Direct conversion of heat to electricity via solid-state approaches is a rapidly advancing area
of research owing to its prospective use in recovering waste heat and in energy storage and …

Power can be generated from radiative exchange between two bodies with different
temperatures—from the radiative cooling of the Earth's surface into space, for example …

Thermophotovoltaic approaches that take advantage of near-field evanescent modes are
being actively explored due to their potential for high-power density and high-efficiency …

Right after the first edition was published in 2007, I was invited to give seminars at a number
of universities in several countries. At that time, many people considered nanotechnology …

The US industries reject nearly 20–50% of the consumed energy into the environment as
waste heat. Harvesting this huge amount of heat can substantially improve the energy usage …

The sun and outer space are two of the most important fundamental thermodynamic
resources for renewable energy harvesting. A significant amount of work has focused on …

We derive the thermodynamic limits of harvesting power from the outgoing thermal radiation
from the ambient to the cold outer space. The derivations are based on a duality relation …

Photovoltaics possess significant potential due to the abundance of solar power incident on
earth; however, they can only generate electricity during daylight hours. In order to produce …

Radiative thermoelectric energy converters, which include thermophotovoltaic cells,
thermoradiative cells, electroluminescent refrigerators, and negative electroluminescent …

Theromoradiative (TR) devices, though proposed a decade ago, have seen little
investigation due to their low-performance compared to other solid-state energy conversion …
