Description

Technical Field

[0001] This application relates to the field of solar cell technology, specifically to solar photovoltaic module packaging devices and photovoltaic modules. Background Technology

[0002] Film lamination is a crucial step in the manufacturing of solar photovoltaic modules. It involves bonding photovoltaic cells to an upper glass layer and a lower backsheet under vacuum conditions with an encapsulating film material through heating and pressurization to form a permanent sealed structure. This process relies primarily on the adhesiveness and sealing properties of the encapsulating film to protect the cells and ensure the long-term stability and performance of the solar photovoltaic module.

[0003] Currently, solar photovoltaic modules are typically encapsulated using laminated encapsulating films such as EVA, POE, and PVB. Extensive use of encapsulating films can lead to high costs associated with film separation and is detrimental to the later maintenance and recycling of solar photovoltaic modules.

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a solar photovoltaic module encapsulation device and a photovoltaic module that can reduce the amount of encapsulating film used, reduce the separation cost of encapsulating film and solar photovoltaic module, and facilitate the later maintenance and recycling of solar photovoltaic module.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A solar photovoltaic module encapsulation device, comprising:

[0008] Front glass;

[0009] Rear glass panel;

[0010] An encapsulating film is disposed at intervals on the surface of the front glass panel; and / or, the encapsulating film is disposed at intervals on the surface of the rear glass panel;

[0011] An elastic gasket is disposed between the front glass panel and the rear glass panel;

[0012] The front glass panel and the rear glass panel are bonded and sealed together by the encapsulating film, forming a sealed chamber between the front glass panel and the rear glass panel for encapsulating the battery cells.

[0013] In some embodiments, the shape of the elastic pad is selected from one or more of square, circular, T-shaped, cross-shaped, and L-shaped.

[0014] In some embodiments, the thickness of the elastic pad is greater than the thickness of the battery cell.

[0015] In some embodiments, the front glass panel is provided with a groove for placing the elastic gasket;

[0016] And / or, the rear glass panel is provided with a groove for placing the elastic gasket.

[0017] In some embodiments, a second groove is provided on the front glass panel for placing the battery cell;

[0018] And / or, the rear glass panel is provided with a second groove for placing the battery cell.

[0019] In some embodiments, the front glass and / or the rear glass are provided with vents;

[0020] The vent is used to fill and release air into the sealed chamber formed between the front glass and the rear glass for encapsulating the battery cells.

[0021] In some embodiments, the pores are fitted with an openable and closable sealing plug.

[0022] In some embodiments, the front glass panel is provided with a break groove;

[0023] And / or, the rear glass panel is provided with a breakage groove.

[0024] In some embodiments, when the breakout groove is disposed on the front glass panel, the depth of the breakout groove does not exceed 30% of the thickness of the front glass panel.

[0025] And / or, when the breakout groove is provided on the rear glass panel, the depth of the breakout groove does not exceed 30% of the thickness of the rear glass panel.

[0026] This application also provides a solar photovoltaic module, including: a solar photovoltaic module;

[0027] The solar photovoltaic module is sealed and encapsulated within the solar photovoltaic module encapsulation device described above.

[0028] In this technical solution, an elastic gasket is set between the front and rear glass panels. The solar cells are sealed by the combined action of the elastic gasket, encapsulating film, front glass, and rear glass. In other words, encapsulating film can be omitted or used in only a small amount at the location where the elastic gasket is covered. The elastic gasket partially replaces the encapsulating film, thereby reducing the amount of encapsulating film used. This not only reduces the material cost of the encapsulating film and the weight of the solar photovoltaic module, but also reduces the separation cost of the encapsulating film and the solar photovoltaic module, which is beneficial for the later maintenance and recycling of the solar photovoltaic module.

[0044] This application aims to provide a solar photovoltaic module encapsulation device and a photovoltaic module. An elastic gasket 2 is provided between the front glass 1 and the rear glass 3. The solar cells 4 are sealed by the combined action of the elastic gasket 2, the encapsulating film 6, the front glass 1, and the rear glass 3. That is, the encapsulating film 6 can be omitted or used in only a small amount at the location covering the elastic gasket 2, as the elastic gasket 2 partially replaces the encapsulating film 6. This reduces the amount of encapsulating film 6 used, lowering the material cost of the encapsulating film 6, reducing the weight of the solar photovoltaic module, and lowering the separation cost of the encapsulating film 6 and the solar photovoltaic module. This is beneficial for the later maintenance and recycling of the solar photovoltaic module.

