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 mid 2024. b) Same IV-curves but always moved by Isc of correlated intensity. Reverse breakdown occurs at around −48V slightly higher as the late 2023 TOPCon. There is a slightly more irradiance dependence visible compared to the late 2023 cell, resulting from a more sharp dark IV-curve breakdown point.
