Nanostructure-Enhanced Bulk Thermoelectric Materials
Agency / Branch:
DOD / OSD
The use of thermoelectric devices as alternative energy sources has been investigated with limited success. Manufacturing costs and limited power generation efficiency have prevented the economical, large-scale production and use of the thermoelectric devices as a viable alternative energy source. Agiltron has proposed an innovative nanostructure-enhanced thermoelectric material that will integrate the synthesis of PbSe nanowires and the fabrication of nanocomposite-enhanced bulk thermoelectric materials. The proposed technologies will include single-phase, highly-crystalline, surface-clean and diameter-controlled PbSe nanowires fabrication; orientation, and densification with ball-milled submicrometer-sized powder of bulk thermoelectric material into nanocomposite-enhanced thermoelectric material through a hotpress technique. The thermoelectric figure of merit of this new nano-composite is predicted to reach ZT = 3 at 300K. This innovative thermoelectric material will have immense application potentials in power generation, energy harvesting, and solid-state cooling and refrigeration.
