Description

Technical Field

[0001] This application relates to the field of photovoltaic cell manufacturing technology, and in particular to a segmented cell and a photovoltaic module. Background Technology

[0002] Photovoltaic power generation technology, as a mainstream technology for utilizing solar energy resources, is an important area of ​​green energy development and has already moved towards marketization and commercialization. With continuous technological advancements, half-cell and tandem photovoltaic modules have developed rapidly in recent years. Both half-cell and tandem photovoltaic modules require the cutting of solar cells during manufacturing. Specifically, the process involves cutting complete rectangular solar cells (with large / small chamfers) into smaller pieces.

[0003] Currently, solar cells are typically cut using a uniform cutting method, which involves cutting a complete rectangular solar cell into smaller pieces of the same size. However, the application of these smaller pieces is limited, and multiple cutting operations can exacerbate the power loss of the solar cell. Utility Model Content

[0004] Therefore, it is necessary to provide a slab-type cell and photovoltaic module to address the problems of limited application patterns and severe power loss of existing small-sized solar cell fragments.

[0005] A segmented battery, the segmented battery comprising a first segmented battery forming a first pattern assembly and a second segmented battery forming a second pattern assembly;

[0006] Both the first and second segmented batteries are cut from a whole battery, and the first and second segmented batteries have different sizes.

[0007] In one embodiment, the length of the first segmented battery is L1, and the length of the second segmented battery is L2, with L1 > L2, in a direction parallel to the light-receiving surface of the segmented battery and perpendicular to the cutting direction of the whole battery.

[0008] In one embodiment, 1.1L2≤L1≤2.6L2.

[0009] In one embodiment, 49.5mm≤L1≤149.5mm, 45mm≤L2≤57.5mm.

[0010] In one embodiment, in the whole battery cell, the first segmented battery cell is located near the middle of the whole battery cell, and the second segmented battery cell is located near the edge of the whole battery cell.

[0011] In one embodiment, both the first segmented battery and the second segmented battery have a cut edge and a cut angle formed by the cut edge;

[0012] The cutting angle can be any one of a right angle, a rounded corner, or a chamfered corner.

[0013] In one embodiment, when the cutting angle is a rounded corner, the radius of the cutting angle is R, where 0.1mm ≤ R ≤ 0.5mm;

[0014] When the cutting angle is a chamfer, the angle of the cutting angle is α, where 0 < α ≤ 30°.

[0015] In one embodiment, a plurality of the first segmented batteries in the first pattern component are arranged side by side or in a matrix, and the plurality of the first segmented batteries are connected in parallel or in series.

[0016] In the second type component, multiple second segmented batteries are arranged side by side or in a matrix, and the multiple second segmented batteries are connected in parallel or in series.

[0017] In one embodiment, the whole battery can be cut into at least one first segmented battery and at least one second segmented battery.

[0018] A photovoltaic module, the photovoltaic module comprising:

[0019] At least one segmented battery as described in any of the above technical solutions.

[0020] The aforementioned slab-type solar cells and photovoltaic modules include first slab-type solar cells and second slab-type solar cells. Since the first slab-type solar cells and second slab-type solar cells have different sizes, they are cut from a whole solar cell to form first slab-type solar cells and second slab-type solar cells with different preset sizes. The first slab-type solar cells can form first-type modules, and the second slab-type solar cells can form second-type modules. That is, the first slab-type solar cells and second slab-type solar cells can form modules of different specifications, expanding the types of modules that can be manufactured using slab-type solar cells. Moreover, the first slab-type solar cells and second slab-type solar cells of different sizes are cut from the same whole solar cell. Different sizes of first slab-type solar cells and second slab-type solar cells can be cut from the same whole solar cell as needed, reducing the number of times the whole solar cell is cut and reducing the cutting power loss of the first-type modules and second-type modules after molding.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0038] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0040] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0042] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0043] See Figures 1-3 As shown, this application provides a segmented battery 100, which includes a first segmented battery 111 forming a first pattern assembly 110 and a second segmented battery 121 forming a second pattern assembly 120. That is, referring to... Figure 1 As shown, multiple first-cell battery segments 111 form a first-type assembly 110, see reference. Figure 2 As shown, multiple second-section battery cells 121 are used to form a second-section assembly 120, which enables the power of the first-section assembly 110 and the second-section assembly 120 to be matched after molding.

