We have been trying to use SCAPS -1D to model Perovskite cells. We have been trying to replicate the attached paper by Hossain et al. The graph we tried to generate is given next. Our simulated Graph is then given. Finally we have also given the SCAPS file if someone can take a look and tell us. We are quite new to this and are probably skipping something but no matter what we do, we cannot get SCAPS to output the FF and Voc. We would be very happy and indebted to anyone who can tell us exactly where we went wrong.
Thank you in Advance
Tuning ( increase/decrease) of the the band gap and electron affinity simultaneously or adding the higher interface defect density can easily stop the extrapolation(absent situation of Voc/FF) of the device parameters. Best of luck.
I've run the single-shot simulation using your definition file. I think you will have your solution in a simple way: Make the voltage range V2(V) to at least 1.2 V (See attached photo - Capture.PNG). Besides, you need to tick on the box showing Stop after Voc.
In the attachment, you can now see the FF and Voc (Capture22.PNG).
Capture11.PNG shows the case of yours, when I used V2(V) of 0.8 V with no tick
on the box showing Stop after Voc.
Best regards,

Dear Faiyaz
Because we haven't seen all the introduced parameters in the simulator and all the buttons activated in the main window of the SCAPS simulator, unfortunately we cannot say where is your problem. So, I suggest to load an example from the proposed models in SCAPS tools, and try carefully to follow an example (e.g. ZnO / CdS / CIGS).
good luck.
