Solar cell module having interconnector and method of fabricating the same

摘要

A solar cell module having an interconnector and a method of fabricating the same are disclosed. The solar cell module includes a plurality of solar cells and an interconnector including a first area electrically connected to one of two adjacent solar cells of the plurality of solar cells, a second area electrically connected to the other of the two adjacent solar cells, and a third area connecting the first area to the second area. At least one of the first area and the second area of the interconnector has at least one uneven surface, and the third area of the interconnector has a substantially planarized surface.

1. A solar cell module, comprising:
a plurality of solar cells which has a front surface facing a light incident direction and a back surface facing opposite to the light incident direction; and an interconnector including a first area electrically connected to one of two adjacent solar cells of the plurality of solar cells, a second area electrically connected to the other of the two adjacent solar cells, and a third area connecting the first area to the second area, wherein each of the first, second, and third areas of the interconnector has a first surface and a second surface opposite the first surface respectively, wherein the first surface of the first area has a first uneven surface, the second surface of the first area is an entirely flat surface, and the entirely flat second surface of the first area entirely electrically contacts the one of the two adjacent solar cells of the plurality of solar cells, the first uneven surface of the first area facing the light incident direction, and the entirely flat second surface of the first area facing the front surface of the one of the two adjacent solar cells, wherein the second surface of the second area has a second uneven surface, the first surface of the second area is an entirely flat surface, the entirely flat first surface of the second area entirely electrically contacts the other of the two adjacent solar cells of the plurality of solar cells, and the second area is positioned on lower parts of the other of the two adjacent solar cells of the plurality of solar cells, the second uneven surface of the second area facing opposite to the light incident direction, and the entirely flat first surface of the second area facing the back surface of the other of the two adjacent solar cells, wherein each of the entire first surface and the entire second surface of the third area of the interconnector are entirely flat, wherein a width of the second area of the interconnector is greater than a width of the first area of the interconnector, and wherein the third area of the interconnector has a gradually increasing width as is goes from an end in contact with of the first area of the interconnector to an end in contact with the second area of the interconnector, and the gradually increasing width is symmetric about a centerline of the interconnector.
