Query: I-V analysis of high-energy lithium-ion-irradiated Si and GaAs solar
  cells   Space-grade Si and GaAs solar cells were irradiated with 15 and 40 MeV
lithium ions. Dark-IV analysis (with and without illumination) reveals
differences in the effects of such irradiation on the different cell types
