Description

Technical Field

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

[0002] Solar cells, also known as photovoltaic cells, are semiconductor devices that directly convert sunlight into electrical energy. Because they are green and environmentally friendly products that do not cause pollution, and because solar energy is a renewable resource, solar cells are a new type of battery with broad development prospects.

[0003] Solar energy utilization relies on photovoltaic modules to absorb solar energy. These modules are typically installed in arrays in the field or on buildings to form a photovoltaic system.

[0004] In related technologies, the edges of the laminates of photovoltaic modules are supported on the frame. However, due to the large size of the laminates, they are prone to deformation under gravity and become concave. When the laminates are subjected to external mechanical stress (such as hail, falling rocks, sandstorms, and trampling), they are prone to microcracks or breakage, leading to photovoltaic module failure.

Detailed Implementation

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] See Figures 1 to 4 As shown, this application provides a photovoltaic module 10, including a laminate 11 and a frame member 12; the laminate 11 arches toward the light-receiving side of the laminate 11; the frame member 12 includes two first frames 121 disposed opposite to each other; the laminate 11 is located between the two first frames 121 and connected to the two first frames 121.

[0054] Specifically, see Figure 1 and Figure 3 As shown, the laminate 11 may have a rectangular structure; the two first borders 121 of the border member 12 may be disposed opposite each other on both sides of the width direction of the laminate 11; the border member 12 also includes two second borders 122, which may be disposed opposite each other on both sides of the length direction of the laminate 11; the first borders 121 and the second borders 122 are connected. The structure of the first border 121 and the structure of the second border 122 may be the same.

[0055] The photovoltaic module 10 provided in this application embodiment has a laminate 11 arched towards the light-receiving side of the laminate 11, with the laminate 11 located between and connected to the two first frame frames 121. This is equivalent to subjecting the backlight side of the laminate 11 to an upward compressive stress. Thus, when the laminate 11 is subjected to a downward impact force, the upward compressive stress on the backlight side of the laminate 11 can offset part of the downward impact force, reducing the probability of the laminate 11 developing microcracks or breaking, improving the impact resistance of the photovoltaic module 10, improving the structural stability and reliability of the photovoltaic module 10, and extending the service life of the photovoltaic module 10.

[0056] In one embodiment, see [reference] Figures 1 to 4 As shown, the photovoltaic module 10 also includes at least one support structure 3, which is disposed on the backlight side of the laminate 11. The support structure 3 is located between two first frame frames 121 and is connected to the two first frame frames 121. The side of the support structure 3 near the laminate 11 is provided with an arched portion 131 that arches toward the laminate 11. The arched portion 131 abuts against the laminate 11 so that the laminate 11 remains arched toward the light-receiving side.

[0057] Therefore, at least one support structure 3 can provide support for the laminate 11, so that the laminate 11 is kept arched towards the light-receiving side. This is equivalent to subjecting the back side of the laminate 11 to upward compressive stress. In this way, when the laminate 11 is subjected to downward impact force, the upward compressive stress on the back side of the laminate 11 can offset part of the downward impact force, reduce the probability of the laminate 11 developing microcracks or breaking, improve the impact resistance of the photovoltaic module 10, improve the structural stability and reliability of the photovoltaic module 10, and extend the service life of the photovoltaic module 10.

[0058] In one embodiment, see [reference] Figure 5 As shown, the first frame 121 includes a support portion 1211 and a main body portion 1212 arranged sequentially along the first direction X; the support portion 1211 has a receiving groove 1211a on one side along the second direction Y; the edge of the laminate 11 is disposed in the receiving groove 1211a; the support structure 3 is connected to the main body portion 1212; the first direction X is parallel to the height direction of the first frame 121; the second direction Y intersects with the first direction X, and the second direction Y is perpendicular to the third direction Z, and the third direction Z is parallel to the extension direction of the first frame 121.

