Our results indicate that a well-designed simple post-processing process can boost the efficiency of thermoelectric power generators made of conjugated polymer thin films.
This paper describes a sequential doping/dedoping method for the enhancement of thermoelectric properties of organic semiconductor that also permits the fabrication of transparent and flexible thermoelectric nanofilms. This method allows a precise control of oxidation level without deterioration of the film surface defects.
The thermoelectric performance of poly(3,4-ethylenedioxythiophene) complexed with a poly(4-styrenesulfonic acid) (PEDOT:PSS) film was enhanced by a three-step process.
