Effective lifetime τeff (top), lifetime equivalent defect density ΔNleq (middle) and change in surface-related saturation density Δj0 (bottom) versus accumulated treatment time for differently processed n-type FZ samples. Samples were degraded at 0.9(1)suns photon flux equivalent and a temperature of 100 °C. The lines in the graphs are guide-to-the-eye.
