随着国内外前期投资的光伏电站的陆续并网发电并运行，国内外电站的质量问题大规模出现。许多电站爆发出了蜗牛纹、PID衰减等的品质问题。该问题引发了国内外对电站品质的高度关注。由于有机材料的寿命短、耐候性差，光伏组件中的EVA胶膜和背板的质量开始被高度关注。一些国内电站由于使用了劣质的EVA胶膜导致70％的组件发生大规模的蜗牛纹问题，还有的电站在运行一年左右就发现了高达60％的衰减。As the photovoltaic power plants invested in the early stage at home and abroad are connected to the grid for power generation and operation, the quality problems of domestic and foreign power plants have appeared on a large scale. Quality problems such as snail pattern and PID attenuation broke out in many power stations. This problem has aroused great concern at home and abroad for the quality of power plants. Due to the short life and poor weather resistance of organic materials, the quality of EVA film and backsheet in photovoltaic modules has begun to be highly concerned. Some domestic power stations use low-quality EVA film, causing large-scale snail pattern problems in 70% of the modules, and some power stations have found up to 60% attenuation in about a year of operation.
这些问题除了野蛮施工外，往往和水汽穿透背板导致劣质EVA树脂快速降解有密切的关系。EVA树脂遇水即开始分解，其分解产物含醋酸，醋酸腐蚀光伏电池上的银栅线、汇流带等，使组件的发电效率逐年下降。一些近水的光伏发电项目，比如鱼光互补、滩涂电站、农业温室以及早晚露水大的地区的光伏项目很快就成了高危项目。由于目前电站持有方按度电计算投资回报率，所以组件的长期可靠性、耐候性成为光伏组件厂首先需要考虑的性能指标。In addition to brutal construction, these problems are often closely related to the rapid degradation of inferior EVA resin caused by water vapor penetrating the backsheet. EVA resin begins to decompose when it encounters water, and its decomposition product contains acetic acid, which corrodes the silver grid lines and busbars on the photovoltaic cell, which reduces the power generation efficiency of the module year by year. Some photovoltaic power generation projects near water, such as fish-photovoltaic complementation, tidal flat power stations, agricultural greenhouses, and photovoltaic projects in areas with heavy dew in the morning and evening quickly become high-risk projects. Since the current power station owner calculates the return on investment by kWh, the long-term reliability and weather resistance of the modules have become the first performance indicators that photovoltaic module manufacturers need to consider.
公告号为CN105802548B的中国发明专利中提出了一种用于双波光伏组件的白色EVA封装胶膜，具有优异的韧性，高的反光率及体积电阻率。公布号为CN106634647A的中国发明专利申请公开了一种阻燃型白色EVA封装胶膜。这些材料并没有解决太阳能组件在长期使用中的耐候、耐紫外、耐高低温性能，长期使用后会出现蜗牛纹和PID衰减问题。The Chinese invention patent with the announcement number CN105802548B proposes a white EVA encapsulation film for dual-wave photovoltaic modules, which has excellent toughness, high light reflectivity and volume resistivity. The Chinese invention patent application with publication number CN106634647A discloses a flame-retardant white EVA encapsulation film. These materials do not solve the weather resistance, UV resistance, high and low temperature resistance of solar modules in long-term use, and snail patterns and PID attenuation problems will occur after long-term use.
综合来看，现有EVA胶膜存在老化性能差、水蒸气透过率高以及遇水会快速降解等缺点，导致双玻光伏组件的PID96衰减较大，使用寿命有待提高。On the whole, the existing EVA film has shortcomings such as poor aging performance, high water vapor transmission rate, and rapid degradation in contact with water, resulting in a large attenuation of PID96 of double-glass photovoltaic modules, and the service life needs to be improved.
