"Electrochromic glazing is the most promising switchable technology for use in buildings." – Stephen Selkowitz, Lawrence Berkeley National Laboratory, USA
ChromoGenics has an internationally leading position for electrochromic materials, and many years of research at the Ångström Laboratory have led to a unique technology and patent portfolio.
By using a multilayer structure comprising several different materials between two plastic films, we create a flexible and lightweight ConverLight™ foil capable of changing its degree of shading by applying a low electrical voltage.
Theres additional good news: the foil does not use electricity except when the shading is being altered. This makes it very energy-efficient in comparison with other technologies for regulating shading.
An electronic control unit can regulate the foil's shading, either manually or automatically, for example, by connecting it to a sensor network.
From advanced material science to practical success ChromoGenics was established in 2003 as a natural outcome of over 20 years of research on electrochromic materials by Professor Claes-Göran Granqvist and his team at the Ångström Laboratory at Uppsala University in Sweden. Today ChromoGenics has over 20 employees, most of them development and production engineers.
Our facilities include a 600m² modern cleanroom environment with a pilot production line for ConverLight™ dynamic glass in sizes up to 1,5 x 4,4 m, as well as automated testing and a glass lamination laboratory.
To scale up production further, we are establishing a high-capacity production plant using our unique roll-to-roll (R2R) coating process for electrochromic material.
ChromoGenics has built up a strong patent portfolio covering essential materials, processes and applications in eighteen patent families, the last one to expire in 2033. Additional patents are pending. The company also has substantial know-how in the field of production technologies, strenghtened by partnerships with major manufacturers.
