In situ polymerization of organic conductive thin films — •Jenny Lebert and Eva M. Herzig — TU München, Munich School of Engineering, Lichtenbergstr. 4, 85748 Garching

Organic semiconducting materials can be applied in optoelectronic devices such as organic light-emitting diodes and organic solar cells. The conductivity and optoelectronic properties of polymers strongly depend on their molecular morphology and crystallization behavior. Therefore controlling the thin film morphology is one of the main challenges when it comes to developing fabrication processes that work in small labs as well as in large industrial scales. Moreover, a profitable scale-up requires the use of low-priced and available materials.

In situ polymerization of the active material is a promising approach for the fabrication of conductive thin films, as it combines the use of cheap materials with the possibility to control the film morphology. In this work, different synthetic chemical routines are combined with systematic physical analyses to investigate varying systems. The obtained polymer films are analyzed regarding their optic and optoelectronic properties, their conductivity and morphology. Additionally they are employed as active layers in organic solar cells.
