The coated glass sheet of the present invention includes: a glass sheet; and a coating film provided on at least one principal surface of the glass sheet and having a smooth surface. The coating film includes: isolated closed pores present within the coating film; and a matrix. The coating film is substantially free of open pores open at the surface of the coating film. For the coated glass sheet of the present invention, a transmittance gain is 2.5% or more, the transmittance gain being calculated by subtracting an average transmittance of the glass sheet as determined by applying light having wavelengths of 380 to 1100 nm to the glass sheet in the absence of the coating film on the surface of the glass sheet from an average transmittance of the coated glass sheet as determined by applying light having the wavelengths to the coated glass sheet from a side on which the coating film lies.

The present invention provides a glass article including a photocatalyst filmcontaining silicon oxide particlesand titanium oxide particles, and a glass sheet. Assuming that the photocatalyst filmhas a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheetand a position spaced from the surface by 0.6 T toward a surface of the photocatalyst filmin a thickness direction of the photocatalyst film. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst filmwhile maintaining the film strength and photocatalytic function of the photocatalyst film

In a low reflection coating glass sheet, a low reflection coating is a porous film including solid fine particles containing silicon oxide as a main component and a binder containing silicon oxide. The fine particles are solid particles. At least 70% of the fine particles aggregate to form secondary particles each having an aspect ratio of 1.8 to 5, a minor axis of 20 to 60 nm, and a major axis of 50 to 150 nm, when the aspect ratio is defined as the ratio of the major axis to the minor axis of the secondary particle. The low reflection coating has a thickness of 50 to 250 nm. This low reflection coating has a structure suitable for increasing the transmittance gain.

A cover glass of the present invention for photoelectric conversion devices includes a glass sheet having surface asperities and a reflection-reducing film formed over the surface asperities of the glass sheet. The surface asperities of the glass sheet have an average spacing Sm of 0.3 mm or more and 2.5 mm or less and an arithmetic average roughness Ra of 0.3 &#x3bc;m to 5 &#x3bc;m. The reflection-reducing film includes fine silica particles having an average particle diameter of 50 to 200 nm and a binder for the fine silica particles, and the fine silica particles are uniformly arranged in a single layer on peak portions of the surface asperities in such a manner that a filling fraction F is 35 to 65%. A transmittance gain is 2.37% or more, the transmittance gain being obtained by subtracting an average transmittance of the glass sheet as measured when light having wavelengths ranging from 380 to 1100 nm are incident on a face of the glass sheet that has the surface asperities, from an average transmittance of the cover glass as measured when light having the wavelengths are incident on a reflection-reducing film side of the cover glass. Thus, a cover glass for photoelectric conversion devices that exhibits a high transmittance gain is provided.

Glass article provided with photocatalyst film

Provided is a glass article that improves the film strength of a photocatalyst film while maintaining the photocatalytic function and the reflection suppressing function of the photocatalyst film. The photocatalyst film on the glass sheet is formed to contain, in mass %, 50 to 82% of silicon oxide particles, 8 to 40% of titanium oxide particles, and 7 to 20% of a binder component composed of silicon oxide. The average particle diameter of the silicon oxide particles is set to at least 5 times the average particle diameter of the titanium oxide particles. The photocatalyst film is formed to have a structure such that some of the silicon oxide particles in the film serve as protruding silicon oxide particles that are not in contact with the glass sheet and that have their top portions protruding from the surrounding titanium oxide particles and being exposed on the surface of the film, while some of the titanium oxide particles are interposed between the glass sheet and the protruding silicon oxide particles.
