| 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°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°C is calculated to be 44μW/cm^2. |
