Topic:

Future progress of our information‐based society demands the concentration of optoelectronic functions with increasingly higher capabilities in smaller and smaller volumes. At the same time, steadily increasing mobility of individuals and the need for reliable flow of high volume data calls for light‐weight devices with mechanical flexibility, e.g., in smart clothing. Yet another pressing challenge is the efficient generation of energy from renewable sources, such
as photovoltaics, which needs to become available in the short‐term in substantial quantity. Established materials have been pushed close to their intrinsic limits and many of the devices and systems using these materials are not light weight or bendable (e.g., silicon‐based electronics). Furthermore, the primary energy required for the fabrication of presently established technologies is significant and could be reduced by developing new appropriate materials and production methods. Organic and hybrid organic/inorganic material combinations offer the possibility to overcome some of the current limitations.

The fields of organic electronics and opto‐electronics have seen considerable advances in the past decade, with remarkable progress in light emission or harvesting, flexible electronics and sensors. Some of these applications are already successfully penetrating the market. Hybrid materials for opto‐electronic applications are at a comparably early research stage. Both material classes, organic and hybrid materials, offer the possibility for direct printing from solution, which could enable large‐scale low‐cost fabrication of electronic and opto‐electronic components and devices in a roll‐to‐roll (R2R) fashion. Further progress in this area depends critically on intensive research efforts on organic and hybrid semiconductor materials, with strong focus on material chemistry, electronic structure, mechanical properties, and device integration.
