Universality of efficiency at maximum power: Macroscopic manifestation of microscopic constraints

Universal properties of efficiency at maximum power are investigated in a general setting. In particular, it is demonstrated how successive symmetries placed upon the dynamics manifest themselves at the macroscopic level. A general condition is derived for which thermodynamic devices are able to attain a reversible operation.

Reaching optimal efficiencies using nano-sized photo-electric devices

We study the thermodynamic efficiency of a nano-sized photo-electric device and show that at maximum power output, the efficiency is bounded from above by a result closely related to the Curzon-Ahlborn efficiency. We find that this upper bound can be attained in nano-sized devices displaying strong coupling between the generated electron flux and the incoming photon flux from the sun.
