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.

Solar cell module and method for manufacturing solar cell module

In the solar cell module including a plurality of solar cells interconnected with wiring members, each of the solar cells includes a plurality of front-side finger electrodes that are disposed on a light-receiving surface of the solar cell and connected with tabs and a plurality of rear-side finger electrodes that are disposed on a rear surface of the solar cell and connected with tabs. Rear-side auxiliary electrode sections are arranged in regions, which is wider than the front-side finger electrodes, on the rear surface opposite to regions where the front-side finger electrodes are present.

Solar cell module

A plurality of solar cells are sealed by an encapsulant between a first protective member and a second protective member. A fixing member fixes, among the plurality of solar cells, a first solar cell and a second solar cell that are adjacent to each other. The fixing member includes a release surface and a non-release surface that are oriented in opposite directions. The non-release surface has disposed thereon a first bonding region and a second bonding region that have adhesive strength, and a non-bonding region different from the first bonding region and the second bonding region.

Solar cell module including plurality of solar cells

The solar cell () of the present invention comprises: a first electrode () including a plurality of finger portions (), and a busbar portion () connected electrically to the plurality of finger portions (), each of the plurality of finger portions () extending along a first direction (y), and the plurality of finger portions () being arrayed along a second direction (x) perpendicular to the first direction (y) leaving gaps therebetween; and a plurality of protruding portions () provided on at least one side of a first main surface (A) in the first direction (y) of the busbar portion (). The plurality of protruding portions () are provided so that the total perimeter of the protruding portions () per unit area at the ends of the first main surface (A) in the second direction (x) is longer than the total perimeter of the protruding portions () per unit area in the central portion. By means of these characteristics, the solar cell of the present invention is able to effectively suppress delamination of wiring material () by suppressing delamination of the ends, which is where delamination of the wiring material begins when the wiring material () is connected to the busbar.

Solar battery module

In accordance with the present invention, the dividing groovesare formed so as not to be parallel to cleavage planes of the semiconductor substrate, and the semiconductor substrateis bent along the dividing grooves, whereby the semiconductor substrateis fractured along the dividing grooves

Method for fracturing semiconductor substrate, method for fracturing solar cell, and the solar cell

Solar battery

A method and apparatus for breaking a semiconductor substrate along a predetermined area over which a split groove is formed. The breaking apparatus includes a table for placing a portion of the semiconductor substrate inside the predetermined area and a breaking blade being operable to move downward from a position above the semiconductor substrate placed on the table to thereby compress a portion of the semiconductor substrate outside the predetermined area so that the semiconductor substrate is broken along the split groove. The predetermined area of the semiconductor substrate has at least a neighboring pair of sides intersecting at an angle of less than 180 degrees, and the breaking blade has a projection which, when the semiconductor substrate is broken, compresses a portion of the semiconductor substrate outside the one side so that the one side is compressed ahead of the other side.
