Abstract Recent developments in iontronic materials and devices highlight the importance of efficient ion conduction optimizing their performance. In particular, improving transport polymer electrolytes is key to progress advanced energy conversion systems. This study presents a novel approach enhance conductivity poly(ethylene oxide) (PEO)–NaOH within porous polydimethylsiloxane (PDMS) composites. By coating PDMS with thin layer polydopamine (PDA) filling it PEO–NaOH, numerous hopping sites are generated at PEO‐PDA interface for Na + transport, thereby conductivity. Additionally, by combining broadband absorption PDA scattering properties PDMS, ability PDA–PDMS composite efficiently absorb convert solar radiation into heat demonstrated. The confined light‐exposed region due thermal insulation provided PDMS. confinement creates temperature gradient across composite, preferentially enhancing diffusion cations over OH − anions generate thermoelectric voltage. unique property allows direct electrical energy, offering new possibilities sustainable technologies.
