光伏技术是可再生能源的重要来源，但由于其巨大的能量转换面积，大型光伏设备的维护成本和效率衰减是一个重大问题。为了降低成本并方便维护，人们开发了具有自清洁特性的超疏水表面用于光伏玻璃。本研究在光伏玻璃上合成了透明ZnO纳米阵列（NAs），Eu ³⁺掺杂增强了光伏器件的抗紫外线辐射能力，并略微提高了可见光透过率。_二氧化钛在 ZnO NAs 表面引入钝化层，以增强耐酸性并减轻酸性雨水引起的腐蚀。氟烷基硅烷（POTS）改性实现了超疏水性，水接触角为160.25°，液滴滚动实验证明。通过原子力显微镜力曲线测量进一步研究了超疏水性能的微观相互作用，结果显示超疏水表面几乎没有纳米水份，但对照玻璃表面有明显的水份。最后，使用该自清洁玻璃制造的模拟模型和实际硅晶太阳能电池表现出优异的耐酸雨、自清洁和长使用寿命特性，在40天的户外应用测试中，功率转换效率没有下降。

TiO2 Passivated Zno Nanoarray Layer Based Fluoroalkylsilane Film for Photovoltaic Optical Glass: Achieving UV Shielding, Acid Rain Resistance, and Self-Cleaning Properties

Photovoltaic technology is a prominent source of renewable energy, but maintenance costs and efficiency attenuation of large photovoltaic devices are significant issues due to their vast energy conversion area. To reduce costs and facilitate maintenance, superhydrophobic surfaces with self-cleaning properties have been developed for photovoltaic glass. In this study, transparent ZnO nanoarrays (NAs) are synthesized on photovoltaic glass, with Eu³⁺ doping enhancing the ultraviolet radiation resistance of photovoltaic devices and slightly increasing visible transmittance. A TiO₂ passivation layer is introduced on the ZnO NAs surface to enhance acid resistance and mitigate corrosion caused by acidic rainwater. Fluoroalkylsilane (POTS) modification achieves superhydrophobicity with a water contact angle of 160.25°, as demonstrated by droplet rolling experiments. Micro-interaction of superhydrophobic properties is further investigated by force curve measurement using atomic force microscope, showing almost no nanometer water moisture on the superhydrophobic surface, but conspicuous water moisture on the control glass surface. Finally, simulated models and practical silicon crystal solar cells fabricated using the self-cleaning glass show excellent acid rain resistance, self-cleaning, and long service life properties, with no power conversion efficiency degeneration during a 40-day outdoor application test.
