Comparison of iV_oc, V_oc and derived iV_oc-to-V_oc loss based on the median (green) and maximum (orange) observed for the two distributions for the TOPCon reference group (G1) and various SelFi TOPCon groups (G2-G7). The point markers show the individual measurement points and the box plots indicate the median value, the 25% and 75% quantiles and the minimum and maximum of the distribution.
