  • 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 which in turn suggest the annealing of more than one defect having different activation energies.
