摘　　要：针对海上光伏玻璃所面临的腐蚀环境,为提高光伏玻璃综合性能,试验以纳米二氧化钛、调墨油、玻璃粉和中空二氧化硅微球制备釉料,进而制备一种涂覆釉层的光伏背板玻璃,并探讨其光反射性能以及耐腐蚀性能。研究结果表明,当釉层中的纳米二氧化钛掺量为40%、釉层厚度为18μm时,光伏背板玻璃综合性能最佳。此时材料反射率达到84.89%,在盐酸溶液、氢氧化钠溶液以及氯化钠溶液中浸泡10 h后依然有较高的反射率,耐酸性、耐碱性以及耐盐性优异,可以有效提高海上光伏转换率。In view of the corrosive environment faced by offshore photovoltaic glass,in order to improve the comprehensive performance of photovoltaic glass,a glaze was prepared by nano titanium dioxide,ink oil,glass powder and hollow silica microspheres,and then a photovoltaic backsheet glass coated with glaze layer was prepared,and its light reflection performance and corrosion resistance were discussed.The results showed that when the nano-titanium dioxide content in the glaze layer was 40%and the glaze thickness was 18μm,the comprehensive performance of photovoltaic backsheet glass was the best.At this time,the reflectivity of the material reached 84.89%,and it still had high reflectivity after soaking in hydrochloric acid solution,sodium hydroxide solution and sodium chloride solution for 10 h,and had excellent acid,alkali and salt resistance,which could effectively improve the conversion rate of offshore photovoltaics.
