Organic Light-emitting Diodes (OLEDs) and Transistors (OLEFETs)

While renewable energy generation is critical, the way we use our energy is equally important. OLEDs are an exciting new technology for flat panel displays and highly efficient lighting modules. In the lighting space it has been calculated that OLED lighting can be more than twice as efficient as fluorescent lights. COPE’s OLED activities involve the development of new light-emitting and charge transport materials, understanding the morphology, photophysical and charge transporting properties of the active layers, and finally the fabrication and testing of prototype devices. COPE’s focus is on solution processable materials such as light-emitting dendrimers that have the capacity for low embedded energy manufacturing. OLEFETs that combine the switching capabilities of field-effect transistors with the light-emitting properties of OLEDs and have the possibility of simplifying flat panel displays are also investigated.
