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] The present application embodiment provides a photovoltaic component, such as Figure 1 and Figure 2 As shown, the photovoltaic component includes a clamp 10, a color steel tile 20, a photovoltaic module 30 and a fixing 40. A plurality of color steel tiles 20 are installed on the ground or the main body of the building through a bracket 60. The clamp 10 is fixed to the color steel tile 20. The fixing 40 is connected to the photovoltaic module 30 and the clamp 10 respectively, so as to install the photovoltaic module 30 on the color steel tile 20, so as to use solar energy to generate electricity to meet daily use needs. Among them, the main body of the building includes but is not limited to the roof and wall of a factory building, a warehouse and other buildings of a production enterprise. This embodiment is described by taking the roof as the main body of the building as an example.

[0024] The connection structure between the clamp 10 and the color steel tile 20 is first described in detail below: like Figure 1 As shown, along the first direction X, two adjacent color steel tiles 20 overlap each other and are bent to form a locking edge 201. The clamp 10 includes a first clamping portion 1 and a second clamping portion 2, and the first clamping portion 1 and the second clamping portion 2 are used to clamp the locking edge 201 of the color steel tile 20 together so that the clamp 10 can be fixed to the color steel tile 20. Figure 3 and Figure 4As shown, the first clamping part 1 is provided with a first clamping arm 12, and the second clamping part 2 is provided with a second clamping arm 22. A clamping space 120 is formed between the first clamping arm 12 and the second clamping arm 22 along the first direction X, and at least part of the locking edge 201 is accommodated in the clamping space 120. Specifically, the first clamping arm 12 includes a first body 121 and a second body 122, and the second clamping arm 22 includes a third body 221 and a fourth body 222. The second body 122 and the fourth body 222 both extend along the height direction Z of the clamp 10, and the second body 122 and the fourth body 222 jointly clamp the locking edge 201 along the first direction X to improve the connection stability between the clamp 10 and the locking edge 201.

[0025] In a specific embodiment, Figure 3 and Figure 4 As shown, a first corrugated structure 124 is provided on one side surface of the second body 122 facing the clamping space 120, and / or a second corrugated structure 224 is provided on one side surface of the fourth body 222 facing the clamping space 120. The first corrugated structure 124 can increase the friction between the locking edge 201 and the second body 122, which is beneficial to improving the installation stability of the clamp 10; similarly, the second corrugated structure 224 can increase the friction between the locking edge 201 and the fourth body 222, which is beneficial to improving the installation stability of the clamp 10. When the first corrugated structure 124 and the second corrugated structure 224 are provided at the same time, the risk of the clamp 10 moving relative to the locking edge 201 can be further reduced, thereby improving the connection reliability between the clamp 10 and the locking edge 201.

[0026] In a specific embodiment, Figure 1 and Figure 4 As shown, the second clamping arm 22 is further provided with a support portion 223 fixedly connected to the fourth body 222, and the support portion 223 extends obliquely in a direction away from the fourth body 222 along the first direction X, gradually away from the third body 221. When the clamp 10 clamps the locking edge 201, the end of the support portion 223 away from the fourth body 222 can overlap the surface of the color steel tile 20, which is beneficial to improve the structural stability of the second clamping portion 2, reduce the risk of the second clamping portion 2 tilting, and thus help improve the installation stability of the clamp 10.

[0027] In a specific embodiment, Figure 3 and Figure 4As shown, along the height direction Z of the clamp 10, an extension section 123 is provided at one end of the second body 122 away from the first body 121, and the extension section 123 extends along the first direction X toward the direction close to the fourth body 222. On the one hand, by providing the extension section 123, the distance between the bottom end of the second body 122 and the bottom end of the fourth body 222 can be reduced, which is conducive to improving the clamping of the clamp 10 on the locking edge 201; on the other hand, the extension section 123 can overlap the surface of the color steel tile 20, which is conducive to improving the structural stability of the first clamping part 1 and reducing the risk of the first clamping part 1 tilting, thereby facilitating the installation stability of the clamp 10.

