I'm studying the perovskite solar cell through Lumerical FDTD simulation..
For example, I want to extract the absorbed spectral irradiance of Cs2AgBiBr6, but I can't find a script for it.
Can you give me some info on the script for this?
To extract the absorbed irradiance spectrum from a Lumerical FDTD simulation, you can follow these steps: 1) Run the FDTD simulation and obtain the time-domain electric field data for the structure of interest. 2) Fourier transform the time-domain data to obtain the frequency-domain data. 3)Calculate the absorbed power at each frequency by multiplying the frequency-domain electric field data by the complex conjugate and integrating it over the simulation volume. 3) Normalize the absorbed power data to obtain the absorbed irradiance spectrum.
4) Plot the absorbed irradiance spectrum as a function of frequency to visualize the results. 5) In Lumerical FDTD, you can use the "fourier()" and "sum()" functions to perform the Fourier transform and integration, respectively. You can also use the "pgroup" object to define the simulation volume for the integration step.
I hope this will help you. Best wishes Kyung Ho Seo
