Abstract

Thermoelectric (TE) generators/refrigerators have the advantages of lack of moving parts, quiet operation, and flexibility in deployment, but their use has been limited because of their relatively low conversion efficiency. Two major loss components are conductive (phonon) heat transfer through the TE lattice and parasitic losses at fabrication interfaces. Shock wave consolidation of thermoelectric nanopowders to produce TE devices will reduce both loss sources, leading to enhanced efficiency devices.
