Right: Schematic illustration of the molecular PV cell, with two donor LUMO levels. Left: Efficiency at maximum power ηmx as a function of hopping amplitude h between the donor LUMO levels and the acceptor LUMO (solid line) and hopping matrix element phase φ (dashed line), indicating the effect of quantum coherence on the efficiency for fully coherent D-A transfer (γD–A = 0). The dotted line is the same for a mixed coherent-incoherent transfer (γD–A ≠ 0).