[0028] Furthermore, a hook structure is provided at one end of the extension section 123 facing the fourth body 222 , and the hook structure can press at least a portion of the locking edge 201 against the fourth body 222 , thereby improving the clamping effect of the clamp 10 on the locking edge 201 .

[0029] In a specific embodiment, Figure 3 and Figure 4 As shown, the first clamping portion 1 is further provided with a first mounting portion 11 and a first limiting section 13. The first mounting portion 11 extends along the first direction X and is used to provide support for the fixing member 40. The first limiting section 13 and the first body 121 are spaced apart along the first direction X, and the first limiting section 13 and the first body 121 are respectively fixedly connected to the first mounting portion 11. The second clamping portion 2 is further provided with a second mounting portion 21 extending along the first direction X. The second mounting portion 21 is fixedly connected to the third body 221. Along the first direction X, the two ends of the second mounting portion 21 are respectively abutted and matched with the first body 121 and the first limiting section 13, that is, the first clamping portion 1 can wrap the second mounting portion 21. The first body 121 and the first limiting section 13 can work together to limit the second mounting portion 21 from moving along the first direction X, thereby preventing the first clamping portion 1 and the second clamping portion 2 from moving relative to each other in the first direction X, so as to improve the connection stability and reliability between the first clamping portion 1 and the second clamping portion 2, thereby facilitating the clamping effect of the clamp 10 on the color steel tile 20. On the other hand, when installing the clamp 10, the first clamping portion 1 and the second clamping portion 2 can be pre-positioned by the limiting effect of the first body 121 and the first limiting section 13 on the second mounting portion 21, so as to ensure the relative position relationship between the first clamping portion 1 and the second clamping portion 2, thereby facilitating the assembly efficiency of the clamp 10.

[0030] like Figure 3 and Figure 4As shown, the first limiting section 13 includes a vertical portion 131 and a bent portion 132, the vertical portion 131 extends along the height direction Z of the clamp 10, the bent portion 132 is located at one end of the vertical portion 131 away from the first mounting portion 11, and the bent portion 132, the vertical portion 131 and the first mounting portion 11 form a limiting groove 133. The second mounting portion 21 is provided with a protruding end 211, at least part of which is accommodated in the limiting groove 133, and the limiting groove 133 limits the protruding end 211 in the height direction Z of the clamp 10, thereby preventing the first clamping portion 1 and the second clamping portion 2 from moving relative to each other along the height direction Z of the clamp 10, so as to further improve the connection stability and reliability between the first clamping portion 1 and the second clamping portion 2. Specifically, the protruding end 211 can be a curved surface structure, and accordingly, the limiting groove 133 can also be set to a curved surface structure. This makes it more convenient to install and match the first clamping part 1 and the second clamping part 2, and is not easy to cause wear, which is beneficial to improving the service life of the first clamping part 1 and the second clamping part 2.

[0031] In addition, in this embodiment, a bending portion 132 is provided to form a limiting groove 133 together with the vertical portion 131 and the first mounting portion 11, rather than directly opening a groove on the vertical portion 131 to form the limiting groove 133, so as to avoid affecting the structural strength of the vertical portion 131, which is also beneficial to improving the service life of the first clamping portion 1.

[0032] In a specific embodiment, Figure 3 As shown, along the first direction X, at least one end of the first mounting portion 11 is provided with a reinforcement section 111, and the reinforcement section 111 extends downward along the height direction Z of the clamp 10. By providing the reinforcement section 111, the structural strength of both ends of the first mounting portion 11 along the first direction X can be enhanced, and the risk of bending or damage of the end of the first mounting portion 11 is reduced, which is conducive to improving the service life of the first clamping portion 1.

