[0008] According to one embodiment of this application, the first substrate has an opening, the support component has a through hole, the opening corresponds to the through hole, and the first adhesive film, the first substrate, the support component and the second substrate are thermally fused together as one unit.

[0009] According to the photovoltaic module of this application, by setting openings and through holes, the first adhesive film that melts during hot pressing flows into the support component, bonding the first substrate, the support component and the second substrate together, and then bonding the front panel and the reinforcing component together, the integration is good, thereby enhancing the structural strength of the photovoltaic module and the photovoltaic module has high impact resistance and load capacity.

[0010] According to one embodiment of this application, the support assembly includes an upper part and a lower part, and the outer wall of the lower part is provided with pores spaced apart circumferentially.

[0011] According to the photovoltaic module of this application, by providing vents at the bottom of the support component, the hot-melt first adhesive film can flow smoothly into the support component with less resistance, thus preventing the hot-melt first adhesive film from condensing before flowing into the support component.

[0012] According to one embodiment of this application, the support component is provided with a connecting portion, and the first adhesive film flowing into the through hole is connected to the connecting portion.

[0013] According to the photovoltaic module of this application, by providing a connecting part in the support component, the connection stability between the first encapsulant film and the support component is improved, and the condensation efficiency of the first encapsulant film is also improved.

[0014] According to one embodiment of this application, the support component includes an upper part and a lower part, the upper part abutting against the first substrate at one end away from the lower part, the cross-sectional area of ​​the upper part gradually decreasing in the direction away from the front plate, and the lower part being sandwiched between the upper part and the second substrate.

[0015] According to the photovoltaic module of this application, by setting the structure of the support module and the tilt direction of the upper part, the fluidity of the first encapsulant film is improved, and the first encapsulant film has a better filling effect on the support module.

[0016] According to one embodiment of this application, the upper part has a trapezoidal cross-section along the stacking direction of the photovoltaic module, and the lower part has a rectangular cross-section along the stacking direction of the photovoltaic module.

[0017] According to the photovoltaic module of this application, by setting an upper and lower structure, the overall structural strength of the photovoltaic module can be improved while ensuring the fluidity of the hot-melt first adhesive film.

[0018] According to one embodiment of this application, the first substrate, the second substrate, and the support assembly are integrally injection molded.

[0019] The photovoltaic module according to this application adopts an integrated injection molding process for the first substrate, the second substrate and the supporting components, which has high production efficiency, low cost, avoids assembly errors, ensures the structural strength of the photovoltaic module and has a long service life.

[0020] According to one embodiment of this application, the front panel, first adhesive film, reinforcing component, second adhesive film, battery, and back panel stacked sequentially are connected by heat fusion of corresponding adhesive films between each adjacent pair.

[0021] According to the photovoltaic module of this application, by thermally fusing each adjacent pair of the front panel, first encapsulant film, reinforcing component, second encapsulant film, cell and back panel stacked in sequence, adjacent components are bonded together while also providing a buffering effect. The photovoltaic module has high structural strength and good integration.

[0022] According to one embodiment of this application, the reinforcing component has a plurality of the support components, which are spaced apart between the first substrate and the second substrate.

[0023] According to the photovoltaic module of this application, by setting multiple support components spaced apart between the first substrate and the second substrate, the structural strength of the photovoltaic module is ensured while the number of support components is reasonably set, thereby reducing costs and improving economic efficiency.

[0046] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0047] The principle of the photovoltaic module 1 proposed in this application will be explained in detail below:

[0048] In related technologies, with the rapid development of the photovoltaic industry, the types and application scenarios of photovoltaic modules are constantly expanding. Photovoltaic modules are used in balconies, roofs and some portable scenarios (such as automobiles). In order to meet the load capacity requirements of the above scenarios, photovoltaic modules often use flexible materials such as transparent polymer materials to replace traditional glass materials, achieving a significant reduction in weight. However, this leads to a decrease in the impact resistance of photovoltaic modules, posing a risk of damage during use.

[0049] To address this technical problem, this application provides a photovoltaic module 1, which is described below with reference to... Figures 1-5 A photovoltaic module 1 according to an embodiment of this application is described.

[0050] like Figure 3 As shown, the photovoltaic module 1 of this application embodiment includes: a front panel 10, a first encapsulant film 20, a reinforcing component 30, a second encapsulant film 40, a cell 50, and a back panel 70.

