As shown in fig. 2, in the tile-stacking manner, one cell 20 of two adjacent cells 10, 20 will block the other cell 10 (one end of the cell 20 is stacked on the cell 10), which results in a waste of the area of the cell 10.
The embodiment of the utility model is as follows:
example 1
As shown in fig. 3, a series structure of solar cells comprises two cells 10, 20 laid adjacently, wherein the two cells 10, 20 are connected in series through a conductive connecting member 30; the conductive connecting piece 30 extends from the front surface of one cell piece 10 to the back surface of the other cell piece 20; the borderlines 21 and 11 of the opposite ends of the two battery pieces 20 and 10 are arranged up and down, and the borderlines 21 and 11 of the opposite ends of the two battery pieces 20 and 10 are aligned up and down;
the battery piece 10 with the opposite end edge line 11 positioned below is connected with the conductive connecting piece 30 on the front surface;
the battery piece 20 with the opposite end edge line 21 positioned above is connected with the conductive connecting piece 30 at the back;
the cell sheet 20 with the opposite end edge line 21 at the top is supported by the conductive connecting member 30 and/or a support structure (not shown) provided in the solar cell module.
In the embodiment 1, the borderlines 21, 11 of the opposite ends of the two adjacent battery pieces 20, 10 are aligned up and down, so that the laying density of the battery pieces can be maximized in the horizontal direction;
and the sidelines 21 and 11 of the opposite ends of the two adjacent battery pieces 20 and 10 are aligned up and down, that is, the two adjacent battery pieces 10 and 20 are not shielded, so that the problem that one battery piece shields the other battery piece in the two adjacent battery pieces due to the tile-stacking technology can be avoided, and the waste of the area of the battery piece 10 is avoided.
Example 2
As shown in fig. 4, the difference is that, based on embodiment 1:
the borderlines 11 and 21 of the opposite ends of the two battery pieces 10 and 20 are straight lines;
the number of the conductive connecting pieces 30 is multiple, and the conductive connecting pieces 30 are sequentially arranged at intervals along the extending direction of the opposite end edge lines 11 and 21 of the two battery pieces 10 and 20; and the conductive connecting members 30 are perpendicular to the side lines 11, 21 of the opposite ends of the two battery pieces 10, 20.
Example 3

the extending portions 32 are perpendicular to the side lines 11 and 21 of the opposite ends of the two battery cells 10 and 20.
Example 5
As shown in fig. 7, the difference is that in example 3:
the extending portions 32 are parallel to the side lines 11, 21 of the opposite ends of the two battery pieces 10, 20.
Example 6
On the basis of example 1, the difference lies in:
the conductive connecting piece is strip-shaped and is parallel to side lines of opposite ends of the two battery pieces.
It should be noted that, although the edge lines of the opposite ends of two adjacent battery plates are aligned up and down in each embodiment, if a slight deviation occurs in the up-down alignment of the edge lines in actual production/actual products, the slight deviation is also within the protection scope of the present invention.
In addition, the above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
