Problems solved by technology

Although the use of micron and submicron gaps between the hot-side emitter and cold-side collector allows power densities to be increased by more than an order of magnitude over most conventional thermoelectric devices, due to the absorption of out-of-band thermal radiation by the cold-side collector, cold The temperature of the side collector will also increase accordingly

Abstract

A method and device for maintaining a low temperature of a cold-side emitter for improving the efficiency of a sub-micron gap thermophotovoltaic cell structure. A thermophotovoltaic cell structure may comprise multiple layers compressed together by a force mechanism so that the sub-micron gap dimension is relatively constant although the layer boundaries may not be substantially flat compared to the relatively constant sub-micron dimension. The layered structure includes a hot side thermal emitter having a surface separated from a photovoltaic cell surface by a sub-micron gap having a dimension maintained by spacers. The surface of the photovoltaic cell opposite the sub-micron gap is compressibly positioned against a surface of microchannel heat sink and the surface of the microchannel heat sink opposite the photovoltaic cell is compressibly positioned against a flat metal plate layer and a compressible layer.

Description

Background technique [0001] The present invention relates to micro-gap thermophotovoltaic (MTPV) technology for converting radiant thermal power into electricity. Although the use of micron and submicron gaps between the hot-side emitter and cold-side collector allows power densities to be increased by more than an order of magnitude over most conventional thermoelectric devices, due to the absorption of out-of-band thermal radiation by the cold-side collector, cold The temperature of the side collector will also increase accordingly. In order to maintain the efficiency of the cold side collector and to maintain a consistent gap distance between the hot side emitter and cold side collector, various means have been employed to keep the cold side collector at a reduced temperature. The present invention more particularly relates to a new method and apparatus for maintaining a relatively low temperature of the cold side collector by using a microchannel heat sink employing a liq...
