The reduced pressure double glazed glass panel of the present invention includes an outside glass sheet, an inside glass sheet, and a gap portion that are joined together, with the gap portion being formed between the glass sheets and sealed under reduced pressure. Here, the outside glass sheet has a first glass surface disposed to face the outdoor space and a second glass surface disposed to face the gap portion. A Low-E film is formed on the second glass surface. The following relations hold: (Emissivity of Low-E film ∈)≦0.067; 31%≦(Solar reflectance on First glass surface RG(solar))≦40%; (48−RG(solar))%≦(Solar absorptance on First glass surface AG(solar))≦17%; (AG(solar))≦{18.3−(0.07×RG(solar))+(20×∈)}%; (Solar heat gain coefficient SHGC)≦0.50; and (Thermal transmittance U value)≦1.2 W/m2·K or less. According to the present invention, it is possible to provide a reduced pressure double glazed glass panel having sufficient heat insulating and heat shielding properties and being less susceptible to bending when exposed to solar radiation.

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 μm to 5 μm. 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.
