Abstract With the energy crisis and the increasingly severe environmental pollution problems, research for thermoelectric(TE) materials have provoke wide attention in recent years. Among organic TE materials, poly(3,4-ethylenedioxythiophene)∶poly(styrenesulfonate) (PEDOT∶PSS) is considered as the one of the best organic TE materials. It has good film forming properties, high transparency, excellent tunable conductivity and thermal stability. In this paper, various physical and chemical approaches that can effectively improve the electrical conductivity of PEDOT∶PSS are summarized, focusing especially on the mechanism of the conductivity enhancement as well as applications of PEDOT∶PSS flms. It is expected that future research of highly conductive and transparent PEDOT∶PSS films can be developed greatly.
