Abstract:
We show how to construct an equivalent circuit for our Mercury FFE IBC cells to model features
beyond the unit cell efficiently, taking into account the lateral hole transport in the FFE. We
show how its predictions can be correlated with voltage maps of the FFE voltage, and used for
optimum design of for instance busbars.
The highest efficiency of our Mercury FFE IBC cells to date is 20.9% with a short-circuit current of 41.3 mA/cm2, obtained with screen printed contacts.
