Design and thermal modeling of a portable fuel fired cylindrical TPV Battery Replacement
ABSTRACT: A novel portable fliel fired cylindrical themiophotovoltaic batteiy charger is described. It uses an array of GaSb TPV cells along with a novel Omega recuperator design and a novel IR emitter design. Computational fluid dynamic (CFD) calculations are presented for this TPV cylinder design showing the potential for an overall fuel to electricity conversion efficiency of 10.9%. The ...

TPV History from 1990 to Present & Future Trends
Abstract. Herein, the history of TPV at JX Crystals over the last 15 years is described. Our focus has been on commercial application for TPV components and systems. JX Crystals began as a spin off company when the inventors of the GaSb cell left Boeing with a license to make that cell at JX Crystals. We recosnized that III-V IR sensitive cells such as the GaSb cell were enabling for TPV systems. ...

Economic Potential for Thermophotovoltaic Electric Power Generation in the Steel Industry
ABSTRACT - A steel mill extrudes steel billets at temperatures above 1400 °C continuously 24 hours a day. The steel billets then go to cooling beds where they slowly cool down to below 1100 °C. JX Crystals Inc makes Gallium Antimonide (GaSb) thermophotoyoltaic (TPV) cells that can generate over 1 W/cm when exposed to infrared radiant energy from glowing steel at temperatures above 1100 ...

Adapting TPV for Use in a Standard Home Heating Furnace
Abstract, A novel TPV configuration will be presented that can fit into a standard home furnace cabinet. This system incorporates an externally faceted glass cylinder with a dichroic filter deposited on its outer surface and a GaSb IR cell array bonded to the outer surface on top of the filter. This cylindrical array is then surrounded with an envelope containing a low boiling point liquid for ...

Design of a Matched IR Emitter for a Portable propane fired TPV Power System
ABSTRACT: The design of an IR emitter is described for use with a small portable cylindrical ThermoPhotoVoltaic (TPV) generator. The IR emitter consists of a cylindrical array of 1 to 2 mm diameter ceramic rods. The spacing between these rods is chosen such that slits are formed between the rods with a slit width equal to about 1/10* of the rod diameter. Computational Fluid Dynamic (CFD) modeling ...
