Description

Technical Field

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

[0002] With the development of photovoltaic cell technology, double-glass modules have emerged, consisting of two layers of tempered glass, a reflective film strip, and a cell string module. This not only enhances the mechanical strength of the module but also allows for the transmission of scattered and reflected light, thereby improving power generation efficiency.

[0003] In the traditional manufacturing process of double-glass modules, the inter-string and inter-cell reflective film strips will overlap at their intersections. This can cause uneven pressure on the double-glass module during lamination, and the areas under greater pressure may crack, thus affecting the performance of the double-glass module. Utility Model Content

[0004] Therefore, it is necessary to provide a double-glass module that can reduce the risk of crack formation in order to address the above-mentioned technical problems.

[0005] In a first aspect, this application provides a double-glass module, comprising:

[0006] Front glass;

[0007] Back glass;

[0008] A battery string module is disposed between the front glass and the back glass; a first adhesive film layer is provided between the battery string module and the front glass, and a second adhesive film layer is provided between the battery string module and the back glass; the battery string module includes multiple sets of battery strings arranged along a first direction; each set of battery strings includes multiple battery cells arranged sequentially along a second direction intersecting the first direction;

[0009] Inter-string membrane strips are disposed between adjacent battery strings in the first direction; and

[0010] Inter-cell film strips are disposed between adjacent cells in the second direction; each of the inter-cell film strips does not contact any of the inter-cell film strips.

[0011] In one embodiment, the inter-sheet membrane strip includes a plurality of discontinuous sub-inter-sheet membrane strips, each of which is not in contact with any of the inter-series membrane strips.

[0012] In one embodiment, the inter-string membrane tape includes a plurality of discontinuous sub-inter-string membrane tapes, each of which is not in contact with any of the inter-sheet membrane tapes.

[0013] In one embodiment, the inter-sheet membrane strip includes a plurality of discontinuous sub-inter-sheet membrane strips, and the inter-string membrane strip includes a plurality of discontinuous sub-inter-string membrane strips, wherein no sub-inter-sheet membrane strip is in contact with any sub-inter-string membrane strip.

[0014] In one embodiment, the inter-string membrane strip distance between adjacent sub-strings is less than the inter-sheet membrane strip distance between adjacent sub-sheets.

[0015] In one embodiment, the inter-sheet membrane strip distance between adjacent sub-sheets is less than the inter-string membrane strip distance between adjacent sub-strings.

[0016] In one embodiment, both the inter-string membrane strip and the inter-sheet membrane strip include:

[0017] An adhesive film encapsulation layer that adheres to the back glass;

[0018] A polyester film layer is disposed between the adhesive film encapsulation layer and the reflective layer;

[0019] A reflective layer is disposed between the polyester film layer and the insulating coating; and

[0020] Insulating coating.

[0021] In one embodiment, the insulating coating is adhered to the battery cell.

[0022] In one embodiment, the double-glass assembly further includes a frame disposed around the periphery of the battery string module.

[0023] In one embodiment, the double-glass assembly further includes a junction box;

[0024] The junction box is located at the edge of the double-glass module and is connected to the positive and negative leads of the battery string module via a cable.

[0025] The aforementioned double-glass module includes a front glass and a back glass that together form the outer protective layer of the double-glass module, and a battery string module disposed between the front glass and the back glass. A first adhesive film layer is provided between the battery string module and the front glass, and a second adhesive film layer is provided between the battery string module and the back glass, ensuring strong adhesion between the battery string module and the front and back glass. The battery string module includes multiple sets of battery strings arranged along a first direction, and each set of battery strings includes multiple battery cells arranged sequentially along a second direction intersecting the first direction. Furthermore, the double-glass module also includes inter-string film strips disposed between adjacent battery strings in the first direction and inter-cell film strips disposed between adjacent battery cells in the second direction. Since no inter-string film strip contacts any inter-cell film strip, there is no overlap between any inter-string film strip and any inter-cell film strip. During the lamination process of the double-glass module, the module is subjected to uniform stress, thereby reducing the risk of cracking and improving the performance of the double-glass module.

Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0041] As described in the background section, in the traditional manufacturing process of double-glass modules, the inter-string and inter-cell reflective film strips will overlap at their intersections. This can lead to uneven pressure on the double-glass module during lamination, and the areas under greater pressure may develop cracks, thus affecting the performance of the double-glass module.

