We theoretically investigate an exciton-coupled electron transfer (XCET)process that is conversion of an exciton into a charge transfer state. Thisconversion happens in an exciton transfer (XT) process, and the electron movesaway in an electron transfer(ET) process in multiple environments (baths). ThisXCET process plays an essential role in the harvesting of solar energy inbiological and photovoltaic materials. We develop a practical theoretical modelto study the efficiency of XCET process that occurs either in consecutive orconcerted processes under the influence of non-Markovian baths. The role ofquantum coherence in the XT-ET system and the baths is investigated usingreduced hierarchal equations of motion (HEOM). This model includes independentbaths for each XT and ET state, in addition to a XCET bath for the conversionprocess. We found that, while quantum system-bath coherence is important in theXT and ET processes, coherence between the XT and ET processes must besuppressed in order to realize efficient irreversible XCET process through theweak off-diagonal interaction between the XT and ET bridge sites arises from aXCET bath.
