Abstract
A solar cell panel includes a plurality of solar cells including first and second solar cells, and a plurality of wiring members electrically connecting the first and second solar cells. A first electrode of each of the first and second solar cells includes a first bus bar including a plurality of first pad portions. The plurality of first pad portions include a first end pad positioned on one end side of the first bus bar and on which an end of the wiring member is positioned, and a first extension pad positioned on the other end side of the first bus bar and on an extension of the wiring member. An area of the first end pad is different from an area of the first extension pad.
Claims20
A solar cell panel comprising:
- a plurality of solar cells including first and second solar cells;
- and
- a plurality of wiring members electrically connecting the first and second solar cells,
- wherein each of the first and second solar cells includes:
- a semiconductor substrate;
- a first conductive region positioned at one surface of the semiconductor substrate or on the one surface of the semiconductor substrate;
- and
- a first electrode electrically connected to the first conductive region,
- wherein the first electrode includes a plurality of first finger lines that are formed in a first direction and are parallel to each other, and a first bus bar including a plurality of first pad portions, is electrically connected to the first finger lines, and is positioned in a second direction intersecting the first direction,
- wherein the plurality of first pad portions include a first end pad positioned on one end side of the first bus bar and on which an end of the wiring member is positioned, and a first extension pad positioned on other end side of the first bus bar and on an extension of the wiring member, and
- wherein an area of the first end pad is different from an area of the first extension pad.
A solar cell comprising:
- a semiconductor substrate;
- a first conductive region positioned at one surface of the semiconductor substrate or on the one surface of the semiconductor substrate;
- and
- a first electrode electrically connected to the first conductive region,
- wherein the first electrode includes a plurality of first finger lines that are formed in a first direction and are parallel to each other, and a first bus bar including a plurality of first pad portions, is electrically connected to the first finger lines, and is positioned in a second direction intersecting the first direction,
- wherein the plurality of first pad portions include a first one end pad positioned on one end side of the first bus bar, and a first other end pad positioned on other end side of the first bus bar, and
- wherein an area of the first one end pad is different from an area of the first other end pad.
