Abstract
A thermophotovoltaic generator provides a greater power output while maintaining a compact, simplistic structure. The generator includes a burner having adjustable fuel and air flows, an infrared radiation emitter suspended above the flame nozzle of the burner and a cylindrical receiver surrounding the emitter. The emitter is a conical infrared emitter connected to the burner by wires. The emitter is positioned above the burner nozzle such that the emitter is immersed in the generated hydrocarbon flame. The emitter material catalyzes combustion on its surface. Infrared energy radiated by the heated emitter is collected by a cylindrical receiver that completely encircles the emitter. The receiver includes a flexible circuit having an inner surface, an outer surface, opposite ends, top and bottom edges and bending regions. First and second rows of low bandgap cells are connected to the top and bottom edges of the circuit, respectively, away from the bending regions. Copper contact pads are placed on the top cell bonding side of the circuit. A thin, polyimide insulating layer is placed over the outer surface of the circuit and the contact pads, and a thin metal sheet is located under …
