Control of thermal emission for thermophotovoltaic systems

Thermal emitters play a key role in controlling the thermal radiation emitted thermophotovoltaic systems and increasing their energy conversion efficiency. Here, we present different designs of with spectrally selective properties, based on easy-to-fabricate multilayer structures characterized by sharp transition from high to low emissivity region interest. Those make use refractory materials allow working at operating temperatures they can be easily customized maximize emission desired wavelengths.
