Abstract: We try to find a fast and simple potential induced degradation effect (PID) test procedure for solar cells. With sodium chloride (NaCl) solution as Na+ source, PVB as lamination material, we can carry out the test for solar cells in 1 h. Solar cells with newly developed PID resistance process were also tested. The increase of reverse current of solar cells can be considered a key standard to determine if the solar cell was prone to PID. Moreover, it showed that the increase of reverse current for the PID resistance solar cell was less than 2. In addition, the test results of the solar cells fitted very well with that of the modules by standard procedure.

Fig1.  Schematic test setup with two-EVA laminates and a crystalline silicon cell in between. The outside surface of the front EVA has been equipped with copper foil. The foil and the cell's contacts have been connected to a laboratory DC power supply and have been stressed with a voltage of $-600$~V at 85 $^\circ C$ at 85% RH.