[0044] Both the first segmented battery 111 and the second segmented battery 121 are cut from the whole battery 200. For example, the whole battery 200 is cut into a certain number of first segmented batteries 111 and a certain number of second segmented batteries 121 by mechanical, laser, or other methods. Furthermore, the first segmented batteries 111 and the second segmented batteries 121 have different sizes. By cutting the whole battery 200 into first segmented batteries 111 and second segmented batteries 121 of different preset sizes, the first segmented battery 111 can form a first pattern assembly 110, and the second segmented battery 121 can form a second pattern assembly 120. That is, the first segmented batteries 111 and the second segmented batteries 121 can form pattern assemblies of different specifications, expanding the pattern manufacturing types of the segmented battery 100. Furthermore, the first segmented battery 100 and the second segmented battery 100 of different sizes are cut from the same whole battery 200. The first segmented battery 111 and the second segmented battery 121 of different sizes can be cut from the same whole battery 200 as required, reducing the number of cuts of the whole battery 200 and reducing the cutting power loss of the first pattern assembly 110 and the second pattern assembly 120 after molding.

[0045] In one embodiment, see Figures 1-3 As shown, along the light-receiving surface parallel to the segmented cell 100 and perpendicular to the cutting direction of the whole cell 200, that is, along Figure 3 In the vertical direction shown, the length of the first segmented battery 111 is L1, and the length of the second segmented battery 121 is L2, where L1 > L2. Thus, by cutting the entire battery 200 to form the relatively large first segmented battery 111 and the relatively small second segmented battery 121, the entire battery 200 can be non-uniformly divided into the first segmented battery 111 and the second segmented battery 121 of different sizes according to the pattern requirements. By rationally planning the number and position of the cuts of the first segmented battery 111 and the second segmented battery 121 on the entire battery 200, the number of cuts of the entire battery 200 can be reduced, thereby reducing the cutting power loss of the first pattern assembly 110 and the second pattern assembly 120 after molding.

[0046] Specifically, see Figure 3 As shown, 1.1L2 ≤ L1 ≤ 2.6L2. L1 can be any of 1.1L2, 1.3L2, 1.5L2, 1.7L2, 1.9L2, 2.1L2, 2.3L2, 2.5L2, or 2.6L2. Of course, in other feasible embodiments, the ratio of L1 to L2 is not limited to the specific values ​​provided above, and can also be other ratio values ​​within the range of 1.1L2 ≤ L1 ≤ 2.6L2.

[0047] Thus, by limiting the ratio of the first segmented battery 111 to the second segmented battery 121 after cutting to 1.1L2≤L1≤2.6L2, based on the size of the whole battery 200 and the size requirements of the first segmented battery 111 and the second segmented battery 121 after cutting, the number of cuttings of the first segmented battery 111 and the second segmented battery 121 on the whole battery 200 can be reasonably planned, reducing the number of cuttings of the whole battery 200 and reducing the cutting power loss of the first molded assembly 110 and the second molded assembly 120 after molding.

[0048] Further, see Figure 3 As shown, 49.5mm ≤ L1 ≤ 149.5mm, and 45mm ≤ L2 ≤ 57.5mm. In specific settings, L1 can be any of 49.5mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, and 149.5mm, and L2 can be any of 45mm, 47mm, 49mm, 51mm, 53mm, 55mm, and 57.5mm. Of course, in other feasible embodiments, L1 can also be other values ​​within the range of 49.5mm to 149.5mm, and L2 can also be other values ​​within the range of 45mm to 57.5mm.

[0049] Thus, by limiting the L1 dimension of the first segmented battery 111 to the range of 49.5mm to 149.5mm and the L2 dimension of the second segmented battery 121 to the range of 45mm to 57.5mm, the number and position of the first segmented battery 111 and the second segmented battery 121 on the whole battery 200 can be reasonably planned, reducing the cutting power loss of the first segmented battery 111 and the second segmented battery 121. The cut first segmented battery 111 and the second segmented battery 121 can be formed into more specifications of template components. In addition to forming traditional even-numbered template components, odd-numbered template components can also be formed, expanding the template component forming specifications of the first segmented battery 111 and the second segmented battery 121.

[0050] If the entire battery 200 is formed into the first segmented battery 111 and the second segmented battery 121 by uniform cutting, to obtain a smaller segmented battery 100, since the smaller segmented battery 100 has cutting edges 130 on both sides, the power loss of the first segmented battery 111 and the second segmented battery 121 after cutting will be too high. Based on this, in one embodiment, see... Figures 1-3 As shown, in the whole battery 200, the first segment battery 111 is located near the middle of the whole battery 200, and the second segment battery 121 is located near the edge of the whole battery 200.

[0051] In this way, by rationally planning the positions of the first segmented battery 111 and the second segmented battery 121 in the whole battery 200, the cutting edge 130 can be concentrated as much as possible on the first segmented battery 111 with larger size. The power loss caused by cutting is relatively small compared to the first segmented battery 111 with larger size, and the cutting edge 130 of the second segmented battery 121 with smaller size is reduced, thereby reducing the cutting power loss of the second segmented battery 121.

