My sentaurus simulation of solar cells usually don't converge at the part after the illumination.
So before the doesn't converge part, the last successful part is the finishing of Raytracing part:
Summary of RayTrace Total Photons and Powers:
Input Escaped StoppedMinInt StoppedDepth AbsorbedBulk
Photons [#/s]: 7.392E+17 7.076E+17 2.989E+03
...
...
And then the next part is:
Starting solve of next problem:
Coupled ( Digits : 5, Max. #iterations : 30,
Solver : blocked decomposition,
#undamped iterations : 100
)
{ Poisson Electron Hole }
===============================
Computing Coupled( 1 poisson-equation(s) , 1 current-contact-equation(s) ,
1 electron-equation(s) , 1 hole-equation(s) )
using Bank/Rose nonlinear solver.
...
...
Finished because...
|RHS| increased to by more than 1e10.
So can someone tell me what is the problem here? I mean which part of the program is having problem and what kink of problem it is?
Hello,
maybe you could leave out the variables "Electron" and "Hole" from your des.cmd input file, and just solving the Poisson equation? I used it in a simulation and the solution didn't converge because of no current. But i am not expert about it, so don't care too much on my proposal, even if i hope to be useful.
Good work
