太阳能作为一种清洁可再生能源，为缓解全球能源危机而备受关注。太阳能光伏发电系统是收集太阳能的一种可靠方式，但由于电老化引起的累积电荷退化，太阳能的使用寿命通常会短于设计时间。随着光伏系统的快速发展，传统的聚对苯二甲酸乙二醇酯(PET)背板已不能满足先进太阳能系统对绝缘和封装的要求。在此背景下，选择了两种不同的背板材料，即KPK(聚偏氟乙烯，PET，聚偏氟乙烯)和TPT(聚偏氟乙烯，PET，PVF)，以探讨局部放电和电晕放电引起的累积电荷诱导降解。通过局部放电对背板施加30、60和120min的电应力，通过电晕放电对背板施加10min的电应力。用相分辨局部放电(PRPD)和表面电位衰减(SPD)研究了电荷的积累和输运。同时，用原子力显微镜研究了Pd活化后KPK和TPT的表面形貌。对Pd活性的研究表明，KPK和TPT具有相似的Pd电阻，但在电晕放电后，它们的SPD完全不同。本文的研究工作为研究聚合物绝缘老化过程、评估光伏组件绝缘背板寿命提供了重要途径，对提高光伏系统检测标准具有一定的指导意义。
As a clean and renewable energy, solar energy has drawn people's attention to mitigate the energy crisis around the world. A solar photovoltaic (PV) system is a reliable way to collect solar energy whose service lifetime is usually shorter than the designed time because of accumulated charge-induced degradation caused by electrical aging. With the rapid development of PV systems, the traditional polyethylene terephthalate (PET) backsheet cannot meet the requirements of insulation and package for the advanced solar energy system. In this context, two different backsheet materials, namely, KPK (polyvinylidene fluoride, PET, polyvinylidene fluoride) and TPT (polyvinyl fluoride, PET, polyvinyl fluoride), were selected to explore accumulated charge-induced degradation caused by partial discharge (PD) and corona discharge. In this paper, the backsheets were electrically stressed for 30, 60, and 120 min by PD and electrically stressed for 10 min by corona discharge. The accumulation and transportation of charges were investigated by phase-resolved partial discharge (PRPD) and surface potential decay (SPD). At the same time, the topography of KPK and TPT determined using atomic force microscopy after PD activity was also investigated. The explorations of PD activity showed that KPK and TPT have a similar PD resistance, but their SPD were entirely different after corona discharge. The research works in this paper provide an important path to investigate the aging process of insulating polymers and evaluate the lifetime of insulating backsheets of PV modules, as well as a guidance to improve the testing standards for the PV system.
