(a) Histograms of damage current density in dark reverse bias sweeps with on the left results of fixed current range and on the right the auto-change current range results. The last bin (bottom) represents the number of cells with a damage current density smaller than −22.5 mA/cm². (b) Histograms of damage voltage in dark reverse bias sweep and the normal distribution curve based on average and standard deviation for measurements performed with fixed and auto-change current range.
