Thermal operating window for PEDOT:PSS films and its related thermoelectric properties
Abstract
The intrinsically conducting polymer PEDOT:PSS is widely used and hasfound high recognition due to its excellent electrical conductivity. Itspotential applications cover many fields, e.g. thermoelectric energyconversion. Therefore we compared the thermoelectric propertiesofpristine and DMSO treated PEDOT:PSS films at potential operatingtemperatures. Here we observed the electrical degradation of the film upto complete failure. Further, the thermal aging of PEDOT:PSS stilllacks of understanding. It is pointed out that PEDOT:PSS films show acomplex degradation mechanism which includes a morphological and achemical part. In the range of room temperature and ∼160 °C PEDOT:PSSfilms follow the known exponential degradation which imposesmorphological degradation, while at higher temperatures this law is notsuitable to match the experimental data. Thus we extended the knownexponential equation by an additional exponential degradation term whichshows good agreement with the experimental data. The optical absorptionspectrum indicates a loss in bipolaron and polaron charge carriers,which reflects the degradation behavior. It can be seen that changes inthe optical absorption spectrum after isothermal annealing for more than50 h occur at temperatures around 120 °C, which marks the transitionfrom morphological to chemical degradation.
