GW-News: Mr Geisler, why are coloured solar modules so important for building design?
Holger Geisler: The requirements for building envelopes are becoming increasingly complex. In addition to function and sustainability, aesthetics play a decisive role. Particularly in the case of building-integrated photovoltaics (BIPV), visual appearance is crucial for architects to include such systems in their designs. With our ColorQuant technology, we can offer colours for PV modules that meet aesthetic and energy requirements. Architects can have individual colours developed for each project without significant compromises in efficiency.
GW-News: What distinguishes your ColorQuant technology from other approaches on the market?
Our approach is based on the physical principle of interference. The printed colour layer specifically reflects only the desired colour tone instead of absorbing sunlight. As a result, the efficiency of the solar modules is almost completely retained - with an almost unlimited variety of colours.

Another difference lies in the flexibility: architects and module manufacturers can have individual colours developed by us for specific projects. We also archive every colour mixture so that it can be reproduced at any time - even years later. No other colour supplier has ever achieved this level of adaptability.
GW-News: How does Ceramic Colors Wolbring work with architects and module manufacturers?
We attach great importance to working closely with architects, module manufacturers and facade system suppliers. Our goal is to jointly develop customised solutions that fit seamlessly into existing facade systems. The PV glass produced with our colours can be easily integrated into the standard systems used in the facade construction industry.
