[0020] As the background technology indicates, the issue of adhesive overflow in photovoltaic (PV) module frames needs to be addressed. Specifically, during the installation of laminates in PV module frames, adhesive is typically applied using a glue applicator to fill the receiving grooves in the PV module frame. The laminate is then inserted into the receiving groove, where the adhesive secures the laminate and the module frame. However, during the insertion of the laminate into the receiving groove, some adhesive may overflow due to pressure from the laminate and spill onto parts of the laminate's surface outside the receiving groove. This affects the bonding quality between the module frame and the laminate, as well as the aesthetics of the PV module. Therefore, the PV module frame problem urgently needs to be solved.
[0021] This disclosure provides a photovoltaic module frame and a photovoltaic module. In the photovoltaic module frame, when the laminate is inserted into the receiving groove, the inclined first anti-overflow section can prevent the adhesive from overflowing outward and change the flow direction of part of the adhesive, so that the adhesive flowing away from the first side moves towards the first side, which helps to solve the adhesive overflow problem. In addition, the anti-overflow groove formed by the first anti-overflow section and the second anti-overflow section can accommodate the adhesive that overflows outward due to the compression of the laminate, preventing the adhesive from overflowing onto part of the surface of the laminate outside the receiving groove, which also helps to solve the adhesive overflow problem.
[0022] In addition, the insertion direction of the laminate is parallel to the first direction, and the extension direction of the second anti-overflow section is parallel to the first direction. When the second anti-overflow section contacts the laminate, the surface of the second anti-overflow section away from the first top edge can be parallel to the surface of the laminate. This helps to increase the contact area between the second anti-overflow section and the laminate, reduce the stress exerted by the second anti-overflow section on the laminate, and avoid damage to the laminate due to stress concentration, thereby improving the reliability of the photovoltaic module frame.
[0023] In the description of the embodiments of this disclosure, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary or secondary relationship of the indicated technical features.

However, those skilled in the art will understand that many technical details have been provided in the embodiments of this disclosure to facilitate a better understanding of the disclosure. However, the technical solutions claimed in this disclosure can be implemented even without these technical details and various variations and modifications based on the following embodiments.
[0032] Figure 1 This is a schematic diagram of a photovoltaic module frame provided in an embodiment of the present disclosure.
[0033] refer to Figure 1The photovoltaic module frame includes a frame body 1 and an anti-overflow structure 2. The frame body 1 includes a first top edge 11 and a second top edge 12 disposed opposite to each other, and a first side edge 13 connecting the first top edge 11 and the second top edge 12. The first top edge 11 extends along a first direction X. The anti-overflow structure 2 includes a first anti-overflow section 21 and a second anti-overflow section 22. The first anti-overflow section 21 is connected between the second anti-overflow section 22 and the first top edge 11. The first anti-overflow section 21 is inclined towards the second top edge 12 relative to the first top edge 11. The second anti-overflow section 22 extends from the end of the first top edge 11 away from the first side edge 13 toward the first side edge 13. The extension direction of the second anti-overflow section 22 is parallel to the first direction X. The first anti-overflow section 21 and the second anti-overflow section 22 form an anti-overflow groove 3. The anti-overflow structure 2, the first top edge 11, the first side edge 13, and the second top edge 12 form a receiving groove 4 for placing laminates.
[0034] The extension direction of the first top edge 11 can be parallel to the first direction X.
[0035] When the laminate is installed in the receiving tank 4, one surface of the laminate abuts against the second top edge 12, and the other surface of the laminate abuts against the second anti-overflow section 22. The extension direction of the second top edge 12 is parallel to the first direction, and the extension direction of the second anti-overflow section 22 is also parallel to the first direction X. That is, the second top edge 12 and the laminate are in surface contact, and the second anti-overflow section 22 and the laminate are also in surface contact. This helps to reduce the stress exerted on the laminate by the second top edge 12 and the second anti-overflow section 22, avoid damage to the laminate due to stress concentration, and thus improve the reliability of the photovoltaic module.
[0036] Figure 2 This is a schematic diagram of another structure of the photovoltaic module frame provided in an embodiment of this disclosure.
[0037] refer to Figure 2 In some embodiments, the second top edge 12 includes a recess 121 and a first main body 122. The recess 121 is recessed relative to the first main body 122 in a direction away from the first side edge, and the recess 121 is connected to the first side edge 13. The laminate may include a glass cover plate, which abuts against the second top edge 12. The edge of the laminate placed in the receiving groove 4 near the first side edge 12 is relatively fragile. If it comes into direct contact with the second top edge 12, which has a higher material hardness, there is a risk of the glass cover plate breaking under load. The presence of the recess 121 ensures that the necessary thickness of the colloid acts as a buffer medium, which can protect the glass cover plate of the laminate and improve the reliability of the photovoltaic module.
