Abstract

In this work, we fabricate a novel type of thermoelectric composite by mixing high-mobility poly(3,4-ethylene dioxythiophene), P3HT with tellurium nanowires (TeNW) and newly synthesized three different (S2-, SET and SPh) sulfur-contained tellurium nanowires. The advantage of the presence of sulfur in the hybrid film is to prevent aggregation and the ability to dissolve in polar solvents. The thermoelectric properties are investigated by varying the loading of tellurium nanowires into the polymer matrix. The spin coating method is used to fabricate the thermoelectric devices on Quartz substrates. We achieved a maximum power of 47.7μW/mk2, the highest reported for tellurium/P3HT nanowire composites. The results of this study also indicate that the doping of P3HT increases the thermoelectric properties of hybrid composites. The thickness of the hybrid thin films was investigated using SEM images.
