Nextreme Gets Patent for New High-Temp Solar TE Generator
Durham, NC — Nextreme Thermal Solutions has been awarded a U.S. patent for the design of an innovative solar thermoelectric generator (solar TEG) for high-temperature solar thermoelectric energy conversion. Patent #7,638,705 — "Thermoelectric Generators for Solar Conversion and Related Systems and Methods" — describes a method of using thermoelectric generators in combination with thermally conductive plates to generate power in response to solar radiation. Thermoelectric devices generate electricity via the Seebeck Effect, where voltage is produced from a temperature differential applied across the device.

High-temperature solar thermal systems that incorporate solar concentrators can operate between 600 and 700°C. At those temperatures, a multi-stage cascade thermoelectric power generator may provide a design efficiency of well over 15 percent. Design efficiencies in this range permits flexibility and adaptability to new and cost-effective real-world solar thermal systems. The invention was developed in collaboration with Dr. Rama Venkatasubramanian, director of the Center for Solid State Energetics at RTI International in Research Triangle Park, North Carolina. The company is seeking commercial partners to further develop the technology for large scale solar thermal energy harvesting solutions.
