It is a matter of controversy why excitons can efficiently dissociate into free electrons and holes at an intrinsic donor-acceptor interface despite the strong Coulomb interaction between the charges provided by the low dielectric constant in organic materials. We suggest an analytic theory based on the recently developed exact solution for the dissociation problem [Phys. Rev. Lett. 100, 196602 (2008)] and show that delocalization of charge carriers along the polymer chains can help the… CONTINUE READING
