Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a solar energy shingle assembly according to an embodiment of the present invention.
Referring to fig. 1, a solar shingle assembly 1 according to an embodiment of the present invention includes a first cell unit 10 and a second cell unit 20. Fig. 1 shows that the solar energy shingle assembly 1 comprises a cell string formed by overlapping and serially connecting 15 cell units, however, it should be noted that the solar energy shingle assembly provided by the embodiment of the utility model can also be an assembly formed by connecting a plurality of cell strings in parallel. It should be noted that the number of the battery units included in the solar shingle assembly 1 provided by the embodiment of the present invention is not particularly limited, and the solar shingle assembly 1 provided by the embodiment of the present invention may include more or less than 15 battery units. In addition, the structure of each battery cell and the manner of overlapping connection with each other are the same as each other. Therefore, in the present embodiment, the structure of the battery cells and the manner of overlapping connection with each other are described in detail by taking the first battery cell 10 and the second battery cell 20 as an example, so as to describe in detail the structure of the solar shingle assembly 1 provided by the embodiment of the present invention.
In addition, as shown in fig. 1, the solar shingle assembly provided by the present embodiment further includes a third battery cell 30 at the end, the third battery cell 30 needs to be connected to a solder strip 40, and the solder strip 40 is used for connecting a bypass diode. In the present embodiment, as shown in fig. 6, the third battery cell 30 forms a blank region P (without providing conductive grid lines) at a portion connected to the solder ribbon 40, then forms a conductive paste in a paste-like state in the blank region by a dispenser, and then is connected to the solder ribbon 40 by the conductive paste. By replacing the conventional silver paste with the conductive adhesive, the use of the silver paste can be saved, and the cost is reduced.
Fig. 2 is a schematic diagram of an overlapping connection of a first battery cell and a second battery cell according to an embodiment of the present invention.
Referring to fig. 2, a first edge 100 of a first battery cell 10 and a second edge 200 of a second battery cell 20 are electrically connected by a plurality of spaced apart conductive adhesive segments 300 to form a battery string, the first and second edges 100 and 200 being parallel to each other and to a first direction. A first edge gate line segment 410 connected to the conductive adhesive segment 300 is disposed between two adjacent conductive adhesive segments 300 of the first edge 100, and a second edge gate line segment 420 connected to the conductive adhesive segment 300 is disposed between two adjacent conductive adhesive segments 300 of the second edge 200. Since the first edge gate line segment 410 and the second edge gate line segment 420 correspond to each other one by one, and the first edge gate line segment 410 overlaps the second edge gate line segment 420, the first edge gate line segment 410 (shown by a dotted line) overlaps the second edge gate line segment 420 (not shown in the figure) in fig. 2.
After the first and second battery cells 10 and 20 are overlap-connected to each other, the conductive adhesive segment 300 connects the first and second edges 100 and 200 together while the first and second edge grid line segments 410 and 420 correspond to each other, and the height of the conductive adhesive segment 300 is generally set to be higher than or equal to the sum of the heights of the first and second edge grid line segments 410 and 420, so that the first and second edge grid line segments 410 and 420 do not affect the connection of the conductive adhesive segment 300 to the first and second edges 100 and 200 after the first and second battery cells 10 and 20 are overlap-connected.
Specifically, a right edge (with respect to the orientation in fig. 2) of the first battery cell 10 is a first edge 100, a left edge (with respect to the orientation in fig. 2) of the second battery cell 20 is a second edge 200, the first edge 100 of the first battery cell 10 is overlapped with the second edge 200 of the second battery cell 20, and the first edge 100 is located at an upper side of the second edge 200. The first edge 100 and the second edge 200 are connected together by a plurality of spaced apart conductive adhesive segments 300.
