Morphology studies for titania nanoparticle based hybrid solar cells — •Stephan Pröller, Volker Körstgens, and Peter Müller-Buschbaum — TU München, Physik Department, LS Funktionelle Materialien, James-Franck-Str. 1, 85748 Garching, Germany

Thin films containing titania nanoparticles have a variety of applications. For applications in photovoltaics a high absorption coefficient and a large surface area are desirable. Blends of organic and inorganic semiconductors are denoted as hybrid solar cells. Those hybrid solar cells combine the advantages of inorganic semiconductors with the film-forming polymer. Properties of inorganic nanoparticles are size tunability, high absorption coefficients and high mobilities. We use nanoparticles as acceptors in polymer-titania hybrid solar cells. Furthermore, we investigate the influence on the performance of solid-state dye sensitized solar cells based on ruthenium dye and spiro-OMeTAD as hole transport material. The thin films are prepared via spin-coating and solution casting, respectively. The surface structure is investigated with SEM. Thickness and structure of the layer are studied with XRR, the optical properties with UV/Vis spectroscopy and the efficiency of the different solar cells is measured under AM 1.5 conditions.
