DETAILED DESCRIPTION

[0019] In order to better understand the technical solution of the present application, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0020] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0021] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0022] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0023] like Figure 1 As shown, an embodiment of the present application provides a photovoltaic component, including a photovoltaic module 1 and a line card 3, the photovoltaic module 1 includes a laminate 11 and a frame 12, the laminate 11 has a backlight surface 11a along its own thickness direction Z, the frame 12 is connected to the backlight surface 11a, the line card 3 is connected to one side of the frame 12, and the line card 3 is connected to the cable 2 of the photovoltaic module 1.

[0024] The photovoltaic module 1 includes a laminate 11 and a frame 12. The frame 12 is arranged on the backlight surface 11a of the laminate 11, that is, the frame 12 is arranged on the surface of the laminate 11 facing away from the sunlight, and the frame 12 can be located at the edge of the backlight surface 11a. One end of the line card 3 is fixed to the frame 12, and the other end of the line card 3 is fixed to the cable 2, that is, the line card 3 plays a fixing role on the cable 2, so that the line card 3 is fixed to one side of the frame 12.

[0025] Photovoltaic modules 1 can convert solar energy into electrical energy. Please also refer to Figure 2a and Figure 2b , the adjacent photovoltaic modules 1 can be electrically connected through the cable 2, wherein, of the two adjacent photovoltaic modules 1, one photovoltaic module 1 has a first junction box 61, and the other photovoltaic module 1 has a second junction box 62, and the interface of the cable 2 led out of the first junction box 61 (the interface can be a negative electrode interface) is connected with the interface of the cable 2 led out of the second junction box 62 (the interface can be a positive electrode interface), thereby realizing the electrical connection between the two adjacent photovoltaic modules 1. The cable 2 between the adjacent photovoltaic modules 1 can be connected to the above-mentioned line card 3.

[0026] Combination Figure 1 and Figure 3As shown, combined Figure 1 and Figure 3 As shown, the photovoltaic component may include a clamp 4 and a color steel tile 7, and the photovoltaic module 1 may be installed on the color steel tile 7 by the clamp 4. The line clamp 3 fixes the cable 2 on one side of the frame 12, that is, the line clamp 3 plays a suspending role on the cable 2, reducing the possibility of the cable 2 falling toward the color steel tile 7 under its own gravity, so that a certain distance can be maintained between the cable 2 and the color steel tile 7, avoiding direct contact between the cable 2 and the color steel tile 7, thereby reducing the possibility of the water on the color steel tile 7 contacting the cable 2 and causing the cable 2 to short-circuit, causing the electrical connection between the photovoltaic components to fail, and at the same time, it also reduces the possibility of the arc generated by the cable 2 burning through or corroding the color steel tile 7, so as to extend the service life of the color steel tile 7, thereby ensuring the stability, reliability and safety of the photovoltaic component.

[0027] By providing the above-mentioned frame 12, the structural strength of the photovoltaic module 1 can be improved, and the possibility of damage to the photovoltaic module 1 due to external forces during transportation, installation and use can be reduced, so as to extend the life of the photovoltaic module 1 and improve the working stability of the photovoltaic module 1. Compared with the solution of wrapping the frame 12 around the edge of the laminate 11 or arranging the frame 12 on the light-receiving surface of the laminate 11 (i.e., the surface of the laminate 11 facing the sunlight), the embodiment of the present application arranges the frame 12 on the backlight surface 11a of the laminate 11, which reduces the possibility of the frame 12 blocking the light-receiving surface of the laminate 11, that is, reduces the shading area, which is beneficial to improve the efficiency of the photovoltaic module 1, and further improves the reliability of the entire photovoltaic component.

[0028] The laminate 11 contains battery cells, and the types of battery cells include but are not limited to Passivated Emitter Rear Cell (PERC), Tunnel Oxide Passivated Contact (TOPCon), Heterojunction with Intrinsic Thin-film (HJT), Interdigitated Back Contact (IBC), perovskite cells, etc.

[0029] For PERC cells, along the thickness direction, PERC cells include the front surface metal silver electrode, the front surface silicon nitride passivation layer, the phosphorus layer emitter, the P-type base silicon layer, the local aluminum back field, the metal aluminum back electrode, and the back passivation layer (Al2O3 / SiNx). PERC cells use a passivation film to passivate the back, replacing the full aluminum back field, enhancing the internal back reflection of light in the silicon base, reducing the recombination rate on the back, and increasing the efficiency of the cell by 0.5%-1%.

