Hydrophobic Single‐Walled Carbon Nanotube‐Nanosilicon Dioxide Transparent Conductive Film and Its Application in Photovoltaic Dust Removal

Year: 2026

Type: article

Abstract: The inevitable accumulation of dust on photovoltaic (PV) panel surfaces severely affects the solar energy conversion rate. In recent years, electrostatic adsorption dedusting based on transparent electrodes has become a popular research topic in the PV field, and transparent conductive film (TCF) materials with self‐cleaning properties have become the preferred solution for PV dust removal. This article presents a hybrid method combining electrostatic adsorption dedusting with superhydrophobic coating to prepare a hydrophobic multifunctional single‐walled carbon nanotube‐nanosilicon dioxide (SWCNT‐SiO 2 ) TCF. The results showed that the index K A is 0.90, the light transmittance is 91.44%, and the sheet resistance is 41.80 kΩ/sq when the sol mass fraction of SWCNTs‐SiO 2 TCFs is 10 wt%. After electrostatic adsorption dedusting tests based on these TCFs, most of the dust was removed, and the conversion efficiency of the PV panels increased to 95.13% of that in a clean state. Simultaneously, the water contact angle reaches a maximum of 150.11°, showing superhydrophobicity, and the self‐cleaning rate reaches 93.05% under laboratory simulation conditions. This study is expected to support the optimization and innovation of PV panel dust removal methods and the further development of the PV industry.