[0052] In one embodiment, see Figures 1-3 As shown, both the first segmented battery 111 and the second segmented battery 121 have a cut edge 130 and a cut angle 131 formed by the cut edge 130. The cut angle 131 is located at the corner of the cut first segmented battery 111 and the second segmented battery 112, and is formed by the cut edge 130 and other sides of the first segmented battery 111 or the second segmented battery 112. The cut angle 131 can be any one of a right angle, a rounded corner, or a chamfered corner. For example, see [reference needed]. Figure 4 As shown, when the cutting angle 131 is a right angle, the cutting edge 130 is perpendicular to the side of the first segmented battery 111 or the side of the second segmented battery 121. Since the first segmented battery 111 and the second segmented battery 121 are not chamfered after cutting, there is no need to distinguish the splicing direction of the first segmented battery 111 and the second segmented battery 121 during the splicing process of the first segmented battery 111 forming the first template assembly 110 and the second segmented battery 121 forming the second template assembly 120, thus simplifying the splicing operation of the first template assembly 110 and the second template assembly 120.

[0053] Further, see Figure 5 As shown, when the cutting angle 131 is a rounded corner, the radius of the cutting angle 131 is R, where 0.1mm ≤ R ≤ 0.5mm. Specifically, the radius R of the cutting angle 131 can be any one of 0.1mm, 0.2mm, 0.3mm, 0.4mm, and 0.5mm. Of course, in other feasible embodiments, the radius R of the cutting angle 131 can also be other values ​​within the range of 0.1mm to 0.5mm. Thus, with the small chamfer setting of the first segment battery 111 and the second segment battery 121 after cutting, during the process of splicing the first segment battery 111 to form the first formwork assembly 110 and the second segment battery 121 to form the second formwork assembly 120, it is not necessary to distinguish the splicing direction of the first segment battery 111 and the second segment battery 121, simplifying the splicing operation of the first formwork assembly 110 and the second formwork assembly 120.

[0054] Similarly, see Figure 6As shown, when the cutting angle 131 is a chamfer, the angle of the cutting angle 131 is α, and the cutting angle 131 is formed by two adjacent cutting edges 130, where 0 < α ≤ 30°. Specifically, the angle α of the cutting angle 131 can be any one of 1°, 5°, 10°, 15°, 20°, 25°, and 30°. Of course, in other feasible embodiments, the angle α of the cutting angle 131 can also be other values ​​within the range of 0 to 30°. Thus, with the small chamfer setting of the first segment battery 111 and the second segment battery 121 after cutting, during the process of splicing the first segment battery 111 to form the first formwork assembly 110 and the second segment battery 121 to form the second formwork assembly 120, it is not necessary to distinguish the splicing direction of the first segment battery 111 and the second segment battery 121, simplifying the splicing operation of the first formwork assembly 110 and the second formwork assembly 120.

[0055] It should be noted that, in this embodiment, a passivation layer is formed on the cut edge 130. Passivating the cut edge 130 helps improve the crystal structure matching between the passivation layer and the silicon substrate of the segmented cell 100, reduces the interface state defect density, and saturates the dangling bonds of the silicon substrate, thereby reducing the carrier recombination rate and improving the photoelectric conversion efficiency of the segmented cell 100. The processing technology of the passivation layer on the cut edge 130 is consistent with the prior art and will not be described in detail here.

[0056] In one embodiment, see Figure 1 As shown, multiple first segmented batteries 111 in the first formwork assembly 110 are arranged side-by-side or in a matrix, and the multiple first segmented batteries 111 are connected in parallel or in series. For example, the multiple first segmented batteries 111 are connected in series or in parallel through connectors 140 to realize interconnection, current collection and transmission of the multiple first segmented batteries 111, etc., and the multiple first segmented batteries 111 are arranged side-by-side or in a matrix to form first formwork assemblies 110 of different forms to expand the configuration of the first formwork assembly 110.

[0057] Similarly, see Figure 2 As shown, multiple second-section batteries 121 in the second-model assembly 120 are arranged side-by-side or in a matrix, and the multiple second-section batteries 121 are connected in parallel or in series. For example, the multiple second-section batteries 121 are connected in series or in parallel through connectors 140 to realize interconnection, current collection and transmission of the multiple second-section batteries 121, and the multiple second-section batteries 121 are arranged side-by-side or in a matrix to form second-model assemblies 120 of different models to expand the configuration of the second-model assembly 120.