[0045] This application provides a solar photovoltaic module encapsulation device, including:

[0046] Front glass 1;

[0047] Rear glass 3;

[0048] An encapsulating film 6 is disposed at intervals on the surface of the front glass panel 1; and / or, the encapsulating film 6 is disposed at intervals on the surface of the rear glass panel 3;

[0049] An elastic gasket 2 is disposed between the front glass panel 1 and the rear glass panel 3;

[0050] The front glass panel 1 and the rear glass panel 3 are bonded and sealed by the encapsulating film 6, forming a sealed chamber between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cell 4.

[0051] In this embodiment, the solar photovoltaic module encapsulation device is used to seal and encapsulate the solar cell 4; the solar cell 4 and the elastic gasket 2 are placed on the corresponding positions of the back glass 3 (the placement of the elastic gasket 2 should be close to the solar cell 4 to facilitate the fixing of the solar cell 4 and not to block or hinder the light absorption of the solar cell 4; it can be as follows). Figures 1-2 As shown, the elastic gasket 2 is placed around the outside of the battery cell 4, and the elastic gasket 2 is made to fit the four corners of the battery cell 4. Then, the front glass 1 is covered, and the position where the encapsulating film 6 is placed is heated to help the encapsulating film 6 cure. Under the combined action of the front glass 1, the rear glass 3, the encapsulating film 6 and the elastic gasket 2, a sealing structure for encapsulating the battery cell 4 is formed.

[0052] In this embodiment, the material of the elastic gasket 2 can be selected from natural rubber, nitrile rubber, neoprene rubber, and other rubber materials; the material of the elastic gasket 2 can also be selected from plastic film materials with good elasticity and flexibility. The number of elastic gaskets 2 can be one or multiple pieces. The number of elastic gaskets 2 and the area of ​​each elastic gasket 2 are set according to actual needs. The purpose is to replace part of the encapsulating film 6 to complete the seal between the front glass 1 and the rear glass 3, thereby reducing the amount of encapsulating film 6 used and reducing the difficulty of separating the front glass 1 and the rear glass 3. The encapsulating film 6 can be set on the front glass 1, or on the rear glass 3, or both the front glass 1 and the rear glass 3 can be provided with encapsulating film 6, as long as the encapsulating film 6 can effectively bond the front glass 1 and the rear glass 3 to form a sealed structure for encapsulating the battery cell 4. The number of encapsulating films 6 can be set according to actual needs.

[0053] In this embodiment, the front glass 1 needs to ensure the light absorption effect of the battery cell 4, and the rear glass 3 needs to provide stable support. The material and thickness of the front glass 1 and the rear glass 3 can be selected according to parameters such as temperature resistance, weather resistance, flexibility and transparency.

[0054] In this embodiment, the solar photovoltaic module encapsulation device is used to seal and encapsulate the solar photovoltaic module, which simplifies the encapsulation process, eliminates the need for an expensive laminator, and reduces encapsulation time. Furthermore, this solar photovoltaic module encapsulation device is suitable for various types of solar cells, especially heterojunction cells that are sensitive to high moisture content. It also simplifies the separation process of the solar photovoltaic module, reduces the consumption of manpower and resources, and thus lowers the recycling cost of the solar photovoltaic module.

[0055] In this embodiment, an elastic gasket 2 is provided between the front glass 1 and the rear glass 3. The sealing of the battery cell 4 is completed by the combined action of the elastic gasket 2, the encapsulating film 6, the front glass 1, and the rear glass 3. That is, the encapsulating film 6 can be omitted or used in a small amount at the position covering the elastic gasket 2. The elastic gasket 2 partially replaces the encapsulating film 6, thereby reducing the amount of encapsulating film 6 used. This not only reduces the material cost of the encapsulating film 6 and the weight of the solar photovoltaic module, but also reduces the separation cost of the encapsulating film 6 and the solar photovoltaic module, which is beneficial for the later maintenance and recycling of the solar photovoltaic module.

[0056] In some embodiments, the shape of the elastic pad 2 is selected from one or more of the following: square, circular, T-shaped, cross-shaped, and L-shaped. For details, please refer to... Figures 1-3 .

