A Novel technique of thermoelectric conversion

The thermoelectric effect is the direct conversion of temperature differences to electric voltage and vice versa. Thermoelectric effects are used in various applications, where heat energy is saved, that would be otherwise lost. Although the TE conversion efficiency is nowadays low (5-8%), the novel technique developed at Weizmann Institute, has a disruptive potential to change this market.  

Prof. Y. Imry and his team at Weizmann Institute came up with Thermal Electric conversion technique, based on a new TE device architecture which allows performance enhancement. The core invention is in the field of Bi-junction thermoelectric device architecture, having a thermoelectric gate interposed between two electric regions, leading to thermal electric conversion efficiency optimization.
