Thin P3HT:PCBM films with embedded magnetic nanoparticles — •Florian Dreher, Daniel Moseguí González, and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching, Germany

Among the different photoactive systems studied in organic solar cells, the combination of P3HT:PCBM has been most prominent due to easy chemical synthesis and, thus, commercial availability. In order to further increase the device performance, doping with magnetic nanoparticles had shown interesting behavior as the device efficiency can be increase upon nanoparticle addition.[1] In the present study we focus on thin P3HT:PCBM films and investigate the impact of different concentrations of magnetic nanoparticles under various processing conditions. The film morphology is probed with SEM, AFM and scattering techniques. UVvis spectroscopy and photoluminesces measurements complement these morphology studies. In combination with device characterization we gain a structure-function relationship for these thin hybrid films.
