SOLAR CELL MODULE AND MANUFACTURING METHOD THEREOF

摘要

A solar cell module in the present invention includes: a wiring member electrically connecting solar cell elements to each other; and a structure in which a solder bonding portion is formed by bonding a collecting electrode, which is provided on a light receiving surface of the solar cell element, extends in a first direction parallel to the wiring member, and has a width smaller than that of the wiring member in a cross section vertical to the first direction, and the wiring member together by melting solder, a cross-sectional shape of the solder bonding portion vertical to the first direction has a shape that gradually narrows toward the collecting electrode from a lower surface of the wiring member, and a side surface of the solder bonding portion and a side surface of the wiring member are covered with a thermosetting resin.

主权项

1. A solar cell module comprising:
a wiring member that electrically connects a plurality of solar cell elements to each other; a solder bonding portion that is formed by bonding a collecting electrode, which is provided on a light receiving surface of the solar cell element, extends in a first direction parallel to the wiring member, and has a width smaller than that of the wiring member in a cross section vertical to the first direction, and the wiring member together by melting solder; and a thermosetting resin that covers a side surface of the solder bonding portion, wherein a cross-sectional shape of the solder bonding portion vertical to the first direction has a shape that gradually narrows toward the collecting electrode from a lower surface of the wiring member, and the solder spreads to a side surface of the collecting electrode, and 1a side surface of the wiring member is covered with the thermosetting resin.
