The leader of the TREASORES project, Prof. Frank Nüesch of the Swiss Federal Laboratories for Materials Science and Technology (Empa), was interviewed in the summer of 2015 for the Swiss cable television channel Homegate TV. The interview (in Swiss German) concerned the possible uses of thin flexible organic photovoltaics from the TREASORES, and can be seen here (from 7:00).
Dr Michele Sessolo from the TREASORES partner the university of Valencia is co-organising a session at the large autumn meeting of the Materials Research Society. The session will be concerned with organic biolelectronics, and the deadline for submissions is 18th June 2015. For more information see here. (The meeting takes place from 29th November to 4th December 2015).
Several TREASORES partners led by Dr. Roland Steim from Empa (the Swiss Federal Laboratories for Materials Science and Technology) recently published a paper with the title Laminated fabric as top electrode for organic photovoltaics in the journal Applied Physics Letters (vol. 106 Issue 19). For a limited time, the paper can be downloaded free from the previous link, afterwards it may be obtained normally with the citation or as DOI: 10.1063/1.4919940.
The paper describes the use of one of the electrode materials refined within the TREASORES project to construct organic photovoltaic devices (i.e. solar cells), and states that this approach with a woven electrode is very promising for solution processed devices (being in principle easily scalable to roll-to-roll production).
Organic and printed electronics relates to emerging electronics beyond silicon technology. In this growing multibillion Euro market, the need for new standards has led to the creation of multiple working groups within various standardisation forums. In order to support companies to find relevant standards and to engage with standardisation activities, NPL, in collaboration with the Versailles Project on Advanced Materials & Standards (VAMAS), has prepared a report that details the current landscape of standardisation efforts in organic and printed electronics.
The fast pace of this growing industry, combined with the flexibility of product design poses a challenge to standardisation. The aim of this report is to provide an overview of the different organisations already engaged in standardisation and pre-standardisation in this area and a brief summary of the activities of these groups. The report, prepared by Dr Fernando Castro (NPL representative on VAMAS as chair of Technical Working Area 36: Organic Electronics), was partially supported by the Framework 7th Programme project TREASORES (FP7 contract number 314068) that aims to develop roll-to-roll manufacturing of large area organic electronics.
The report covers areas such as testing of flexible printed electronic devices, functional/electronic inks (e.g. carbon nanotubes, metal nanoparticles, graphene…), characterisation of organic light emitting diodes (device level and displays), photovoltaics (device level), thin film transistors and barrier layers. It also includes information about how companies can obtain technology verification when no standards exist. A list of current standards and proposed work items within relevant standardisation groups is presented and a heat-map of activities provides a visual guide to the distribution of activities among the different groups.
VAMAS TWA36 Organic Electronics would welcome new members and would appreciate any suggestions of topics for pre-standardisation work. In addition, a measurement protocol developed by NPL might also be of interest to researchers in organic electronics. The protocol Towards reliable charge-mobility benchmark measurements for organic semiconductors is available from this link.

The coordinator of the TREASORES project, the Swiss Federal Laboratories for Materials Science Research and Technology (Empa) issued a press release in March 2015 summarising the results of the project at the half-way stage, focussing on flexible OPV devices and the new silver electrode technology that has been developed and scale-up by the project as an alternative to Indium Tin Oxide (ITO).
2015 has been declared by the United Nations to be the International Year of Light and Light-based Technologies, in order to raise global awareness about how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture and health. A number of events and exhibitions are planned through the year, although the TREASURES project members are not currently directly involved in any. See http://www.light2015.org/Home.html for more information.
The Technical University of Dresden, a partner in the TREASORES project, recently published results that are important to improving the manufacturability of transparent flexible electrodes made from silver nanowire networks. The peer-reviewed paper in Organic Electronics discusses a method of improving the conductivity of silver nanowire electrodes using only low-temperature processes – i.e fully compatible with plastic substrates and barrier layers. The team at Dresden went on to show that the new technique led to efficient solar cells without the previously used temperature annealing step for the nanowire electrode network.
The TREASORES project partner Canatu Oy recently made their first sales of transparent conductive electrodes to a customer in Asia. Canatu’s technology (partly developed within the TREASORES project) utilises the dry deposition of a form of carbon nanotubes (trademark Carbon NanoBud or CNB) directly onto the flexible substrate to give a highly transparent, conductive and flexible electrode coating. For more information, see the press release from Canatu. The image below shows the roll-to-roll production line at Canatu’s premises in Finland.
