Abstract

This paper presents the behavior of solar cells after successive gamma and neutron irradiation. Commercial solar panels have been exposed to gamma radiation and then, after 30 days of recovery, to neutron radiation. I-V characteristics, series and parallel resistance, open-circuit voltage, short-circuit current and fill factor have been measured before and after every step of irradiation. The process of annealing has also been observed. A comparative analysis of measurement results has been performed in order to determine the reliability of solar cells in radiation environments..
