Abstract A diamond p-n junction is used to convert the decay energy of $^{63}$Ni source into electrical energy. The self-absorption effect of the $^{63}$Ni source, the backscatter process and the transport process of beta particles in diamond materials are studied. Then the theoretical maximum of electrical properties and the energy conversion efficiencies of diamond-$^{63}$Ni p-n junction batteries are achieved. Finally, a feasible design of $p^{+}p^{-}n^{+}$ junction battery, which has the maximum output power density of 0.42 $\mu$W/cm$^{2}$ and the optimal device conversion efficiency of 26.8%, is proposed.
