The invention relates to an organic thermoelectric thin film and a preparation method thereof. The preparation method of the organic thermoelectric thin film comprises the following steps: mixing a solution containing poly(3, 4-ethylenedioxythiophene) and polystyrolsulfon acid with an ionic liquid, after the reaction is finished, transferring the obtained solution into a mold and/or the surface of a substrate, and drying to obtain the organic thermoelectric thin film. By introducing the ionic liquid, the performance of the organic thermoelectric thin film is remarkably improved, the mechanical stretching and bending performance of the organic thermoelectric thin film is improved, and the application range of the organic thermoelectric thin film in the field of organic thermoelectricity and the field of flexible electronics is greatly widened.
