Thanks to advances in materials chemistry, researchers have been able to synthesize new materials that allow solution-based processing of next-generation optoelectronic materials

In Printed Electronics, printing technologies are used to produce various kinds of devices, such as electronic circuits, sensors and solar cells. New challenges arise when small scale laboratory processes are transferred to industrially relevant methods.

In the “Functional Thin Film Solution Processing” group, we address scientific and engineering aspects of solution processing, namely

Our coating laboratory provides infrastructure, workforce and knowhow for the deposition of functional coatings and protection layers on rigid and flexible substrates used for the fabrication of optical and electronic devices.

Available equipment at the coating laboratory will enable the development of thin film coating solutions up to DIN A5 scale. The laboratory will evaluate, develop and offer the best-suited technology and analytic for a given functional coating.
