| 摘要 |
The present invention provides a solar cell (400, 700) including a substrate (410, 710, 810, 910), a first front bus (420, 420A, 420B, 720), and a first rear bus (430, 430A, 430B). The substrate (410, 710, 810, 910) has a front surface (412, 712) and a rear surface (414, 714). The first front bus (420, 420A, 420B, 720) is located on the front surface (412, 712) of the substrate (410, 710, 810, 910) along a first direction for collecting current generated by the substrate (410, 710, 810, 910), and for providing a first front contact electrode (422, 822, 922). The first rear bus (430, 430A, 430B) is located on the rear surface (414, 714) of the substrate (410, 710, 810, 910) along a second direction for collecting current generated by the substrate (410, 710, 810, 910), and for providing a first rear contact electrode (432, 832, 932). |
