Abstract

Maximizing the power outputs of devices using benchmark materials is critical for the application of organic thermoelectrics. We report the fabrication of thermoelectric devices using poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) with a Ni foil and polyimide film. The shape of the Ni foil was designed to match the thermal and electrical resistance of the poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) film. Due to the low thermal conductivity of the organic materials, a stable temperature difference of 50 K was achieved under natural cooling conditions without a heat sink at 100 °C. As a result, the device exhibited a power density of 40 μW/cm2, nearly double that of the unoptimized device.
