首先对比研究4种国产低温PVDF氟膜和进口PVF氟膜的耐低温性能、耐高温高湿性能、耐高低温性能、耐湿冻性能和耐紫外性能,然后研究对应氟膜背板的耐高温高湿性能、耐高低温耐湿冻性能和耐紫外性能,最后深入研究不同氟膜背板组件的综合序列老化性能。结果表明,某些国产PVDF低温氟膜的耐老化水平已达到PVF氟膜水平,PVDF低温氟膜制成的KPC背板也具有优异的耐老化性能;某些国产PVDF低温氟膜背板组件的综合耐老化性能甚至优于进口PVF氟膜背板组件,可满足光伏组件户外25 a以上的发电使用寿命。
Abstract
Firstly, different aging experiments were employed to evaluate the aging properties of four kinds of Chinese-made low temperature resistant PVDF films and one kind of imported PVF film, including low temperature aging （-40 ℃,30 min）, hygrothermal aging （DH2000 h）, high temperature and high humidity aging （PCT96 h）, high and low temperature cycle aging （TC600）, high and low temperature cycle with moisture aging （HF20）, and UV resistant （UV250 kWh/m; 2）. Secondly, the aging performance of the related low temperature resistant PVDF film back-sheets （KPC） were investigated for PCT48 h, TC50+HF10 and UV250 kWh/m; 2 tests. Finally, the KPC back-sheets composed of usual PVDF films, low temperature resistant film and PVF film were used to make up photovoltaic modules, and the comprehensive aging performances are deeply researched under different conditions. The results indicate that the aging resistant level of some Chinese-made low temperature resistant PVDF films has reached that of the imported PVF film. The KPC backsheets with low temperature resistant PVDF films exhibited anti-aging ability. Some PV modules with low temperature resistant PVDF film KPC backsheets have showed a significant advantage over those with TPC backsheets.