[0030] For TOPCon cells, along the thickness direction, TOPCon cells include metal silver electrodes, front surface silicon nitride passivation layers, boron-doped emitters, N-type base silicon layers, diffused doping layers, ultra-thin silicon oxide, doped polysilicon, silicon nitride, and metal silver electrodes. The back of the cell is composed of an ultra-thin silicon oxide layer (1nm~2nm) and a phosphorus-doped microcrystalline amorphous mixed Si film, which together form a passivation contact structure. This structure can block the recombination of minority carrier holes and increase the open circuit voltage and short circuit current of the cell. The ultra-thin oxide layer allows majority electrons to tunnel into the polysilicon layer while blocking the recombination of minority carrier holes. The good passivation effect of ultra-thin silicon oxide and heavily doped silicon film causes the energy band on the silicon wafer surface to bend, thereby forming a field passivation effect, greatly increasing the probability of electron tunneling, and reducing the contact resistance, which increases the open circuit voltage and short circuit current of the cell, thereby improving the cell conversion efficiency.

[0031] For HJT cells, along the thickness direction, the HJT cells include a front low-temperature silver electrode, a front conductive film, an N-type amorphous silicon film, an intrinsic amorphous silicon film, an N-type base silicon layer, an intrinsic amorphous silicon film, a P-type amorphous silicon film, a back conductive film, and a back low-temperature silver electrode.

[0032] For IBC cells, along the thickness direction, IBC cells include silicon nitride anti-layer, N+ front surface field, N-type base silicon layer, P+ emitter, N+ back field, aluminum oxide passivation layer, silicon nitride anti-reflection layer, and metal silver electrode. IBC cells use ion implantation technology to obtain P and N regions with good uniformity and precisely controllable junction depth. There is no grid line blocking on the front of the cell, which can eliminate the shading current loss of the metal electrode and achieve the maximum utilization of incident photons. The short-circuit current can be increased by about 7% compared with conventional solar cells; due to the back contact structure, there is no need to consider the grid line blocking problem, and the grid line ratio can be appropriately widened, thereby reducing the series resistance and having a high fill factor; the surface passivation and surface light trapping structure can be optimized to obtain a lower front surface recombination rate and surface reflection.

[0033] For perovskite cells, along the thickness direction, the perovskite cell includes substrate material, conductive film, electron transport layer (titanium dioxide), perovskite absorption layer (hole transport layer), and metal cathode. Perovskite materials have a high light absorption coefficient and a long carrier diffusion distance. After the photons absorbed by the perovskite material are converted into electrons, they are easily collected by the electrode with low loss, so they can generate higher photoelectric voltage and current, making perovskite show higher photoelectric conversion efficiency.

[0034] In some embodiments, the line card 3 may be made of an insulating material with a certain elasticity, such as rubber, to facilitate the installation between the line card 3 and the frame 12 and the cable 2. In other embodiments, the line card 3 may also be made of an insulating material with a relatively high hardness to improve the structural strength of the line card 3, thereby improving the reliability of the line card 3.

[0035] like Figure 1 and Figure 4 As shown, in a possible implementation, the line card 3 includes a first slot body 31 , the cross-section of the first slot body 31 along the height direction Z of the line card 3 is U-shaped or V-shaped, and part of the structure of the cable 2 is located in the first slot body 31 and engaged with the first slot body 31 .

[0036] Part of the structure of the cable 2 is engaged in the first slot 31, so that the line card 3 plays a role in suspending and fixing the cable 2. The cross-section of the first slot 31 along the height direction Z of the line card 3 can be U-shaped, that is, the bottom of the first slot 31 can be arc-shaped, so that the shape of the first slot 31 can be better adapted to the shape of the cable 2, thereby improving the stability and reliability of the connection between the line card 3 and the cable 2, and reducing the possibility of the cable 2 coming out of the first slot 31. The cross-section of the first slot 31 along the height direction Z of the line card 3 can also be V-shaped, that is, the width of the first slot 31 gradually decreases from the top to the bottom, so that it is convenient for the first slot 31 to clamp the cable 2, so as to improve the stability and reliability of the connection between the line card 3 and the cable 2, and reduce the possibility of the cable 2 coming out of the first slot 31.

[0037] like Figure 1 and Figure 4 As shown, in a possible embodiment, the line card 3 includes a second slot body 32, the second slot body 32 is located on one side of the first slot body 31 along the length direction X of the line card 3, part of the structure of the frame 12 is located in the second slot body 32, the first slot body 31 has a first slot 311, the second slot body 32 has a second slot 321, the first slot 311 and the second slot 321 are both facing the laminate 11, or, one of the first slot 311 and the second slot 321 is facing the laminate 11, and the other is facing away from the laminate 11.

[0038] The first slot body 31 and the second slot body 32 may be arranged along the length direction X of the line card 3. In some embodiments, the first notch 311 and the second notch 321 may face the laminate 11 to facilitate the installation of the line card 3 and the frame 12, and at the same time, the cable 2 may be fixed between the line card 3 and the laminate 11, reducing the possibility of the cable 2 sagging under the action of its own gravity, thereby reducing the possibility of the cable 2 contacting the accumulated water on the color steel tile 7 and causing the cable 2 to short-circuit, and also reducing the possibility of the arc generated by the cable 2 burning through or corroding the color steel tile 7, so as to ensure the stability and reliability of the photovoltaic component.

