The obtained results indicate that leakage current is not only related with electrical layout of the PV array but also the resistance of EVA and glass. Need Help?
Abstract: In photovoltaic power station, the solar cells in the module are exposed to positive or negative bias, which will lead to leakage current between the frame and solar cells.
The system voltage of solar panels drives a leakage current between the solar cells and the grounded metal frames. This results in many different forms of potential induced degradation, including shunting, polarization, 1 delamination, and corrosion.
The leakage current pathway from the glass/polymer interface has the least resistance providing a negative current. Similarly, the charge at the AR coating to polymer interface, QAR, is also flowing out through the metallization but in this case contributes as a positive current because of the instrument configuration.
