[0031] With the increasing popularity of building photovoltaic integration, photovoltaic components (photovoltaic tiles) that can replace traditional tiles have emerged in order to better integrate with the building surface. Photovoltaic components can be flat photovoltaic components or curved photovoltaic components. Compared with flat photovoltaic components, curved photovoltaic components can replace traditional tiles due to their unique shape, and have both aesthetics and power generation functions. However, when curved photovoltaic components overlap each other, there will be gaps between adjacent curved photovoltaic components. On rainy days, rainwater will enter the gaps and pass through the gaps into the interior of the building. In order to solve this problem, an embodiment of the present application provides a carrier 100 ( Figure 1 As shown), curved photovoltaic module 1000 ( Figure 3 The above) and photovoltaic building surface 10000 ( Figure 5 shown).

[0032] See also Figures 1 to 3 The carrier 100 of the embodiment of the present application includes a plurality of carriers 10, which are connected in sequence in a first direction X and overlapped in sequence in a second direction Y. Each carrier 10 is provided with a first groove 11, and the first groove 11 is used to install the curved photovoltaic element 300. The carrier 10 has a first end 13 and a second end 15 opposite to each other in the first direction X. The first end 13 is provided with a mounting portion 131, and the second end 15 is provided with a coupling portion 151. The mounting portion 131 of one carrier 10 is combined with the coupling portion 151 of another carrier 10 so that two adjacent carriers 10 are connected in the first direction X, and the first direction X intersects with the second direction Y.

[0033] Specifically, see Figure 1 , the carrier 100 is a structure for loading other components, and the carrier 100 of the present application is used to load the curved photovoltaic component 300. The number of carriers 10 in the carrier 100 may be, but is not limited to, two, three, four or more. Each carrier 10 is used to load a curved photovoltaic component 300. The carrier 10 may be die-casted from a metal material or a polymer material. Among them, the metal material may be, but is not limited to, aluminum alloy or titanium alloy, and the polymer material may be, but is not limited to, epoxy resin, bakelite or plastic, etc. The carrier 10 has a certain strength, so that it can stably carry the curved photovoltaic component 300. The curved photovoltaic component 300 of the present application is installed on the roof, so that the carrier 10 is also a part of the roof structure. In the case where the carrier 10 is the above-mentioned polymer material and metal material, the carrier 10 is a flame-retardant material, and the windproof and fireproof properties of the carrier 10 are good, thereby improving the safety level of the roof structure.

[0034] See also Figure 3 The curved photovoltaic element 300 is used to convert light energy into electrical energy to power other components, and can be used as a structure of a building component. For example, the curved photovoltaic element 300 can power household appliances, energy storage power supplies, street lamps and other equipment. The curved photovoltaic element 300 can generate electricity while also taking into account the aesthetics of the building.

[0035] See also Figure 1 and Figure 2The first groove 11 is a spatial structure for loading the curved photovoltaic element 300. The opening area of ​​the first groove 11 is at least larger than the area of ​​the curved photovoltaic element 300. Preferably, the opening area of ​​the first groove 11 is the same as the area of ​​the curved photovoltaic element 300, so that the curved photovoltaic element 300 can be stably installed on the carrier 10. The curved photovoltaic element 300 will not shake in the carrier 10 or even fall off from the carrier 10.

[0036] See also Figure 1 and Figure 2 , the mounting portion 131 is a structure for connecting with the coupling portion 151. In the first direction X, among two adjacent carriers 10, the mounting portion 131 of one carrier 10 is coupled with the coupling portion 151 of the other carrier 10, so that the two adjacent carriers 10 can be firmly connected, and the connection method of the two adjacent carriers 10 is relatively simple. When two adjacent carriers 10 are connected by the mounting portion 131 and the coupling portion 151, the two adjacent carriers 10 will not move relative to each other, so that after multiple carriers 10 and multiple curved photovoltaic components 300 are installed on the roof, the safety performance of the roof is relatively high (the carriers 10 and the curved photovoltaic components 300 will not have the risk of falling). In addition, the connection between the mounting portion 131 and the coupling portion 151 is relatively tight, and there will be no gap between the two adjacent carriers 10 in the first direction X, so that rainwater will not enter the interior of the building from the gap on rainy days, and the waterproof performance between the multiple carriers 10 is relatively good.

