FIELD: power engineering.
SUBSTANCE: invention relates to power engineering and can be used for conversion of radioactive energy into electric one. High-voltage electric power supply source with long service life contains an insulating housing accommodating a primary semiconductor converter with placed above its surface 63Ni isotope connected with two output terminals arranged on the housing. Herewith the primary converter is made in the form of a structured polycrystalline film from semiconductor compounds of AIIBVI applied on an insulating substrate.
EFFECT: technical result is higher level of specific output voltage of the radioisotope electric power supply source while providing satisfactory mechanical properties.
