| Abstract Scope |
This lecture presents the global energy challenges and Chinese strategy, the research activities and main progress on thermoelectric (TE) materials and recent development of TE applications in China. As a leading TE research group in China, we have recently made four important progresses as followings: (1) having discovered the multi-local effects coexistence mechanism of electric and thermal transport on the atomic and molecular scale and the superparamagnetic enhancement of thermoelectric performance; (2) having explored a novel self-propagating high-temperature synthesis technology that can realize the large-scale ultra-fast preparation of high-performance TE materials in less one minute; (3) having developed the solar energy photovoltaic(PV)-TE hybrid power generation technology that have been applied to have built two solar power generation demonstration systems with 5kW and 100kW; (4) having built an automotive waste heat TE power generation demonstration vehicle that can recover about 1000W electrical energy from the automotive exhaust. |
