![]() Merck oversees its applications ensuring the implementation of all formats and sizes up to the jumbo format of 3210 × 6000 mm. AG Who is involved? Players and logisticsĮmploying ColorQuant TM features to its best potential implies multiple players including PV panels manufacturers and glass finishers. Modules produced and delivered by Ertex-Solartechnik and installed by Felix & Co. in electric mobility systems, where the extension of the available support area or battery related issues represent the major restrictions. On the other hand, customized colors and appearance does not solve all problems of PV usage, i.e. can be disposed of without any special effort. For glass finishers who use ColorQuant colors, this means that there are no high additional or recycling costs for disposal, as color residues etc. Modules produced and delivered by Ertex-Solartechnik and installed by Clevergie Pros and cons: an objective viewpointĪ technology capable of transforming the aspect of devices providing renewable energy has great implementation potentials, even more considering the colors are produced with water-soluble, environmentally friendly ceramic, no hazard labeling is required according to EU directives. Solarhäuser Reichenburg (source: © clevergie.ch). In fact, as ColorQuant TM PV colors were developed jointly by Ceramic Colors Wolbring and Merck especially for facade-integrated PV elements, this line of design and production can find further developments. However other product categories, which have typically found one and only aesthetic definition would naturally welcome PV cells or panels: automotive and transport, lighting, and many outdoor functional structures.Īccess to an unprecedented palette of colors or the ability to create translucent finishings provide to designers a new vocabulary to experiment in a wider variety of products and, most significantly, of building integration. Most applications to date were geared towards architectural installations. Colored solar installation by Sunovation – © SunovationĮxtensive application of PV roof paneling has often become an unwanted feature in the built environment because of its visual presence, dark and in contrast with the surrounding elements due to the color limitations associated with its silicon-based modules, which can reach only blue to black tones. ColorQuant™’s applicationsĬolorQuant TM is posed to significantly impact the use of PV modules in visually sensitive projects at architectural and product design levels. At the same time, a rich, however translucent color is achieved. The result is only a minimal – around 10% – loss of power from the solar module. Only those wavelengths are selectively reflected that are necessary for coloring. The ColorQuant color layer lets through the light that the solar cell needs to generate energy. In this process, the incident sunlight is split up like in a prism once it hits inorganic and environmentally friendly pigments. The colors’ structure is based on coloring by interference. To obtain these colors, water-soluble ceramic pastes are used. The scheme below shows the composition of a photovoltaic panel and where ColorQuant TM can intervene. When it comes to glass color integration, color can be applied by screen printing, roller coating and spray application on the front glass, or in the encapsulant film that can be placed right after it. ![]() Photonic pigments can be implemented in PV modules in different ways. Interference through dielectric stacks was too complex, light angle sensitive, expensive and unstable, while ColorQuant TM photonic pigments resulted in highly purified and validated colors, which ensure stability of solar performance and long lifetime of color performance. The studies building up to the development of ColorQuant TM investigated different approaches: from organic coloring, deemed unsuitable for degradation risks to absorbing pigments, inefficient because light blocking, containing toxic elements and finally resulting in dull colors. This technology fulfills all stability requirements, can be easily integrated into solar modules, and is convincing for its very good price-performance ratio as well as a reasonable service life in terms of efficiency and quality. ![]()
