TL;DR: In this article, a comprehensive and consistent model is formulated to include effects of thermal coupling between the absorbers, space-charge effect, non-radiative recombination, and various irreversible energy losses.

TL;DR: In this article, the authors established a quantum heat engine considering qubits as the external heat transfer medium, and showed that the efficiency and power output of the quantum heat engines are closely dependent on the micro properties of qubits, and consequently relate the irreversible heat transfer with quantum effects.

TL;DR: In this article, a photovoltaic-thermoradiative coupled system is proposed to improve the performance of photovolcanic cells, where the main irreversible losses in the system are considered.

TL;DR: In this paper, a hybrid system consisting of a direct carbon fuel cell and a Gallium antimonide thermoradiative device is proposed, where the effects of thermal coupling between the subsystems, over-potential losses in the fuel cell, non-radiative recombination and sub-bandgap radiation in the thermodynamic device, and various heat losses within the system are included.

TL;DR: An improved nighttime thermoradiative system for electrical power generation by optically coupling Earth's surface with outer space is proposed and it is found that optimizing the thickness of the active layer, enhancing thermal infrared emission, and employing a silver backreflector for photon recycling are crucially important in improving system performance.
