This article covers a study on the significant enhancement of thermoelectric performance in PEDOT:PSS films doped with DAE, through manipulation of polaron interfacial entropy. By using UV light to induce resonance between PEDOT and diarylethene, researchers achieved a tenfold increase in thermopower without compromising electrical conductivity. This method provides a novel approach to improving the efficiency of organic thermoelectric materials, offering insights into decoupling thermopower and electrical conductivity in such films.
