摘要
为提升光伏组件封装环节的光线利用率,围绕光伏玻璃减反射镀膜工艺展开了研究,系统分析了主流镀膜方法,明确膜层折射率接近1.25时可实现最优光学增益。研究从镀膜液配方设计入手,通过构建核壳结构调控孔隙率以降低折射率;在工艺过程中,协调流平与干燥动力学,控制温湿度、基板粗糙度与膜厚均匀性,避免膜层缺陷;并优化钢化工艺以维持孔隙结构。实验结果表明,上述措施可显著提高380~1100 nm波段的平均透过率,接近理论极限。为高性能光伏玻璃镀膜生产提供了关键质量控制依据。
To improve light utilization in photovoltaic module encapsulation,this study investigates anti-reflection coating processes for photovoltaic glass.We systematically analyze mainstream coating methods and determine that a coating refractive index approaching 1.25 achieves optimal optical gain.Starting with coating solution formulation,a core–shell structure is constructed to regulate porosity and reduce refractive index.During coating,leveling and drying kinetics are balanced,while temperature,humidity,substrate roughness,and film thickness uniformity are controlled to prevent defects.The tempering process is also optimized to preserve pore structure.Experimental results show that these measures significantly enhance the average transmittance in the 380~1100 nm range,approaching the theoretical limit.This study provides key quality control guidelines for producing high-performance coated photovoltaic glass.
