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.
