Molecular doping is a powerful technique that can easily control the optoelectronic properties of conjugated polymers. In particular, for organic thermoelectrics application it is essential to develop highly doped conjugated polymers with sufficiently high electrical conductivity. However, in the highly doped state, the film structure and charge transport properties are greatly changed compared to the undoped state by the dopant mixed in excess; thus, a deep understanding of molecular doping of conjugated polymers is essential to increase thermoelectric performance and further reach a commercialization. In this talk, engineering strategies for obtaining excellent charge transport properties in highly doped conjugated polymers will be discussed. In particular, the effects of intermolecular Coulombic interactions, energetic disorder, film structure and molecular ordering on the charge transport properties will be discussed.
