Self-cleaning mechanisms of photovoltaic panels is a research hotspot in recent years, but the preparation of superhydrophobic coatings with excellent anti-reflection effect and durability for photovoltaic panels is still a problem to be solved. Inspired by the human scalp structure, we propose an interconnected three layer coatings (ITSC), which can produce self-cleaning effect on photovoltaic panels. Specifically, the prepared ITSC, owning porous three-dimensional network structure, consists of three layers with similar and cross-linked materials to ensure continuity and good adhesion among layers. Based on the experimental results, it can be concluded that the coating has an average transmittance that is 6.44% higher compared with bare glass. The bandwidth of high light transmittance (>91%) is almost 4 times that of bare glass. The pencil hardness test grade of the coating is 5 H, and the tape adhesion test grade is 5 B. In three simulated severe environmental stability tests (acid rain, high temperature and low temperature), the proposed coating can still maintain long term superhydrophobicity. Compared with uncoated photovoltaic panels, the maximum output power of coated one is 2.61 times that of the blank panel after the deposition of saline laterite under simulated drizzle conditions. The proposed coatings provide a promising solution for improving the performance of photovoltaic panels, reducing the negative impact of dust deposition, and improving the power output efficiency of photovoltaic power plants.

光伏板的自清洁机制是近年来的研究热点，但是为光伏板制备具有优异增透效果和耐久性的超疏水涂层仍然是一个有待解决的问题。受人体头皮结构的启发，我们提出了一种互连的三层涂层（ITSC），它可以在光伏板上产生自清洁效果。具体而言，所制备的ITSC具有多孔三维网络结构，由三层相似且交联的材料组成，以确保层与层之间的连续性和良好的粘附性。根据实验结果，可以得出结论，涂层的平均透光率比裸玻璃高 6.44%。高透光率（>91%）的带宽几乎是裸玻璃的4倍。该涂层的铅笔硬度测试等级为5H，胶带附着力测试等级为5B。在三个模拟的严酷环境稳定性测试（酸雨、高温和低温）中，该涂层仍能保持长期的超疏水性。与未镀膜的光伏电池板相比，在模拟毛毛雨条件下，经过盐渍红土沉积后，镀膜电池板的最大输出功率是空白电池板的 2.61 倍。拟议的涂料为提高光伏电池板的性能、减少灰尘沉积的负面影响以及提高光伏电站的功率输出效率提供了一种有前途的解决方案。高温和低温），所提出的涂层仍然可以保持长期的超疏水性。与未镀膜的光伏电池板相比，在模拟毛毛雨条件下，经过盐渍红土沉积后，镀膜电池板的最大输出功率是空白电池板的 2.61 倍。拟议的涂料为提高光伏电池板的性能、减少灰尘沉积的负面影响以及提高光伏电站的功率输出效率提供了一种有前途的解决方案。高温和低温），所提出的涂层仍然可以保持长期的超疏水性。与未镀膜的光伏电池板相比，在模拟毛毛雨条件下，经过盐渍红土沉积后，镀膜电池板的最大输出功率是空白电池板的 2.61 倍。拟议的涂料为提高光伏电池板的性能、减少灰尘沉积的负面影响以及提高光伏电站的功率输出效率提供了一种有前途的解决方案。
