Typical workflow:
Play around with the parameters on the left and observe how the IV curve is impacted
Import one of your own data files (text file with 2 tab-separated Voltage and Current columns.
Here's a sample file
)
Take a look at the estimated parameters. Looking good? Then click on "Use estimated parameters"
You can adjust again the parameters manually, then start fitting (check the box next to a parameter's value to let it vary during optimization)
The optimization can be interrupted at any time by clicking on "pause", otherwise it will stop when the condition on dS is satisfied