[0059] Therefore, when installing the laminate 11 and the support structure 3, the edge of the laminate 11 is placed in the receiving groove 1211a on the bearing portion 1211 of the first frame 121; then the support structure 3 is placed between the main body portions 1212 of the two first frames 121, so that the support structure 3 is connected to the main body portion 1212, and the arched portion 131 of the support structure 3 abuts against the laminate 11, providing support for the laminate 11, so that the laminate 11 is kept arched towards the side away from the support structure 3. While realizing the encapsulation and fixation of the laminate 11, the impact resistance of the laminate 11 can be improved, and the probability of the laminate 11 cracking or breaking can be reduced, thereby improving the structural stability and reliability of the photovoltaic module 10 and extending the service life of the photovoltaic module 10.

[0060] In one embodiment, see [reference] Figure 5 As shown, the main body 1212 includes a supporting part 1212a and a second connecting part 1212b; the second connecting part 1212b connects the supporting part 1212a and the bearing part 1211; the supporting part 1212a includes a first protrusion 1212a1 extending out of the second connecting part 1212b along the second direction Y side, the end of the support structure 3 overlaps the first protrusion 1212a1, and the end of the support structure 3 is connected to the second connecting part 1212b.

[0061] Therefore, by having the end of the support structure 3 overlap the first protrusion 1212a1 and the end of the support structure 3 connected to the second connection 1212b, the connection reliability between the support structure 3 and the main body 1212 can be improved, thereby improving the structural stability and reliability of the photovoltaic module 10.

[0062] It should be noted that the support structure 3 and the first protrusion 1212a1 can be connected by fasteners or adhesives, and the support structure 3 and the second connecting part 1212b can also be connected by fasteners or adhesives. Fasteners include bolts; adhesives include structural adhesives.

[0063] In one embodiment, see [reference] Figure 6 As shown, the arched portion 131 is a first arched surface 131a located on the side of the support structure 3 near the laminate 11 and arching towards the laminate 11.

[0064] Therefore, by abutting the first arched surface 131a against the laminate 11, the laminate 11 can arch towards the side away from the supporting structure 3, and there is a large contact area between the laminate 11 and the first arched surface 131a. In this way, the impact force from the light-receiving side of the laminate 11 can be effectively offset, the probability of the laminate 11 developing microcracks or breaking can be effectively reduced, and the impact resistance of the photovoltaic module 10 can be improved.

[0065] In one embodiment, see [reference] Figure 6As shown, the surface of the support structure 3 away from the laminate 11 is a first flat surface 132, which is perpendicular to the first direction X and parallel to the height direction of the first frame 121.

[0066] Therefore, the geometric center of the self-supporting structure 3 points towards the first frame 121, and the distance between the first arched surface 131a and the first flat surface 132 along the height direction of the first frame 121 gradually decreases. This facilitates the installation of the support structure 3 on the backlight side of the laminate 11, allowing the support structure 3 to be located between and connected to the two first frames 121. Furthermore, by making the surface of the support structure 3 away from the laminate 11 the first flat surface 132, the support structure 3 can be stably attached to the first protrusion 1212a1 on the main body 1212 of the first frame 121, improving the connection reliability between the support structure 3 and the first frame 121, thereby enhancing the structural stability and reliability of the photovoltaic module 10.

[0067] In one embodiment, see [reference] Figure 7 As shown, at least a portion of the surface of the support structure 3 away from the laminate 11 arches towards the first arched surface 131a, forming a second arched surface 133a. Further, the second arched surface 133a and the first arched surface 131a are equally spaced along the first direction X; the first direction X is parallel to the height direction of the first frame 121.

[0068] This reduces the weight of the support structure 3, giving it a certain degree of flexibility, which makes it easier to install the support structure 3 on the backlight side of the laminate 11, so that the support structure 3 is located between the two first frame frames 121 and connected to the two first frame frames 121.

[0069] Furthermore, the radius of the first arched surface 131a and the radius of the second arched surface 133a are both between 8.05m and 42.45m.

