Abstract
Recently, it has been experimentally demonstrated that an order of nongeminate recombination exceeds two in some types of organic bulk heterojunction donor-acceptor structures. This result is different than for the case of bimolecular recombination described by Langevin theory. Although several theoretical explanations of this effect have been presented, the origin of higher recombination orders is still questionable. In this work, we analyze the process of interaction between an exciton and a polaron and its role in the increasing of recombination order. The influence of a charge concentration effect on mobility is discussed.
