I am trying to find out the the eqe of solar cell. In this respect, I swiped the lambda index parameter in device, however at points (wavelength around 600 nm), the charge solver was not converging, Will someone help me in that respect.
The error code is 9002 and it is saying that electrostatic potential was failed to update. I am attaching my whole simulation file (FDTD and Device in this respect)
(i.e: I am following the procedures that is suggested by @aalam in the “finding EQE of solar cell post” and I already updated the solver to newton and enable fast convergences in advance tab of Device, I disabled the Generation file and sweep parameter lambda, I hope you will found the procedure in following the example
