title: The effect of temperature changes on electrical performance of the betavoltaic cell.
abstract: There is a significant relationship between temperature and electrical performance of a betavoltaic cell. Two silicon diodes used as energy conversion devices of betavoltaic cells were irradiated by Ni-63, and the relationships between the temperature and the electrical performance such as V(oc), I(sc), and P(max) were examined. I(sc) increased very little as temperature increased but V(oc) decreased considerably. The changing values of V(oc) were -3.1 and -3.0 mV/K, respectively, in the temperature range 233.15-333.15 K. As a result of this, P(max) and eta also decreased markedly.