[0033] In a specific embodiment, Figure 1 As shown, the clamp 10 further includes a fastener 3, and along the height direction Z of the clamp 10, the fastener 3 sequentially passes through the second mounting portion 21 and the first mounting portion 11, so as to fix the first clamping portion 1 with the second clamping portion 2. The first clamping portion 1 and the second clamping portion 2 can be fixedly connected only by the fastener 3, which reduces the number of parts of the clamp 10, simplifies the structure of the clamp 10, and is conducive to improving the structural compactness and assembly efficiency of the clamp 10.

[0034] like Figure 1 As shown, the first body 121 and the third body 221 are respectively bent along the first direction X toward a direction away from the clamping space 120, so that the end of the fastener 3 can be accommodated in the clamping space 120. Specifically, as Figure 4As shown, the second clamping portion 2 is further provided with a second limiting section 23 extending along the height direction Z of the clamp 10, and the second limiting section 23 is fixedly connected to the second mounting portion 21. The second limiting section 23 and the third body 221 are spaced apart along the first direction X, and the second limiting section 23 is used to cooperate with the third body 221 to jointly limit the movement of the fastener 3 along the first direction X, which is beneficial to improve the installation stability of the fastener 3. In addition, when the second limiting section 23 is provided, the second clamping portion 2 can wrap at least part of the fastener 3, which facilitates the pre-positioning between the fastener 3 and the second clamping portion 2, and is beneficial to improve the installation efficiency of the clamp 10. Among them, the fastener 3 can be a bolt.

[0035] Next, the connection structure between the fixing member 40 and the photovoltaic module 30 and the clamp 10 is described in detail: Combination Figure 2 and Figure 5 As shown, the photovoltaic assembly 30 includes a laminate 301 and a frame 302. The photovoltaic assembly 30 includes a light-facing surface 30A and a backlight surface 30B that are relatively distributed along the thickness direction Z thereof. The light-facing surface 30A faces the light source and is used to receive direct sunlight. The backlight surface 30B faces away from the light source. The frame 302 is fixedly connected to the backlight surface 30B. The frame 302 can support the laminate 301, reducing the risk of the laminate 301 being damaged by external forces during transportation, installation, and use, thereby extending the service life of the laminate 301 and improving the overall rigidity and working stability of the photovoltaic assembly 30. Moreover, when the frame 302 is installed on the backlight surface 30B, it will not block the light-facing surface 30A, thereby increasing the effective area on the light-facing surface 30A for absorbing sunlight, thereby improving the absorption efficiency of the photovoltaic assembly 30 for sunlight, which is beneficial to improving the photoelectric conversion efficiency of the photovoltaic assembly 30, and further beneficial to improving the output power of the photovoltaic component. Among them, the frame 302 includes a first side 302A, a second side 302B and a third side 302C, the second side 302B is fixedly connected to the first side 302A and the third side 302C respectively, the first side 302A, the second side 302B and the third side 302C form a cavity 303D, and the first side 302A is bonded and fixed to the backlight surface 30B by structural adhesive 303.

[0036] Among them, combined Fig. 9As shown, the laminate 301 includes a battery layer 301A, a front plate 301B, a back plate 301C and a film layer 301D. The battery layer 301A includes a plurality of battery strings connected in series or in parallel, each battery string is formed by a plurality of battery cells 301Aa (including but not limited to monocrystalline silicon battery cells and polycrystalline silicon battery cells) connected in series, and two adjacent battery cells 301Aa are connected by welding strips 301Ab; the front plate 301B is located on the light-facing side of the battery layer 301A, and is used to protect the surface of the battery layer 301A and reduce the risk of damage to the battery cells 301Aa; the back plate 301C is located on the backlight side of the battery layer 301A, and has the function of blocking water vapor and insulating protection; the film layer 301D includes a first film layer 301Da and a second film layer 301 Db, along the thickness direction Z of the laminate 301, the first adhesive film layer 301Da is located between the front panel 301B and the battery layer 301A, and is used to achieve a fixed connection between the front panel 301B and the battery layer 301A, and the second adhesive film layer 301Db is located between the battery layer 301A and the back panel 301C, and is used to achieve a fixed connection between the battery layer 301A and the back panel 301C. The first adhesive film layer 301Da and the second adhesive film layer 301Db can also play a certain supporting and protective role for the battery layer 301A, ensuring that the photovoltaic module has good mechanical strength and reducing the impact of hail impact, wind, mechanical vibration and the like.

