The Pilot Plant

The technikum is the heart of the photovoltaic research and provides a new technology platform for process development. In 2014, all essential equipment was procured and installed at approx. 200 m² laboratory and characterisation area. The equipment enables the possibility for the development of new synthesis methods, which allow the production of larger quantities (litre scale) of inks for roll-to-roll printing. The solar modules are manufactured by combining various printing techniques with laser structuring processes. This makes the manufacturing of complete components in a single operation possible.

  • Preparation and characterization of thin solution processed films of small molecules and polymers
  • Evaluation of existing and development of new coating and printing processes for organic solar cells and solar modules
  • Analysis and characterization of single layers, multilayers, solar cells and modules
  • Production of printed solar cells / modules
  • Development of Electrode materials
  • Development of structuring procedures and interconnection techniques
  • Scaling of printed cell layers to industrially relevant sizes (approx. 30 x 30 cm²)
  • Construction of a roll-to-roll pilot plant for the production of printed solar modules in an inline process and development of coordinated process steps
  • Lifetime of Organic Electronics: Encapsulation Processes and Investigations of Ageing Processes
