Abstract: A first insulating layer is layered on first surfaces of solar cells. Herein, the first insulating layer is formed of polyolefin or ethylene-vinyl acetate copolymer (EVA). A second insulating layer is layered on the first insulating layer. Herein, the second insulating layer is formed of polyester resin. A first inter-cell wire rod and second inter-cell wire rod provided to the first surfaces of the solar cells are partially brought into contact with the second insulating layer.

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.

Abstract: A solar cell module includes a first solar cell; and a light reflection member at least partially positioned on a side of the first solar cell in a first direction orthogonal to a thickness direction of the first solar cell. The light reflection member includes an insulating member and a conductive light reflection film on the insulating member in the thickness direction. A thickness of the light reflection member is larger than a thickness of the first solar cell, in the thickness direction.

Abstract: A solar cell module includes solar cells having main surfaces to which inter-cell wiring members are connected, and an insulating member disposed on the main surfaces and the wiring members, and a first lead-out wire provided to the insulating member. The insulating member includes a first insulating layer formed of polyester resin, a second insulating layer formed of polyolefin or EVA and provided between the first insulating layer and the lead-out wires, and a third insulating layer formed of polyolefin or EVA and provided between the first insulating layer and the main surfaces. The third insulating layer has a thickness in a direction perpendicular to the main surfaces larger than a thickness of the second insulating layer.
