Abstract Scope |
Thermoelectric generators (TEGs) utilizing Seebeck effect, which are solid state devices converting thermal energy into electrical energy, are promising solution for waste heat recovery. In order to realize an efficient and reliable TEGs, it is critical that in conjunction with high performance TE materials, there is also a reliable TE module fabrication process. In this presentation, I will discuss the important considerations and techniques that have been successfully applied in reliable and efficient module fabrication, in addition to development of high zT thermoelectric materials. I will discuss the TEG fabrication process that results in low thermal and electrical contact resistances between metal electrodes and TE legs that are compatible to high temperatures. With an optimized device fabrication process and high zT materials, we have demonstrated exceptionally high conversion efficiency of 15 percent in device level. These results are highly promising for advancing the TE modules in waste heat recovery applications. |
