Study on the Electrical Injection Regeneration of Industrialized B-Doped Czochralski Silicon PERC Solar Cells

Figure 7

The time dependence of - characteristic parameters of the PERC solar cells versus the initial values regenerated by using different injection currents (6, 8, 10, 12, 14, 16, and 18 A) at 180°C for 30 min before and after regeneration and during the subsequent 12 h LID: (a) ; (b) ; (c) ; (d) .
