Efficiency at maximum power ηmx as a function of the position of the A-LUMO 
and the parameter ξ which describes the interpolation from coherent to incoherent electron D-A processes (see text).
Solid lines mark the coherent (tD–A = tmx, γD–A = 0), mixed (tD–A = tmx, γD–A = γmx) and incoherent (tD–A = 0, γD–A = γmx) donor-acceptor electron transfer processes. Dashed lines are guides to the eye, showing the position of the maximal efficiency for the different cases. Right inset: parameterization of tD–A and γD–A with ξ. Back inset: Efficiency as a function of the position of the A-LUMO 
at ξ = 0 (fully coherent system).