[0042] For the reasons mentioned above, such as Figure 1 As shown, this application provides a double-glass module, including: a front glass 10; a back glass 50; a battery string module 30 disposed between the front glass 10 and the back glass 50; a first adhesive film layer 20 is provided between the battery string module 30 and the front glass 10, and a second adhesive film layer 40 is provided between the battery string module 30 and the back glass 50; the battery string module 30 includes multiple sets of battery strings arranged along a first direction; each set of battery strings includes multiple battery cells arranged sequentially along a second direction intersecting the first direction; inter-string film strips (not shown in the figure) are disposed between adjacent battery strings in the first direction; and inter-cell film strips (not shown in the figure) are disposed between adjacent battery cells in the second direction; any inter-string film strip and any inter-cell film strip do not contact each other.

[0043] The front glass 10 is the outermost layer of the double-glass module, located on the front side and directly exposed to the external environment. It is typically made of tempered glass with high light transmittance, offering good light transmission and mechanical strength to protect the internal cell string module 30 from environmental damage. The back glass 50 is the inner layer of the double-glass module, located on the back side and tightly fitted to the cell string module 30. It is also made of tempered glass, providing stable support and protection for the cell string module 30, preventing deformation or damage to the cells under external forces. The cell string module 30 is the core component of the double-glass module, consisting of multiple sets of cells arranged along a first direction. These cell strings are connected by wires to form a circuit responsible for converting solar energy into electrical energy. A first adhesive film layer 20 is placed between the cell string module 30 and the front glass 10 to bond them together. It is typically made of ethylene-vinyl acetate copolymer or polyvinyl butyral, offering good adhesion and weather resistance. The second adhesive film layer 40 is disposed between the battery string module 30 and the back glass 50 to bond the back glass 50 and the battery string module 30. Similar to the first adhesive film layer 20, it is also made of adhesive film material to ensure a tight bond between the battery string module 30 and the back glass 50.

[0044] A battery string is the basic unit of the battery string module 30, consisting of multiple battery cells arranged sequentially along a second direction intersecting the first direction. These battery cells are connected in series by wires to form a single battery string. A battery cell is the basic unit of a solar cell, responsible for converting solar energy into electrical energy. In a battery string, multiple battery cells are connected by wires to form the battery string. An inter-string film 60 is disposed between adjacent battery strings in the first direction to isolate and protect adjacent battery strings. It is typically made of a material with certain insulation and weather resistance to prevent short circuits or mutual interference between adjacent battery strings. An inter-cell film 70 is disposed between adjacent cells in the second direction to isolate and protect adjacent cells. Similar to the inter-string film 60, it is also made of a material with certain insulation and weather resistance to ensure electrical isolation and mechanical stability between adjacent cells. Optionally, the first and second directions intersect; for example, the first and second directions can intersect perpendicularly or obliquely.

[0045] Specifically, the front glass 10, serving as the front barrier of the double-glass module, is made of high-transmittance, high-strength tempered glass, effectively resisting external environmental disturbances such as wind, sand, and rain, while ensuring unobstructed sunlight penetration to provide ample and uniform illumination for the internal battery string module 30. The back glass 50, located on the back of the module, echoes the front glass 10 and also uses high-quality tempered glass, providing robust support and protection for the battery string module 30, effectively preventing mechanical damage and moisture intrusion, and ensuring the long-term stable operation of the module. Between the front glass 10 and the back glass 50, the battery string module 30, the core power generation component of the double-glass module, is cleverly positioned. The battery string module 30 consists of multiple sets of battery strings arranged in an orderly manner along a first direction (such as the horizontal direction). Each set of battery strings has been carefully laid out and optimized to ensure optimal power generation efficiency and performance. Each battery string consists of multiple battery cells arranged sequentially along a second direction (such as a perpendicular direction) intersecting the first direction. These battery cells are connected in series using advanced connection technology to form a highly efficient and stable power generation unit. To enhance the adhesion and sealing between the battery string module 30 and the front glass 10 and the back glass 50, a first adhesive film layer 20 is provided between the battery string module 30 and the front glass 10, and a second adhesive film layer 40 is provided between the battery string module 30 and the back glass 50. These two adhesive films are made of high-quality materials and have excellent adhesion, sealing, and weather resistance, ensuring that the battery string module 30 is firmly adhered to the front glass 10 and the back glass 50, while preventing moisture and gas penetration and protecting the battery string module 30 from corrosion and damage.