[0038] In some embodiments, the length of the recess 121 along the first direction X is 2mm to 5mm, for example, 2mm, 3mm, 4mm, or 5mm. The distance between the recess 121 and the first main body 122 along the second direction Y is 0.2mm to 1mm, that is, the depth of the recess 121 is 0.2mm to 1mm, for example, 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm. The length and depth of the recess 121 along the first direction X are within the above ranges, allowing it to accommodate a suitable amount of adhesive as a buffer medium for the laminate to contact the second top edge 12.
[0039] refer to Figure 1 or Figure 2 In some embodiments, the frame body 1 further includes a second side portion 14, a third side portion 15, a first bottom portion 16, and a second bottom portion 17 disposed opposite to each other. The second side portion 14 is partially fitted with the first side portion 13, and the third side portion 15 is connected to the second top portion 12; the first bottom portion 16 is connected to the second side portion 14, and the first bottom portion 16 is directly opposite the second top portion 12; the second bottom portion 17 is connected to the third side portion 15, and the second bottom portion 17 is located on a portion of the surface of the first bottom portion 16 facing the second top portion 12; wherein, the second top portion 12, the second side portion 14, the third side portion 15, and the portion of the first bottom portion 16 near the second side portion 14 form a cavity 5. The presence of the cavity 5 improves the bending and torsional strength of the photovoltaic module frame, thereby improving the performance of the photovoltaic module frame. The cavity 5 can also be used to accommodate external mating structures to fix the photovoltaic module frame.
[0040] The extension direction of the second side portion 14 is parallel to the second direction Y, and the extension direction of the second side portion 15 is also parallel to the second direction Y.
[0041] The first bottom edge 16 extends in a direction parallel to the first direction X, the first bottom edge 17 extends in a direction parallel to the first direction X, and the first top edge 11 extends in a direction parallel to the first direction X. Therefore, the first bottom edge 16 can be parallel to the first top edge 11. In this way, when multiple photovoltaic module frames are stacked vertically along the second direction Y, the first top edge 11 can be supported by the first bottom edge 16 in a surface contact manner, ensuring the contact effect and preventing slippage between the stacked photovoltaic module frames.
[0042] refer to Figure 1 or Figure 2In some embodiments, the frame body 1 further includes a first rolled edge portion 18 and a second rolled edge portion 19. The first rolled edge portion 18 is connected to the end of the second bottom edge portion 17 away from the third side edge portion 15, and the first rolled edge portion 18 bends from the second bottom edge portion 17 away from the first bottom edge portion 16 and extends toward the third side edge portion 15. The ends of the first rolled edge portion 18 and the second bottom edge portion 17 form a snap-fit groove (not shown). The second rolled edge portion 19 is connected to the end of the first bottom edge portion 16 away from the second side edge portion 14. The second rolled edge portion 19 is located on the outer surface of the first rolled edge portion 18, and the end of the second rolled edge portion 19 away from the second side edge portion 14 snaps into the snap-fit groove. The first rolled edge portion 18 and the second rolled edge portion 19 are connected in this way, which has a strong fixing effect and can improve the stability of the component frame.
[0043] In some embodiments, the third side portion 15 further includes a second main body portion 151 and at least one reinforcing rib 152, the reinforcing rib 152 being recessed relative to the second main body portion 151 toward the second side portion 14. The reinforcing rib 152 can improve the mechanical strength of the photovoltaic module frame, thereby more effectively bearing external loads.
[0044] The number of reinforcing ribs 152 can be 1, 2, or 3, etc.
[0045] In some embodiments, the length of the reinforcing rib 152 along the second direction Y is 5mm to 20mm, for example 5mm, 7mm, 9mm, 11mm, 13mm, 15mm, 17mm, 18mm or 20mm, and the distance between the reinforcing rib 152 and the second main body portion 151 along the first direction X is 0.5mm to 2mm, for example 0.5mm, 0.8mm, 1mm, 1.2mm, 1.4mm, 1.6mm, 1.8mm or 2mm.
[0046] refer to Figure 1 or Figure 2 In some embodiments, the first anti-overflow section 21 extends along a third direction Z, and the length of the first anti-overflow section 21 along the third direction Z is 3mm to 8mm, for example, 3mm, 4mm, 5mm, 6mm, 7mm or 8mm. The length of the first anti-overflow section 21 is within the above range, which can avoid the bending of the processing process due to the first anti-overflow section 21 being too short, and can also avoid the cost of the photovoltaic module frame being increased due to the first anti-overflow section 21 being too long.
[0047] The angle between the third direction Z and the first direction X is greater than 0° and less than 90°. Specifically, the angle between the third direction Z and the first direction X can be 1°, 5°, 10°, 15°, 25°, 30°, 40°, 50°, 60°, 70°, 80°, 85° or 89°.
