QE calculation


#1

hello

I have difficulty in finding QE.

This type of graph has come up, but I can not confirm it.
I heard that the analysis group “QE” is only for dipole sources.

award structure - QE&abs.fsp (315.4 KB)

How can I get a graph of QE based on wavelength?
Should I use Pabs_adv? So how do I write a script command?

The ultimate goal is to get EQE.

DEVICE simulation is also difficult.

thank you

For a periodic structure with plane wave illumination, you will have to define your own QE, then you can calculate. For your case, do you know how to define the non-radiative emission?

Please refer the solar examples to calculate EQE, I guess you mean external quantum efficiency?

all the solar examples:

please read the getting started example first.
