Implied V_oc and total recombination current density (J_0tot) of non-metalized and fired cell precursors for a TOPCon reference group (G1) and various SelFi TOPCon groups (G2-G7). The point markers show the individual measurement points (five points for each two cell precursors per group) and the box plots indicate the median value, the 25% and 75% quantiles and the minimum and maximum of the distribution.
