COMPACT BETAVOLTAIC POWER SUPPLY OF LONG USE WITH BETA EMITTER ON BASIS OF RADIOISOTOPE 63 Ni AND METHOD OF OBTAINING IT Russian patent published in 2018 - IPC G21H1/02 G21H1/06 H01L29/66 

FIELD: electricity.

SUBSTANCE: compact betavoltaic power supply of long use with beta emitter, representing an assembly of "sandwich" structure in the form of a stack of alternating between each other single or complete current micro sources, where each of the current micro source contains siliceous n + alloy plate with p+ p epi layer, and the source of beta particles in the form of metal conductive layer, containing nickel-63 radioisotope, contacting with one or two sides with semiconductor converter, and a system of collector electrodes for connection to the load, wherein as the semiconductor converter of beta particles energy into electrical energy - matrix of single crystal p-silicon, and as a source of beta particles - commensurate with the semiconductor plate conducting metal plate, as a system of collector electrodes - the combination of system of internal silver linear electrodes, built-in form both sides of the silicon plate over the entire area on top of silicon nitride layer.

EFFECT: invention allows to increase the generated electric power, current and voltage of the betavoltaic source.