[0037] The present embodiment does not limit the structure of the battery cell 301Aa. The types of the battery cell 301Aa 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 battery, etc.

[0038] For PERC cells, along the thickness direction, the PERC cell includes a front surface metal silver electrode, a front surface silicon nitride passivation layer, a phosphorus layer emitter, a P-type base silicon layer, a local aluminum back field, a metal aluminum back electrode, a back passivation layer (Al 2 O 3 / SiNx). PERC cells use a passivation film to passivate the back side, replacing the all-aluminum back side field, enhancing the internal back reflection of light in the silicon substrate, reducing the recombination rate on the back side, and increasing the efficiency of the cell by 0.5%-1%.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] like Figure 2 and Figure 6As shown, the fixing member 40 includes a fixing portion 401, which is overlapped with the first mounting portion 11 and fixedly connected with the clamp 10 through the fastener 3, which can reduce parts, simplify the structure of the photovoltaic component, and improve the installation efficiency of the fixing member 40 and the clamp 10. The fixing portion 401 has a first limiting protrusion 404 and a second limiting protrusion 405 arranged at intervals along the second direction Y. When the fixing member 40 is fixedly connected with the clamp 10, the first limiting protrusion 404 and the second limiting protrusion 405 can respectively abut and cooperate with the two ends of the first mounting portion 11 along the second direction Y to prevent the clamp 10 and the fixing member 40 from relative movement along the second direction Y, which is conducive to improving the connection stability between the clamp 10 and the fixing member 40.

[0044] Along the second direction Y, the two ends of the fixing portion 401 are respectively provided with a first connection portion 402 and a second connection portion 403. One of the two photovoltaic components 30 adjacent to each other along the second direction Y is connected to the first connection portion 402, and the other is connected to the second connection portion 403. Both the first connection portion 402 and the second connection portion 403 are curved structures, and the curved structures can extend into the cavity 302D, so that the two photovoltaic components 30 adjacent to each other along the second direction Y can form a movable connection with the fixing member 40 respectively.

[0045] Specifically, when the first connection part 402 is connected to the frame 302, the first side 302A and the third side 302C are mutually limited with the first connection part 402 along the height direction Z of the clamp 10 to limit the movement of the photovoltaic assembly 30 along the height direction Z of the clamp 10; the second side 302B is limited with the first connection part 402 along the second direction Y to limit the movement of the photovoltaic assembly 30 along the second direction Y, which is conducive to improving the installation stability of the photovoltaic assembly 30. The first connection part 402 is also provided with a receiving space 406, and at least part of the third side 302C extends into the receiving space 406. The photovoltaic assembly 30 will deform under the action of external force (such as wind). For example, the middle part of the photovoltaic assembly 30 will be arched upward relative to the edge part. At this time, the frame 302 will have a tendency to rotate relative to the fixing member 40. If the frame 302 is fixedly connected to the fixing member 40, the edge part of the photovoltaic assembly 30 is prone to stress concentration, resulting in the fragmentation of the photovoltaic assembly 30, affecting the normal use of the entire photovoltaic component. Therefore, the embodiment of the present application can reduce the possibility of stress concentration and breakage of the photovoltaic assembly 30 at the connection position between the frame 302 and the fixing member 40 when the photovoltaic assembly 30 is subjected to external force by movably connecting the fixing member 40 and the frame 302, thereby helping to improve the reliability of the photovoltaic assembly 30 and extend the service life of the photovoltaic assembly 30.

[0046] The connection structure between the second connection portion 403 and the frame 302 of another photovoltaic module 30 is the same as the connection between the first connection portion 402 and the frame 302 described above, and will not be repeated here.

