Flexibility investigations on low-temperature processed nanostructured polymer/titania hybrid films — •Tobias Widmann, Weijia Wang, Lin Song, and Peter Müller Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, James-Franck-Str. 1, 85748 Garching

On the way to green energy, hybrid solar cells show great potential. They combine a conducting polymer with an inorganic semiconductor and therefore have advantages of both materials. The flexibility is one of the most promising properties of hybrid solar cells, which ensures the production by a roll-to-roll process and in large scale. Hence, in this work the flexibility of low temperature processed hybrid thin films is investigated. A porous film structure is synthesized by incorporating a titania precursor into a diblock copolymer which functions as the template. Thereafter it is deposited on a flexible substrate and a bending test is implemented by a custom made machine. The alteration of the bare titania structure and the hybrid film structure due to bending is investigated with optical microscopy and SEM and correlated with photophysical properties probed with UVvis and PL.
