Enhanced Thermoelectric Properties Of Skutterudite Thick Film Polyvinyl Alcohol Assisted From The Post-Deposition Annealing Effect

Thick film has demonstrated a high Seebeck coefficient, S, for thermoelectric material but it is very challenging to obtain through cost-effective techniques. Electrodeposition is adopted to tailor the film's thickness, t, facilitated by additive and heat treatment to boost the S. Here, we repo...

description Thick film has demonstrated a high Seebeck coefficient, S, for thermoelectric material but it is very challenging to obtain through cost-effective techniques. Electrodeposition is adopted to tailor the film's thickness, t, facilitated by additive and heat treatment to boost the S.

The films are synthesized at room temperature via chronoamperometry from an aqueous electrolyte consisting of cobalt and antimony ions assisted with PVA (1800 and 98 000 Da).
