Near-Field Thermophotovoltaic Conversion with High Electrical Power Density and Efficiency above 14%

Résumé

A huge amount of thermal energy is available close to material surfaces in radiative and nonradiative states, which can be useful for matter characterization or energy harvesting. Even though a full class of novel nano-engineered devices has been predicted over the last two decades for exploiting near-field thermal photons, efficient near-field thermophotovoltaic conversion could not be achieved experimentally until now. Here, we realize a proof of principle by approaching a micron-sized indium antimonide photovoltaic cell at nanometer distances from a hot (~800 K)
