Thermodynamic energy conversion efficiencies

Journal of Applied Physics, 1980
Much recent work on thermodynamic energy conversion efficiencies is here presented ab initio and from a unified point of view. New considerations are offered and previous work is analyzed in light of the unified presentation. The energy conversion processes discussed include, for example, the conversion into light in a laser or light-emitting diode and

Energy Conversion Efficiency in Nanotube Optoelectronics

Nano Letters, 2005
We present theoretical performance estimates for nanotube optoelectronic devices under bias. Current-voltage characteristics of illuminated nanotube p-n junctions are calculated using a self-consistent nonequilibrium Green's function approach. Energy conversion rates reaching tens of percent are predicted for incident photon energies near the band gap ...

Energy Conversion Efficiencies

2012
Efficiency is a measure of the true effectiveness or performance of a system or a process. It may take different forms but it can generally be defined as the desired output over the required input. Energy conversion efficiency refers to an efficiency definition for a device for which one form of energy is converted to another form.
