Organic light-emitting diodes (OLEDs) with thick carrier transport layers are desirable for high production yields of OLED-based displays and lighting; however, high operating voltages are inevitably introduced to thick OLEDs due to the low carrier mobilities of organics.

The associated Joule heating will also induce structural defects and lower operational stabilities. Here, the researchers demonstrate highly efficient and stable OLEDs with thicknesses of over 1 μm and low operating voltages.

The researchers used the advanced simulation software Setfos.
