Polarization-type potential-induced degradation in bifacial perc modules in the field

HIGHLIGHTS

• What: This study examines the susceptibility of bifacial glass/glass passivated emitter and rear cell (PERC) modules to potential-induced degradation-polarization (PID-p) in the field. The authors examine the effects of mounting configuration; specifically, comparing modules mounted near ground and in elevated ground rack configurations. The authors first evaluated commercial 420 W (nominal) bifacial glass/glass PERC modules with ethylene vinyl acetate (EVA) encapsulant for PID-p sensitivity with both positive and negative 1500 V applied to the cell circuit at 25 °C for 168 h in an environmental chamber according to method (b), the . . .
