An industrial sol-gel method to prepare silica film with TEOS as precursor and ammonia,HCl as catalyst has been developed.In this paper,SiO2 antireflective(AR)coatings were dip-coated on low-iron glasses which encapsulate the crystalline silica solar cells.After surface modification on the film,the hydrophobicity of the film is improved and the contact angle is changed from 40°to 110°.Large area of AR coatings were designed and prepared,the average transmittance between 400 nm and 800 nm is increased by more than 5%.The hydrophobicity and the scratch-resistant property of the film can meet the demands of industrial manufacture.
