True nature of the Curzon-Ahlborn efficiency
Yann Apertet, Henni Ouerdane, Christophe Goupil +1
The Curzon-Ahlborn efficiency has long served as the definite upper bound for the thermal efficiency at maximum output power, and has thus shaped the development of finite-time the…
The thermoelectric working fluid: thermodynamics and transport
G. Benenti, H. Ouerdane, C. Goupil
Thermoelectric devices are heat engines, which operate as generators or refrigerators using the conduction electrons as a working fluid. The thermoelectric heat-to-work conversion…
A note on the electrochemical nature of the thermoelectric power
Y. Apertet, H. Ouerdane, C. Goupil +1
While thermoelectric transport theory is well established and widely applied, there remains some degree of confusion on the proper thermodynamic definition of the Seebeck coefficie…
Influence of thermal environment on optimal working conditions of thermoelectric generators
Y. Apertet, H. Ouerdane, C. Goupil +1
Optimization analyses of thermoelectric generators operation is of importance both for practical applications and theoretical considerations. Depending on the desired goal, two dif…
Comment on "Heat dissipation in atomic-scale junctions"
Y. Apertet, H. Ouerdane, C. Goupil +1
We discuss the recent results of Lee et al. [Nature 498, 209 (2013)] using the notion of thermoelectric convection. In particular, we highlight the fact that this contribution to t…
A linear nonequilibrium thermodynamics approach to optimization of thermoelectric devices
H. Ouerdane, C. Goupil, Y. Apertet +2
Improvement of thermoelectric systems in terms of performance and range of applications relies on progress in materials science and optimization of device operation. In this chapte…

Y. Apertet, H. Ouerdane, C. Goupil +1
In a recent article, Baranowski et al. [J. Appl. Phys. 113, 204904 (2013)] proposed a model that allegedly facilitates optimization of thermoelectric generators operation as these…
On the efficiency at maximum cooling power
Yann Apertet, Henni Ouerdane, Aurelie Michot +2
The efficiency at maximum power (EMP) of heat engines operating as generators is one corner stone of finite-time thermodynamics, the Curzon-Ahlborn efficiency being co…
From local force-flux relationships to internal dissipations and their impact on heat engine performance: The illustrative case of a thermoelectric generator
Yann Apertet, Henni Ouerdane, Christophe Goupil +1
We present an in-depth analysis of the sometimes understated role of the principle of energy conservation in linear irreversible thermodynamics. Our case study is that of a thermoe…
Reply to the Comment on "Optimal working conditions for thermoelectric generators with realistic thermal coupling" by S. Su et al
Y. Apertet, H. Ouerdane, O. Glavatskaya +2
We reply to the comment made by Su et al. on "Optimal working conditions for thermoelectric generators with realistic thermal coupling". In particular we justify the efficiency def…
Equivalent parameters for series thermoelectrics
Y. Apertet, H. Ouerdane, C. Goupil +1
We study the physical processes at work at the interface of two thermoelectric generators (TEGs) thermally and electrically connected in series. We show and explain how these proce…
Internal convection in thermoelectric generator models
Y. Apertet, H. Ouerdane, C. Goupil +1
Coupling between heat and electrical currents is at the heart of thermoelectric processes. From a thermal viewpoint this may be seen as an additional thermal flux linked to the app…
