Description

The paper studies spectral response of GaAs/Ge solar cells irradiated to 1.0 x l011-3.0 x 1012 cm-2 by 100 keV protons, or irradiated to 3.0 x 1012 cm-2 by 50-170 keV protons. The results show that proton irradiation induces a great damage in optical characteristics of the solar cell, resulting from the large quantity of irradiation defects that would destroy crystal lattice integrity and reduce the diffusion distance of minority carrier, and thus increase the surface recombination velocity. The damage extent of GaAs/Ge solar cell increases with proton energy and dose in their ranges under investigation. (authors)
