TRPL simulation for solar cells are much similar to the IV simulation format in sdevice file. Except you replace the quasistationary solver with a transient solver.

It's better start the transient solver with poisson solver to provide good initial values for the solution variables.

eg:

* Equilibrium Solver

coupled{Poisson}

plot (FilePrefix = "n@node@_Poisson")

* Transient Solver

Transient

(

InitialTime = peak_pulse_time

FinalTime = XX_secs + peak_pulse_time

InitialStep = 0.1e-9 (sample value)

MinStep = 1e-20 (sample value

MaxStep = 0.1e-9 (sample value

){

Coupled{Poisson Electron Hole}

Plot(FilePrefix= "Name_of_tdr_plot_file"

Time = ("Time_value_at_which_you_want_extract_trd_file") )

}

Make sure that time steps are not too long or you might convergence issues.
