Annotation The basic technical principles and means of increase in betavoltaitic elements effectiveness have been analyzed by comparing with their closest analogue – photoelectric semiconductor converters. The geometric parameters of radiation sources for these elements and their capacities have been estimated. It is shown the radiation source 63Ni foil thickness should not exceed a few micrometers, and maximum energy conversion efficiency can achieve ~ 16 %.
