“Doped organic films in current optoelectronic device”


OLED became an established display technology and is being widely used in consumer
electronics, e.g. in (flexible) smartphones, laptops, wearables, tablets and TVs. Chemical doping of organic semiconductors (OSC) is an essential key concept and enables adequate performance and life-time of such products. This presentation will provide an overview of the existing device categories, with special emphasis on the respective doping strategies in mass production. The state-of-the-art dopant material classes that are most relevant for OLED application and organic photovoltaics will be presented. This will be followed by a brief summary of established mechanisms and how doping can improve the operating characteristics of various organic devices. An insight into production technology is provided, covering the processing routes for doped organic thin films, with a focus on the evaporation technique widely used in the OLED sector. Finally, challenges and prospects for chemical doping of OSCs are proposed to motivate future research in this area of applied research.
