To investigate the solar cell performance, we first compare slot-die coated single-junction solar cells with the following layer stack: either BCP (bathocuproine) or SnO 2 between the fullerene (C 60) and Ag (or Cu) contacts. The former is typically used for opaque p-i-n solar cells, while the latter is needed for top contacts in tandem solar ...

The single crystal PERC solar cell needs laser slotting before printing, and the penetration depth is about 50–60 μm to ensure the good ohmic contact [18], [19]. However, in order to ensure the contact performance of passivation and avoid destroying the TOPCon layer, TOPCon does not use laser slotting.
