Abstract: A solar cell module includes: a solar cell having a front surface and a back surface; a front surface side encapsulant disposed on a front surface side of the solar cell, the front surface side encapsulant including a transparent resin sheet; a light reflector protruding from an end portion of the solar cell, the light reflector including a light reflection layer that reflects incident light, and a substrate layer that is disposed on the light reflection layer on a light incident side; and an ultraviolet absorber disposed closer to the light incident side than the light reflection layer, the light incident side being a back surface side of the front surface side encapsulant.

Abstract: A solar cell module includes solar cells. encapsulants are layered on surfaces of the solar cells. A glass substrate is layered on the encapsulants. The solar cell module further includes an epoxy resin-containing member. Each encapsulant includes the ultraviolet ray-absorbing member. The ultraviolet ray-absorbing member sets the transmittance to 1% or less at the wavelengths ranging from 300 to 360 nm.

Abstract: A solar cell module includes: two solar cells adjacent one another across a space; an elongated light reflector extending over the two solar cells; and a front protector covering front surfaces of the two solar cells and the light reflector. In a plan view of the two solar cells, each of the two solar cells has chamfered corners and a substantially octagonal shape with linear long sides and linear or non-linear short sides, connected alternately. The light reflector, in the plan view, protrudes in the longitudinal direction from an intersection between a first long side facing another long side across the space, among the long sides, and a first short side one end of which is connected to the first long side, among the short sides, to cause light reflected by the uneven structure of the light-reflective film to reach at least one of the two solar cells.

Abstract: A solar cell module includes a first solar cell, a second solar cell disposed with a gap from the first solar cell, and a light reflection sheet bridging between the first solar cell and the second solar cell across the gap. The light reflection sheet is at least partially bent between the first and second solar cells.

Abstract: A solar cell module includes: a light-diffusing member adjacent to a solar cell; a tab line disposed on front surfaces of solar cells and having a light-diffusing shape on a light-entering side; and a protective member having first and second principal surfaces. When an average distance between a front surface of the solar cell and the second principal surface is expressed as D, a refractive index of the protective member is expressed as n, and a critical angle for total reflection satisfying sin R=1/n is expressed as R, the tab line is disposed in a zone other than a zone between a position at a distance of 3.46×D from, among ends of the light-diffusing member, an end closest to the solar cell and a position at a distance of 2×D×tan R from, among the ends, an end farthest from the solar cell.
