no non-radiative recombination processes : The SQ limit only assumes radiative recombination as the only recombination channel for the cell, which is not the case in real materials.  The magnitude of these non-radiative recombination losses can be characterized by the internal fluorescence efficiency, via the formula:  $$  \nu_{int fluo} = \frac{R_{rad}}{R_{rad}+R_{non_rad}} \frac{R_{rad}}{R_{rad}+R_{non-rad}}  $$
