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.
