Reply To: x-y metalgrid of solar cell in CHARGE

Hi Handon,

I sincerely apologize for the late reply. We seem to have missed your question. 

Let me know if I understand the situation correctly. You have these grids in each unit cell. I assume that there will be a shadow under the metals where no light will be incident. In FDTD, you will have to do a 3D simulation. Then I think you can find an average of the generation rate over the cross-section so that it can be used in a 2D CHARGE simulation, similar to the approach used in the VPD example.

But I think you most likely will have to do a 3D CHARGE simulation as well. Do you expect the metal grid (also in the dead region) to have an impact on the electrostatic behavior of the solar cell? In other words, if you capture the generation rate from the 3D FDTD simulation, will you be applying bias to the entire grid? 

The question with regard to reducing the resources, is it on FDTD or CHARGE or both?

Regards,
Amrita
