Thermoelectric Optimized Efficiency At Strong Coupling In Nano-sized Photo-electric Device

In this work we consider a model of solar energy converter which is composed of a nanoscalernphoto-electric device having two energy levels in contact with two electron reservoirrnleads at the same temperature but with different chemical potentials whose task is tornconvert radiation energy to electric energy. We analytically study the optimized thermodynamicrnefficiency, which lies between Carnot efficiency and efficiency at maximumrnpower, of our model displaying strong coupling between the generated electron flux andrnthe incoming photon flux from the sun. We also find the time taken to accomplish onerncomplete cycle at the maximum power and at optimized efficiencies
