Abstract
In this paper, the theory of the transfer efficiency of a light-harvesting system consisting of a trimer ring coupled to an acceptor site is presented. When the ring has a prepared excitation or is excited using a laser pulse, the maximum transfer efficiency is approximately 0.5, while a near-perfect transfer efficiency is generated by a single photon. The near-perfect efficiency results from the creation of a dark state by the photon, which suppresses the effect of spontaneous decay from the donor.
