Organic thin film electronics project

The Printed, Organic and Large-Area Realisation of Integrated Circuits (POLARIC) is a four-year, €9.9m project involving 13 partners from seven European countries.

Launched in January, the project aims to remove the barriers preventing large-scale production of organic thin film electronics to develop electronic products such as flexible sensors, photovoltaics, batteries and lighting.

Currently, the use of organic thin film transistors and circuits has been limited due to the inability of organic electronic components to maintain high-performance when using conventional high-volume production methods.

If we can do this, I believe we will open up many more applications for this technology

Project manager, Kimmo Solehmainen, said: ‘The main trick we are about to do in the project is to add a roll-to-roll compatible high resolution step in the transistor fabrication process. This will lead to smaller transistor dimensions and thereby increase performance.’

Roll-to-roll methods involve printing electronic devices on flexible plastic or electronic foil with rollers used to define the correct tension and position of the material.
