Abstract

A PEDOT:PSS film having enhanced thermoelectric properties is doped with DMSO and a binary secondary dopant, such as PEO. The composition of such film causes the ratios of PEDOT in bipolaron states to be increased. As a result, the Seebeck coefficient, the electrical conductivities, and power factor of the film are increased, thereby increasing the efficiency of the film. Thus, a thermoelectric device that uses the film is able to achieve enhanced operating performance.
