Potential Induced Degradation (PID) causes major reliability issues, since it results in significant performance degradation and negatively affects the durability of cells, modules and PV systems. In this work three ...

Potential induced degradation (PID) is a defect that has a severe effect on the performance of photovoltaic (PV) modules in field conditions. It is caused by leakage currents and the accumulation of sodium ions (Na+) between ...
