Thermoelectric Energy Conversion: Transport, Materials, and Systems
05 Dec 2012 | Online Presentations | Contributor(s): Gang Chen
his talk will start with an introduction to thermoelectric effects, and move on to discuss ways to understand and engineer electron and phonon transport in thermoelectric materials to improve the figure of merit. On phonon transport, thermal conductivity spectroscopy and coherent heat conduction will be discussed. Modulation doping in 3D random structures and invisibility of nanoparticles to electron transport will be explored for improving the electron performance. Device and system challenges will be discussed, with a focus on solar thermoelectric energy conversion, including the demonstration of flat-panel solar thermoelectric generators at 4.6% efficiency with no optical concentration.