The first edge gate line segment 410 and the second edge gate line segment 420 have a height of 10 to 30 μm and a width of 40 to 500 μm. The first edge gate line segment 410 and the second edge gate line segment 420 may be prepared from silver paste or aluminum paste. When the first edge gate segment 410 or the second edge gate segment 420 is made of silver paste, the height of the first edge gate segment 410 or the second edge gate segment 420 may be 10 to 15 μm, and the width thereof may be 40 to 100 μm, and when the first edge gate segment 410 or the second edge gate segment 420 is made of aluminum paste, the height of the first edge gate segment 410 or the second edge gate segment 420 may be 10 to 30 μm, and the width thereof may be 100 to 500 μm. For example, the first edge grid line segment 410 is disposed on the back surface of the first battery unit 10, and may be made of aluminum paste, and has a height of 10-15 μm and a width of 40-100 μm; the second edge grid line segment 420 is disposed on the front surface of the second battery unit 20, and may be made of silver paste, and has a height of 10-30 μm and a width of 100-500 μm.
The conductive adhesive section 300 has a height of 30 to 50 μm and a width of 0.1 to 1 mm.
In the embodiment, the conductive adhesive between the first edge 100 and the second edge 200 is provided as a segment, that is, a plurality of spaced conductive adhesive segments, so that the amount of the conductive adhesive can be saved, and the cost can be reduced. In order to solve the problem that the current conduction is interrupted due to the fact that no conductive adhesive segment is arranged between the conductive adhesive segments, in the embodiment, a first edge grid line segment 410 connected with the conductive adhesive segment 300 is arranged at a blank position between the conductive adhesive segments 300 of the first edge 100, so that the current on the first battery unit 10 between the conductive adhesive segments 300 can also be conducted to the conductive adhesive segments 300 through the first edge grid line segment 410; a second edge grid line segment 420 connected to the conductive adhesive segment 300 is disposed at a blank position between the conductive adhesive segments of the second edge 200, so that a current between the conductive adhesive segments on the second battery cell 20 can be conducted to the conductive adhesive segment 300 through the second edge grid line segment 420, and then the first battery cell 10 and the second battery cell 20 are electrically connected through the conductive adhesive segment 300. Therefore, the using amount of the conductive adhesive can be saved, the using amount of the metal grid line slurry can be reduced, and the cost is reduced.
The following describes in detail specific structures of the first battery cell 10 and the second battery cell 20 provided in an embodiment of the present invention with reference to fig. 3 and 4, taking the first battery cell 10 located on the upper side of the second battery cell 20 as an example. Fig. 3 is a schematic diagram of a back structure of a first battery unit according to an embodiment of the present invention. Fig. 4 is a schematic diagram of a front structure of a second battery cell according to an embodiment of the present invention.
Referring to fig. 3, the back surface of the first battery cell 10 is further provided with a plurality of first conductive grid lines 510 extending perpendicular to the first edge 100 and parallel to each other, and the plurality of first conductive grid lines 510 extend from the other edge opposite to the first edge 100 in parallel to the first edge 100 up to the first edge 100. One part of the plurality of first conductive gate lines 510 extends to the first edge 100 and is connected to the conductive adhesive segment 300, and the other part extends to the first edge 100 and is connected to the first edge gate line segment 410. Thus, when the first battery cell 10 and the second battery cell 20 are overlapped and connected, a portion of the first conductive grid line 510 of the first battery cell 10 directly connected to the conductive adhesive segment 300 directly conducts current to the conductive adhesive segment 300, but not directly connected to the conductive adhesive segment 300, and another portion of the first conductive grid line 510 directly connected to the first edge grid line segment 410 conducts current to the first edge grid line segment 410, and then to the conductive adhesive segment 300 through the first edge grid line segment 410.
Specifically, the height of the first conductive gate line 510 is 10 to 30 μm, and the width is 25 to 200 μm. The first conductive gate line 510 may be made of silver paste or aluminum paste. When the first conductive gate line 510 is made of silver paste, the height of the first conductive gate line 510 is 10 to 15 μm, and the width thereof is 25 to 50 μm, and when the first conductive gate line 510 is made of aluminum paste, the height of the first conductive gate line 510 is 10 to 30 μm, and the width thereof is 80 to 200 μm. In the present embodiment, the first conductive grid line 510 is disposed on the back surface of the first battery cell 10, and is made of aluminum paste, and has a height of 10 to 30 μm and a width of 80 to 200 μm. In addition, for example, a 158-sized battery piece is taken as an example, 100 to 200 first conductive grid lines 510 are arranged on the first battery unit 10, and the interval between two adjacent first conductive grid lines 510 is 0.8 to 1.5 mm.
