potential induced degradation（PID） has become one of the main factors that reduce the output power of PV *** are easy to be affected by PID if the PV system operates under a humid environment. PV modules in a mountain PV power station under warm temperate climate in China were tested to study the occurrence regularity of PID and its effect on the electrical performance of PV strings. The test items include power degradation test, Electroluminescent（EL） test, Infrared Radiation（IR） test and series connection mismatch loss test of PV module. The power recovery method for PV modules affected by PID was also researched in this paper. Test results shows that the power of PV modules affected by PID can decrease seriously. In the environmental chamber with high temperature and humidity condition, power loss of PV modules affected by PID can recovery with a positive bias voltage stress.

Polarization effects and tests for crystalline silicon solar cells

引用

Journal of Semiconductors 2015年第9期36卷 9-14页

We try to find a fast and simple potential induced degradation effect （PID） test procedure for crystalline silicon solar cells. With sodium chloride （NaC1） 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.