[0046] Furthermore, to further improve the reliability and safety of the module, inter-string film strips 60 are installed between adjacent cell strings in the first direction, and inter-cell film strips 70 are installed between adjacent cells in the second direction. These film strips are made of special insulating materials, possessing excellent insulation performance and weather resistance, effectively isolating current between adjacent cell strings and cells to prevent short circuits. Simultaneously, each inter-string film strip 60 and each inter-cell film strip 70 remains in contact with each other, avoiding mutual interference and influence between the film strips. This ensures improved reflective film application efficiency while preventing microcracks between cells caused by the film strips, and also avoids short circuits caused by the film strips, ensuring a more uniform and stable current distribution within the module.

[0047] The aforementioned double-glass module includes a front glass 10 and a back glass 50 that together form the outer protective layer of the double-glass module, and a battery string module 30 disposed between the front glass 10 and the back glass 50. A first adhesive film layer 20 is provided between the battery string module 30 and the front glass 10, and a second adhesive film layer 40 is provided between the battery string module 30 and the back glass 50, which can ensure the strong adhesion between the battery string module 30 and the front glass 10 and the back glass 50. The battery string module 30 includes multiple sets of battery strings arranged along a first direction, and each set of battery strings includes multiple battery cells arranged sequentially along a second direction intersecting the first direction. In addition, the double-glass module also includes an inter-string film strip 60 disposed between adjacent cell strings in the first direction and an inter-cell film strip 70 disposed between adjacent cell strings in the second direction. Since any inter-string film strip 60 and any inter-cell film strip 70 do not contact each other, there will be no crossover between any inter-string film strip 60 and any inter-cell film strip 70. During the lamination process of the double-glass module, the module is subjected to uniform stress, thereby reducing the risk of cracking and improving the performance of the double-glass module.

[0048] In one embodiment, the inter-sheet membrane strip 70 includes a plurality of discontinuous sub-inter-sheet membrane strips, each of which is not in contact with any of the inter-sheet membrane strips 60.

[0049] Specifically, the inter-laminar film strip 70 includes multiple discontinuous sub-inter-laminar film strips, none of which are in contact with any inter-string film strip 60, ensuring that the film strips do not cross-stack. The inter-string film strip 60 is completely separated from the inter-laminar film strip 70. Since the film strips do not stack, stress is no longer concentrated, and the stress distribution is more uniform. Furthermore, the inter-laminar film strip 70 is not a long strip as in the prior art that runs through the battery string; therefore, even if the solder ribbon punctures the film strip in subsequent processes, a short circuit will not occur between the battery strings. Optionally, as... Figure 2As shown, the inter-plate membrane strip 70 includes two discontinuous sub-inter-plate membrane strips 71 and 72. The two sub-inter-plate membrane strips 71 and 72 are located on one side and the other side of the inter-tandem membrane strip 60 in the figure, respectively, and the two sub-inter-plate membrane strips 71 and 72 are spaced apart from the inter-tandem membrane strip 60 in the figure and do not contact each other.

[0050] In this embodiment, the inter-cell film strip 70 includes multiple discontinuous sub-inter-cell film strips 71 and 72. Each sub-inter-cell film strip does not contact any inter-string film strip 60. On the one hand, this ensures that the inter-string film strip 60 and the inter-cell film strip 70 do not intersect and therefore do not stack. As a result, the pressure on the double-glass module is uniform during the lamination process, avoiding cracks in the double-glass module during lamination. On the other hand, the inter-cell film strip 70 is not a long strip that runs through the battery string as in the prior art. Therefore, even if the solder ribbon punctures the film strip in the subsequent process, a short circuit will not occur between the battery strings.

[0051] In one embodiment, the inter-string membrane strip 60 includes a plurality of discontinuous sub-inter-string membrane strips, each of which is not in contact with any one inter-string membrane strip 70.

