In this work, we measure PL decays from a GaAs subcell of a triple-junction solar cell for varied bias voltages. Additionally, results from a GaAs solar cell are used to quantitatively discuss the voltage dependence. We explain how the time constants are related to the electrical properties of the subcell.