[0070] Therefore, the bending radius of the laminate 11 after arching towards the light-receiving side is between 8.05m and 42.45m, which is equivalent to subjecting the back side of the laminate 11 to upward compressive stress. In this way, when the laminate 11 is subjected to downward impact force, the upward compressive stress on the back side of the laminate 11 can offset part of the downward impact force, reduce the probability of the laminate 11 developing microcracks or breaking, improve the impact resistance of the photovoltaic module 10, improve the structural stability and reliability of the photovoltaic module 10, and extend the service life of the photovoltaic module 10.

[0071] In one embodiment, see [reference] Figure 7As shown, the surface of the support structure 3 away from the laminate 11 includes a first sub-arched surface 133a1 and two second flat surfaces 133b; the two second flat surfaces 133b are located on both sides of the first sub-arched surface 133a1 along the second direction Y and are connected to the first sub-arched surface 133a1; the second flat surfaces 133b are perpendicular to the first direction X, the second direction Y intersects with the first direction X, and the second direction Y is perpendicular to the third direction Z; the first direction X is parallel to the height direction of the first frame 121; the third direction Z is parallel to the extension direction of the first frame 121.

[0072] Therefore, on the one hand, the weight of the support structure 3 can be reduced, allowing the support structure 3 to have a certain degree of deflection, which facilitates the installation of the support structure 3; on the other hand, when the support structure 3 overlaps with the first protrusion 1212a1 on the main body 1212 of the first frame 121, the second flat surface 133b of the support structure 3 contacts the first protrusion 1212a1, which improves the stability of the support structure 3 overlapping with the first protrusion 1212a1 on the main body 1212 of the first frame 121, thereby improving the connection reliability between the support structure 3 and the first frame 121, and thus improving the structural stability and reliability of the photovoltaic module 10.

[0073] In one embodiment, see [reference] Figure 8 and Figure 9 As shown, the support structure 3 includes a first connecting part 134; an arched part 131 protrudes from the first connecting part 134 on the side near the laminate 11, and the surface of the arched part 131 on the side near the laminate 11 is a third arched surface 131b arching towards the laminate 11; the first connecting part 134 is connected to two first frame parts 121.

[0074] Therefore, when installing the support structure 3, the first connecting part 134 is connected to the two first frame 121, and the third arched surface 131b of the arched part 131 abuts against the laminate 11, which allows the laminate 11 to arch towards the side away from the support structure 3. The laminate 11 and the third arched surface 131b have a large contact area, which can effectively offset the impact force from the light-receiving side of the laminate 11, effectively reduce the probability of the laminate 11 developing microcracks or breaking, and improve the impact resistance of the photovoltaic module 10.

[0075] In one embodiment, see [reference] Figure 8 As shown, the surface of the first connecting part 134 away from the laminate 11 is a third flat surface 134a, which is perpendicular to the first direction X; the first direction X is parallel to the height direction of the first frame.

[0076] Therefore, when the support structure 3 overlaps with the first protrusion 1212a1 on the main body 1212 of the first frame 121, the third flat surface 134a of the first connecting part 134 contacts the first protrusion 1212a1. This improves the stability of the support structure 3 overlapping with the first protrusion 1212a1 on the main body 1212 of the first frame 121, thereby improving the connection reliability between the support structure 3 and the first frame 121, and thus improving the structural stability and reliability of the photovoltaic module 10.

[0077] In one embodiment, see [reference] Figure 9 As shown, at least a portion of the surface of the first connecting portion 134 away from the laminate 11 arches toward the third arched surface 131b, forming a fourth arched surface 134b. Further, the fourth arched surface 134b and the third arched surface 131b are equally spaced along the first direction X; the first direction X is parallel to the height direction of the first frame 121.

[0078] This reduces the weight of the support structure 3, allowing it to have a certain degree of deflection, which facilitates its installation.

