Fast depleting reserves of conventional energy sources has resulted in an urgent need for
increasing energy conversion efficiencies and recycling of waste heat. One of the potential …

In the last decade Thermo-Photo-Voltaic (TPV) generators have gained an increasing
attention as cogeneration systems for the distributed generation sector. Nevertheless, these …

The advent of negative index materials has spawned extensive research into metamaterials
over the past decade. Metamaterials are attractive not only for their exotic electromagnetic …

In this Letter we demonstrate, for the first time, selective thermal emitters based on
metamaterial perfect absorbers. We experimentally realize a narrow band midinfrared (MIR) …

This study experimentally demonstrates infrared wavelength selective thermal emission
based on Tamm plasmon polaritons (TPPs). Unlike conventional TPP structures, which have …

Recently, there has been increasing interest in utilizing solar thermophotovoltaics (STPV) to
convert sunlight into electricity, given their potential to exceed the Shockley-Queisser limit …

For decades, progress in the field of optical (including solar) energy conversion was
dominated by advances in the conventional concentrating optics and materials design. In …

Applying thermophotovoltaic (TPV) technologies to existing energy generators allows us to
increase energy output while utilizing present infrastructure by reclaiming the heat lost …

Thermophotovoltaics (TPV) was intensively investigated as a technology for heat/electricity
co-generation in the last decade of the 20th century. However, a wide-spread …

Producing high-purity rare earth oxides (REOs) would generate large amounts of industrial
wastes, and as a consequence, the rare earth industry needs to introduce green separation …
