Solar cell panel
A solar cell panel is discussed. The solar cell panel includes a plurality of solar cells each including a substrate and an electrode part positioned on a surface of the substrate, an interconnector for electrically connecting at least one of the plurality of solar cells to another of the plurality of solar cells, and a conductive adhesive film including a resin and a plurality of conductive particles dispersed in the resin. The conductive adhesive film is positioned between the electrode part of the at least one of the plurality of solar cells and the interconnector to electrically connect the electrode part of the at least one of the plurality of solar cells to the interconnector. A width of the interconnector is equal to or greater than a width of the conductive adhesive film.
1. A solar cell panel, comprising:
a plurality of solar cells each including a substrate having a front surface and a back surface opposite the front surface, an electrode part positioned on the front surface of the substrate, and an anti-reflection layer positioned on the front surface of the substrate, the electrode part including a plurality of front electrodes extending in a first direction and at least one front electrode current collector extending in a second direction crossing with the first direction on the front surface of the substrate and having a first width in the first direction;
an interconnector that is positioned in the second direction crossing the plurality of front electrodes and configured to electrically connect adjacent ones of the plurality of solar cells to one another, the interconnector having a second width in the first direction; and
a conductive adhesive film including a resin and a plurality of conductive particles dispersed in the resin, the conductive adhesive film having a third width in the first direction and disposed on a top surface of the at least one front electrode current collector and at least a portion of a side surface of the at least one front electrode current collector,
wherein the second width of the interconnector is greater than the third width of the conductive adhesive film, and the third width of the conductive adhesive film is greater than the first width of the at least one front electrode current collector,
wherein a portion of the conductive adhesive film that is disposed on the at least the portion of the side surface of the at least one front electrode current collector is spaced apart from a front surface of the anti-reflection layer, and
wherein the portion of the conductive adhesive film that is disposed on the at least the portion of the side surface of the at least one front electrode current collector overhangs a portion of the front surface of the anti-reflection layer.
2. The solar cell panel of claim 1 , wherein the first width of the at least one front electrode current collector is equal to or less than about 2 mm.
3. The solar cell panel of claim 1 , wherein the second width of the interconnector and the third width of the conductive adhesive film are less than about 1.5 times the first width of the at least one front electrode current collector.
4. The solar cell panel of claim 1 , wherein the second width of the interconnector is less than about 1.5 times the third width of the conductive adhesive film and the first width of the front electrode current collector.
5. The solar cell panel of claim 1 , wherein the predetermined distance is equal to or greater than about 0.1 times the thickness of the at least one front electrode current collector.
6. The solar cell panel of claim 1 , wherein the conductive adhesive film is only disposed on the at least the portion of the side surface of the at least one front electrode current collector so that another portion of the side surface of the at least one front electrode current collector is exposed.
