This effect may cause power loss of up to 30 percent.〔(Fraunhofer CSP presents results of potential induced degradation (PID) ) Fraunhofer Center for Silicon Photovoltaics CSP〕 The cause of the harmful leakage currents, besides the structure of the solar cell, is the voltage of the individual photovoltaic (PV) modules to the ground. In most ungrounded PV systems, the PV modules with a positive or negative voltage to the ground are exposed to PID. PID occurs mostly at negative voltage with respect to the ground potential and is accelerated by high system voltages, high temperatures, and high humidity. ==History== The term Potential–Induced Degradation (PID) was first introduced in the English language in a published study by S. Pingel and coworkers in 2010.〔Proceedings of the 35th IEEE PVSC 20–25 June 2010 pp. 2817-2822〕 It was introduced as a degradation mode resulting from voltage potential between the cells in the photovoltaic module and ground. Research in this field was pioneered by the Jet Propulsion Laboratory, focusing primarily on electrochemical degradation in crystalline silicon 〔http://www2.jpl.nasa.gov/adv_tech/photovol/ppr_81-85/Pred%20Electrochem%20Breakdown%20-%20PVSC1984.pdf〕 and amorphous silicon〔http://www2.jpl.nasa.gov/adv_tech/photovol/ppr_81-85/Elechem%20Degr%20of%20a-Si%20Modules%20-%20PVSC1985.pdf〕 photovoltaic modules. The degradation mechanism known as polarization found in the first generation crystalline silicon high performance modules from SunPower in strings having positive voltage potential with respect to ground was discussed in 2005.〔R. Swanson et.al. 15th PVSEC, Shanghai (2005)〕 Degradation of conventional front junction (n+/p) solar cell modules under voltage potential was also observed. The degradation by polarization was also covered in the trade journal Photon (4/2006, 6/2006, and 4/2007). In 2007, PID was reported in a number of solar panels from Evergreen Solar (Photon 1/2008 and 8 /2008). In this case, the degradation mechanism occurring in photovoltaic modules containing the more common front junction (n+/p) crystalline silicon solar cells when the modules were in negative voltage potential with respect to ground. PID was further discussed as a problem in ordinary crystalline modules (Photon 12/2010, lecture by solar energy company Solon SE at PVSEC in Valencia 2010). Statement of the solar module manufacturer Solon SE: ''"At 1000 V , a now quite common voltage for larger PV systems, it can be critical for each module technology"''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Potential induced degradation」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
