Photovoltaic nuclear electric battery based on single-crystal diamond core activated with carbon-14

The fabrication of a photovoltaic nuclear electric battery consisting of a radioactive diamond core and an InGaP photoconverter is described. An electrical circuit for a nuclear battery has been proposed. A battery core has been manufactured using a polished self-glowing diamond plate made of artificial single-crystal IIb-diamond activated with 0.008 wt. % 14C. The optimal geometric parameters of the proposed diamond plates have been determined, and a prospective photovoltaic converter was developed. The optimal design of the nuclear diamond battery, including possible increase in power yield, is discussed.
