Organic–inorganic hybrid perovskites have cemented their position as an exceptional class
of optoelectronic materials thanks to record photovoltaic efficiencies of 22.1%, as well as …

The ability to control thermal radiation is of fundamental importance for a wide range of
applications. Nanophotonic structures, where at least one of the structural features are at a …

The currently ubiquitous light-emitting diodes (LEDs) have revolutionized the lighting
industry. Contrary to common belief, however, LEDs are much more than just simple …

Engineering of the cooling mechanism is of primary importance for the development of
nanoelectronics. While radiation cooling is rather inefficient in current electronic devices, the …

We consider near-field heat transfer with nonzero chemical potential for photons, as can
occur between two semiconductor bodies, held at different temperatures with at least one of …

Driven by sub-bandgap electric work and Peltier heat, thermoelectric-driven light-emitting
diodes (TED-LEDs) not only offer much enhanced power-conversion-efficiency but also …

We consider a near-field electroluminescent refrigeration device. The device uses a GaAs
light emitting diode as the cold side, and a Si photovoltaic cell as the hot side. The two sides …

Thermophotovoltaics (TPV) is the direct conversion of radiant heat into electricity through the
photovoltaic effect. TPV is perfectly suited for energy conversion at ultrahigh temperatures of …

We investigate thermoelectric pumping in wide-bandgap GaN based light-emitting diodes
(LEDs) to take advantage of high junction temperature rather than avoiding the problem of …

The possibility of a III-nitride LED with 100% or greater wall-plug efficiency is examined
considering recent observations of the phenomenon for smaller bandgap mid-IR LEDs …