[0037] See also Figure 3 Generally, the curved photovoltaic element 300 is installed on the roof at an angle. The first direction X and the second direction Y of the present application are perpendicular to each other. In the second direction Y, a plurality of carriers 10 are overlapped in sequence, so that a plurality of curved photovoltaic elements 300 are overlapped in sequence. In the thickness direction of the curved photovoltaic element 300, the edge of the carrier 10 located above is overlapped on the carrier 10 below. On rainy days, rainwater flows down along the inclined plurality of curved photovoltaic elements 300, which can prevent rainwater from flowing into the interior of the building from the gap between the two carriers 10 overlapped in the second direction Y. Preferably, the gap between the two carriers 10 overlapped in the second direction Y can be filled with waterproof glue, so as to further prevent rainwater from flowing into the interior of the building from the gap between the two carriers 10 overlapped in the second direction Y, and the waterproof effect of the carrier 100 is better.

[0038] In the carrier 100 of the embodiment of the present application, the mounting portion 131 of one carrier 10 is combined with the coupling portion 151 of another carrier 10, so that the two adjacent carriers 10 in the first direction X are firmly connected. In addition, the mounting portion 131 and the coupling portion 151 are tightly connected, and there is no gap between the two adjacent carriers 10 in the first direction X. Rainwater will not enter the interior of the building through the gap on rainy days, and the waterproof effect of the carrier 100 is better.

[0039] The carrier 100 is further described below with reference to the accompanying drawings.

[0040] See also Figure 2 In some embodiments, one of the mounting portion 131 and the combining portion 151 is a protrusion 1311, and the other of the mounting portion 131 and the combining portion 151 is a slot 1511. When two adjacent carriers 10 in the first direction X are connected, the protrusion 1311 cooperates with the slot 1511.

[0041] Specifically, in one embodiment, the mounting portion 131 is a protrusion 1311, and the coupling portion 151 is a slot 1511. The protrusion 1311 and the slot 1511 are engaged with each other to connect two adjacent carriers 10 in the first direction X, and the method of connecting the carriers 10 is relatively simple. After the protrusion 1311 is engaged with the slot 1511, there can be no gap between the two adjacent carriers 10 in the first direction X, so that the waterproof effect between the multiple carriers 10 is better. In the case where the mounting portion 131 is a protrusion 1311, the mounting portion 131 can be an integral structure or a split structure with the carrier 10 body. In the case where the mounting portion 131 and the carrier 10 body are an integral structure, the mounting portion 131 and the carrier 10 body are integrally formed, and the material of the mounting portion 131 and the carrier 10 body is the same. In the case where the mounting portion 131 and the carrier 10 body are split structures, the mounting portion 131 can be detachably or non-detachably mounted on the carrier 10 body. At this time, the material of the mounting portion 131 can be the same as or different from the material of the carrier body 10. The detachable mounting method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable mounting method includes but is not limited to welding, gluing connection or interference fit, etc.

[0042] In another embodiment, the mounting portion 131 is a slot 1511, and the coupling portion 151 is a protrusion 1311. When the coupling portion 151 is a protrusion 1311, the coupling portion 151 may be an integral structure or a split structure with the carrier 10 body. When the coupling portion 151 and the carrier 10 body are an integral structure, the coupling portion 151 and the carrier 10 body are integrally formed, and the coupling portion 151 and the carrier 10 body are made of the same material. When the coupling portion 151 and the carrier 10 body are split structures, the coupling portion 151 may be detachably or non-detachably mounted on the carrier 10 body. At this time, the material of the coupling portion 151 may be the same as or different from the material of the carrier 10 body. Among them, the detachable mounting method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable mounting method includes but is not limited to welding, gluing connection or interference fit, etc.

