OLED

Description

Materials development has played a vital role in the dramatic improvement of organic solar cell performance in recent years.

Fullerene is used as an electron transport layer to further enhance the electrical performance of the cavity device and the optical tuning of the cavity OLED.
This fullerene layer results in a ∼2V driving voltage reduction and a ∼20% increase in power efficiency, as compared with traditional cavity OLED with Alq as the electron transport layer.

Applications

  • Metal/fullerene bilayers have been studied as hole injection electrodes for use in organic light-emitting diodes (OLEDs). In the case of a simple emission zone structure, it is found that OLEDs with the Au∕C60 anodes have much lower (∼10V) driving voltages and much higher current efficiencies (five times higher) than OLEDs with a simple Au anode.
  • This anode structure was found to be applicable for all types of light-emitting structures including fluorescent and phosphorescent dye-doped systems.
