4. PID solutions
The mechanism of potential-induced degradation has yet to be fully clarified. However, solutions are available to prevent the PID effect at all three levels: cell, module and power plant.
4.1 At the cell level
At this stage, the main method for preventing PID is to modify the anti-reflective coating, whose presence increases light absorption. The key is to find the right compromise between the thickness of the anti-reflective coating and the refractive index. The phenomenon can be eliminated by increasing the refractive index, but this will have an impact on the efficiency of the