[0051] In this embodiment, a third adhesive film 60 is also included, and the front panel 10, the first adhesive film 20, the reinforcing component 30, the second adhesive film 40, the battery 50, the third adhesive film 60 and the back panel 70 are stacked in sequence.

[0052] In some embodiments, the third adhesive film 60 may not be included, and the front panel 10, the first adhesive film 20, the reinforcing component 30, the second adhesive film 40, the battery 50, and the back panel 70 may be stacked in sequence.

[0053] The front panel 10 can be made of fluorine-containing transparent PET (polyethylene terephthalate), ETFE (ethylene-tetrafluoroethylene copolymer), PVF (polyvinylidene fluoride), or PVDF (polyvinylidene difluoride).

[0054] The first adhesive film 20, the second adhesive film 40, and the third adhesive film 60 can be made of materials such as EVA (ethylene-vinyl acetate copolymer), POE (ethylene-octene copolymer), EPE (extruded polyolefin elastomer), or PVB (polyvinyl butyral). The materials of the first adhesive film 20, the second adhesive film 40, and the third adhesive film 60 can be the same or different.

[0055] In this embodiment, the first adhesive film 20, the second adhesive film 40 and the third adhesive film 60 can be made of PVB material. After hot pressing and curing, the hardness of the adhesive film is significantly improved, which can further enhance the structural strength of the photovoltaic module 1.

[0056] It should be noted that the first adhesive film 20, the second adhesive film 40, and the third adhesive film 60 can be single-layer adhesive films or multi-layer adhesive films.

[0057] The first adhesive film 20, the second adhesive film 40, and the third adhesive film 60 can provide adhesion to adjacent components and act as a buffer layer.

[0058] like Figure 4 As shown, the reinforcing component 30 includes: a first substrate 31, a second substrate 32, and a support component 33.

[0059] The first substrate 31 and the second substrate 32 are flat plates. The first substrate 31 and the second substrate 32 can ensure the structural strength of the reinforcing component 30 and can withstand the impact force from top to bottom. At the same time, the flat plate structure can buffer the local impact force. The flat plate structure has a large area, which reduces the pressure of the impact force transmitted to the battery 50.

[0060] The support component 33 is clamped between the first substrate 31 and the second substrate 32.

[0061] In this embodiment, the two ends of the support component 33 are respectively connected to the first substrate 31 and the second substrate 32 to form a three-layer reinforced structure. The cross-sectional area of ​​the upper and lower layers is larger than that of the middle layer. While ensuring the photovoltaic module 1's resistance to frontal impact, it provides greater support force and improves the load performance of the photovoltaic module 1.

[0062] In related technologies, with the rapid development of the photovoltaic industry, the types and application scenarios of photovoltaic modules are constantly expanding. Photovoltaic modules are used in balconies, roofs, and some portable scenarios (such as automobiles). To meet the load-bearing capacity requirements of these scenarios, photovoltaic modules often use flexible materials such as transparent polymer materials to replace traditional glass materials, achieving a significant reduction in weight. However, this also leads to a decrease in the impact resistance of photovoltaic modules, posing a risk of damage during use. Existing technologies improve impact resistance by increasing the thickness of the front material or filling it with glass fiber. Since the front material is a soft material, increasing the thickness of the front material results in a significant increase in cost with limited improvement in impact resistance. When using glass fiber filling, the glass fiber needs to be used in conjunction with a reinforcing agent. The reinforcing agent has relatively unstable chemical properties, high cost, and poor performance.

[0063] In this embodiment, the photovoltaic module 1 employs a structure where a support component 33 is sandwiched between a first substrate 31 and a second substrate 32 to form a reinforcing component 30. The photovoltaic module 1 is stacked sequentially in the following order: front panel 10, first encapsulant film 20, reinforcing component 30, second encapsulant film 40, cell 50, third encapsulant film 60, and back panel 70. After stacking, hot pressing is performed to melt the first encapsulant film 20, second encapsulant film 40, and third encapsulant film 60, thus bonding the front panel 10, reinforcing component 30, cell 50, and back panel 70. The three-layer reinforcing component 30, together with the first encapsulant film 20 and second encapsulant film 40 on both sides, plays a buffering and pressure-resistant role. The larger area of ​​the first substrate 31 and second substrate 32 can withstand the pressure. The impact force on the surface is dispersed and the pressure is small, so it will not damage the battery 50. At the same time, the support component 33 sandwiched between the first substrate 31 and the second substrate 32 improves the structural strength and the load-bearing capacity of the photovoltaic module 1. The support component 33 can transmit the force on the first substrate 31 to the second substrate 32, with a good guiding effect. The first film 20, the second film 40 and the third film 60 constitute a multi-layer film structure. The flexible material also plays a certain role in buffering the impact force, realizing the structural strengthening effect of the photovoltaic module 1, improving the impact resistance and load-bearing capacity of the photovoltaic module 1. At the same time, the use of rigid structure in combination with flexible material reduces the amount of flexible material used, thus reducing the cost.

