Reply To: Program Termination Error in Charge

[sumit.20dr0152]

Hi Khash,

Thank you for your detailed response and suggestions. I have carefully tried all the recommended steps, but unfortunately, the issue persists, and I am still encountering the same error. Here is what I have observed so far:

1. Material Bandgap: I changed TiO₂ and MoO₃ to Al(0.8)Ga(0.2)As and Al(0.3)Ga(0.7)As, respectively, as suggested. While this allowed the simulation to run without errors, it does not represent my actual device structure, so it doesn’t fully address the issue with my specific model.
2. Mesh Refinement: I experimented with both increasing and decreasing the mesh refinement and added local mesh objects targeting TiO₂ and MoO₃. The error remained despite ensuring the changes were reflected in the generated mesh.
3. Doping: I verified the doping objects in partition mode and ensured they were applied to the intended regions. I also increased mesh refinement in areas with higher doping, but this did not resolve the problem.
4. Imported Generation Profile: I tried using the reduced scaling factor in the import, but the issue still persists. When I tried running the model with the solar generation profile and adjusted the thickness of Al(0.8)Ga(0.2)As and Al(0.3)Ga(0.7)As to 10 nm (matching my ETL and HTL setup) in this (https://optics.ansys.com/hc/en-us/articles/360042160334-Thin-film-GaAs-solar-cell) model, the simulation ran without issues. 
5. Initialization Error: I confirmed that the starting voltage is set to 0 and swept up 1.5 volts with a step size of 0.01. Unfortunately, this did not change the outcome.

   If you have any additional insights or troubleshooting steps, I would greatly appreciate your guidance.
   Thank you again for your help!
