MorphoFlex: A Film Based Implementation of the MorphoColor Concept for Colored Photovoltaic Modules

The MorphoColor concept makes use of multilayer and structure interaction for colored photovoltaic (PV) modules. The photonic effect, inspired by the Morpho butterfly's wing, is optimized to produce saturated colors, a high angular tolerance of the color appearance and to maintain a very high module efficiency. This concept, implemented on textured glass surfaces, has already been applied to integrated photovoltaic modules. As a further development, we investigated implementing the MorphoColor interface on a polymeric film which then can be integrated into a PV module. This MorphoFlex concept enables twofold flexibility: for the production process as well as for curved modules. We will present the process chain for the film structuring, coating and integration, first results on film and module level, and show demonstrators.
