Abstract

An AlGaAs/GaAs photovoltaic converter for a mock-up of an environmentally friendly radioisotope energy source of ultra-long use with a YPO4 :Eu/(238Pu) radioluminescent emitter with an extremely low content of the isotope 238Pu < 0.1 wt % was studied. The modeling of the Al0.8Ga0.2As/GaAs heterostructure for the conversion of nanowatt power levels of an optical signal has been carried out. The calculated and experimental efficiency of the mock-up with a photovoltaic converter at a radioluminescent source power of 1 nW was ~1.4%.
