Abstract: A new theoretical model of gamma ray photovoltaic cells is presented with calculations of efficiency η, open circuit voltage V∞, and maximum output power P0max. The model incorporates a scintillator interfaced between the high-energy nuclear isomer and the semiconductor materials of the photovoltaic cell. High-energy γ-photons, E γ1 = 1:333 MeV and E γ2 = 1:173 MeV, emanate from nuclear isomers Nickel-60m1/m2 of Nickel-60 in Cobalt-60 decay. The scintillator converts the γ-photons into large numbers of low-energy photons. The latter photons illuminate the semiconductor materials of the photovoltaic cell. Such devices can have enhanced η, V∞, and a much longer operational life than those driven by Thorium-229m1/m2. Results are reported for devices with scintillators of various maximum emission wavelengths λmax and yields y. One mol of Cobalt-60, combined with a high-y and short-λmax scintillator, can produce V∞ ~ 10V and P0max of several hundred W/m2 to few times the AM0 power at about 70%. These are signi...

TL;DR: A review of the current state of the knowledge regarding the use of radioactive sources to generate photonic light in scintillators as converters of ionizing radiation to electricity in photovoltaic cells is presented in this paper.
Abstract: This review presents the current state of the knowledge regarding the use of radioactive sources to generate photonic light in scintillators as converters of ionizing radiation to electricity in photovoltaic cells. The possibility of using the phenomenon of the excitation of light photons in the scintillation materials during the interaction with particles and photons of ionizing radiation was analyzed in detail. The light photons obtained in such a way can generate an electric charge in photovoltaic cells. The whole process can be named as a nuclear cell (nuclear battery). Theoretically, the use of such physical phenomena seems to be an ideal practical solution to meet the energy needs of the modern world. However, there are many physical and technical problems that limit its widespread use in practical applications. In an ideal system, the ionizing radiation sources can emit the radiation for billions of years, and the energy of particles and photons from the radiation can be converted into photons in the scintillation material, with energy suitable to generate a photoelectric effect in a photovoltaic cell. Such a cascade sequence of different physical phenomena allows, from a theoretical point of view, for the creation of a virtually inexhaustible source of electricity. This review of historical and current literature reports aims to bring closer the idea of “energy perpetuum mobile”, which has troubled many scientists around the world for centuries.