[0057] In this embodiment, the shape of the elastic gasket 2 is optimized so that the elastic gasket 2 fits the battery cell 4 better, which is conducive to forming a more stable sealing structure between the front glass 1 and the rear glass 3 for encapsulating the battery cell 4.

[0058] In some embodiments, the thickness of the elastic pad 2 is greater than the thickness of the battery cell 4.

[0059] In this embodiment, the thickness of the elastic gasket 2 is greater than the thickness of the solar cell 4. On the one hand, the elastic deformation of the elastic gasket 2 can be used to form a more stable sealing structure between the front glass 1 and the rear glass 3 for encapsulating the solar cell 4. On the other hand, it can also help reduce the amount of encapsulating film 6 used and reduce the separation cost of encapsulating film 6 and solar photovoltaic module.

[0060] In some embodiments, the front glass panel 1 is provided with a first groove 8 for placing the elastic pad 2;

[0061] And / or, the rear glass panel 3 is provided with a first groove 8 for placing the elastic gasket 2.

[0062] In this embodiment, a first groove 8 is provided to facilitate the placement of the elastic gaskets 2. When the battery cell 4 is placed between the elastic gaskets 2, the clamping force generated by the elastic deformation between the elastic gaskets 2 can be used to fix the battery cell 4, making it easier to form a more stable sealing structure for encapsulating the battery cell 4. The first groove 8 is positioned in the same way as the encapsulating film 6. It can be set on the front glass 1, on the rear glass 3, or both the front glass 1 and the rear glass 3 can have the first groove 8. The position of the first groove 8 can be set as needed. For the specific structure of the first groove 8, please refer to [reference needed]. Figure 4 , Figure 5 .

[0063] In this embodiment, a first groove 8 is designed at the position corresponding to the placement of the elastic pad 2. This groove can be formed during the glass pressing process to assist in the positioning of the elastic pad 2. The design of this first groove 8 is not mandatory and can be adjusted according to actual production needs. Considering the possibility of microcracks in the battery, two placement schemes are also designed for the battery cell 4: the battery cell 4 can be placed on the elastic pad 2 and / or between the elastic pad 2. The elastic deformation range of the elastic pad 2 can be designed in advance to fix the battery cell 4.

[0064] In some embodiments, the front glass 1 is provided with a second groove 9 for placing the battery cell 4;

[0065] And / or, the rear glass panel 3 is provided with a second groove 9 for placing the battery cell 4.

[0066] In this embodiment, a second groove 9 is provided to facilitate the placement of the battery cell 4. Placing the battery cell 4 within the second groove 9 facilitates the formation of a more stable sealing structure for encapsulating the battery cell 4. The second groove 9 is positioned similarly to the encapsulating film 6; it can be positioned on the front glass 1, the rear glass 3, or both the front and rear glass 3 may have the second groove 9. The position of the second groove 9 can be determined as needed. For the specific structure of the second groove 9, please refer to [reference needed]. Figure 6 , Figure 7 .

[0067] In this embodiment of the application, a second groove 9 is designed at the position corresponding to the placement of the battery cell 4. It can be made during the glass pressing process to assist in the positioning of the battery cell 4. The design of this second groove 9 is not mandatory and can be adjusted according to actual production needs.

[0068] In some embodiments, the front glass panel 1 and / or the rear glass panel 3 are provided with vents 5;

[0069] The vent 5 is used to fill and release air into the sealed chamber formed between the front glass 1 and the rear glass 3 for encapsulating the battery cell 4.

[0070] In this embodiment, vents 5 are provided. The solar cell 4 and elastic gasket 2 are placed on the corresponding positions of the rear glass 3, and then the front glass 1 is covered. Heating is applied to the area where the encapsulating film 6 is placed to aid in its curing. Under the combined action of the front glass 1, rear glass 3, encapsulating film 6, and elastic gasket 2, a sealed structure for encapsulating the solar cell 4 is formed. A vacuum is then created through the vents 5 to further solidify the seal. Additionally, when subsequent maintenance and recycling of the solar photovoltaic module are required, the vents 5 can be opened, and the front glass 1 and rear glass 3 are no longer sealed, facilitating the disassembly of the solar photovoltaic module. The location of the vents 5 can be selected according to actual needs. Specifically, the vents 5 can be positioned as follows: Figure 1 , Figure 2 , Figure 3 As shown.

