| 제목 | High enhancement in Thermoelectric Performance of PEDOT:PSS Thin Film byIncorporation of Small Amount of Graphene |
| 초록 | Graphene (1～3wt%) incorporated PEDOT:PSS thermoelectric thin films were prepared through a solution method with a spin coater. The thermoelectric thin films with graphene (1～3wt%) have higher values than PEDOT:PSS for the electrical conductivity, the power factor, and ZT because of graphene’s enhanced carrier mobility (40,000 cm2V-1s-1 at 300K). The electrical conductivity of PEDOT:PSS with 2wt% graphene in this experiment was 32.13 S/cm and the power factor was 11.09 W/mK without a reduction in the Seebeck coefficient. The ZT of PEDOT:PSS with 2wt% graphene was estimated to be about 0.024 at 300K, which is higher than the corresponding value for PEDOT:PSS (ZT=10-2 to 10-3) and bulk Si (ZT=0.01). |
