a) IV-curves taken at 1300W/m² and from 1100W/m² to dark IV in 100W/m² steps of a 9 busbar PERC mono-crystalline half-cut cell from Figures 5a, 5b. b) same IV-curves but always moved by Isc of correlated intensity. Reverse breakdown occurs at around −23V as expected for that solar cell type. A strong irradiance dependence is visible at voltages lower than −5V compared to the one from Al-BSF in Figure 4; note the different y-axis scaling.
