Solar module and manufacturing method therefor

摘要

A solar module is provided which has improved output characteristics. The solar module (1) includes a first protecting member (21), a second protecting member (22), a first solar cell (10a) and a second solar cell (10b), and a first wiring member (11A). The first solar cell (10a) and the second solar cell (10b) are arranged between the first protecting member (21) and the second protecting member (22). The first wiring member (11A) electrically connects the first solar cell (10a) to the second solar cell (10b). A first conductive member (17a) is arranged on the same surface of the first solar cell (10a) as the second protecting member (22). The tip of protrusion portions (11c) formed on the surface of the first wiring member (11A) and the first conductive member (17a) are connected electrically by welding.

主权项

1. A solar module comprising:
a first protecting member, a second protecting member, a first solar cell, and a second solar cell arranged between the first protecting member and the second protecting member, a first conductive member formed on a surface of the first solar cell on the same side as the second protecting member and connected by an adhesive layer, wherein the adhesive layer comprises a resin adhesive, and a first wiring member electrically connecting the first solar cell and the second solar cell, the first wiring member comprising a concave portion and a protruding portion on a surface facing the first protecting member, wherein the protruding portion of the first wiring member is welded to and faces the first conductive member in an overlap section of the first wiring member and the first conductive member, the concave portion of the first wiring member in the overlap section is not welded to and faces the first conductive member, and the first wiring member and the second solar cell are connected by an adhesive layer on the same side as the first protecting member, wherein the adhesive layer comprises a resin adhesive.
