a) IV-curves taken at 1300W/m2 and from 1100W/m2 to dark IV in 100W/m2 steps of a 16 busbar TOPCon mono-crystalline half-cut cell from Figure 8, manufactured late 2023. b) same IV-curves but always moved by Isc of correlated intensity. Reverse breakdown occurs at around −44V significant higher compared to PERC and Al-BSF cells. There is almost no irradiance dependence visible, and please note the different, zoomed in y-axis scaling compared to PERC/Al-BSF.
