Antireflection coatings (ARCs) on an optical substrate appear to be highly effective for reducing reflectance for optical and photovoltaic (PV) panel applications. In this perspective, we have prepared and investigated the performance of silica nanoparticles (SNPs) ARC through a sol–gel process for the PV module applications. The ∼160-nm-thick sol–gel prepared SNPs have been coated on a glass substrate using the spin coating technique. The further vapor-phase treatment of hexamethyldisilazane (HMDS) on silica-coated glass results in contamination-resistant due to the existence of trimethylsilyl groups. The resultant-coated glass exhibits improvement in transmission by ∼3 % while reducing the refractive index value up to 1.17. The solar cell tested undercoated glass notifies the increase in current density of 34.24 to 35.17 mA / cm2 and improves the overall efficiency up to 3.13% as compared to the untreated glass. The results obtained in our study suggest an important future direction for the use of HMDS-treated SNPs in an outdoor PV module and solar collector applications.

疏水性二氧化硅纳米粒子作为玻璃上的减反射涂层的光学性能得到改善，并且其在光伏模块应用中的电性能

光学基板上的抗反射涂层（ARC）似乎对于降低光学和光伏（PV）面板应用的反射率非常有效。从这个角度出发，我们通过溶胶-凝胶工艺制备并研究了用于光伏组件应用的二氧化硅纳米粒子（SNP）ARC的性能。使用旋涂技术将厚度约160 nm的溶胶凝胶制备的SNP涂覆在玻璃基板上。由于三甲基甲硅烷基的存在，在涂有二氧化硅的玻璃上对六甲基二硅氮烷（HMDS）进行进一步的气相处理会导致抗污染。所得镀膜玻璃的透射率提高了约3％，同时将折射率值降低到1.17。经过太阳能电池测试的未镀膜玻璃通知电流密度从34.24增加到35。与未处理的玻璃相比，它可达到17 mA / cm2的电流，并且可将整体效率提高至3.13％。在我们的研究中获得的结果表明，在室外PV组件和太阳能收集器应用中使用经HMDS处理的SNP的重要未来方向。
