how to simulate the back-contact solar cell module performance?
Currently PVsyst handles PV modules with IBC cells in the same way as other crystalline Si modules. We have looked into this issue, and to our understanding, the shading advantage of this technology is limited to situations where only a few (1-4) PV cells of a substring in a PV module are shaded, while the other cells are fully illuminated.
