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: a solar cell; a light reflector above a surface of the solar cell or around the solar cell, the light reflector being elongated and including a light reflective film and an insulating component; a protective component that covers the surface of the solar cell; and an encapsulant between (i) the solar cell and the light reflector and (ii) the protective component. The light reflective film has an uneven structure in which a recessed portion and a protruding portion are repeated in a direction crossing a longitudinal direction of the light reflector, and a tangential direction of at least part of a ridge line of the protruding portion and the longitudinal direction intersect when the solar cell is seen in a plan view.

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.
