  • Abstract
    In this paper, cathodoluminescence (CL) spectra were measured on p+n GaAs solar cells after irradiation by protons at different fluences and energies. A damage constant (τ0Kτ) is determined at each proton energy by monitoring changes in the emitted CL intensity. The energy dependence of the CL damage constant is compared with the calculations of nonionizing energy loss (NIEL). It was found that the energy dependence of the CL damage constant closely tracks that for the open circuit voltage.