[0064] According to the photovoltaic module 1 provided in the embodiments of this application, the photovoltaic module 1 achieves a structural strengthening effect by setting a three-layer reinforcing component 30 and the internal stacking order of the photovoltaic module 1. The photovoltaic module 1 has high impact resistance and load capacity, low cost, good stability in use, and long life.

[0065] In some embodiments, such as Figure 5 As shown, the first substrate 31 may have an opening 311, and the support component 33 may have a through hole 331.

[0066] The opening 311 of the first substrate 31 can be circular, rectangular or other shapes. In this embodiment, the opening 311 of the first substrate 31 can be circular. The circular opening 311 can better guide the flow of hot melt adhesive film, reduce resistance and avoid local stress concentration.

[0067] like Figure 5 As shown, opening 311 corresponds to through hole 331.

[0068] The first adhesive film 20, the first substrate 31, the support component 33, and the second substrate 32 are thermally fused together as one unit.

[0069] In this embodiment, the photovoltaic module 1 is stacked sequentially in the order of front panel 10, first adhesive film 20, reinforcing component 30, second adhesive film 40, battery 50, third adhesive film 60, and back panel 70. A support component 33 is sandwiched between the first substrate 31 and the second substrate 32. The opening 311 of the first substrate 31 corresponds to the through hole 331 of the support component 33. After stacking, hot pressing is performed. A portion of the hot-melted first adhesive film 20 is bonded to the first substrate 31 and the front panel 10, and the other portion of the hot-melted first adhesive film 20 flows into the through hole 331 of the support component 33 through the opening 311 and fills the through hole 331 of the support component 33. The rigid structure combined with the flexible material achieves the structural reinforcement effect of the photovoltaic module 1. The photovoltaic module 1 has high impact resistance and load capacity. The first substrate 31, the support component 33, and the second substrate 32 are bonded together, and the front panel 10 and the reinforcing component 30 are bonded together, resulting in good integrity.

[0070] For example, the first substrate 31 and the second substrate 32 are flat plates. When the hot-melted first adhesive film 20 flows into the through hole 331 of the support component 33 through the opening 311, the second substrate 32 can achieve self-leveling of the first adhesive film 20, with good filling effect and uniform stress, which has a good effect on improving the impact resistance and load capacity of the photovoltaic module 1.

[0071] According to the photovoltaic module 1 provided in the embodiments of this application, by providing an opening 311 and a through hole 331, the first adhesive film 20 that melts during hot pressing flows into the support component 33, bonding the first substrate 31, the support component 33 and the second substrate 32 into one, and then bonding the front plate 10 and the reinforcing component 30 into one, the integration is good, thereby enhancing the structural strength of the photovoltaic module 1, and the photovoltaic module 1 has high impact resistance and load capacity.

[0072] In some embodiments, such as Figure 5 As shown, the support component 33 may include an upper part 332 and a lower part 333.

[0073] like Figure 5 As shown, the lower part 333 has pores 3331 spaced around its outer wall in the circumferential direction.

[0074] In this embodiment, the cross-section of the vent 3331 is rectangular. The vent 3331 is evenly spaced along the circumference of the outer wall of the lower part 333. When the hot-melted first adhesive film 20 flows into the through hole 331 of the support component 33 through the opening 311, the vent 3331 achieves internal and external air pressure balance, so that the hot-melted first adhesive film 20 can flow in smoothly with less resistance and faster flow rate, thus avoiding the condensation of the hot-melted first adhesive film 20 before it flows into the support component 33.

[0075] Understandably, the shape, size, and number of pores 3331 can be set according to actual usage requirements.

[0076] According to the photovoltaic module 1 provided in the embodiments of this application, by providing vents 3331 in the lower part 333 of the support component 33, the hot-melt first adhesive film 20 can flow smoothly into the support component 33 with less resistance, thus avoiding the condensation of the hot-melt first adhesive film 20 before it flows into the support component 33.

