Abstract: Abstract In this work we consider a model of solar energy converter which is composed of a nanoscale photo-electric device having two energy levels in contact with two electron reservoir leads at the same temperature but with different chemical potentials whose task is to convert radiation energy to electric energy. We analytically study the optimized thermodynamic efficiency, which lies between Carnot efficiency and efficiency at maximum power, of our model displaying strong coupling between the generated electron flux and the incoming photon flux from the sun. We also find the time taken to accomplish one complete cycle at the maximum power and at optimized efficiencies.
