Structure and performance of water soluble solar cells functionalized with non-magnetic nanoparticles — •Nuri Hohn, Daniel Moseguí González, and Peter Müller Buschbaum — TU München, Physik Department, LS Funktionelle Materialien, James-Franck-Str. 1, 85748 Garching

Organic solar cells (OSCs) offer a great potential due to low cost, large scale production and flexible design. For preparation of OSCs the hole conducting polymer Poly[3-(potassium-6-hexanoate)thiophene- 2,5-diyl] (P3P6T) is employed. For comparability reasons with the broadly studied P3HT:PCBM system, P3P6T is combined with an also water-soluble C60 fullerene derivative. With respect to environment protection, the manufacturing process of the active layer tends towards a more friendly approach compared to common OSCs based on harmful organic solvents. Additionally, inclusion of non-magnetic nanoparticles in the above mentioned system is carried out, which is found to have a strong impact on the efficiency of organic, electronic devices. We pursue to characterize the influence of these nanoparticles on the rate of intersystem crossing, as this effect eventually leads to extended exciton lifetimes. Primary investigations address the electrical, spectral and morphological characterization.
