EU Project Treasores announces transparent silver electrode (TSE)

A transparent electrodes is required to replace ITO in applications such touch sensors, displays, OLED lighting, OPV, smart windows and EMI shielding

14 Sep 2015 | Editor

The EU funded R&D project Treasores has announced that Rowo Coating has developed together with the Fraunhofer Institut für Solare Energiesysteme a transparent conductive multilayer stack on the basis of a thin silver layer embedded in metal oxide layers with a visible transmission of more than 86 % and sheet resistances down to 7 Ω∕□ which is far below ITO with minimal 45 Ω∕□ on flexible substrates.

This TSE multilayer stack can be adapted to the corresponding application to meet the optimal properties. In addition to sample sheets Rowo Coating is able to deliver small rolls up to 1,300 mm in width.

Currently ITO (indium tin oxide) is the dominant transparent conductor for all applications requiring a transparent electrode like touch sensors, displays, OLED lighting, OPV, smart windows and EMI shielding. However, due to its high price and limitations in future resources worldwide efforts are underway to develop alternatives to ITO.

About Rowo Coating

Since 1991 ROWO Coating is active in the field of vacuum coating of flexible materials like plastic films, wovens and nonwovens with different metals, metal oxides and alloys by means of thermal evaporation and sputtering up to a maximum width of 1.650 mm.

Electrical conductive, shielding, reflecting, isolating, bactericidal, decorative, gas barrier are properties which could be realized by means of our coating techniques.

Our coated substrates find their application in the construction industry, electronics, medicine, shielding technique, solar energy, winter sports, decoration, and food packaging.

Together with partners from the industry, universities and R & D laboratories we work in projects with public funds to create new coating techniques or products.

About TREASORES (EU project)

TREASORES is an EU funded project (FP7 contract number 314068) concerned with the cheaper production of large area organic electronics such as lighting panels and solar cells. This will be achieved by developing materials and processes that are compatible with roll-to-roll processing technology, in particular transparent electrodes, barrier foils and encapsulation layers.

The project is led by Prof. Frank Nüesch of Empa (the Swiss Federal Laboratories for Materials Science and Technology).

Fraunhofer Institute for Solar Energy Systems (ISE)

The Fraunhofer Institute for Solar Energy Systems ISE conducts research on the technology needed to supply energy efficiently and on an environmentally sound basis in industrialised, threshold and developing countries. To this purpose, the Institute develops systems, components, materials and processes in the areas of the thermal use of solar energy, solar building, solar cells, electrical power supplies, chemical energy conversion, energy storage and the rational use of energy.

The Institute's work ranges from fundamental scientific research relating to solar energy applications, through the development of production technology and prototypes, to the construction of demonstration systems. The Institute plans, advises and provides know-how and technical facilities as services.
