Maintaining solar cell efficiency realized by high-transparency dual-function SiO2 coating with self-cleaning and dust removal
Addressing the issue of dust deposition on photovoltaic (PV) panels is of profound scientific significance and practical value for enhancing PV power generation. Transparent superhydrophobic coating is expected to be applied in the self-cleaning of PV panels. However, developing the transparent superhydrophobic dust removal coatings remains a challenge. Herein, we developed a highly transparent F-SiO2 coating with dual self-cleaning and dust removal functions, composed of polydimethylsiloxane (PDMS) and SiO2. The coating demonstrates a high transmittance of 97 %. After self-cleaning and dust removal tests, conversion efficiency of F-SiO2 coated PV decreased by only 0.03 % and 0.01 %, respectively, demonstrating excellent self-cleaning and dust removal performance. Additionally, the F-SiO2 exhibits high stability. Mechanism analysis of dust removal performance reveals that the decreased effective dielectric constant from the porous structure and the reduced actual contact area between the particles and the superhydrophobic surface, thereby effectively reduces the van der Waals force between dust and coating. This work provides a novel strategy to prepare self-cleaning and dust removal coatings on PV cover plate.
期刊介绍:
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
