This article reviews the state of the art and historical development of thermophotovoltaic
(TPV) energy conversion along with that of the main competing technologies, ie Stirling …

Solid-state heat-to-electrical power converters are thermodynamic engines that use
fundamental particles, such as electrons or photons, as working fluids. Virtually all …

By exploring a semi-empirical model, the saturation current density J 0 is identified to
manifest the significant difference in carrier lifetime between interband cascade devices …

Research activities and progress in narrow bandgap (< 0.5 eV) photovoltaic (PV) cells for
applications in thermophotovoltaic (TPV) systems are reviewed and discussed. The device …

We report on the characterization of narrow-bandgap (E g≈ 0.4 eV, at 300 K) interband
cascade thermophotovoltaic (TPV) devices with InAs/GaSb/AlSb type-II superlattice …

Graphene-based photodetectors have drawn a large amount of interests owing to its wide
spectral response, however, the high dark current greatly limits their applications. In this …

This paper describes microscopic calculations of photocurrent generation spectra due to
intersubband transitions in semiconductor heterostructures that can extract energy from …

We demonstrate the first low bandgap thermophotovoltaic (TPV) arrays capable of operating
with heat sources at temperatures as low as 345° C, which is the lowest ever reported. The …

Quantum cascade (QC) detectors in the GaN/Al x Ga 1− x N material system grown by metal
organic chemical vapor deposition are designed, fabricated, and characterized. Only two …

This work addresses the question of how much electrical power can in principle be extracted
from heat radiation via the combined use of interband and intersubband photodetection as a …
