Electron and omnidirectional proton irradiations of AlGaAs-GaAs solar cells

Space use of GaAs solar cells is subordinated to a better knowledge of the degradation due to ionizing particles. Omnidirectional fluxes of 10MeV protons are simulated in our experiments. I-V curves and DLTS measurements are carried out on the same device. Results obtained on AlGaAs-GaAs cells are compared with the degradation due to 1 and 2-MeV electrons. Challenge with silicon solar cells is discussed. 10-MeV proton irradiations give lower degradation of photovoltaic parameters in AlGaAs-GaAs solar cells than in Si solar cells. Electron damages are of the same order of magnitude. Coefficients of equivalence for Isc are deduced from these results.
