Description

Technical Field

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

[0002] Compared to PERC modules, TOPCon, HJT, and xBC cells offer higher cell efficiency and higher module power output, effectively reducing the cost per kilowatt-hour and increasing the profitability of photovoltaic modules. However, due to structural design and paste selection, these new cells have stricter requirements for the operating environment, especially for moisture isolation. If moisture enters, the new cells will corrode, leading to power degradation.

[0003] Currently, photovoltaic modules made using new photovoltaic cell technology typically use double-sided glass to prevent moisture intrusion. However, double-sided glass modules are heavier than single-sided glass modules, making them less suitable for use on roofs with low load-bearing capacity.

[0004] However, single-glass modules often neglect the water-blocking design at the openings where the leads on the back of the photovoltaic module emerge, and the problem of water vapor intrusion in new single-glass battery modules urgently needs to be solved.

[0005] 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

[0006] This application provides a photovoltaic laminate and a photovoltaic module to solve or alleviate one or more of the technical problems mentioned above.

[0007] As a first aspect of the embodiments of this application, the embodiments of this application provide a photovoltaic laminate.

[0008] According to an embodiment of this application, the photovoltaic laminate includes encapsulation glass, a first encapsulation material layer, a cell string, a second encapsulation material layer, and a backsheet, which are stacked sequentially.

[0009] The back plate is provided with lead wire openings, and the battery string is provided with busbars. The busbars are led out from the lead wire openings after passing through the second encapsulation material layer.

[0010] A water-blocking mechanism is provided between the lead wire opening and the second encapsulation material layer.

[0011] In the embodiments of this application, a water-blocking mechanism is introduced between the lead wire opening on the back sheet and the second encapsulation material layer in the photovoltaic laminate. When water vapor enters through the lead wire opening, the presence of the water-blocking mechanism can prevent water vapor from diffusing into the second encapsulation material layer or even the battery string, thereby avoiding water vapor entering the interior of the photovoltaic module and causing adverse effects.

[0012] Optionally, in this photovoltaic laminate, the water-blocking mechanism is a water-blocking sheet with two channels. Thus, the presence of this water-blocking sheet prevents moisture entering through the lead wire openings from contacting the second encapsulation material layer.

[0013] Optionally, in this photovoltaic laminate, the water-blocking mechanism includes: a water-blocking sheet and an adhesive layer stacked together; two channels that penetrate the water-blocking sheet and the adhesive layer; wherein the adhesive layer is disposed on the side closest to the lead wire opening. Thus, the water-blocking mechanism can be bonded to the lead wire opening on the backsheet of the photovoltaic module using a film-applying device. Simultaneously, it allows for more accurate positioning of the water-blocking mechanism.

[0014] Optionally, in this photovoltaic laminate, the water-blocking mechanism includes: a water-blocking sheet and a frustum stacked together; two channels that are disposed through the water-blocking sheet and the frustum; wherein the frustum is disposed within the lead wire opening. Thus, water-blocking material is also provided within the lead wire opening, preventing the lead wire opening from acting as a water vapor channel.

[0015] Optionally, in this photovoltaic laminate, the water-blocking mechanism includes an air-side water-blocking plug and an encapsulation-side water-blocking plug. Both the air-side and encapsulation-side water-blocking plugs employ a top-plug structure. Each plug includes a main body structure and a top portion on the main body structure, with the two main bodies nested together. A channel is provided inside the integrated air-side and encapsulation-side water-blocking plugs. The air-side water-blocking plug is located on the side of the lead-out opening furthest from the second encapsulation material layer, while the encapsulation-side water-blocking plug is located on the side of the lead-out opening closest to the second encapsulation material layer. Thus, the water-blocking plug design achieves complete sealing of the lead-out opening. Water-blocking material is provided inside the lead-out opening and at both ends of the lead-out opening, completely preventing water vapor from entering the laminate through the lead-out opening.

[0016] As a second aspect of the present application, the present application provides a photovoltaic module.

[0017] This photovoltaic module includes the photovoltaic laminate described in the first aspect. Therefore, it has excellent moisture isolation capabilities. Attached Figure Description

The application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0031] This application addresses the need for sufficient water resistance in single-glass photovoltaic modules based on battery technology. It incorporates a water-resistant design with perforated leads on the back of the photovoltaic module, utilizing mainstream backsheets and high water-resistant aluminum foil backsheets. This design comprehensively protects the internal photovoltaic cells and meets the module's requirements for moisture barrier.

[0032] This application provides a photovoltaic laminate and a photovoltaic module. Based on this, the problem of corrosion caused by moisture intrusion is solved. See below for details.

[0033] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0034] In some embodiments, such as Figures 1-3 As shown, the photovoltaic laminate includes an encapsulation glass 1, a first encapsulation material layer 2, a battery string 3, a second encapsulation material layer 4, and a backplate 5, which are stacked in sequence.

[0035] The backplate 5 is provided with lead wire openings, and the battery string 3 is provided with busbars 8. The busbars 8 are led out through the lead wire openings after passing through the second encapsulation material layer 4.