[0077] In some embodiments, such as Figure 5 As shown, the support component 33 may be provided with a connecting part 334.

[0078] The connecting part 334 can be a protrusion, a groove or other shape. The connecting part 334 is used for the first adhesive film 20 to flow into the support assembly 33 and then condense and connect.

[0079] The first adhesive film 20 flowing into the through hole 331 is connected to the connecting part 334.

[0080] In this embodiment, the connecting portion 334 is a groove, and the connecting portion 334 is located at the upper part 332 near the first substrate 31. When the hot-melted first adhesive film 20 flows into the support assembly 33, the groove-shaped connecting portion 334 has less resistance, avoiding affecting the smooth flow of the hot-melted first adhesive film 20 into the support assembly 33. When the hot-melted first adhesive film 20 condenses, the first adhesive film 20 can be embedded into the groove-shaped connecting portion 334 and fill the groove of the connecting portion 334. The connecting portion 334 increases the effective contact area between the first adhesive film 20 and the support assembly 33, and the heat dissipation is faster during the condensation stage. Compared with a flat surface, the groove-shaped connecting portion 334 has a better connection effect. After the first adhesive film 20 condenses, it forms an anchoring structure with the connecting portion 334, and the connection is more stable.

[0081] According to the photovoltaic module 1 provided in the embodiments of this application, by providing a connecting part 334 in the support component 33, the connection stability between the first encapsulant 20 and the support component 33 is improved, and the condensation efficiency of the first encapsulant 20 is also improved.

[0082] In some embodiments, such as Figure 5 As shown, the support component 33 may include an upper part 332 and a lower part 333.

[0083] The end of the upper part 332 that is away from the lower part 333 abuts against the first substrate 31.

[0084] like Figures 3-5 As shown, the cross-sectional area of ​​the upper part 332 gradually decreases in the direction away from the front plate 10, and the lower part 333 is sandwiched between the upper part 332 and the second substrate 32.

[0085] In this embodiment, the support component 33 is sandwiched between the first substrate 31 and the second substrate 32. The upper part 332 abuts against the first substrate 31, and the lower part 333 abuts against the second substrate 32. The cross-sectional area of ​​the upper part 332 gradually decreases in the direction away from the front plate 10, so that the outer wall of the upper part 332 is inclined outward in the direction away from the lower part 333, so that the hot-melted first adhesive film 20 can flow more fully and faster under the action of gravity, and the first adhesive film 20 has a better filling effect on the support component 33.

[0086] According to the photovoltaic module 1 provided in the embodiments of this application, by setting the structure of the support component 33 and the tilting direction of the upper part 332, the fluidity of the first adhesive film 20 is improved, and the first adhesive film 20 has a better filling effect on the support component 33.

[0087] In some embodiments, such as Figures 3-5 As shown, the cross-section of the upper part 332 along the stacking direction of the photovoltaic module 1 can be trapezoidal, and the cross-section of the lower part 333 along the stacking direction of the photovoltaic module 1 can be rectangular.

[0088] In this embodiment, the cross-section of the upper part 332 along the stacking direction of the photovoltaic module 1 is trapezoidal, making the upper part 332 funnel-shaped. The cross-section of the lower part 333 along the stacking direction of the photovoltaic module 1 is rectangular, making the lower part 333 cylindrical. The upper part 332 is funnel-shaped, so that the hot-melted first adhesive film 20 can flow more fully and faster under the action of gravity. At the same time, the funnel-shaped inclined structure can disperse the impact force to the entire surface, avoid stress concentration, and buffer the instantaneous impact on the front of the photovoltaic module 1. The lower part 333 is cylindrical, which has high torsional stiffness and can bear pressure evenly, avoiding local buckling or instability, and can strengthen the overall structural strength of the photovoltaic module 1.

[0089] According to the photovoltaic module 1 provided in the embodiments of this application, by setting the upper part 332 and the lower part 333, the overall structural strength of the photovoltaic module 1 can be improved while ensuring the fluidity of the hot-melt first adhesive film 20.

[0090] In some embodiments, the first substrate 31, the second substrate 32, and the support component 33 can be integrally injection molded.

