Abstract
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 TaSi,emitter layers and 0.14 micron ZrO,or Al,O,antireflection layers used as IR emitters for GaSb converter cells in TPV generators.
