Before it can take over our streets and homes, OLED lighting needs to be made more accessible. The SOLEDLIGHT project has developed novel multilayer OLEDs thanks to a new process that promises to increase production efficiency by 20 %, thereby reducing its cost. Benefitting directly from the PI-SCALE project – which involves the creation of pilot lines for the production of flexible OLEDs using roll-to-roll deposition methods – SOLEDLIGHT (Solution Processed OLEDs for Lighting) successfully developed multilayer OLEDs with power efficiencies achieving 20 lm/W.

Whilst not yet on par with vacuum-processed equivalents, the new devices are hoped to achieve 100 lm/W and lifetimes superior to 15 000 hours by the end of the project. Dr Henk Bolink, researcher at the University of Valencia and coordinator of SOLEDLIGHT, discusses the project’s achievements so far and its potential, notably in general lighting and automotive applications.
