Theory and Performance of Flat Plate Solar Thermoelectric Generator for Near-Earth Orbits

The theory, design, fabrication, and testing of flat plate thermoelectric generator panels for nearearth orbits are described. These panels are capable of producing 3 watts/ft2 and 15 watts/ pound when operating in a near-earth orbit. The potential advantages of these solar energy converters, as compared to photovoltaic cells, are discussed and include higher radiation resistance, improved watts/pound, and lower cost on a perwatt basis.