[0071] In this embodiment of the application, at the end of the life cycle of the solar photovoltaic module, the various parts of the module are separated by opening the vent 5. This method can maintain the structural integrity of each component of the solar photovoltaic module and improve the later recycling and reuse value of the solar photovoltaic module materials.

[0072] In this embodiment, based on the easy disassembly of the solar photovoltaic module encapsulation device, the solar photovoltaic module can be opened after encapsulation. In the event of damage to individual components, the solar photovoltaic module encapsulation device can be disassembled first, the corresponding components replaced, and then re-encapsulated. This greatly reduces the subsequent maintenance costs of the solar photovoltaic module.

[0073] In some embodiments, the vent 5 is fitted with an openable and closable sealing plug. In this embodiment, the sealing plug facilitates the inflation and deflation of the sealed chamber formed between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cell 4, making it highly practical.

[0074] In some embodiments, the front glass panel 1 is provided with a break groove 7;

[0075] And / or, the rear glass panel 3 is provided with a breakage groove 7.

[0076] In this embodiment, the breaking groove 7 can serve as a separation point, facilitating the rapid separation of the front glass 1 and the rear glass 3. During the recycling of the solar photovoltaic module, the integrity of the internal structure of the solar photovoltaic module can be maintained, preventing damage to the internal components. The shape (can be cylindrical, rectangular, dot-shaped, or triangular prism-shaped), width, depth, and distance from the edge of the front glass 1 and the rear glass 3 of the breaking groove 7 are determined according to the specific module design, and can be as follows: Figure 8As shown. The manufacturing method of the breakage groove 7 can be set according to production needs, such as using laser grooving, glass grinding, glass cutting scraper, etc. At the end of the life cycle of the solar photovoltaic module, by applying lateral and / or longitudinal forces at the location of the breakage groove 7, and by utilizing the thermal stress brought about by the local high temperature cooling of the breakage groove 7 to increase the brittleness of the glass, the edge connection of the front glass 1 / rear glass 3 can be separated from the main body. This can maintain the overall integrity of the front glass 1 / rear glass 3 and the integrity of other internal structures, thereby improving the later recycling and reuse value of the solar photovoltaic module. For solar photovoltaic modules with aluminum frames, the aluminum frame of the solar photovoltaic module should cover the breakage groove 7 as much as possible to protect the breakage groove 7 from breakage caused by impact. The specific structure of the breakage groove 7 can be found in [reference needed]. Figures 4-7 .

[0077] In some embodiments, when the breakage groove 7 is disposed on the front glass panel 1, the depth of the breakage groove 7 does not exceed 30% of the thickness of the front glass panel 1;

[0078] And / or, when the breakage groove 7 is provided on the rear glass panel 3, the depth of the breakage groove 7 does not exceed 30% of the thickness of the rear glass panel 3. In the technical solution of this application, controlling the depth of the breakage groove 7 can protect the front glass panel 1 / rear glass panel 3 from breakage caused by impact.

[0079] The following specific embodiments provide a more detailed description of this application, but should not be construed as limiting the application. Any modifications or substitutions made to the methods, steps, or conditions of this application without departing from the spirit and substance of this application are within the scope of this application.

The rear glass panel 3 is provided with a breakage groove 7, and the depth of the breakage groove 7 on the rear glass panel 3 is 20% of the thickness of the rear glass panel 3.

[0085] An elastic gasket 2 is disposed between the front glass panel 1 and the rear glass panel 3; a battery cell 4 is also disposed between the front glass panel 1 and the rear glass panel 3; specifically, there are multiple battery cells 4, which are arranged in an array on the rear glass panel 3, and an elastic gasket 2 is disposed at each of the four corners of each battery cell 4, which fits against the corners of the battery cell 4; the elastic gasket 2 is square, which makes the elastic gasket 2 fit more closely to the battery cell 4, which is conducive to forming a more stable sealing structure between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cell 4; the thickness of the elastic gasket 2 is 1.2 times the thickness of the battery cell 4;

[0086] The front glass panel 1 and the rear glass panel 3 are bonded and sealed by the encapsulating film 6, forming a sealed chamber between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cell 4.

