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

Figure 1

The variation of efficiency relative to the initial value of the PERC solar cells with time which were regenerated by using 10 A injection current at different temperatures (160, 180, 200, 220, 240, and 260°C) for 30 min before and after regeneration and during the subsequent 12 h LID.
