Abstract:
1. A solar cell panel comprising: a plurality of solar cells, each solar cell including a substrate, an emitter layer that is positioned at a light receiving surface of the substrate and forms a p-n junction along with the substrate, a plurality of front electrodes electrically connected to the emitter layer and extending parallel to one another in a first direction, a plurality of front electrode current collectors electrically connected to the emitter layer in a second direction crossing the first direction, wherein each front electrode current collector intersects at least two of the plurality of front electrodes, and an alignment mark positioned on the emitter layer aligned with and spaced apart from the front electrode current collector and being electrically connected to the emitter layer; an interconnector electrically connecting adjacent ones of the plurality of solar cells to each other, the interconnector being positioned in a second direction crossing the plurality of front electrodes; and a conductive adhesive film including a resin and a plurality of conductive particles dispersed in the resin, the conductive adhesive film being positioned between the plurality of front electrodes and the interconnector in the second direction, wherein the alignment mark is formed of the same material as the plurality of front electrodes, wherein a length of a front electrode current collector of the plurality of front electrode current collectors in the second direction is smaller than a distance between a first front electrode positioned at a first row of the plurality of front electrodes and a last front electrode positioned at a last row of the plurality of front electrodes, wherein the conductive adhesive film directly contacts the plurality of front electrodes, the alignment mark and at least one front electrode current collector of the plurality of front electrode current collectors along the second direction, and wherein the alignment mark is positioned between adjacent front electrode current collectors along the second direction.
