Abstract

In a semiconductor light emitting device such as an LED, when a voltage is applied to increase the chemical potential of photons, a thermodynamically nonequilibrium state is generated, and light emission may be different from Planck's law black body radiation. In this study, we focus on Thermophotonic power generation system composed of LED and PV cell, and discuss the mechanism of non-equilibrium thermal radiation via fluctuational electromagnetic simulation.
