WebGaAs/GaSb tandem cells stacks have been irradiated by 3 MeV electrons. BOL efficiency of the cells for this experiment was 25.5 – 26.2% (AM0, 100 suns). The 17.5% EOL efficiency and 0.68 remaining factor of efficiency have been recorded in the GaAs/GaSb tandem after 1·1015cm-23 MeV electron exposure (Fig. 8).
