Abstract:

Thermoelectrics can directly realize the two-way conversion between electricity and heat and provide a promising approach to solve the global energy crisis. Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is a promising organic thermoelectric material due to its intrinsically low thermal conductivity, high electric conductivity, transparency in the visible and solution processability.

In the present thesis we provide a comprehensive study on the optical and thermoelectric properties of PEDOT:PSS thin films. In particular, we focus on two relevant aspects: (i) the thickness dependent optical and thermal properties of PEDOT:PSS thin films, and (ii) the modification of their optical and thermoelectric properties through mixing with ZnO nanocrystals and graphene quantum dots.