[0039] In other embodiments, the first slot 311 and the second slot 321 are oriented in opposite directions. For example, one of the first slot 311 and the second slot 321 faces the laminate 11, and the other faces away from the laminate 11. This design facilitates guiding and prompting during the process of fixing the line card 3 to the frame 12 and the cable 2, reducing the possibility of reverse installation of the first slot body 31 and the second slot body 32, and facilitating the fixation of the first slot body 31 to the frame 12 and the second slot body 32 to the cable 2, thereby improving the accuracy of installation of the line card 3 and facilitating the installation efficiency of the line card 3.

[0040] like Figure 4 As shown, in a possible implementation, a through hole 33 is provided between the first slot body 31 and the second slot body 32, and the through hole 33 penetrates the line card 3 along the width direction Y of the line card 3. Providing the through hole 33 is conducive to reducing the dead weight of the line card 3 to meet the installation requirements of the photovoltaic component, and at the same time provides elastic deformation space for the first slot body 31 and the second slot body 32, so that the first slot body 31 and the second slot body 32 clamp the cable 2 and the frame 12 respectively, thereby improving the stability and reliability of the connection between the line card 3 and the cable 2 and the frame 12.

[0041] In some embodiments, the through hole 33 may not be connected to the first slot body 31 and the second slot body 32 to improve the structural strength of the first slot body 31 and the second slot body 32. In other embodiments, the through hole 33 may be connected to the first slot body 31 or the second slot body 32 to facilitate the processing and forming of the line card 3.

[0042] like Figure 4 As shown, in some embodiments, the line card 3 may further include a handheld portion 35, which may be located on one side of the first slot body 31 and / or one side of the second slot body 32, and extends along the length direction X of the line card 3. The handheld portion 35 provides an operating space for the operator's hand, that is, during the installation of the line card 3, the operator's hand may operate by grasping the handheld portion 35. By providing the handheld portion 35, the installation of the line card 3 is facilitated, and the installation efficiency of the line card 3 is improved.

[0043] like Figure 5 As shown, in a possible embodiment, the frame 12 includes a first portion 121, the first portion 121 is located in the second slot 32 and is engaged with the second slot 32, and the second slot 321 is provided with a limiting portion 34 on at least one side along the length direction X of the line card 3, and the limiting portion 34 is used to abut against the first portion 121 along the height direction Z of the line card 3 to limit the relative position of the frame 12 and the line card 3.

[0044] The limiting portion 34 can be located on one side or both sides of the second slot 321. When the limiting portion 34 abuts against the first portion 121 of the frame 12, the limiting portion 34 can limit the position of the frame 12 in the height direction Z of the line card 3, reducing the possibility of the first portion 121 escaping from the second slot 32, thereby improving the stability and reliability of the connection between the line card 3 and the frame 12.

[0045] like Figure 5 As shown, in a possible embodiment, the limiting portions 34 on both sides of the second slot 321 along the length direction X of the line card 3 are respectively a first limiting portion 341 and a second limiting portion 342, the frame 12 includes a cavity 122, the first limiting portion 341 is located in the cavity 122, a first protrusion 123 is provided inside the cavity 122, the first limiting portion 341 has a second protrusion 343, and the first protrusion 123 is used to abut against the second protrusion 343 along the length direction X of the line card 3 to limit the relative position of the frame 12 and the line card 3.

[0046] A first limiting portion 341 and a second limiting portion 342 are respectively provided on both sides of the second slot body 32. The first limiting portion 341 and the second limiting portion 342 can both abut against the first portion 121 located in the second slot body 32 to limit the position of the frame 12 in the height direction Z of the line card 3, thereby reducing the possibility of the frame 12 escaping from the second slot body 32.

[0047] Among them, the first limiting portion 341 has a second protrusion 343, and the second protrusion 343 can be raised along the height direction Z of the line card 3. The second protrusion 343 can abut against the first protrusion 123 inside the cavity 122 to limit the position of the frame 12 in the length direction X of the line card 3, further improve the stability and reliability of the connection between the line card 3 and the frame 12, and reduce the possibility of the frame 12 escaping from the second slot 32.

[0048] like Figure 6 As shown, in a possible embodiment, the photovoltaic component includes a color steel tile (not shown in the figure), a clamp 4 and a connector 5, the clamp 4 is connected to the color steel tile, the frame 12 is connected to the clamp 4 through the connector 5, and the line card 3 is connected to the connector 5.