[0036] A water-blocking mechanism 6 is provided between the lead wire opening and the second encapsulation material layer 4.

[0037] In the embodiments of this application, a water-blocking mechanism 6 is introduced between the lead wire opening of the back sheet 5 and the second encapsulation material layer 4 in the photovoltaic laminate. When water vapor enters through the lead wire opening, the presence of the water-blocking mechanism 6 can prevent water vapor from diffusing into the second encapsulation material layer 4 or even the battery string, thereby avoiding water vapor entering the interior of the photovoltaic module and causing adverse effects.

[0038] It is worth noting that the battery string 3 refers to the formation of multiple battery cells connected in series by interconnecting strips 7. Interconnecting strips 7 of different polarities are led out through two busbars 8, and the busbars 8 are finally led out through the lead wire openings on the back plate 5.

[0039] This application does not limit the encapsulation glass 1, the first encapsulation material layer 2, the second encapsulation material layer 4, and the backplate 5; those skilled in the art can choose according to their needs. For example, the encapsulation glass 1 can be 3.2mm fully tempered glass; the first encapsulation material layer 2 and the second encapsulation material layer 4 can be independently made of ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), or EPE encapsulation film made by co-extrusion of two layers of EVA resin and one layer of POE resin; the backplate 5 can be a backplate with a Coating+PET+Coating (CPC) structure, a PVDF+PET+Coating (KPC) structure, or a PET+Coating (PC) structure. Wherein, PVDF is polyvinylidene fluoride; PET is polyethylene terephthalate; and Coating is a coating.

[0040] In some embodiments, the cells in the battery string 3 can be at least one of TOPCon, HJT, xBC, etc. This provides the battery assembly with good moisture isolation, resulting in stable power output.

[0041] In some embodiments, see Figure 1 As shown in Figure 4, in this photovoltaic laminate, the water-blocking mechanism 6 is a water-blocking sheet 601, which has two channels 603. Therefore, the presence of the water-blocking sheet 601 prevents moisture entering through the lead wire openings from contacting the second encapsulation material layer 4.

[0042] Furthermore, the water-blocking sheet 601 is made of at least one of butyl rubber, graphene, and sheet-like sericite. Therefore, the water-blocking sheet 601 has excellent moisture barrier capabilities.

[0043] Furthermore, the thickness of the water-blocking sheet 601 is 0.5mm to 1.5mm. This ensures moisture isolation while preventing unevenness on the back surface caused by excessive thickness.

[0044] Furthermore, channel 603 is used to accommodate busbar 8, and the size of channel 603 can be determined by the size of busbar 8. For example, when the size of busbar 8 is 0.25mm×4mm to 0.25mm×7mm, the width of channel 603 can be 0.5mm to 1mm, and the length of channel 603 can be 5mm to 10mm.

[0045] In other embodiments, see Figure 1 As shown in Figure 5, in this photovoltaic laminate, the water-blocking mechanism 6 includes: a water-blocking sheet 601 and an adhesive layer 602 stacked together; two channels 603 extending through the water-blocking sheet 601 and the adhesive layer 602; wherein the adhesive layer 602 is positioned near the lead wire opening. Therefore, the water-blocking mechanism 6 can be bonded to the lead wire opening on the backsheet of the photovoltaic module using a film-applying device. This also makes the bonding and fixing position of the water-blocking mechanism 6 more accurate.

[0046] Furthermore, the water-blocking sheet 601 is made of at least one of butyl rubber, graphene, and sheet-like sericite. Therefore, the water-blocking sheet 601 has excellent moisture barrier capabilities.

[0047] Furthermore, the thickness of the water-blocking sheet 601 is 0.5mm to 1.5mm. This ensures moisture isolation while preventing unevenness on the back surface caused by excessive thickness.

[0048] Furthermore, the dimensions of channel 603 can be determined by the dimensions of busbar 8. For example, when the dimensions of busbar 8 are 0.25mm×4mm to 0.25mm×7mm, the width of channel 603 can be 0.5mm to 1mm, and the length of channel 603 can be 5mm to 10mm.

[0049] Furthermore, the adhesive layer 602 includes at least one of acrylic pressure-sensitive adhesive, TPO hot melt adhesive (hot melt adhesive for thermoplastic polyolefins), and epoxy resin adhesive. Therefore, the water-blocking mechanism can be bonded to the lead-out openings on the backsheet of the photovoltaic module using a film-applying device, resulting in more accurate positioning of the water-blocking mechanism.

[0050] Furthermore, the thickness of the adhesive layer 602 includes 0.05mm to 0.08mm. This ensures that the adhesive layer has good bonding ability and does not generate stress during lamination due to excessive thickness.

[0051] In some other embodiments, see Figure 2 As shown in Figure 6, in this photovoltaic laminate, the water-blocking mechanism 6 includes: a water-blocking sheet 601 and a frustum stacked together, with two channels formed in the water-blocking sheet 601 and the frustum; and two channels 603 extending through the water-blocking sheet 601 and the frustum; wherein the frustum is disposed within the lead wire opening. Thus, water-blocking material is also provided within the lead wire opening, preventing the lead wire opening from acting as a water vapor channel.

