High power thermophotovoltaics and thermophotonics

Achieving high power density is just as crucial as attaining high energy conversion efficiency in thermophotovoltaics and related thermophotonics. In this talk, I will present recent advancements in utilizing novel concepts in both the far-field and near-field regimes to enhance optical thermal power conversion to electricity. Particular emphasis will be placed on a recently demonstrated zero-gap TPV system, along with an exploration of its theoretical potential across various thermal energy conversion applications.