[0058] In one embodiment, see Figure 3 As shown, the entire battery 200 can be divided into at least one first segmented battery 111 and at least one second segmented battery 121. Exemplarily, as in this embodiment, see [reference needed]. Figure 3 As shown, the entire battery 200 can be cut into one first segment battery 111 and two second segment batteries 121. Before the entire battery 200 is cut, the first segment battery 111 is located near the middle of the entire battery 200, and the two second segment batteries 121 are located near the edge of the entire battery 200. See also other embodiments. Figure 7 As shown, the entire battery 200 can be cut into two first segmented battery pieces 111 and two second segmented battery pieces 121. Before the entire battery 200 is cut, both first segmented battery pieces 111 are located near the center of the entire battery 200, and both second segmented battery pieces 121 are located near the edge of the entire battery 200. As in another embodiment, see [reference needed]. Figure 8 As shown, the entire battery 200 can be divided into three first segmented battery pieces 111 and two second segmented battery pieces 121. Before the entire battery 200 is cut, the three first segmented battery pieces 111 are all located near the center of the entire battery 200, and the two second segmented battery pieces 121 are all located near the edge of the entire battery 200. Alternatively, in some embodiments, see [reference needed]. Figure 9 As shown, the entire battery 200 can be cut into two first segmented batteries 111 and three second segmented batteries 121. Before cutting, the two first segmented batteries 111 are located near the center of the entire battery 200, and the three second segmented batteries 121 are located near the edge of the entire battery 200. This application does not limit the number of first segmented batteries 111 and second segmented batteries 121 that the entire battery 200 can be cut into; the number can be adapted to the specifications of the first molded assembly 110 and the second molded assembly 120 to be formed, as well as the dimensions of the entire battery 200.

[0059] The aforementioned segmented battery 100 reduces the cutting power loss of the first segmented battery 111 and the second segmented battery 121 on the whole battery 200 by rationally planning the number of cuts, and the cut first segmented battery 111 and second segmented battery 121 can be formed into more specifications of template components.

[0060] Additionally, see Figures 1-10 As shown, this application also provides a photovoltaic module 300, which includes at least one segmented cell 100 as described above. By forming photovoltaic modules 300 of different specifications using segmented cells 100, the different power outputs and application scenarios required by the photovoltaic modules 300 can be met.

[0061] Specifically, see Figures 1-10As shown, the photovoltaic module 300 includes multiple cell strings 310, multiple edge busbars 330, multiple center busbars 340, and multiple jumpers 350. Each cell string 310 includes multiple segmented cells 100 connected in series by solder ribbons 320. The cell string 310 can be either a first-type module 110 or a second-type module 120.

[0062] In this embodiment, the width direction of the photovoltaic module 300 is defined as the first direction (i.e., Figure 1 (as shown in the X direction), the length direction of the photovoltaic module 300 is defined as the second direction (i.e., Figure 1 (As shown in the Y direction), the first direction X and the second direction Y are perpendicular to each other. Two battery strings 310 are arranged at intervals along the second direction Y to form a sub-battery string group 360, and two groups of sub-battery string groups 360 are arranged at intervals along the first direction X to form a battery string group 370. The four battery strings 310 in each battery string group 370 can be connected in parallel. Each battery string 310 includes multiple segmented batteries 100, and all segmented batteries 100 of the same battery string 310 are arranged along the second direction Y and can be connected in series. Each intermediate bus bar 340 is located between two battery strings 310 of the same sub-battery string group 360 in the second direction Y, and each intermediate bus bar 340 extends along the first direction X. Each battery string group 370 has an edge bus bar 330 at both opposite ends in the second direction Y, each edge bus bar 330 extends along the first direction X, and the end of each battery string 310 away from the intermediate bus bar 340 is connected to the edge bus bar 330. A portion of the jumper 350 is connected to the edge busbar 330, and another portion is connected to an external device via a junction box. Specifically, in some embodiments, the edge busbar 330, the middle busbar 340, and the jumper 350 are all formed of conductive metal strips.

[0063] For example, see Figure 10 As shown, the photovoltaic module 300 includes three sets of cell strings 370 arranged at intervals along a first direction X. Figure 10 From left to right, they are defined as the first battery string group 371, the second battery string group 372, and the third battery string group 373. Each battery string group 370 includes two sub-cell strings 360 arranged at intervals along the first direction X (i.e., the photovoltaic module 300 includes six sub-cell strings 360). Of course, in other feasible embodiments, the photovoltaic module 300 can also be formed into other types of modules by multiple segmented cells 100. This application does not limit the specific form of the photovoltaic module 300.

[0064] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
