This article presents the synthesis route for P3HT-porous silicon hybrids for thermoelectric applications. The conjugated polymer P3HT is incorporated into the porous silicon matrix by means of melt infiltration. Gravimetry, sorption isotherms and energy dispersive X-ray spectroscopy (EDX) mapping indicate that the organic molecules occupy more than 50% of the void space in the inorganic host. We demonstrate that subsequent diffusion-based doping of the confined polymer in a FeCl3 solution increases the electrical conductivity of the hybrid by five orders of magnitude compared to the empty porous silicon host.en1387-18112022Elsevierhttps://creativecommons.org/licenses/by/4.0/Melt infiltrationMesoporous siliconOrganic–inorganic hybridP3HTPhysikJournal Article10.15480/882.465410.1016/j.micromeso.2022.11215510.15480/882.4654Journal Article
