Printable optics and optoelectronics

Printed and organic electronics are expected to grow a remarkable business of 250 – 300 billion USD in 20 years. When aiming to real mass volume markets like consumer packages, continuously running, roll-to-roll processes with high throughput capability are in key role. For example processing and fabrication of organic light-emitting devices and solar cells are nowadays carried out using traditional techniques such as spin coating and vacuum thermal deposition. However, these techniques have several disadvantages, e.g. material wastage and they are time consuming, and therefore, tremendous benefits are gained by incorporating roll-to-roll capable techniques, such as gravure printing and hot-embossing. In this presentation we show current status of roll-to-roll manufacturing of OLEDs, organic solar cells, diffractive gratings and lightguides.
