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.

Nextreme said it is seeking commercial partners to further develop the technology for large scale solar thermal energy harvesting solutions.
