Abstract

In this study, we synthesized $Ag_2Se$ nanoparticles (NPs) in an aqueous solution and investigated the thermoelectric characteristics of $Ag_2Se$ NPs thin films on plastic substrates. Regardless of thermal annealing treatment, all the $Ag_2Se$ 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 $180^{\circ}C$ is larger by $10^6$ times, compared with the as-prepared thin film, And the maximum power density for the thin film annealed at $180^{\circ}C$ is calculated to be $44{\mu}W/cm^2$.
