Antireflection coated refractory metal matched emitters for use in thermophotovoltaic generators

Thermophotovoltaic (TPV) electric power generators have emitters with infrared (IR) outputs matched with usable wavelengths for converter cells. The emitters have durable substrates, optional refractory isolating layers, conductive refractory metal or inter-metallic emitter layers, and refractory me...

Zusammenfassung:	Thermophotovoltaic (TPV) electric power generators have emitters with infrared (IR) outputs matched with usable wavelengths for converter cells. The emitters have durable substrates, optional refractory isolating layers, conductive refractory metal or inter-metallic emitter layers, and refractory metal oxide antireflection layers. SiC substrates have tungsten or TaSi2 emitter layers and 0.14 micron HfO2, ZrO2, Al2O3, Ta2O5 and TiO2 antireflection layers used as IR emitters for GaSb converter cells in TPV generators.
