(Top) A simple 1D lattice model where the exciton can hop to neighboring sites with rate kHO, dissociate with rate kED(R), and relax to ground state with rate kR. (Middle) Exciton dissociation rate for an exciton at distance R from a cluster of acceptor molecules computed using Eq. 3 for different values of the attenuation factor β. (Bottom) Results of the kinetic model analyzed in terms of the probability that, when the electron dissociates, it dissociates at a given distance R.
