The former can be seen as one of the indicators for the initial polaron-pair yield and thus in line with the experimental results. The latter can be seen responsible for a charge recombination process. While the positive and negative charge of the exciton have to overcome the Coulomb barrier to be separated, the high CAE prevents charge separation and thus leads to recombination. To further explore the idea of the CAE being an indicator of recombination, we calculated the static CAE for PTB7 and PBB3 that were investigated by Carsten et al. The lower static CAE of PBB3 in the lowest excited states (Figure in the Supplementary Information) is in line with the experimental finding of long-lived excitonic states for this polymer, thus demonstrating the CAE to correlate to the experimental findings for different polymers. In terms of relatively simple quantifiers, it is therefore possible to associate the charge recombination and charge separation with CAE and dipole moment, respectively.
