Abstract: Organic-inorganic hybrids are a class of functional materials that combine favorable properties of its constituents to achieve an overall improved performance for a widerange of applications. This article presents the synthesis route for P3HT-porous silicon hybrids for thermoelectric applications. The conjugated polymer P3HT is incorpo-rated into the porous silicon matrix by means of melt infiltration. Gravimetry, sorption isotherms and energy dispersive X-ray spectroscopy (EDX) mapping indicate that theorganic 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 FeCl3solution increases the electrical conductivity of the hybrid by five orders of magnitude compared to the empty porous silicon host.
