摘　　要：在全球气候变暖及化石能源日益枯竭的大背景下,太阳能的开发利用日益受到国际社会的重视.然而,太阳能发电板多在户外使用,自然环境中粉尘等微颗粒的沉积现象极易发生,已成为影响光伏组件光电转换效率的重要因素.本研究通过溶胶-凝胶法制备了SiO_(2)纳米颗粒,并进一步制备了超亲水抗静电自清洁涂层(HAC).在此基础上,探究了SiO_(2)纳米颗粒粒径和含量对涂层表面微纳凹凸结构的影响,阐明了SiO_(2)纳米溶胶与自清洁涂层润湿性的关联.本文制备的自清洁涂层兼具良好的超亲水性和抗静电性能,能够有效提升光伏玻璃表面的防尘防污能力;同时,HAC还能够在一定程度上增加太阳光的透射率,从而进一步提高发电效率,在提升光伏组件防污自清洁及发电量提升方面展现出了巨大的应用潜力.Against the background of global climate change and the increasing depletion of fossil energy,the development and utilization of solar energy is receiving increasing attention from the international community.However,solar panels are mostly used outdoors,where the deposition of dust and other particulates in the natural environment easily occurs,which has become an important factor affecting the photoelectric conversion efficiency of photovoltaic components.Herein,SiO_(2)nanoparticles were prepared by sol-gel method,and a superhydrophilic,anti-static self-cleaning coating(HAC)was further prepared.Based on this,the effect of SiO_(2)nanoparticle size and content on the surface micro-nanostructure of the coating was investigated,elucidating the relationship between SiO_(2)nanoparticle sol-gel and the wettability of the self-cleaning coating.The selfcleaning coating prepared in this study possesses both excellent superhydrophilic and anti-static properties,effectively enhancing the dust and dirt resistance of the photovoltaic glass surface.At the same time,HAC can also increase the transmittance of sunlight to a certain extent,so as to further improve the efficiency of power generation,demonstrating significant potential in enhancing the anti-soiling self-cleaning ability and power generation of photovoltaic components.
