Abstract

In this study, we propose a thermophotovoltaic circular hole pattern Metal-Dielectric-Metal selective emitter. Tungsten and aluminum oxides are used to ensure heat resistance. By analyzing the absorption/ emission characteristics per the change of design parameters, we obtain optimal design values that secure selectively high emissivity. Localized surface plasmon resonance occurs at the edge of the tungsten circular hole pattern in the high absorption/emission band. This resonance has the effect of confining the magnetic field to the dielectric layer by forming induced loop-like currents. The spectral efficiency of the proposed emitter is 41.0％ at 1,000K and 63.7％ at 1,300K. It showed five- and three-times higher efficiency, respectively, than the black-body of the same temperature.
