AlGaAs 55 Fe X-ray radioisotope microbattery.

Scientific Reports 2016 December 7
This paper describes the performance of a fabricated prototype Al0.2 Ga0.8 As 55 Fe radioisotope microbattery photovoltaic cells over the temperature range -20 °C to 50 °C. Two 400 μm diameter p+ -i-n+ (3 μm i-layer) Al0.2 Ga0.8 As mesa photodiodes were used as conversion devices in a novel X-ray microbattery prototype. The changes of the key microbattery parameters were analysed in response to temperature: the open circuit voltage, the maximum output power and the internal conversion efficiency decreased when the temperature was increased. At -20 °C, an open circuit voltage and a maximum output power of 0.2 V and 0.04 pW, respectively, were measured per photodiode. The best internal conversion efficiency achieved for the fabricated prototype was only 0.95% at -20 °C.
