Let's celebrate the scientific spirit with joy and sense of humor together!

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.

He is the sole member awarded this title for 2019.
