Enhanced thermoelectric figure of merit and heat-electricity efficiency in p-type Mm<sub>0.8</sub>Fe<sub>2.7</sub>Co<sub>1.3</sub>Sb<sub>12</sub> skutterudites <i>via</i> polyaniline compositing
The lattice thermal conductivity of p-type skutterudite Mm<sub>0.8</sub>Fe<sub>2.7</sub>Co<sub>1.3</sub>Sb<sub>12</sub> is reduced to ∼0.69 W m<sup>-1</sup> K<sup>-1</sup> at 623 K <i>via</i> compositing 0.75 wt% polyaniline nanoparticles. The thermoelectric figure of merit reaches ∼1.16 at 723 K, and the efficiency of a virtual device gets to 10.7% at Δ<i>T</i> = 480 K through finite element simulations.