[0048] In some embodiments, the length of the second anti-overflow section 22 along the first direction X is 2mm to 6mm, for example, 2mm, 3mm, 4mm, 5mm or 6mm. The length of the second anti-overflow section 22 is within the above range, which can prevent excessive stress concentration on the laminate during contact due to an excessively short second anti-overflow section 22, thus avoiding damage to the laminate. It can also prevent an excessively long second anti-overflow section 22 from increasing the cost of the photovoltaic module frame.
[0049] In the aforementioned photovoltaic module frame, when the laminate is inserted into the receiving groove 4, the inclined first anti-overflow section 21 can prevent the adhesive from overflowing outwards and change the flow direction of some of the adhesive, causing the adhesive flowing away from the first side 13 to flow towards the first side 13 again, which helps to solve the adhesive overflow problem. Furthermore, the anti-overflow groove 3 formed by the first anti-overflow section 21 and the second anti-overflow section 22 can accommodate the adhesive that overflows outwards due to the compression of the laminate, preventing the adhesive from overflowing onto part of the surface of the laminate outside the receiving groove 4, which also helps to solve the adhesive overflow problem.
[0050] In addition, the insertion direction of the laminate is parallel to the first direction X, and the extension direction of the second anti-overflow section 22 is parallel to the first direction X. When the second anti-overflow section 22 contacts the laminate, the surface of the second anti-overflow section 22 away from the first top edge 11 can be parallel to the surface of the laminate. This helps to increase the contact area between the second anti-overflow section 22 and the laminate, reduce the stress exerted by the second anti-overflow section 22 on the laminate, and avoid damage to the laminate due to stress concentration, thereby improving the reliability of the photovoltaic module frame.
[0051] This disclosure also provides a photovoltaic module, which includes a photovoltaic module frame as provided in any of the foregoing embodiments. The photovoltaic module is used to convert received light energy into electrical energy. It should be noted that the parts that are the same as or corresponding to those in the foregoing embodiments can be referred to the corresponding descriptions in the foregoing embodiments, and will not be repeated below.
[0052] Figure 3 This is a schematic diagram of a laminate provided in an embodiment of the present disclosure.
[0053] Reference Figure 1 and Figure 3 The photovoltaic module also includes a laminate 6, which is installed in the receiving groove 4 of the photovoltaic module frame.
[0054] The laminate 6 includes a battery string formed by connecting multiple battery cells 61, an encapsulating film 62, and a cover plate 63. The encapsulating film 62 is used to cover the surface of the battery string; the cover plate 63 is used to cover the surface of the encapsulating film that is away from the battery string.
[0055] The solar cell 61 includes, but is not limited to, one or any combination of PERC (Passivated Emitter Rear Cell), IBC (Interdigitated Back Contact), TOPCON (Tunnel Oxide Passivated Contact), HIT / HJT (Heterojunction Technology), thin-film solar cells, and tandem solar cells. Figure 3 Taking TOPCON batteries as an example.
[0056] Adjacent solar cells 61 can be electrically connected via solder strips 64.
[0057] In some embodiments, the encapsulating film 62 includes a first encapsulating layer and a second encapsulating layer. The first encapsulating layer covers one of the front and back sides of the back contact cell 30, and the second encapsulating layer covers the other of the front and back sides of the solar cell. Specifically, at least one of the first and second encapsulating layers can be an organic encapsulating film such as polyvinyl butyral (PVB) film, ethylene-vinyl acetate copolymer (EVA) film, polyvinyl octene coelastomer (POE) film, or polyethylene terephthalate (PET) film. Alternatively, at least one of the first and second encapsulating layers can also be an EP film, EPE film, or PVP film.
[0058] Among them, EP film refers to a co-extruded film composed of stacked EVA film and POE film; EPE film refers to a co-extruded film formed by sequentially stacking EVA film, POE film, and EVA film; and PVP film refers to a co-extruded film formed by stacking POE film, EVA film, and POE film. Co-extruded films can be manufactured by sequentially extruding one or more raw materials onto another pre-made film during the film processing, or by bonding different types of pre-made films together.
[0059] In some cases, there is a boundary between the first encapsulation layer and the second encapsulation layer before lamination. After the photovoltaic module is formed by lamination, there is no longer a concept of a first encapsulation layer and a second encapsulation layer. That is, the first encapsulation layer and the second encapsulation layer have formed an integral encapsulation film.
[0060] In some embodiments, the cover plate 63 can be a glass cover plate, a plastic cover plate, or other cover plate with light-transmitting function. Specifically, the surface of the cover plate facing the encapsulating film can be an uneven surface or a textured surface containing multiple raised structures, thereby increasing the utilization rate of incident light. The cover plate 63 includes a first cover plate and a second cover plate, the first cover plate being opposite to the first encapsulation layer, and the second cover plate being opposite to the second encapsulation layer.
[0061] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes in form and detail may be made without departing from the spirit and scope of this disclosure. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this disclosure; therefore, the scope of protection of this disclosure should be determined by the scope defined in the claims.