[0052] Specifically, the inter-string film strip 60 includes multiple discontinuous sub-inter-string film strips, each of which does not contact any inter-sheet film strip 70, ensuring that the film strips do not cross-stack. The inter-string film strip 60 and the inter-sheet film strip 70 are completely separated. Since the film strips do not stack, stress is no longer concentrated, and the stress distribution is more uniform. Furthermore, the inter-string film strip 60 is not a long strip as in existing technologies that penetrates the solar cell; therefore, even if the solder ribbon punctures the film strip in subsequent processes, short circuits will not occur between the solar cells. Optionally, as... Figure 3 As shown, the inter-string membrane strip 60 includes two discontinuous sub-inter-string membrane strips 61 and 62. The two sub-inter-string membrane strips 60 are located on one side and the other side of the inter-sheet membrane strip 70 in the figure, respectively, and the two sub-inter-string membrane strips 61 and 62 are spaced apart from the inter-sheet membrane strip 70 in the figure and do not contact each other.

[0053] In this embodiment, the inter-string film strip 60 includes multiple discontinuous sub-inter-string film strips, and each sub-inter-string film strip does not contact any inter-sheet film strip 70. On the one hand, this ensures that the inter-string film strip 60 and the inter-sheet film strip 70 do not intersect and therefore do not stack. As a result, the pressure on the double-glass module is uniform during the lamination process, avoiding cracks in the double-glass module during lamination. On the other hand, the inter-string film strip 60 is not a long strip that penetrates through the solar cells as in the prior art. Therefore, even if the solder ribbon pierces the film strip in subsequent processes, short circuits will not occur between the solar cells.

[0054] In one embodiment, the inter-sheet membrane strip 70 includes a plurality of discontinuous sub-inter-sheet membrane strips, and the inter-string membrane strip 60 includes a plurality of discontinuous sub-inter-string membrane strips, wherein no sub-inter-sheet membrane strip is in contact with any sub-inter-string membrane strip.

[0055] Specifically, the inter-cell membrane strip 70 includes multiple discontinuous sub-inter-cell membrane strips, and the inter-string membrane strip 60 includes multiple discontinuous sub-inter-string membrane strips. No sub-inter-cell membrane strip is in contact with any sub-inter-string membrane strip, which also ensures that the inter-string membrane strip 60 and the inter-cell membrane strip 70 will not cross each other and will not stack. Therefore, the pressure on the double-glass module is uniform during the lamination process, avoiding cracks in the double-glass module during the lamination process.

[0056] In some specific embodiments, in order to ensure the insulation performance of inter-sheet film strips and inter-string film strips while preventing them from crossing, the inter-string film strip distance between adjacent sub-string film strips can be set to be smaller than the inter-sheet film strip distance between adjacent sub-sheet film strips.

[0057] In some other specific embodiments, the inter-sheet membrane strip distance between adjacent sub-sheets can be set to be smaller than the inter-string membrane strip distance between adjacent sub-strings.

[0058] In one embodiment, the inter-string membrane strip distance between adjacent sub-strings is less than the inter-sheet membrane strip distance between adjacent sub-sheets.

[0059] Specifically, such as Figure 4 As shown, the distance between the inter-string membrane strips 61 and 62 of adjacent sub-strings is set to be less than the distance between the inter-sheet membrane strips 71 and 72 of adjacent sub-sheets. This ensures that the inter-sheet membrane strip 70 and the inter-string membrane strip 60 do not cross each other, while ensuring the insulation performance of the inter-sheet membrane strip 70 and the inter-string membrane strip 60.

[0060] In one embodiment, the inter-sheet membrane strip distance between adjacent sub-sheets is less than the inter-string membrane strip distance between adjacent sub-strings.

[0061] Specifically, such as Figure 5 As shown, the inter-sheet film strip distance between adjacent sub-sheet film strips 71 and 72 is set to be less than the inter-string film strip distance between adjacent sub-string film strips 61 and 62. This ensures that the inter-sheet film strip 70 and the inter-string film strip 60 do not cross each other while ensuring the insulation performance of the inter-sheet film strip 70 and the inter-string film strip 60.

[0062] In one embodiment, both the inter-episode film strip 60 and the inter-sheet film strip 70 include (in this embodiment, the inter-episode film strip 60 is used as an example): an adhesive film encapsulation layer 63 that is bonded to the back glass 50; a polyester film layer 64 disposed between the adhesive film encapsulation layer 63 and the reflective layer 65; the reflective layer 65 disposed between the polyester film layer 64 and the insulating coating layer 66; and the insulating coating layer 66.

