Extracting external quantum efficiency of OLED using FDTD


#1

Hello,
I have a question related to simulating OLED by using FDTD solution and hope someone can help.
How can I extract the external quantum efficiency of OLED (EQE) ? (The picture shown below is an example of extracting EQE of OLED using FDTD )
Thank in advance.

Hi @1672862

In the links below we explained how you can extract the quantum efficiency in OLED structure:

planar OLED:

https://kb.lumerical.com/en/index.html?stackdipole_and_fdtd_simulations.html

patterned OLED:

https://kb.lumerical.com/en/index.html?oleds_simulation_methodology.html

Based on the definition of external quantum efficiency in the paper you should be able to obtain the results from FDTD simulations.

Please let me know if you have any further questions.
