摘要: The displacement damage dose methodology for analysing and modelling the performance of triple-junction InGaP2/GaAs/Ge solar cells in an electron radiation environment is presented. Degradations at different electron energies are correlated with displacement damage dose (D_\rm d). One particular electron radiation environment, relative to a geosynchronous earth orbit (GEO), is chosen to calculate the total D_\rm d behind the different thicknesses coverglasses to predict the performance degradation at the end of the 15-year mission.

Abstract: The displacement damage dose methodology for analysing and modelling the performance of triple-junction InGaP2/GaAs/Ge solar cells in an electron radiation environment is presented. Degradations at different electron energies are correlated with displacement damage dose (Dd). One particular electron radiation environment, relative to a geosynchronous earth orbit (GEO), is chosen to calculate the total Dd behind the different thicknesses coverglasses to predict the performance degradation at the end of the 15-year mission.

Key words: nonionizing energy loss, displacement damage dose, solar cell