[0063] The EVA (Ethylene-Vinyl Acetate Copolymer) encapsulation layer is an adhesive or sealant layer used to bond different materials together or to provide a protective encapsulation to prevent moisture, dust, or other contaminants from entering. In this embodiment, the EVA encapsulation layer 63 is used to bond the inter-layer film strip 60 or the inter-sheet film strip 70 to the back glass 50 or the front glass 10.

[0064] The polyester film layer 64 is a transparent or semi-transparent film made of polyester resin, possessing good mechanical properties, chemical stability, and weather resistance. In a multilayer structure, it may serve as a substrate for an insulating layer, protective layer, or reflective layer. The polyester film, a transparent or semi-transparent film made of polyester resin, is used in this embodiment as a flame-retardant insulating material. The reflective layer is a material layer capable of reflecting light, typically used to improve light utilization or change the direction of light propagation. In this embodiment, the reflective layer is used to reflect light that is not directly absorbed by the solar cell back to the solar cell, thereby improving photoelectric conversion efficiency. The insulating coating is a material layer with electrical insulating properties, used to prevent current from flowing where it is not needed or to prevent electrical contact between different layers. In a multilayer structure, it is used to protect electronic components, prevent short circuits, or provide an additional safety barrier.

[0065] Specifically, such as Figure 6 As shown, the EVA encapsulation layer can be bonded to the back glass 50 by melting it at high temperature; the PET (Polyethylene terephthalate) polyester film layer serves as a flame-retardant insulating material in this embodiment. Optionally, sunlight shines through the gaps between the battery strings and cells onto the reflective layer, then is reflected by the reflective layer onto the glass, and finally reflected by the glass onto the battery cells. The reflective layer can be either insulating or non-insulating; insulating layers are too expensive, so non-insulating materials are generally used.

[0066] In this embodiment, both the inter-string film strip 60 and the inter-cell film strip 70 include an encapsulation layer, a polyester film layer, a reflective layer, and an insulating coating, which can improve the power generation and stability of the double-glass module and reduce maintenance costs.

[0067] In one embodiment, an insulating coating is bonded to the battery cell.

[0068] Specifically, the insulating coating adheres to the battery cells, which can effectively isolate the conductive parts between the battery cells / strings and prevent short circuits caused by direct contact between battery cells / strings or the intrusion of foreign objects.

[0069] In one embodiment, the double-glass module also includes a frame disposed around the battery string module.

[0070] Specifically, the double-glass module also includes a frame surrounding the battery string module, providing additional physical protection against mechanical damage such as impacts and scratches during transportation, installation, and use. Furthermore, a sealed structure is formed between the frame and the glass to prevent moisture, dust, and other external substances from entering the module, protecting the battery string module from corrosion.

[0071] In one embodiment, the double-glass module further includes a junction box; the junction box is disposed in the edge region of the double-glass module and is connected to the positive and negative leads of the battery string module via cables.

[0072] The junction box is an important electrical component in photovoltaic modules. It is usually installed on the back of the module, near the positive and negative leads of the cell string.

[0073] Specifically, the junction box is located at the edge of the double-glass module and is connected to the positive and negative leads of the battery string module 30 via cables, which reduces current loss during transmission and improves the power generation efficiency of the double-glass module.

[0074] In a specific embodiment, such as Figure 7 The model shows the back glass panel layout, with horizontal strips for inter-series films and vertical strips for inter-cell films. The solar cells are placed in the middle of the strips, with the corners and intersections in contact. The ends of the inter-cell film strips are more than 0 mm from the ends of the inter-series film strips (the ends of the film strips shrink to some extent during the lamination process, which increases the distance between the film strips).

[0075] In this embodiment, the inter-series and inter-sheet membrane tapes no longer overlap; the inter-series and inter-sheet membrane tapes are completely separated, and the tape height is 105 μm. Since the tapes do not overlap, as... Figure 8 and Figure 9 As shown, the edges of the battery cells in the battery string module 30 are uniformly pressed together with the inter-string film strip 60 and the inter-cell film strip 70, so the stress on the edges is no longer concentrated and the force is more uniform.

[0076] 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 application.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this 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 application should be determined by the appended claims.
