Sunny prospects: Under the direction of the Fraunhofer Institute for Laser Technology ILT in Aachen, five project partners from industry and research are developing technologies for the roll-to-roll production of organic photovoltaics in the EffiLayers project. This North Rhine-Westphalian lead market project aims to help the machine manufacturers based in North Rhine-Westphalia play a pioneering role in the market for flexible thin-film solar cells and printed electronics.
It is about organic photovoltaic cells (OPV cells), which are less efficient than traditional silicon-based solar cells, but are flexible and transparent. These last two advantages allow OPV cells to be functionally and decoratively integrated, for example, into building facades. By developing an efficient production process, the partners intend to boost the industrial mass production of OPV cells.
