Abstract
The radio-voltaic effect is investigated to be applied radioisotopic batteries in this work. The collection rates of the electron-hole pairs are 94 percent for the alpha particles emitted by239Pu source and 65 percent for the beta particles emitted by90Sr-90Y source. The maximum energy conversion efficiency got by the silicon element is about 16%. A prototype radioisotopic battery with147Pm beta sources is constructed. Its maximum short-circuit current and off voltage are about 2μ A and 190 mV respectively. The experimental data suggest that the life of the prototype battery may be more than three years.
