摘　　要：文章通过实验研究了全氟溴化季铵盐作为新型疏水材料在光伏板表面的应用优化情况。首先,将全氟溴化季铵盐采用一定比例配制该疏水材料,对其抗菌性能进行了实验评估。通过视频光学接触角测量仪,评估了涂覆薄膜后光伏玻璃面板的接触角,结果显示水滴接触角超过100°,表明材料具备优异的疏水性及自清洁特性。其次,对涂膜后的光老化及莫氏硬度进行测量,结果表明涂膜后光老化保持稳定,莫氏硬度提高了1级。通过分光光度计测定薄膜的透光率和折射率,发现涂层显著提高了光伏玻璃的透光性能。最后,通过对不同区域电站的光伏面板进行比较,结果显示涂覆疏水涂层后,发电量最高提升14.6%,同时维持了良好的发电效率。这些结果表明,全氟溴化季铵盐作为疏水材料在提高光伏发电效率及延长设备寿命方面具有显著应用潜力。This study experimentally investigates the application and optimization of perfluorobrominated quaternary ammonium salt as a novel hydrophobic material on the surface of photovoltaic panels.Initially,the hydrophobic material was formulated at a specific ratio,and its antibacterial performance was evaluated.Utilizing a video optical contact angle measuring device,the contact angle of the coated photovoltaic glass panels was assessed,revealing that the water droplet contact angle exceeded 100°,indicating excellent hydrophobicity and self-cleaning properties of the material.Furthermore,the effects of the coating on photodegradation and Mohs hardness were measured,showing that photodegradation remained stable after coating,while Mohs hardness increased by one level.Spectrophotometric measurements of the film’s transmittance and refractive index indicated a significant improvement in the light transmittance of the photovoltaic glass.Finally,comparative analysis of photovoltaic panels across different regions demonstrated that the application of the hydrophobic coating resulted in a maximum increase in power generation of 14.6%,while maintaining good energy efficiency.These findings suggest that perfluorobrominated quaternary ammonium salt has significant potential for enhancing photovoltaic efficiency and prolonging the lifespan of solar energy devices.
