... please help me to extract the series Rs (Rs1, Rs2, Rs3, Rs4, Rs5, Rs6)and shunt Rsh (Rsh1, Rsh2, Rsh3, Rsh4, Rsh5, Rsh6) resistances of each IV characterization

Sorry, wachhad, I'll not be running your job: that's your part. You wrote:

yes I think I can easily to create such an Excel file to calculate R = δV/δI values like what you do in solar_cell_characteristic.pdf , But I have not a method to calculate Rs and Rsh from R = δV/δI excel column

I told you how to calculate these resistor values in my answer #15. So you should be able to calculate these values yourself!

Dear erikl, hello (aslam alaikom)
Thank you erikl, my problem is I not have the time, I'm busy a lot,
Dear erikl are you in microelectronic field and mastered the use of TCAD silvaco Atlas package ?
Because I am a beginner and I am in need to help me in my project which entitled "Study and Simulation of Electrical Properties of organic photovoltaic cells based on new polymers (π-conjugated)" using Silvaco TCAD,
If you in this field and mastered the use of TCAD silvaco Atlas package I have some simulation problems,
If you are not please transfer my request to peoples you think whose can help me (Colleagues, professors, university students,forums, ...etc), or send to me their Email addresses,
Because in this forum I did not find any help,
I have the honor to benefit from your experience again,
So please help me as soon as possible,
With my best wishes,
Thank you in advance.

Hello wachhad,
I've never used TCAD myself, sorry. There have been several threads on TCAD problems in this forum, including answers from specialists. Just search for TCAD and you'll find them. If you post specific and tangible questions you'd surely get help.

Good luck! - erikl