[0087] Example 2

[0088] Solar photovoltaic module encapsulation devices, such as Figure 6 , Figure 7 As shown, it includes:

[0089] Front glass panel 1; the front glass panel 1 is provided with vents 5; the vents 5 are used to fill and release air into the sealed chamber formed between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cells 4; the vents 5 are matched with openable and closable sealing plugs; the front glass panel 1 is provided with a breakage groove 7, the depth of the breakage groove 7 on the front glass panel 1 is 20% of the thickness of the front glass panel 1;

[0090] The rear glass panel 3 is provided with a second groove 9 for placing the battery cell 4; the second groove 9 facilitates the placement of the battery cell 4; the rear glass panel 3 is provided with a breakage groove 7, the depth of which is 20% of the thickness of the rear glass panel 3.

[0091] Encapsulating film 6, which is spaced apart on the surface of the back glass 3;

[0092] An elastic gasket 2 is disposed between the front glass panel 1 and the rear glass panel 3; a battery cell 4 is also disposed between the front glass panel 1 and the rear glass panel 3; specifically, there are multiple battery cells 4, which are arranged in an array on the rear glass panel 3, and an elastic gasket 2 is disposed at each of the four corners of each battery cell 4, which fits against the corner of the battery cell 4; the elastic gasket 2 is square, and a more stable sealing structure for encapsulating the battery cell 4 is formed between the front glass panel 1 and the rear glass panel 3;

[0093] The front glass panel 1 and the rear glass panel 3 are bonded and sealed by the encapsulating film 6, forming a sealed chamber between the front glass panel 1 and the rear glass panel 3 for encapsulating the battery cell 4.

[0094] The method of using the solar photovoltaic module encapsulation device is as follows: place the solar cell 4 and the elastic gasket 2 on the corresponding positions of the back glass 3, then cover the front glass 1, and heat the position where the encapsulation film 6 is placed to assist the encapsulation film 6 in curing. Under the combined action of the front glass 1, the back glass 3, the encapsulation film 6 and the elastic gasket 2, a sealed structure for encapsulating the solar cell 4 is formed. Then, a vacuum is drawn through the air hole 5 to form the sealed structure. Due to the air pressure, the front glass 1 and the back glass 3 will form pressure inside the solar cell 4, pressing the elastic gasket 2, thereby fixing the position of the solar cell 4. At the same time, a vacuum cavity is formed inside the solar cell 4. Closing the air hole 5 completes the encapsulation, which facilitates the formation of a more stable sealed structure for encapsulating the solar cell 4. Furthermore, when subsequent maintenance and recycling of the solar photovoltaic modules are required, the vent 5 can be opened, and the front glass 1 and rear glass 3 will no longer be sealed. Simultaneously, the breakage groove 7 can be used as a separation point. Lateral and / or longitudinal forces can be applied at the breakage groove 7 to separate the edge connection of the front glass 1 / rear glass 3 from the main body, facilitating the disassembly of the solar photovoltaic module. This process maintains the overall integrity of the front glass 1 / rear glass 3 and other internal structures, enhancing the later recycling and reuse value of the solar photovoltaic module. Later recycling: The performance of the solar cells 4 is tested using methods such as electrical performance testing. The recycled solar cells 4 are then graded and recycled at different levels. Corresponding grading measures are also taken for other module components of the module.

[0095] In summary, in the technical solution of this application, an elastic gasket 2 is provided between the front glass 1 and the rear glass 3. The sealing and encapsulation of the battery cell 4 is completed by the combined action of the elastic gasket 2, the encapsulating film 6, the front glass 1, and the rear glass 3. That is, the encapsulating film 6 can be omitted or used in a small amount at the position covering the elastic gasket 2. The elastic gasket 2 partially replaces the encapsulating film 6, thereby reducing the amount of encapsulating film 6 used. This not only reduces the material cost of the encapsulating film 6 and the weight of the solar photovoltaic module, but also reduces the separation cost of the encapsulating film 6 and the solar photovoltaic module, which is beneficial to the later maintenance and recycling of the solar photovoltaic module.

[0096] This application may also provide a solar photovoltaic module, including: a solar photovoltaic module;

[0097] The solar photovoltaic module is sealed and encapsulated within the solar photovoltaic module encapsulation device described above.

For example, if a device in the drawings is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein are interpreted accordingly.

[0099] It should also be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this application refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this application.

[0100] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0101] It should also be noted that the above are merely preferred embodiments of this application and do not limit the scope of patent protection of this application. Any equivalent structural or procedural changes made using the content of this application’s specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
