OLED

Seminar on Organic Electronics
In this lecture, the device physics of organic light-emitting diodes is treated. It is demonstrated how an organic light-emitting diodes works. The mechanisms of injection, transport and recombination of charges in organic light-emitting diodes are described. It is shown how the drift and diffusion current in a device can give information of charge transport and recombination. Furthermore, the impact of charge trapping and trap-assisted recombination on the efficiency of organic light-emitting diodes is treated. It is explained how the efficiency of these devices can be improved by the use of specialized materials and device layouts, eliminating exciton quenching and charge trapping. [mehr]
