Physical Nature of PID-s

In the field a large potential between the front glass surface and the solar cells in a module can occur and a shunting of the p-n junction of a Si solar cell and accordingly a decrease in…

Comparison of PID Test Methods

The PIDcon test has the following advantages compared to other methods:Short duration (usually 4–8h), High variability: test of solar cell, mini-module, glass and EVA, Good control of test…

Conductance Test and Power Loss

Furthermore an easy pass or fail criterion after finishing the PID measurement is suggested. It is assumed that an efficiency loss of 3% at the end of the PID test lead to a fail of the solar…