[0047] It should be noted that the first direction X and the second direction Y are perpendicular to each other, the second direction Y is specifically the length direction of the locking edge 201, and the first direction X is specifically the direction perpendicular to the locking edge 201. In this embodiment, the length direction of the photovoltaic module 30 is parallel to the first direction X, and the width direction of the photovoltaic module 30 is parallel to the second direction Y.

[0048] In this embodiment, the width direction of the photovoltaic component 30 is parallel to the length direction (second direction Y) of the lock edge 201, and the fixing member 40 connects the clamp 10 and the photovoltaic component 30 along the second direction Y. There is no need to make the width of the photovoltaic component 30 consistent with the width of the color steel tile 20, so that the photovoltaic component 30 can be adapted to color steel tiles 20 of different widths. That is, this embodiment does not limit the version structure of the color steel tile 20 and has a high degree of flexibility.

[0049] In this embodiment, Figure 2 As shown, the fixing member 40 may be an integrated structure, that is, the fixing portion 401 , the first connecting portion 402 and the second connecting portion 403 are integrally formed.

[0050] Or, if Figure 7 and Figure 8 As shown, the fixing member 40 may also be a split structure, including a first sub-fixing member 40A and a second sub-fixing member 40B stacked along the height direction Z of the clamp 10. The first sub-fixing member 40A is provided with a first sub-fixing portion 401A, and the second sub-fixing member 40B is provided with a second sub-fixing portion 401B. The first sub-fixing portion 401A and the second sub-fixing portion 401B are detachably connected, and the first sub-fixing portion 401A and the second sub-fixing portion 401B are fixedly connected to the clamp 10 through the fastener 3. Among them, the first limiting protrusion 404 is provided on the first sub-fixing portion 401A, and the second limiting protrusion 405 is provided on the second sub-fixing portion 401B; along the second direction Y, the first connecting portion 402 is provided at one end of the first sub-fixing portion 401A away from the second sub-fixing portion 401B, and the second connecting portion 403 is provided at one end of the second sub-fixing portion 401B away from the first sub-fixing portion 401A.

[0051] The integrated fixing component 40 has a small movable space in the second direction Y and is inconvenient to disassemble. Therefore, when the fixing component 40 is set to a split structure, it is more convenient to install and disassemble the fixing component 40, and the installation and disassembly of a single photovoltaic module 30 can be realized.

[0052] In a specific embodiment, Figure 2As shown, the photovoltaic component also includes a pressing block 50. The pressing block 50 is stacked on the fixing member 40 along the height direction Z of the clamp 10, and is fixedly connected with the fixing member 40 and the clamp 10 through the fastener 3. The pressing block 50 can cooperate with the first mounting portion 11 to limit the movement of the fixing member 40 along the height direction Z of the clamp 10, which is beneficial to improve the installation stability of the fixing member 40. Moreover, along the second direction Y, the two ends of the pressing block 50 extend in the direction close to the frame 302, and can respectively abut and cooperate with the second edges 302B of the two adjacent frames 302, so as to simultaneously limit the two adjacent photovoltaic modules 30 along the second direction Y, which is beneficial to further improve the installation stability of the photovoltaic module 30 and reduce the risk of the photovoltaic module 30 being separated from the fixing member 40.

[0053] In this embodiment, the installation process of the clamp 10, the fixing member 40, the pressing block 50 and the photovoltaic module 30 is as follows: first, the fastener 3 is passed through the second mounting portion 21 and the first mounting portion 11 in sequence, and then the first clamp arm 12 and the second clamp arm 22 are installed on the locking edge 201, and then the fixing portion 401 of the fixing member 40 is overlapped on the surface of the first mounting portion 11, and the fastener 3 is passed through the fixing portion 401; then the frame 302 of the two photovoltaic modules 30 are respectively connected to the first connecting portion 402 and the second connecting portion 403, and finally the pressing block 50 is placed on the surface of the fixing member 40, and the fastener 3 is passed through the pressing block 50; finally, the fastener 3 is locked.

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.
