Abstract

The efficiency of photovoltaic (PV) systems is significantly hindered by soiling, especially in desert climates where dust accumulation on PV surfaces is prevalent and reduces light transmission and increases maintenance costs. This study provides a comprehensive review of anti-soiling and anti-reflective coatings (ASC & ARC) designed to mitigate these effects and enhance PV performance. The review examines various coating materials, synthesis techniques such as (Sol-gel, Magnetron sputtering, spray pyrolysis), and surface properties, emphasizing their optical performance, durability, and outdoor reliability in harsh environments. Laboratory characterization methods, including UV–Vis spectroscopy, SEM, AFM, and contact angle measurements, are analyzed alongside real-world field studies. The study also integrates standardized testing frameworks (IEC and ASTM protocols) to evaluate coatings under extreme environmental conditions such as UV exposure, thermal cycling, and mechanical abrasion. Results highlight that optimized coatings can significantly reduce soiling rates, improve light absorption, and enhance long-term energy yield. Furthermore, combining ASC and ARC functionalities has shown potential for maximizing PV efficiency while minimizing cleaning requirements. This review serves as a critical reference for advancing coating technologies, bridging the gap between laboratory research and large-scale PV deployment, and guiding the development of durable, cost-effective solutions for desert climates.
沙漠气候下光伏系统防污防反射涂层的性能和耐久性
光伏(PV)系统的效率受到污染的严重阻碍,特别是在沙漠气候中,光伏表面的灰尘积聚普遍存在,减少了光的传输并增加了维护成本。本文综述了防污防反射涂料(ASC &;ARC)旨在减轻这些影响并提高PV性能。该综述考察了各种涂层材料、合成技术(如溶胶-凝胶、磁控溅射、喷雾热解)和表面性能,强调了它们的光学性能、耐久性和恶劣环境下的室外可靠性。实验室表征方法,包括紫外可见光谱,扫描电镜,原子力显微镜和接触角测量,分析与现实世界的实地研究。该研究还集成了标准化测试框架(IEC和ASTM协议),以评估极端环境条件下的涂层,如紫外线暴露、热循环和机械磨损。结果表明,优化后的涂层可以显著降低污染率,改善光吸收,提高长期能源产量。此外,结合ASC和ARC功能可以最大限度地提高光伏效率,同时最大限度地减少清洁要求。这一综述为推进涂层技术、弥合实验室研究与大规模光伏部署之间的差距、指导沙漠气候下耐用、经济的解决方案的发展提供了重要参考。
