FIELD: physics.
SUBSTANCE: invention relates to converters of optical and beta-radiation sources energy into electric energy. Invention provides creation of a two-way design of a combined photo- and beta-voltaic accumulating element consisting of superimposed on one silicon plate with one side a photocell and connected in parallel to it a planar flat capacitor, on the other side - a beta-voltaic element, beta-source nickel-63 of which is placed into microchannels for increasing the efficiency and the generation current.
EFFECT: such converter can be used in difficult to access places, mines, for power supply of biosensors integrated inside the body, et cetera.
