In this paper, we present data on the electrical properties of 50 mu m thick space silicon BSFR cells irradiated with 10 MeV protons with a fluence exceeding 1*1013 p/cm2 and irradiated with 1 MeV electrons with a fluence exceeding 1*1016 e/cm2, and discuss the anomalous degradation which was found in these large-fluence regions. These data show an increase of saturation current density and a decrease of diffusion voltage of the pn junction, and a decrease of majority carrier density and an increase of series resistance of the p-substrate as a result of the formation of a large amount of carrier traps by the large-fluence irradiation.
