Abstract

We will talk about our recent experiments of near-field based energy applications. First, we will show a 40-fold enhancement of thermophotovoltaic electricity generation rates by maintaining a nanoscale gap between a thermal emitter and a photovoltaic cell. Secondly, we will show the realization of photonic refrigeration by controlling the chemical potential of photons. We achieved net cooling on a planar device by suppression of radiation from a reverse-biased photodiode, and enhancement of photon transfer from the planar device.
