A Carnot Cycle for the Solar Cell

1987
The Carnot cycle of an electron-hole gas, exchanging heat in the form of blackbody radiation with two heat reservoirs, can be easily determined and used to study the thermodynamics of photovoltaic conversion. The thermodynamic efficiency (different from the usual practical efficiency) will be maximum, equal to the Carnot factor, when the evolution of ...

Quantum Equivalent of the Carnot Cycle

Physical Review, 1967
The concept of a quantum heat pump is proposed as a convenient model in the thermodynamic interpretation of certain multilevel processes. The ideal quantum heat engine is defined as an idealization of realistic pumped multilevel systems in much the same way that the well-known Carnot cycle is an idealization of physically realizable, classical ...

Engineering Thermodynamics and the Carnot Cycle

2015
The Carnot cycle is central to engineering thermodynamics and its teaching. Although on the one hand it is an unattainable ideal, on the other it constitutes a set of concepts to which real heat engine cycles and processes should aspire to and approximate. The Two Property Rule means that cycles may be represented graphically and the principal pairs of

Optimization of the direct Carnot cycle

Applied Thermal Engineering, 2007
A model for the study and optimization of two heat reservoirs thermal machines is presented. The mathematical model basically consists of the First and Second Laws of Thermodynamics applied to the cycle and entire system, and the heat transfer equations at the source and sink.

Comments on the closure of the Carnot cycle

Journal of Chemical Education, 1985
Why did Carnot set up the cycle as he did, and didn't his first commentators adopt his procedure?

Carnot cycle for photon gas?

American Journal of Physics, 2001
The Carnot cycle for a photon gas provides a useful means to illustrate the thermodynamic laws. It is particularly useful in showing the path dependence of thermodynamic functions. Thermodynamic relationships to a neutrino gas are also drawn.

The Carnot cycle and Maxwell's relations

Journal of Chemical Education, 1964
Maxwells equations can be derived from nothing more than the Carnot cycle and the deployment of the simplest plane geometry.
