IM³OLED Project to Develop Multiscale OLED Modeling Tool

The EU-funded IM³OLED (Integrated Multidisciplinary & Multiscale Modeling for Organic Light-Emitting Diodes) project - coordinated by Holst Centre and the Russian National Research Nuclear University MEPhI - has officially been launched. An international collaboration with the Russian Federation, the project aims to develop a software tool for multiscale OLED modeling. Such a tool would help the OLED industry escape today’s “trial-and-error” development and accelerate towards the goal of 150 lumens per Watt devices.

Overall OLED efficiency depends on many factors: the properties of the light emitting molecules, deposition on to the substrate, integration into a device, extracting the light from the active layer and the device, heat management and more. Complicating things further, many of these factors are interlinked. For example, how the device heats up in operation may affect the molecules’ ability to generate light and the way light travels through the device. This makes it extremely difficult to predict how innovations in one area will affect performance in others, leading to a trial-and-error approach in R&D.

Enabling OLED optimization:
IM³OLED aims to help the OLED industry speed up development by creating new modeling software that allows a more systematic R&D process. This software toolset will predictively model OLEDs in 3D and at all length scales – from molecular to large-area devices. It will include molecular calculations, electrical and optical simulation, 1D-3D light extraction and scaling / integration effects. Importantly, the tool will incorporate a dynamic feedback loop, enabling developers to accurately predict how changes in one area of OLED development affect other areas. This will allow multiple OLED properties to be optimized simultaneously.

“IM³OLED will develop, evaluate and validate a predictive multi-scale and multi-disciplinary modeling tool. Making such a tool available will accelerate progress of OLEDs for lighting applications and allow the European OLED industry to strengthen its leading position in this environmentally important, global market,” said project coordinator Stephan Harkema.

Euro-Russian network of industrial and academic partners:
IM3OLED brings together industrial and academic partners from across Europe and the Russian Federation and is coordinated by TNO/Holst Centre and by National Research Nuclear University MEPhI. Industrial partners include OLED manufacturer Philips Electronics and specialist in simulation software SMEs Fluxim of Switzerland and Kintech of Russia.

Academic partners include leading computational physics and atomic / molecular modeling groups from the Zurich University of Applied Science (ZHAW) and Russian Academy of Sciences’ Photochemistry Center (PCC RAS).

Funded through the European Union’s Seventh Framework Programme (FP7NMP Grant no 295368), the EU portion of the IM3OLED project will run for 30 months until late 2013.

About TNO/Holst Centre:
With more than 4000 professionals, TNO is the largest Dutch organization for applied research. The activities of TNO within IM3OLED are being conducted by its research division at Holst Centre. Holst Centre is an independent open-innovation R&D center, set up in 2005 by Imec (Flanders, Belgium) and TNO (The Netherlands). Holst Centre develops generic technologies for Wireless Autonomous Sensor Technologies and for Flexible Electronics. A key feature of Holst Centre is its partnership model with industry and academia around shared roadmaps and programs. It is this kind of cross-fertilization that enables Holst Centre to tune its scientific strategy to industrial needs. Holst Centre was setup with support from the Dutch Ministry of Economic Affairs and the Government of Flanders. It is named after Gilles Holst, a Dutch pioneer in Research and Development and first director of Philips Research. Located on High Tech Campus Eindhoven, Holst Centre benefits from the state-of-the-art on-site facilities. Holst Centre has over 170 employees from 28 nationalities and a commitment from over 30 industrial partners. More information: www.holstcentre.com

About National Research Nuclear University (MEPhI):
Moscow Engineering Physics Institute (MEPhI) was founded in 1942 as Moscow Mechanical Institute of Ammunition; the main mission was training personnel for the Soviet nuclear program and scientific researchers in the field of nuclear phenomena and its applications, with the development of accompanying technologies like electronics, materials technology and so on. In 2009 MEPhI got the status of National Research University and joined about ten organizations. Now National Research Nuclear University “MEPhI”, only in its Moscow branch, includes more than 70 scientific and
