Fabrication and characterisation of a flexible thermoelectric generator using PANI/graphite/bismuth telluride composites.

ABSTRACT: Unique thermoelectric properties of low-cost, widely available conducting polymers and multi-layered graphite structures have motivated the development of flexible thermoelectric generators using screen printing for low-temperature applications. Composites of polyaniline and graphite in different ratios with one weight percentage of bismuth telluride were prepared to fabricate flexible thermoelectric generators. The performance of the devices showed that the addition of graphite to polyaniline reduced the band gap energy from 2.90 to 1.33 eV, which was further reduced to 1.05 eV upon the addition of bismuth telluride. Adding graphite and bismuth telluride to polyaniline increased carrier mobility from 0.12 to 0.41 cm² V^-1 s^-1 without affecting carrier conce