[0079] In one embodiment, see [reference] Figure 9 As shown, the surface of the first connecting portion 134 away from the laminate 11 includes a second sub-arched surface 134b1 and two fourth flat surfaces 134c. The two fourth flat surfaces 134c are located on both sides of the second sub-arched surface 134b1 along the second direction Y and are in contact with the second sub-arched surface 134b1. The fourth flat surfaces 134c are perpendicular to the first direction X, the second direction Y intersects with the first direction X, and the second direction Y is perpendicular to the third direction Z. The first direction X is parallel to the height direction of the first frame 121. The third direction Z is parallel to the extension direction of the first frame 121.

[0080] Therefore, on the one hand, the weight of the support structure 3 can be reduced, allowing the support structure 3 to have a certain degree of deflection, which facilitates the installation of the support structure 3; on the other hand, when the support structure 3 overlaps with the first protrusion 1212a1 on the main body 1212 of the first frame 121, the fourth flat surface 143c of the first connecting part 134 contacts the first protrusion 1212a1, which improves the stability of the support structure 3 overlapping with the first protrusion 1212a1 on the main body 1212 of the first frame 121, thereby improving the connection reliability between the support structure 3 and the first frame 121, and thus improving the structural stability and reliability of the photovoltaic module 10.

[0081] In one embodiment, see [reference] Figure 10 As shown, the laminate 11 has an arched structure, and the arch height h of the laminate 11 is between 5mm and 20mm.

[0082] In one embodiment, see [reference] Figure 10 As shown, the laminate 11 has an arched structure, and the bending radius R of the laminate 11 is between 8.05m and 42.45m.

[0083] In one embodiment, see [reference] Figure 3 and Figure 4 As shown, the laminate 11 includes a first substrate 111, a battery layer 112, and a second substrate 113 stacked sequentially in a direction away from the support structure 3; both the first substrate 111 and the second substrate 113 are hot-bent glass, and the bending radius of the first substrate 111 and the bending radius of the second substrate 113 are both between 8.05m and 42.45m.

[0084] Therefore, by making both the first substrate 111 and the second substrate 113 hot-bent glass, the first substrate 111 and the second substrate 113 can be easily made into an arch shape, so that the bending radius of the first substrate 111 and the bending radius of the second substrate 113 are both between 8.05m and 42.45m. This allows the laminate 11 to have an arched structure, so that the back side of the laminate 11 is subjected to upward compressive stress. In this way, when the laminate 11 is subjected to downward impact force, the upward compressive stress on the back side of the laminate 11 can offset part of the downward impact force, reduce the probability of the laminate 11 developing microcracks or breaking, improve the impact resistance of the photovoltaic module 10, improve the structural stability and reliability of the photovoltaic module 10, and extend the service life of the photovoltaic module 10.

[0085] It should be noted that the battery layer 112 may include battery cells, and the types of battery cells include, but are not limited to, passivated emitter rear cell (PERC), tunnel oxide passivated contact (TOPCon), intrinsic thin-film heterojunction (HJT), interdigitated back contact (IBC), perovskite cells, etc. The photovoltaic module 10 also includes a first encapsulant film (not shown) and a second encapsulant film (not shown). The first encapsulant film is disposed between the first substrate 111 and the battery layer 112, and the second encapsulant film may be disposed between the battery layer 112 and the second substrate 113. The materials used for the first and second encapsulant films include, but are not limited to: ethylene-vinyl acetate copolymer (EVA), polyolefin elastomer (POE), polyvinyl butyral (PVB), EPE (EVA-POE-EVA), EP (EVA-POE), or PEP (POE-EVA-POE).

[0086] In one embodiment, see [reference] Figure 3 and Figure 4 As shown, a wiring hole 14 is provided on the first substrate 111; the orthographic projection of the support structure 3 on the second substrate 113 overlaps with the orthographic projection of the wiring hole 14 on the second substrate 113.

[0087] This can improve the impact resistance of the photovoltaic module 10 in the area where the wiring hole 14 is located, reduce the probability of the laminate 11 developing microcracks or breaking in the area where the wiring hole 14 is located, and improve the reliability of the photovoltaic module 10.
