Abstract: To provide a cover glass for a solar cell module which can sufficiently maintain the power generation efficiency of a solar cell module, even when a design is imparted to the entire surface of the cover glass so as to make solar cells be invisible from the outside, and a solar cell module.To provide a cover glass 14 to be bonded on light-receiving surfaces 16A and 16B of solar cells 16 via an encapsulant material 18, which has a visible transmittance of from 0% to 60% and an average infrared transmittance of from 20% to 100%, which is a value calculated by simply averaging transmittances at 5 nm intervals in an infrared region at a wavelength of from 780 nm to 1,500 nm.

Abstract: A glass frit includes a glass which contains: Li; at least one selected from the group consisting of B, Si, P, Ge, and Te; O; and at least one selected from the group consisting of F, Cl, Br, and I. The glass is to turn into a crystallized glass including an amorphous phase and a crystalline phase, the crystalline phase precipitated by a heat treatment at a temperature equal to or higher than a glass transition temperature and equal to or lower than a glass crystallization temperature. The crystallized glass shows diffraction peaks at 2θ=22.8±0.5°, 2θ=32.1±0.5° and 2θ=39.6±0.5° in a powder X-ray diffraction pattern using Cu—Kα radiation.
