The potential market for Thermo-Electric technology is 56 billion, with 26bn for transportation cooling alone.Current commercial Thermo-Electrics for cooling applications are typically based on Bismuth Telluride (Bi2Te3)where the Figure of Merit, ZT peak is 1.0 @ 80oC and average ZT over Thermo-Electric Cooling (TEC) operatingtemperature of 0.8, limiting the maximum heat flow (Qmax) to 52.2W, the maximum temperature difference(Tmax) to 74oC and the Coefficient of Performance (CoP) of 1.46 for a typical TEC module.HUNTER will develop advanced materials solutions based on Phonon scattering through grain boundaryengineering; Engineering of antisites and Metal-semiconductor interface for electron filtering to create n- andp-type Thermo-Electric BiTe alloys with average ZT1 across the effective operating temperature range. Byachieving this performance, we will be able to increase TEC module efficiency so that Qmax > 57.3W, Tmax>78oC and CoP 1.94, this is beyond anything achieved previously. By achieving this we will create global USPsfor TEC modules with particular application for automotive zonal cooling applications. Project Summary
