On the device end, all the example circuits here share pretty much exactly the same code for serial transfer operations, though command processing details are naturally specific to each project.

Qucs is a GPL circuit simulator. And if you want the GUI option, you might want to try out QucsStudio, which uses Qucs under the hood, and is free to use, but binary-only.

Further details of the setup and the results are provided in the study “ Outdoor implied open-circuit voltage imaging of perovskite solar cells using sunlight excitation,” published in Joule.

The Chinese manufacturer said its Bycium+ PV cell achieved an open-circuit voltage of 748.6 mV. The result was confirmed by Germany’s Institute for Solar Energy Research in Hamelin.