Referring to fig. 4, the rear surface of the second battery cell 20 is further provided with a plurality of second conductive grid lines 520 extending in parallel with each other perpendicularly to the second edge 200, the plurality of second conductive grid lines 520 extending from the other edge parallel to and opposite to the second edge 200 up to the second edge 200. One part of the plurality of second conductive gate lines 520 extends to the second edge 200 and is connected to the conductive adhesive segment 300, and the other part extends to the second edge 200 and is connected to the second edge gate line segment 420. Thus, when the second battery cell 20 is overlapped with the first battery cell 10, a portion of the second conductive grid line 520 of the second battery cell 20 directly connected to the conductive adhesive segment 300 directly conducts current to the conductive adhesive segment 300, but not directly connected to the conductive adhesive segment 300, and another portion of the second conductive grid line 520 directly connected to the second edge grid line segment 420 conducts current to the second edge grid line segment 420, and then to the conductive adhesive segment 300 through the second edge grid line segment 420.
Specifically, the height of the second conductive gate line 520 is 10 to 30 μm, and the width is 25 to 200 μm. The second conductive gate line 520 may be made of silver paste or aluminum paste. When the second conductive gate line 520 is made of silver paste, the height of the second conductive gate line 520 is 10 to 15 μm and the width is 25 to 50 μm, and when the second conductive gate line 520 is made of aluminum paste, the height of the second conductive gate line 520 is 10 to 30 μm and the width is 80 to 200 μm. In the embodiment, the second conductive grid lines 520 are disposed on the front surface of the second battery unit 20, and are made of silver paste, and have a height of 10-15 μm and a width of 25-50 μm. In addition, for example, a 158-sized battery piece is taken as an example, 100 to 200 second conductive grid lines 520 are disposed on the second battery unit 10, and the interval between two adjacent second conductive grid lines 520 is 0.8 to 1.5 mm.
The first and second edge gate lines 410 and 420 have a height equivalent to the first and second conductive gate lines 510 and 520, but a width greater than the first and second conductive gate lines 510 and 520 because the first and second edge gate lines 410 and 420 require a current to converge the plurality of first and second conductive gate lines 510 and 520.
The first battery cell 10 and the second battery cell 20 may be formed by cutting an entire battery sheet in a direction perpendicular to the first conductive grid line 510 or perpendicular to the second conductive grid line 520. For convenience of the manufacturing process, it is preferable that the first battery cell 10 and the second battery cell 20 are designed to have the same structure as each other so as to be overlapped and connected with other more battery cells to form a longer battery string. That is, the front surface of the first battery cell 10 may have the same structure as the front surface of the second battery cell 20, and the rear surface of the second battery cell 20 may have the same structure as the rear surface of the first battery cell 10. It should be noted, however, that the present invention is not so limited.
For example, a 158-sized whole battery piece is cut into 5 battery cells in a direction perpendicular to the first conductive grid lines 510 or perpendicular to the second conductive grid lines 520, the front side of each battery cell has the same front side structure as the second battery cell 20, and the back side of each battery cell has the same back side structure as the first battery cell 10. Wherein the length of each conductive adhesive section 300 is 15-16 mm, and the number of the conductive adhesive sections is 6; the first edge grid line 410 and the second edge grid line 420 correspond to each other, the lengths of the first edge grid line and the second edge grid line are 15-16 mm, and the number of the first edge grid line and the second edge grid line is 5.
Fig. 5 is a cross-sectional view taken along a-a in fig. 2.
Referring to fig. 5, the first battery unit 10 and the second battery unit 20 are connected only by the conductive adhesive segment 300, and the height difference between the first battery unit 10 and the second battery unit 20 is only the height of the conductive adhesive segment, so that the height difference between the first battery unit 10 and the second battery unit 20 is reduced, and not only can the subfissure or crack of the subsequent assembly lamination process be reduced, but also the material for filling the space by using auxiliary materials such as EVA and the like can be reduced, and the cost is reduced.
