Organic conductive polymers (CPs) are good candidates for thermoelectric (TE) materials due to their low thermal conductivity, lightweight, simple processability, and environmentally-friendly characteristics. Among numerous CPs, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) would be the promising candidate TE material due to its advantages of high electrical conductivity, low thermal conductivity, light-weight, and high flexibility. Nevertheless, CPs-based TE materials still suffer from much lower Seebeck coefficients compared with inorganic TE materials. In this work, we successfully demonstrate that the Seebeck coefficient of PEDOT:PSS is enhanced by controlling the hole carrier concentration of PEDOT:PSS using a self-assembly monolayer (SAM). The power factor of the PEDOT:PSS film is about 3 times enhanced. This work can contribute to fabrication of organic-based flexible and high-performance TE modules.f |
