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

Figure 4

The time dependence of efficiency versus the initial value of the PERC solar cells before and after regeneration by using 10 A injection current at 180°C for different times (0, 2, 5, 10, 20, and 30 min) and during the subsequent 12 h LID.
