The paper studies spectral response of GaAs/Ge solar cells irradiated to 1.0×10
11
-3.0×10
12
cm
-2
by 100 keV protons
or irradiated to 3.0×10
12
cm
-2
by 50-170 keV protons.The results show that proton irradiation in- duces 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.
