Abstract
New GaSb photovoltaic cells with infrared response extended out to
1.8 microns are well matched to hydrocarbon combustion heated silicon
carbide infrared emitters operating at 1500 C. These continuous
combustion thermophotovoltaic units run quietly and cleanly.
Applications include small scale distributed cogeneration of heat and
electricity and power units for clean electric vehicles. We report the
fabrication of 1 cm2 GaSb cells operating at 6 Amps and 2.6
Watts, 10 cell circuits operating at over 22 Watts, and a small
demonstration generator producing enough power to operate a television
