PID-Technik

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…

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…

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…
