Abstract

The radiation resistance of individual InGaP and GaAs sub-cells is assessed as a function of base doping under low-energy proton irradiation. It is found that InGaP subcells with low base doping are the most radiation tolerant. However, in GaAs, carrier removal leads to a rapid degradation in sub-cells with low base doping and the most radiation hard sub-cell is achieved using a linearly graded base doping profile.
