Making electronics applications more effective, economical and environmentally friendly - this is the aim of the Chemists of the Friedrich-Schiller-University Jena. The team of Prof. Dr. Ulrich S. Schubert, chair of the Laboratory of Organic and Macromolecular Chemistry of the Jena University, now takes place in the newly formed European joint proposal "LOTUS". LOTUS stands for "LOw TemperatUre Sintering" and will be supported for the next three years in the seventh framework programme (FP-7) of the European Union. The total funding is 4 M€, of which the task group of Prof. Schubert will receive 400 k€. In collaboration with 9 other partners from all over Europe, both industrial and academic, the Chemists of Jena University intent to develop a new technology to produce highly conductive patterns that are necessary for high-throughput large volume manufacturing of flexible and large area electronics. "In the "LOTUS" project we are focussing specifically on the applications that are already advanced and which provide us the biggest opportunities regarding to comercialization", says Prof. Schubert. As examples he mentions flexible thin-film photovoltaics for new energy solar cells, radio frequency identification (RFID) for reading out and printing on data carriers without any contact and the organic light emitting diodes (OLEDS) for lighting applications. "We aim to provide a simple, low cost, energy efficient, eco-friendly, and roll-2-roll (R2R) compatible technology to produce highly conductive structures in high resolution", tells Schubert.

Within "LOTUS", which is coordinated by the Holst Centre (Eindhoven, Netherlands), Prof. Schubert and his group are holding the task to improve new selective heating techniques for sintering various inkjet printed features. These shall be achieved at the lowest temperature as possible to allow the use of common polymer foils. "One of these methods is microwave radiation, which decreases the time of preparation significantly, comparable to the heating of food", project collaborator Dr. Jolke Perelaer explains.

From the cooperation between materials researchers, technology developers and end users in the framework of "LOTUS" the Chemists of the Jena University expect to gain innovative solutions, which can be realized quickly and effectively with a minimum of investment and time. "This also will accelerate the transfer to mass production", Prof. Schubert expects. "LOTUS" will strenghten the leading position of the European Industry in the range of flexible OLEDs, thin-film photovoltaics and RFIDs. "Furthermore the research project would be beneficial to any flexible electronic application, like thin-film transistors, power converters, flexible batteries or printed sensors for biomedical use and food protection", underlines the Jena Chemist.
