bifacial TOPCon cell

This example defines a bifacial solar cell concept, typical for an industrial n-type TOPCon solar cell. It shows how to add a ploy-Si layer on top of a lumped skin to account both for parasitic absorption (FCA + band-to-band) and lateral conductance.

Another settingsfile is included showing how the extended Basore model describing bifacial optics in Quokka3 can be calibrated by fitting meausured reflection and transmission for front and rear illumination.

The downloaded archive contains Quokka3 settingsfiles for all of the input parameter sets presented in (Fell et al. 2015, JPV), namely a conventional, PERC, n-PASHA, HJT, ANU-IBC and UNSW-PERL cell. For each cell type a settingsfile exists where the the skins are defined by their lumped properties.

For the PERC cell and additional settingsfile is included which defines a much more complete and detailed model of the same cell. It comprises:
