Electrochromic materials is our passion

The use of electrochromic materials is a big part of our DNA as a company. Years of groundbreaking research at the Ångström Laboratory at Uppsala University have resulted in a unique patent portfolio that have given ChromoGenics an internationally leading position when it comes to developing electrochromic solutions.

We are not the only ones who strongly believe in the potential of electrochromic materials. Stephen Selkowitz, renowned building scientist at Lawrence Berkeley National Laboratory, USA regards electrochromic materials and glazing “as the most promising switchable technology for use in buildings.”

Putting atoms to work

In recent years, we have developed an electrochromic foil that revolutionized the market for dynamic glass. By using a multilayer structure between two electrochromic plastic layers, we create a flexible and lightweight ConverLight® foil capable of changing its degree of shading by applying a low electrical voltage.

In addition, the foil uses electricity only 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.

A unique glass laminate

The ConverLight foil is laminated between PVB foils and two tempered glass, which keeps it weather-protected. Since the ConverLight foil is flexible, ChromoGenics can, as the only supplier in the world, offer curved electrochromic glass. In addition to the dynamic properties, the only difference between ConverLight and ordinary glass is a two-pole cable connected to the laminate, which provides many functional and logistical benefits.
