Paper Abstract

In thermophotonic cooling (TPC) the requirement of efficient photon extraction out of the semiconductor material is removed by the absorption of the light within the semiconductor structure. TPC cooling currently offers one of the most viable approaches to observing electroluminescent cooling of semiconductors in practice. We discuss a detailed numerical model that accounts for the current and photon transport as well as various loss mechanisms like the mirror losses and the nonradiative losses in the structure. The model essentially consists of the semiconductor equations for current transport and the radiative transfer equation for the photon transport.