[0049] One end of the connector 5 can be fixedly connected to the clamp 4 by bolts, and the other end of the connector 5 is connected to the frame 12. The frame 12 is connected to the clamp 4 by the connector 5, which is conducive to improving the stability and reliability of the connection between the frame 12 and the clamp 4, and reducing the possibility of the photovoltaic component 1 and the clamp 4 being separated from each other, so as to achieve normal and stable operation of the photovoltaic component. The end of the connector 5 can be engaged with the second slot 32 of the line card 3 to achieve the connection between the line card 3 and the connector 5.

[0050] In some embodiments, the connector 5 is snap-fitted and fixed to the frame 12, so that the connector 5 limits the frame 12, reducing the possibility of the photovoltaic component 1 sliding or falling off the clamp 4 under the action of external force, thereby improving the stability and reliability of the connection between the photovoltaic component 1 and the clamp 4, and is beneficial to improving the wind resistance of the photovoltaic component 1, so as to achieve normal and stable operation of the photovoltaic component.

[0051] In other embodiments, the connector 5 and the frame 12 are movably connected, for example, the frame 12 can rotate relative to the connector 5. The photovoltaic module 1 will deform under the action of external forces such as wind. For example, under the action of external forces, the middle area of ​​the photovoltaic module 1 will bulge relative to the edge area in the direction of the external force. At this time, the frame 12 set at the edge of the photovoltaic module 1 will tend to rotate relative to the connector 5. Therefore, by making the connector 5 and the frame 12 movably connected, the possibility of stress concentration and breakage of the photovoltaic module 1 at the connection position between the frame 12 and the connector 5 when the photovoltaic module 1 is subjected to external forces can be reduced, which is conducive to improving the reliability of the photovoltaic module 1 and extending the service life of the photovoltaic module 1.

[0052] like Figure 6 As shown, in a possible implementation manner, the connecting member 5 includes a hook-shaped portion 51 , the hook-shaped portion 51 is connected to the frame 12 , the hook-shaped portion 51 is located in the second slot body 32 , and is engaged with the second slot body 32 .

[0053] The shape of the hook-shaped portion 51 is similar to a "C" shape, and the connector 5 can be movably connected to the frame 12 through the hook-shaped portion 51. Specifically, when the photovoltaic module 1 is deformed under the action of external forces such as wind, part of the structure of the frame 12 can rotate in the hook-shaped portion 51 to reduce the possibility of stress concentration and breakage of the photovoltaic module 1 at the connection position between the frame 12 and the connector 5. The hook-shaped portion 51 is engaged with the second slot 32 to improve the stability and reliability of the connection between the line card 3 and the connector 5, so that the line card 3 can reliably suspend and fix the cable 2.

[0054] like Figure 6 As shown, in a possible embodiment, the hook-shaped portion 51 includes a first arc segment 511 and a second arc segment 512 connected to the first arc segment 511, the second groove body 32 includes a first arc wall 322 and a second arc wall 323 connected to the first arc wall 322, the first arc segment 511 abuts against the first arc wall 322, and the second arc segment 512 abuts against the second arc wall 323.

[0055] The first arc segment 511 and the second arc segment 512 can be connected to form a structure similar to a "C" shape, so as to facilitate the movable connection between the frame 12 and the hook-shaped portion 51. The second slot body 32 can have a first arc wall 322 corresponding to the shape of the first arc segment 511 and a second arc wall 323 corresponding to the shape of the second arc segment 512. The first arc segment 511 fits with the first arc wall 322, and the second arc segment 512 fits with the second arc wall 323, so that the hook-shaped portion 51 can be clamped in the second slot body 32, reducing the possibility of the hook-shaped portion 51 escaping from the second slot body 32, thereby improving the connection stability and reliability between the line card 3 and the connector 5.

[0056] like Figure 4 As shown, in a possible implementation, the width W of the line card 3 satisfies: 15mm≤W≤30mm. The width W of the line card 3 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm, 28mm, 29mm or 30mm, and of course it can also be other values ​​within the above range. When the width of the line card 3 is too small, for example, W is less than 15mm, the volume of the line card 3 is small, its structural strength is low, and the load it can bear is low, so it cannot provide a reliable fixing effect for the cable 2, causing the cable 2 to easily fall off the line card 3. When the width of the line card 3 is too large, for example, W is greater than 30mm, the volume of the line card 3 is too large, and its weight also increases, resulting in an increase in the weight of the photovoltaic component 1, which is difficult to meet the installation requirements of the photovoltaic component, thereby affecting the normal use of the photovoltaic component. Therefore, the width W of the line card 3 is designed to be 15mm≤W≤30mm, so that the line card 3 has a more reasonable volume and weight, and also has a higher structural strength, thereby providing a reliable fixing effect for the cable 2, reducing the possibility of the cable 2 falling toward the color steel tile 7, and thereby improving the reliability of the photovoltaic component.

[0057] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
