Poly(3-hexylthiophen-2,5-diyl) (P3HT) is one of the most prominent semiconducting, conjugated polymers in the fields of organic electronics and photovoltaics. Upon addition of a suitable metal dopant, e.g. chloroauric acid (HAuCl4), thin P3HT films exhibit thermoelectric properties with large values for the power factor and figure of merit. To investigate the possibility and efficiency of future scalable industrial manufacturing, spin-casted and spray-deposited P3HT films were compared correlating their structural differences with their thermoelectric performance upon doping using AFM, GISAXS/GIWAXS, XRR and NR measurements.
