Certificate of innovation prize 2017/2018 of Netzwerk ZENIT e.V.

Netzwerk ZENIT e.V. presented the winners of their innovation prize which is in its eightth year. On 6 March 2018, in a ceremony held in the city of Mühlheim an der Ruhr, it was Prof. Dr. Andreas Pinkwart, Minister of Economy, Innovation, Digitization and Energy in the state government of North Rhine-Westphalia, who handed over the prizes in his position as patron of the competition. Next to the winner, five out of 22 companies who had submitted high-profile entries to the competition were honored with awards. This year’s competition motto had been „Cooperation as key to success“ and had motivated small and medium sized companies throughout the state of North Rhine Westphalia to apply for the prize with innovative product or service ideas based on cooperations with universities, research institutions or other companies.  Due to the extremely high quality of submissions it had been decided to honor a total of six projects. One of the five award-winning companies was Coatema Coating Machinery GmbH based in Dormagen and partner of the Fraunhofer ISC in the EU-funded EELICON project. Project leader at the Fraunhofer ISC is Dr. Uwe Posset who is happy to see his project win such acclaim.

Electrochromic materials can be switched electrically when integrated into a layer system with conductive materials: when an electric voltage is applied, charging takes place and the ion exchange results in coloration of the conductive layer. This phenomenon is especially useful for the shading of window panes. The innovative shading solutions and smart window technology of the Fraunhofer R&D Center for Electromobility Bavaria target automotive, architectural and aircraft markets. They enable glare protection or lighting control, improve thermal management and cut down energy consumption in air conditioning.

Current R&D priorities

The Fraunhofer R&D Center for Electromobility Bavaria develops novel electrochromic materials and tailored coating solutions for an efficient light management in windows and façades. Electrochromic features are particularly suited for electrically switchable glass and flexible films.

Our competencies

The Center’s integrated solutions offer maximum substrate variability, complementary active materials and gel/polymer electrolytes. The focus is on smart materials made of:

  • Conductive polymers
  • Complex metal compounds
  • Supramolecular metallo-polyelectrolytes

Electrochromic organic or inorganic films can be applied from wet-chemical precursors via fast and cost-effective roll-to-roll processing at low temperatures. Large scale application is possible.

Benefits of electrochromic solutions

  • Low switching voltages of a few Volts
  • Uses energy only for the actual color changes
  • Low current density during the shading process
  • High cycling stability even beyond 100.000 cycles (under lab conditions)
  • Excellent shading performance
  • Fast response time of just a few seconds
  • Can be retrofitted to existing windows


Our services to customers

  • Development of specific smart shading solutions
  • System development up to pilot scale
  • State-of-the-art electrochemical, spectro-electrochemical and climatic testing of existing customer systems
  • Battery research
