November saw the 5th technical meeting of the TREASORES project after two years of work. At the meeting, held on the premises of project partner CIC nanogune in San Sebastian/Donostia Spain, it was reported that progress to date has been good and that medium-scale production of the barrier layer substrates and electrodes chosen six months ago for scale-up work at the half-way point of the project has begun. This medium scale work is being done using roll-to-roll production techniques with several hundred meter lengths. Larger scale production of materials for testing (including device fabrication) is expected in the 1st quarter of 2015.

The project has also completed it’s formal mid-term review and reporting processes with the European Commission. Following useful advice from the commission’s external reviewers, the project’s internal decision process for selecting new substrate and electrode technologies has been made more transparent, especially in terms of linking the technologies to potential applications areas (for both lighting and photo-voltaic devices). The commission made it clear that the TREASORES project must not only produce technically useful materials, but that it should be possible to (eventually) make them cheaply enough to compete against existing materials such as ITO electrodes: the project partners believe that they will have succeeded in demonstrating this by the end of the project in October 2015.


Scientists working on the TREASORES project at the University of Valencia in Spain, and the Fraunhofer Institute for Solar Energy in Germany, together with colleagues from other institutions, have shown that power conversion efficiencies in excess of 7% can be achieved for perovskite based solar cells on flexible organic substrates, even when repeatedly flexed. This makes the technology eminently suitable in future for roll-to-roll manufacture, and thus lower costs per unit area. The research was described in the Royal Society of Chemistry Journal “Energy and Environmental Science” .

Prof. Frank Nüesch of Empa and EPFL, the coordinator of the TREASORES project, was interviewed by the Swiss popular science programme ‘Einstein’ for the episode screened on 27th February 2014. The interview concerned his views of the effects upon Switzerland of not joining the EU’s ‘Horizon 2020’ research programme as a full partner (a possible consequence of a recent Swiss referendum limiting immigration).

There is a new cluster of institutions in Dresden known as FLEET – Flexible Electronics Encapsulation Technologies. The TREASORES partner COMEDD is one of the participating entities, together with two other Fraunhofer institutions (FEP and IWS), the Institute of Applied Physics at the Technical University of Dresden (also a TREASORES partner) and the company SEMPA systems.

Dr Roland Steim from the TREASORES partner Empa has made a video of an organic solar cell on a flexible substrate from the TREASORES project powering a small motor. The flexible solar cell has been taped to a piece of glass for convenience; when it is exposed to the light, power is generated and causes the fan to rotate.

In order to reflect changes in the competences of the original consortium, and to strengthen the life-cycle analysis of the new materials and devices developed by the TREASORES project, the company Quantis Sàrl has joined the project consortium with effect from October 2013. Quantis are an international company based in Switzerland with proven expertise in life-cycle analysis and  sustainable development. In 2013, part of the Empa life-cycle analysis group moved to Quantis see press release.



Several members of the TREASORES project were present at the Organic and Printed Electronics Conference held in Munich in June 2013, and Sandra Kiese of the Fraunhofer Institute for Process Engineering and Packaging (Fraunhofer IVV) presented a poster on
Transparent high barrier films for flexible organic electronic devices.

As the TREASORES project comes to the end of its first 12 months, the first results from the project have been published. Christoph Sachse and his colleagues from the Technical University of Dresden have a paper in Advanced Energy Materials reporting the performance of a small molecule solar cell on a copper nanowire electrode, and Patrick Reinecke of the Fraunhofer ISE presented a poster at the Plastic Electronics Conference in Dresden concerning the performance of polymer based solar cells on a flexible silver electrode from Rowo Coating.

Cheaper Devices

The TREASORES project will allow cheaper fabrication of organic electronics, and so more affordable consumer devices.

Flexible Devices

The technology developed by TREASORES will allow devices to be flexible.

Better Devices!

TREASORES will create more efficient solar cells and light sources.
