2.6.3 Interfacial SRH Recombination

The SRH expression needs modification if one wants to use that formalism at an interface. By interface, we mean the interface between the selected layer and the layer to the right. At such an interface, trapping and de-trapping can occur to either side of the interface. This is valid for every layer except for the rightmost layer, where there is an interface with the electrode. There we do not take interfacial SRH recombination into account. In order to take all these possible processes into account, we have re-derived the SRH expression. Details can be found in Koopmans et al. in Ref.  [ 3 ] .
