In this work, we measure photoluminescence decays from the top InGaP and middle GaAs subcell of triple-junction solar cells with different proton damage. The characteristic time constants are obtained from excitation power dependence and compared with the current-voltage curves of the total device. We explain how the time constants are related to the electrical properties of the subcell.