[0091] In this embodiment, the three-layer structure of the first substrate 31, the support component 33, and the second substrate 32 is integrally injection molded, which has high production efficiency, less material waste, and lower cost. At the same time, it avoids assembly errors and improves the overall precision and consistency of the reinforcing component 30. Since there are no assembly seams, it has high structural strength and reliability, ensuring the structural strength of the photovoltaic module 1 and a long service life of the photovoltaic module 1.

[0092] According to the embodiments of this application, the photovoltaic module 1 is manufactured by integral injection molding of the first substrate 31, the second substrate 32 and the support component 33, which has high production efficiency, low cost, avoids assembly errors, ensures the structural strength of the photovoltaic module 1, and has a long service life.

[0093] In some embodiments, the front panel 10, the first adhesive film 20, the reinforcing component 30, the second adhesive film 40, the battery 50, the third adhesive film 60, and the back panel 70 stacked in sequence can be connected by heat fusion of the corresponding adhesive film between each adjacent pair.

[0094] In this embodiment, the photovoltaic module 1 is stacked sequentially in the following order: front panel 10, first adhesive film 20, reinforcing component 30, second adhesive film 40, battery 50, third adhesive film 60, and back panel 70. After stacking, hot pressing is performed to melt the first adhesive film 20, second adhesive film 40, and third adhesive film 60, thus bonding the front panel 10, reinforcing component 30, battery 50, and back panel 70. The first adhesive film 20 bonds the front panel 10 and reinforcing component 30 together, the second adhesive film 40 bonds the reinforcing component 30 and battery 50 together, and the third adhesive film 60 bonds the battery 50 and back panel 70 together. This bonding of the photovoltaic module 1 components together forms a whole with good integrity. The first adhesive film 20, second adhesive film 40, and third adhesive film 60 can also act as buffer layers while bonding adjacent components together, resulting in high structural strength of the photovoltaic module 1.

[0095] According to the photovoltaic module 1 provided in the embodiments of this application, by hot-melt connecting each adjacent pair of the front panel 10, the first adhesive film 20, the reinforcing component 30, the second adhesive film 40, the battery 50, the third adhesive film 60 and the back panel 70 stacked in sequence, the adjacent components are bonded together and a buffering effect is played. The photovoltaic module 1 has high structural strength and good integration.

[0096] In some embodiments, such as Figure 2 As shown, the reinforcing component 30 may have multiple supporting components 33.

[0097] Multiple support components 33 are spaced apart between the first substrate 31 and the second substrate 32.

[0098] In this embodiment, the diameter range of the maximum diameter of the upper part 332 of the support component 33 can be 2-10mm, and the distance between the outer edges of the maximum diameter of two adjacent upper parts 332 can be 5-20mm. While ensuring the structural strength of the photovoltaic module 1, the number of support components 33 can be reasonably set to reduce costs and improve economic efficiency.

[0099] For example, the diameter range of the upper part 332 of the support component 33 at its maximum diameter is 6 mm, and the distance between the outer edges of the maximum diameter between two adjacent upper parts 332 is 13 mm.

[0100] It should be noted that the number of supporting components 33 is proportional to the area of ​​photovoltaic module 1.

[0101] According to the photovoltaic module 1 provided in the embodiments of this application, by setting multiple support components 33 spaced apart between the first substrate 31 and the second substrate 32, the structural strength of the photovoltaic module 1 is guaranteed while the number of support components 33 is reasonably set, thereby reducing costs and improving economic efficiency.

[0102] This application also provides a photovoltaic system 1000.

[0103] like Figure 1 As shown, the photovoltaic system 1000 includes: photovoltaic module 1 and mounting bracket 2.

[0104] Photovoltaic module 1 is the photovoltaic module 1 described in the above embodiment.

[0105] Photovoltaic module 1 is installed on mounting bracket 2.

[0106] Mounting bracket 2 can be made of materials such as aluminum alloy, stainless steel, galvanized steel or fiber composite materials.

[0107] In this embodiment, the mounting bracket 2 can be made of aluminum alloy material. Aluminum alloy mounting brackets are lightweight, beautiful, durable and corrosion resistant.

[0108] In this embodiment, the mounting bracket 2 can be installed on a roof, balcony railing, vehicle roof, or other portable locations.

[0109] According to the photovoltaic system 1000 provided in the embodiments of this application, by installing the photovoltaic module 1, which is structurally strengthened by setting the reinforcing component 30, on the mounting bracket 2, the photovoltaic system 1000 has high impact resistance and load capacity when generating electricity, good stability and long life.
