Abstract :
A method for determining the luminescence coupling between subcells in a multi-junction solar cell is presented. The method measures the luminescent intensity for various optically and electrically generated currents. The luminescence coupling can then be derived straightforwardly by pairing the electrically biased and optically biased currents at a given output intensity.
