Abstract

Polythiophene films were fabricated by electrolytic polymerization. We have evaluated thermoelectric properties of Seebeck coefficient, electrical conductivity, hall mobility and career concentration of the films in the in-plane direction. The Seebeck coefficient of polythiophene was larger than other conductive polymers. Electrical conductivity was strongly dependent on hall mobility. High conductivity was due to smooth surfaces, high compactness, and high crystallinity. To improve the figure of merit, it is important to increase not only the career concentration but also the mobility.
