Embodiment Construction

[0020] Embodiment, referring to shown in Fig. 1, a kind of novel anti-reflection film solar cover glass of the present invention comprises a glass base layer 1, a first porous SiO 2 coating layer 2 and a second porous SiO 2 Coating layer 3; the first porous SiO 2 The coating layer 2 is formed by sol-gel method and spraying process to coat the first sol on the surface of the front surface of the glass substrate 1 after drying. The second porous SiO 2 The coating layer 3 is coated with the second sol on the first porous SiO by a sol-gel method and a spraying process. 2 The surface of the coating layer 2 is formed after drying.

[0021] in,

[0022] The first sol is based on tetraethyl orthosilicate (TEOS) and dimethyldiethoxysilane (DDS) as raw materials, ethanol as solvent, ammonia as catalyst, polyethylene glycol (PEG) as plasticizer, through co- Dissolving, aging, and co-hydrolysis-polycondensation reaction; the second sol solution is made of orthoethyl silicate (TEOS) an...

Abstract

The invention discloses novel solar covering glass with an anti-reflective film and a manufacturing method thereof. The glass comprises a glass base layer, a first porous SiO2 film coating layer and a second porous SiO2 film coating layer. The manufacturing method comprises the steps of preparing first sol and second sol; respectively spraying the first sol and the second sol on the surface of the front side of the glass base layer by adopting spray technology to plate the first porous SiO2 film coating layer and the second porous SiO2 film coating layer in turn; and performing drying and toughening treatment on the glass base layer to prepare the covering glass finished product plated with two layers of the anti-reflective films. Tests prove that the transmissivity of the covering glass finished product exceeds 95 percent in a wavelength range of between 400 and 800nm. The glass has the characteristics of simple structure, simple technical process, easy implementation and the like.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic glass, in particular to a novel anti-reflection film solar cover glass and a manufacturing method. Background technique [0002] As low-carbon energy is paid more and more attention, how to improve the conversion efficiency of solar cells has become particularly urgent. The cover glass is an important part of the solar cell, it can protect the cell and let the light pass through. For the substrate glass of the cover glass, various manufacturers at home and abroad have reduced the iron content and adjusted the glass formula, so that the light transmittance of the cover glass has reached more than 91%, while the remaining 8-9% of the solar energy has been lost. The cover glass is reflected. Since the light absorbed by the cover glass itself is very small, if we simply start from the material of the cover glass, there is little room for improving the light transmittance of the cover glas...
