no **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:
\[ \nu_{int\;fluo} = \frac{R_{rad}}{R_{rad}+R_{non-rad}} \]
To maximize \(\nu_{int\;fluo}\) we have to minimize \(R_{non-rad}\), which means optimizing the carrier lifetime for the recombination process. This can be modelled via 3 processes: the Shockley-Read-Hall (SRH), band to band, and Auger.
