Challenges in organic electronics UK

5-6 November 2007
The Core Technology Centre
This two day meeting was organised by the Organic Materials Innovation Centre (OMIC) and the UK Displays & Lighting KTN and focused on research activities that address the major challenges in the chemistry, processing and physics of organic transistors, sensors, OLEDS and photovoltaic devices as well as the key challenges to industry in bringing this groundbreaking technology to the marketplace.
The keynote presentation on the first day was delivered by Sir Richard Friend and described challenges and prospects on how to do electronics with molecules and how to process them. Direct printing was considered an efficient way of bringing cost down. Singlet/triplet spin ratios and the possibility of strong spin/orbit coupling leading to emitting triplets were discussed. In photovoltaics in specific, the need for clean heterojunctions and charge separation in excitons were also highlighted along with efforts to bring up quantum efficiencies in polymeric blends.
Mike turner gave an overview of OMIC and its activities in his presentation and Harry Anderson of Oxford University focused his talk on supramolecular control of organic semiconductors and the encapsulation of conjugated polymers.
Further talks on polymer processing for organic electronics applications revolved around ordered polymers and the use of hydrophobic/ hydrophilic properties to achieve different configurations, studies of nanoparticle infiltration in polymer brushes, nanocomposite materials and structures, semiconductor polymer lasers, OLEDs and studies on application and optimisation of organic blends for solar cells.
George Baxter kicked off the second day of the event with an overview of investment activities and potential of the North West of England, highlighting the importance of networking & collaboration in helping to turn investment in science and technology into wealth.
Michael Lebby (OIDA) and Wolfgang Mildner (Poly-IC & OEA) delivered the keynote presentations. Michael Lebby focused on the industrial perspective of organic electronics and on forecasts in the next 10 years: anticipating future trends such as aging population, energy issues, data explosion, food & water, would help guess where science and technology will lead. Examples include: According to Michael, the photonics industry will be a $1 trillion industry by 2017, as predicted both by OIDA and their Japanese counterpart OITDA. Solid State lighting will emerge and displays will be the biggest component. Despite the huge polymer potential, the biggest challenge for OLEDs is the need for "killer applications" in order to prosper against the domination of LCDs.
Wolfgang Mildner described the activities of Poly-IC, focusing on the completely roll to roll manufacturing process of printed 13.56 MHz RFID tags, made of polythiophene on polyester substrate at a rate of 20m/min. He also described the activities of the OEA, with its 85 member-companies that contribute information to the network. Build bridges, help the growth of the industry, promote R&D, educate, train, enhance public relations and push standardization. The 2nd edition of the OEA roadmap for organic electronics provides the evaluation of 7 application areas: Photovoltaics, organic memory, organic TFT backplanes, printed RFID, flexible batteries, organic sensors and smart objects as combination of different devices. He also described the OEA flexible multifunctional demonstrator which was assembled under the coordination of Poly-IC.
Further talks described organic electronic activities in Brazil and potential opportunities for collaboration, (Osvaldo Oliveira Jr, Instituto de Fisica de Sao Carlos), the development of high performance materials and technologies for the OLED industry in order to gain market share over LCDs, (Melddyn Jones, OLED-T), material challenges in organic TFT devices, (Ian McCullough, Imperial College London), the use of inorganic quantum dots in organic electronic devices, the full scale production of organic active matrix backplanes and updates on the status and capabilities of the PETeC centre.
This very successful meeting was attended by 100 delegates approximately and provided insight to the numerous of research, development and exploitation activities on the vibrant field of organic electronics.
