Title: does photocurrent module limited to illumination from sun?
Post by: korand on April 15, 2021, 12:36

Hi dear friends,
Does photocurrent module just calculate based on sun flux spectrum. I mean both flux and spectrums can be selected in the module. However, the energy spectrum range limits in this function from 0.3 to 4.5 eV make misunderstanding about the application of this module that it may exclusively belongs to photodetector illuminated by sun.

I want to use that to evaluate my IR detector.

Thanks in advance

Hi,
The photocurrent module does not rely on a specific photon flux. The solar spectrum is shipped with the software and the gui makes it easy to apply that, but any photon flux can be defined by the user.
In connection with IR detectors one would usually rely on the coupling with vibrations (generating infrared signals).
In that case I would point to the dielectric tensor analysis object:
https://docs.quantumatk.com/manual/Types/DielectricTensor/DielectricTensor.html
The gui has an infrared spectrum analysis tool that allows to plot the infrared signals (adsorption, dielectric constant etc).
