In this study, we synthesized nanoparticles (NPs) in an aqueous solution and investigated the thermoelectric characteristics of NPs thin films on plastic substrates. Regardless of thermal annealing treatment, all the NPs thin films show the negative Seebeck coefficients, indicating the n-type characteristics. As the annealing temperature increases, the electric conductivity increases while the Seebeck coefficient decreases. The electric conductivity of the thin film annealed at is larger by times, compared with the as-prepared thin film, And the maximum power density for the thin film annealed at is calculated to be .
