In this study, we examine the effects of disorder on the TE properties of semiconducting polymers based on the Gaussian disorder model for site energies. We show that stronger overlap between sites can improve the electrical conductivity without adversely affecting the Seebeck coefficient.
Schematic representation of the carrier hopping process, showing overlap, energetic, and positional disorder.
