The 156.75 mm (M2) size, 180 μm-thick, p-type (Ga-doped) c-Si wafers with resistivity of 0.8–1.0 Ω cm were used to fabricate both PERC and p-TOPCon solar cells. To minimize the process-induced variations, both cell precursors were fabricated in parallel, as shown in Fig. 2.

Observations of contact resistance in TOPCon and PERC

Previous studies have investigated the cause of this rapid reduction in FF in p-type mc-Si passivated emitter and rear cell (PERC) devices [28, 29] an et al. showed that the increased R S was unstable following the application and removal of a forward current. This indicates that the changes in R S cannot be fully explained by a thickening of the glass layer at
