Interestingly, with the attachment of a second proton to a given PCPDT-BT chain, we find that for certain spatial arrangement of the two protons, a polaron state is induced in the conjugated chain that is largely spatially decoupled from the proton sites. Similar behavior is found if the electron transfer process leaving the positive polaron behind occurs on an individual chain as an intrachain electron transfer process or between a protonated and an un-protonated chain as an interchain transfer process. In a film environment, we reckon that the polaron induced in this fashion would be able to move and act quite freely as a positive charge carrier, not tied to its site of origin. To further relate our theoretical results to the experimental observations, we also calculate the optical absorption spectra of doped PCPDT-BT. Taking into account species with different amounts of protonation, our results help to explain the experimentally observed doping induced spectral features in detail. We believe that the results reported in the present work will help to further clarify the microscopic mechanisms discussed in the literature to explain the potentially high efficiency achieved by doping OSC materials with Lewis acids.
