Through a combination of "optimizing PV performance" and "minimizing power losses through coloring", SUNOVATION masters the balancing act between module optics and module performance with this new color collection: coloring of photovoltaic modules inevitably leads to a certain reduction in PV performance. The challenge in the development and production of colored solar modules is to minimize this undesirable influence. SUNOVATION eFORM unichrome glass-glass-modules are configured individually according to customer requirements. A special manufacturing process (SCET - Sunovation Cell Embedding Technology) enables the production of precisely fitting modules with individual glass structures. The use of high-performance crystalline PV cells, integrated diodes and an individually optimized cell layout results in maximum PV-output/m². Combined with a specially developed technology for coloring, the exclusive collection of high-performance colored PV modules for building integration has been created. Based on coloring by interference, the sunlight is split up like in a prism. Light needed to generate energy continues to reach the PV cell through the colored layers, while the wavelengths responsible for the coloring are selectively reflected. The influence of the coloring on the performance of the PV cells is reduced to a minimum by using this technology.
The colored glass-glass modules are used in particular in solar facades. "In the last two years, we have seen a significant increase in demand from architects and building owners for aesthetically pleasing PV-modules that can also make a relevant contribution to energy generation in the building envelope," says Heribert Ley, Managing Director of SUNOVATION. "The "ColorQuant" collection is therefore very well received by our customers. The first facade projects with new color shades are already ordered and will be realized in 2022." Unlike other colored PV modules, the integrated PV cells remain invisible in all weather conditions and retain their colored glass appearance from all viewing angles.
