围绕气候变化和环境污染，可再生能源的开发和应用日益受到关注，特别是太阳能。然而，光伏组件容易受到紫外线（UV）照射和电场的影响，导致光伏组件的实际使用寿命减少。在此，研究了PV绝缘封装材料在UV照射后的电老化特性。分别通过光学显微镜、原子力显微镜（AFM）和红外光谱观察了紫外线照射和局部放电（PD）后聚酰亚胺（PI）基材表面形貌和官能团的变化。从结果来看，与未处理的PI相比，UV照射96 h后的PI表面形貌和分子结构都有轻微变化；同时，放电10小时后，与紫外照射后的PI相比，PI的平均表面粗糙度（Ra）从1.89 nm增加到114 nm，并出现了2981 cm−1左右的–CH3。这些研究结果为评估光伏封装材料的降解性能提供了重要信息，甚至为开发性能优异的光伏封装材料提供了重要参考。
Focusing on the climate change and environmental pollution, the development and application of renewable energy increasingly obtain more attentions, particularly in solar energy. Nevertheless, PV modules are susceptible to ultraviolet (UV) irradiation and electric field, which cause the decrease of the actual service time of PV modules. Here, the electrical aging characteristics of PV insulating encapsulant after UV irradiation are studied. The changes in the surface morphology and functional groups of polyimides (PI) substrate after UV irradiation and partial discharge (PD) are observed by optical microscopy, atomic force microscopy (AFM), and infrared spectrum, respectively. From the results, compared with the untreated PI, surface topography and molecular structure of PI after UV irradiation for 96 hours have slight change; meanwhile, after discharge for 10 hours, the average surface roughness (Ra) of PI increases from 1.89 nm to 114 nm compared with the PI after UV irradiation, and – CH3 around 2981 cm−1 has emerged. These findings provide significant information for evaluating the degradation performance of PV encapsulant, and even provide important reference to develop PV encapsulant with excellent performance.
