Title: Computer simulations of the proton irradiated (AlGa)As-GaAs solar cells

Abstract

An improved numerical model for computing the displacement defect density, the damage constants for the minority-carrier diffusion lengths and the degradations of the short-circuit current I/sub sc/, open-circuit voltage V/sub oc/, and the conversion efficiency eta/sub c/ in a proton irradiated (AlGa)As-GaAs solar cell is presented in this paper. The model assumed that the radiation-induced displacement defects form effective recombination centers which reduces the minority-carrier diffusion length and hence degrades the I/sub sc/, V/sub oc/, and eta/sub c/ of the solar cell. Excellent agreement was obtained between our calculated values and the measured I/sub sc/, V/sub oc/, and eta/sub c/ in the proton irradiated GaAs solar cells for proton energies varying from 100 keV to 10 MeV and fluences from 10/sup 10/ to 10/sup 12/ cm/sup -2/ under normal incidence condition.
