Converting thermal radiation into electricity: a milestone is reached

Chapeau

Research teams from CETHIL in Lyon and IES in Montpellier have demonstrated the possibility of converting thermal radiation from a moderate temperature surface (~ 450 °C) into electrical power with an efficiency greater than 10%. By approaching the emitting surface at a short distance from the infrared photovoltaic cell, an electrical power density a thousand times higher than that of previous studies was obtained.

Hybrid thermionic near-field thermophotovoltaic converter

Chapeau
The conversion of thermal energy into electrical energy would make it possible to overcome the problem posed by the intermittency of solar or wind energy. Different paths are currently being studied, and a new concept has just been proposed: a hybrid near-field thermophotovoltaic/thermionic device.
