Thermoelectric properties of flexible PEDOT:PSS-based films tuned by SnSe via the vacuum filtration method.

ABSTRACT: In this study, flexible thermoelectric tin selenide (SnSe)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composite films have been fabricated by the vacuum filtration method, and their thermoelectric properties were investigated. The electrical conductivities of the composite films have a tendency to decrease with an increase in the SnSe content, while their Seebeck coefficients have an inverse tendency. The electrical conductivities decrease gradually with an increase in temperature, while the Seebeck coefficients show a tendency to increase first and then decrease with the increase in temperature. The maximum power factor (PF = S ² σ) of the composite film is obtained when the SnSe content is 10 wt%, which is 24.42 μW m^-1 K^-2
