NanoEngineered High ZT Solid State Nanocomposite Thermoelectric (ssnTE) Manufacturing for Multiple Energy Generation Applications
Although thermoelectrics (TE) is a mature technology for the direct conversion of heat into electrical energy, the introduction of nanotechnology has inspired a revolution in capability and applicability. Recent results with nanocomposite films have shown that Figures of Merit (ZT) much greater than 1.0 are now possible, at least at laboratory-scale. These demonstrated results must now be transitioned into commercial applications. This project will optimize and convert high-performance solid state TE materials developed at laboratory-scale into economical products for commercial applications. The approach is to develop a scalable manufacturing process for the large-volume and cost-effective production of nanocomposite TE device films with ZT values exceeding 2.0. Phase I will demonstrate a proof-of-concept scalable manufacturing technology for the nanocomposite films needed for high-performance TE devices. In Phase II, the materials development and device optimization will be continued in a pilot scale tool. Commercial Applications and other Benefits as described by the awardee:Conversion of heat directly to electrical energy will be an important component of many energy generation processes. Thus, devices that recover waste heat from industrial or transportation usages should soon come into great demand. The high volume production of rugged, high-efficiency, and low-cost thermoelectric devices would be a promising candidate for satisfying this demand.
