Abstract

Abstract: We try to find a fast and simple potential induced degradation effect (PID) test procedure for crystalline silicon solar cells. With sodium chloride (NaCl) solution as Na + source, PVB as lamination material, we can carry out the test in 1 h. Solar cells with newly developed PID resistance process were also tested. The increase of reverse current of solar cell 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.
