Coloured Module Glass for BIPV inspired by Morpho Butterfly

Colored Module glasses with high angle tolerance can be achieved by using the photonic effect discovered on high transmission is demonstrated. In a BIPV module, a homogeneous appearance with saturated color will be achieved by using a black back sheet and black interconnect wire or back junction cells. Fig. 2: Demonstration of the color effect for a mini module. The glass panes are applied with a water film. For large area demonstration, the functional layer was applied to glass panes of the format 109 x 112 cm2 (Fig. 3). These glass panes will be used for PV module lamination and installation in a demonstration facade at Fraunhofer ISE (installation planned in autumn 2016). Fig. 3: Large area demonstrator on an area of more than 1 m2. In the bright green area the strong color is visible since a black screen was positioned behind the glass. In the surrounding areas the high transparency can be seen. In the center and at the bottom reflections of the flashlight are visible.
