Organic photovoltaics is dedicated to the research of highly efficient, stable and scalable materials (organic molecules and polymers, chromophores and additives) for organic solar cells. In addition, the use of environmentally friendly and industrially compatible ink formulations, the scalability of solar cells to approx. 30 x 30 cm2 and the printability by means of different coating processes for industrial applications are investigated. Both printing processes for the production of single layers and roll-to-roll processes are considered.
As the heart of photovoltaic research, the pilot plant provides the process technology framework for the new technology platform. In 2014, all essential equipment was procured and relocated or installed to the approx. 200 m² laboratory and characterisation area. With the help of the equipment, the possibility for the development of new synthesis methods is created, which also allows the production of larger quantities (litre scale) of ink formulations for roll-to-roll printing. The solar modules themselves are manufactured by combining various printing techniques with laser structuring processes. This makes it possible to manufacture complete components in a single operation.
