基于透明导电薄膜的静电除尘方法近年来已成为光伏板除尘领域的研究热点,除尘效果与透明导电薄膜的性能紧密相关。针对光伏板静电除尘技术的应用需求,以环氧树脂(epoxy resin,EP)为基体,制备得到导电填料为纳米银线(silver nanowires,AgNWs)的透明导电薄膜,并基于制备得到的纳米银线-环氧树脂(AgNWs-EP)透明导电薄膜进行光伏板静电除尘实验。结果表明,静电除尘率随着AgNWs质量份比例增大而升高,在AgNWs的质量份为80000 phr时,除尘率最大可达到95.67%,光伏板的发电效率可相对提升40.84%。此时,薄膜的方阻为10^(7)Ω/□,除尘适用性指标为0.42。600 h人工加速紫外老化和机械耐久性测试表明,薄膜具有优异的耐老化特性。研究结果对于拓展AgNWs-EP透明导电薄膜的应用场景、推动基于透明导电薄膜的光伏板静电除尘技术的发展具有重要意义。

Electrostatic dust removal technology based on transparent conductive film is becoming a research hotspot in the field of photovoltaic panel dust removal in recent years,and the dust removal effect is closely related to the performance of transparent conductive film.In order to meet the application requirements of photovoltaic panel electrostatic dust removal technology,transparent conductive thin films with conductive fillers of silver nanowires(AgNWs)are prepared by using epoxy resin(EP)as substrate.Based on the prepared AgNWs-EP transparent conductive films,photovoltaic panel electrostatic dust removal experiments are carried out.The experimental results show that the electrostatic dust removal rate increases with the increase of the AgNWs parts per hundred parts of resin.When the AgNWs parts per hundred parts of resin is 80000 phr,the dust removal rate can reach 95.67%,and the photovoltaic panel power generation efficiency can be relatively increased by 40.84%.Under this condition,the square resistance is 10^(7)Ω/□,and the dust removal applicability index is 0.42.The results of the 600 h artificial ultraviolet aging test and mechanical durability test show that the film has excellent aging resistance.The research results are of great significance for expanding the application scene of AgNWs-EP transparent conductive film and promoting the development of photovoltaic panel electrostatic dust removal technology.
