Organic and hybrid organic-inorganic semiconductors are highly interesting emerging materials as their opto-electronic properties can be easily tailored to the desired application. They are able to convert light into electricity, or electricity into light. These properties enable the use of these materials in devices like photovoltaic cells, optical sensors for the visible to short-wave infrared range, and organic light-emitting devices (OLEDs). We conduct both fundamental research, on understanding the principles behind these properties, and applied research for integration of new materials in specific devices, hereby pursuing structure-property relations and rational design of new materials. We have a longstanding tradition in joint scientific R&D within European, national, and regional projects, as well as servicing for industry and research centers.