[0052] Furthermore, an adhesive layer 602 is provided on the side of the water-blocking sheet 601 near the truncated cone, thereby serving to bond and fix it.

[0053] Furthermore, the material of the water-blocking sheet 601 includes at least one of butyl rubber, graphene, and sheet sericite.

[0054] Furthermore, the thickness of the water-blocking sheet 601 is 0.5mm to 1.5mm.

[0055] Furthermore, the adhesive layer 602 includes at least one of acrylic pressure-sensitive adhesive, TPO hot melt adhesive, and epoxy resin adhesive.

[0056] Furthermore, the thickness of the adhesive layer 602 includes 0.05mm to 0.08mm.

[0057] Furthermore, the aperture of the channel 603 is 0.5mm to 1mm.

[0058] Furthermore, the height of the frustum can be less than or equal to the thickness of the back plate 5. For example, when the thickness of the back plate 5 is 0.3mm to 0.5mm, the height of the frustum can be 0.3mm to 0.5mm.

[0059] In some other embodiments, see Figure 3 and Figure 7In this photovoltaic laminate, the water-blocking mechanism 6 includes an air-side water-blocking plug 605 and an encapsulation-side water-blocking plug 604. Both the air-side water-blocking plug 605 and the encapsulation-side water-blocking plug 604 employ a top-plug structure. Each includes a main structure and a top portion on the main structure, with the two main structures nested together. A channel 603 is provided inside the integrated air-side water-blocking plug 605 and encapsulation-side water-blocking plug 604. The air-side water-blocking plug 605 is located on the side of the lead-out opening away from the second encapsulation material layer 4, while the encapsulation-side water-blocking plug 604 is located on the side of the lead-out opening closer to the second encapsulation material layer 4. Thus, the water-blocking plug design achieves complete sealing of the lead-out opening. Water-blocking material is provided inside the lead-out opening and at both ends of the lead-out opening, completely preventing water vapor from entering the laminate through the lead-out opening.

[0060] Furthermore, the main structure of the air-side water-blocking plug 605 is nested within the main structure of the encapsulation-side water-blocking plug 604, and the main structures of the two together form a nested main body 606.

[0061] Furthermore, the material of the water-blocking plug can be at least one of butyl rubber, ABS resin, silicone rubber, nano-silica, etc. These materials have good water-blocking properties, are easy to mold, and offer high performance and manufacturing advantages.

[0062] Furthermore, the top diameter of the air-surface water-blocking plug 605 can be designed according to the busbar opening size, and should be larger than the conventional opening diameter, but should not exceed the coverage area of ​​the external junction box to avoid leakage of the water-blocking plug. For example, the top diameter of the air-surface water-blocking plug 605 can be 15mm to 35mm. The top thickness of the air-surface water-blocking plug 605 depends on the water-blocking performance requirements to prevent excessive protrusion from affecting the bonding and fixing of the junction box. For example, the top thickness of the air-surface water-blocking plug 605 can be 0.25mm to 0.5mm.

[0063] Furthermore, the top diameter of the water-blocking plug 604 on the encapsulation surface can be 15mm to 35mm, and the top thickness can be 0.01mm to 0.10mm. The water-blocking plug is designed according to the busbar opening size and needs to be larger than the conventional opening diameter; however, excessive overlap between the water-blocking plug and the battery cell should be avoided to prevent cell compression. Its thickness depends on the water-blocking performance requirements; a top thickness of 0.01mm to 0.10mm prevents excessive protrusion that could compress the second encapsulation material layer during lamination.

[0064] Furthermore, the diameter of the channel 603 in the middle of the water-blocking plug can be 8mm to 16mm. This diameter can be designed according to the size of the lead wire opening, and in principle should be less than 60% of the diameter of the lead wire opening, so as to leave space for the water-blocking plug to be inserted.

[0065] Furthermore, the diameter difference between the outer wall of the air-surface water-blocking plug 605 and the inner wall of the encapsulation layer water-blocking plug is less than 1mm, which can be filled and sealed with photovoltaic module potting compound to form a sealed channel and block water vapor without affecting installation.

[0066] In some embodiments, the laminate is according to Figure 3 After completing the laying of all components except the backplate 5, the encapsulation surface water-blocking plug is placed on the second encapsulation material layer 4, and the main structure of the encapsulation surface water-blocking plug is inserted into the lead wire opening. Then, the main structure of the air surface water-blocking plug is inserted into the encapsulation surface water-blocking plug through laser alignment or physical alignment to form a closed water-blocking plug. Then, the manifold 8 is inserted into the through hole of the water-blocking plug to complete the laying. After lamination, the second encapsulation material layer 4 is heat-deformed to obtain... Figure 3 The laminate shown.

[0067] A second aspect of this application provides a photovoltaic module, including the photovoltaic laminate described in the first aspect. Optionally, the busbar 8 can be encapsulated in a junction box, and the two sides of the photovoltaic laminate can be assembled using frames to obtain the photovoltaic module. This provides excellent moisture isolation capability.
