29. The actual electroluminescence efficiency can be much more complicated than Eq. (7). The cross recombination terms are included in Eq. (7) for the reason to be discussed in more detail in the next paragraph. In short, to avoid further complications in the model, we consider that the recombination ultimately occurs at the same molecule from the decay of the excited state to the ground state even though the charge carriers may transport through different molecules.
