  • Abstract
    We report on the isothermal annealing behavior of 1 MeV electron irradiated component cells of a GaInP2/GaAs/Ge triple-junction solar cell. The defect concentration as a function of annealing time and temperature is derived from the in situ measured open-circuit voltages. The time-dependent behavior reveals the presence of partly overlapping exponential decays in defect concentration that, in turn, suggests the annealing of more than one defect having different activation energies.
