun, HAN Yuncheng, WANG Xiaoyu, REN Lei, MENG Xiangdong, ZHENG Mingjie

“…BackgroundBetavoltaic nuclear batteries, leveraging beta-emitting radioisotopes, offer inherent advantages such as long-term reliability, high energy density, compact form factors, and robust resistance to interference, positioning them as promising power sources for self-powered portable or embedded microdevices.PurposeThis study aims to enhance the conversion efficiency and output power of betavoltaic batteries with comprehensive consideration of the effects of backscattering, depletion region width, diffusion length, and electrode structure on charge collection efficiency, conversion efficiency, and output power.MethodsBy optimizing the device and electrode structure, i.e., introducing a PIN structure with "concentration gradient I- layer", optimizing the depletion region width, doping concentration and electrode materials, and increasing the spacing between electrode grid lines, 63Ni-SiC-based PIN junction betavoltaic batteries were successfully fabricated with higher overall conversion efficiency and output power. …”