[0043] The mounting portion 131 of the present application is a protrusion 1311, and the coupling portion 151 is a groove. The mounting portion 131 is a T-shaped protrusion 1311, and the corresponding coupling portion 151 is a T-shaped slot 1511. After the T-shaped protrusion 1311 is engaged with the T-shaped slot 1511, the connection between the two adjacent carriers 10 in the first direction X is more stable, and there is no gap between the two adjacent carriers 10 in the first direction X, and the waterproof effect of the carrier 100 is better.

[0044] See also Figure 2 Furthermore, in some embodiments, in the second direction Y, the carrier 10 includes a third end 17 and a fourth end 19 connected to both the first end 13 and the second end 15, the third end 17 is provided with an opening 171 for inserting the curved photovoltaic component 300, and the fourth end 19 is provided with a mounting hole 191, and the mounting hole 191 is used for connecting the carrier 10 to the roof purlin through an assembly part.

[0045] The opening 171 is used for the curved photovoltaic component 300 to extend into the first groove 11 of the carrier 10. When the curved photovoltaic component 300 is loaded into the carrier 10 from the opening 171, the edge of the curved photovoltaic component 300 abuts against the first end 13, the second end 15 and the fourth end 19 of the carrier 10, so that the curved photovoltaic component 300 can be stably installed in the carrier 10.

[0046] The number of mounting holes 191 may be, but is not limited to, one, two, three or more. When the number of mounting holes 191 is one, the mounting hole 191 may be provided at any position of the fourth end 19 of the carrier 10. When the number of mounting holes 191 is multiple, the multiple mounting holes 191 may be evenly or unevenly distributed at the fourth end 19 of the carrier 10. Preferably, the multiple mounting holes 191 are evenly distributed at the fourth end 19 of the carrier 10, so that when the assembly is connected to the roof purlin, the force at each position of the carrier 10 is more uniform, and the connection between the carrier 10 and the roof purlin is also more stable. The opening shape of the mounting hole 191 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes.

[0047] The assembly parts are connected to the roof purlins, so that the carrier 10 is firmly mounted on the roof purlins. The assembly parts can be a structure of bolts and nuts, the bolts pass through the mounting holes 191 and the roof purlins, and the nuts cooperate with the bolts to tightly connect the carrier 10 and the roof purlins. The tight connection between the assembly parts and the roof purlins can prevent the carrier 10 from shaking relative to the roof purlins, thereby causing safety accidents. The number of assembly parts is the same as the number of mounting holes 191. For example, when there is one mounting hole 191, there is also one assembly part. At this time, the material used for the assembly parts is less, which can save materials. When there are four mounting holes 191, there are also four assembly parts. At this time, the connection between the assembly parts and the roof purlins can make the carrier 10 more firmly mounted on the roof purlins.

[0048] See also Figure 3 The curved photovoltaic assembly 1000 of the embodiment of the present application includes the carrier 100 of the above embodiment and a plurality of curved photovoltaic components 300 , the plurality of curved photovoltaic components 300 respectively correspond to a plurality of carriers 10 , and the curved photovoltaic components 300 are installed in the first grooves 11 of the corresponding carriers 10 .

[0049] Among them, the curved photovoltaic module 1000 can be used as a component of a building while converting light energy into electrical energy, and it can also be aesthetically pleasing. Each curved photovoltaic component 300 is installed in a carrier 10, and the carrier 10 can provide good support for the curved photovoltaic component 300. In addition, two adjacent carriers 10 in the first direction X can be connected to each other through the mounting portion 131 and the coupling portion 151, so that in the first direction X, there will be no gaps in the curved photovoltaic module 1000, and rainwater will not enter the interior of the building from the gaps on rainy days, and the curved photovoltaic module 1000 has a good waterproof effect.

[0050] In the curved photovoltaic module 1000 of the embodiment of the present application, the mounting portion 131 of one carrier 10 is combined with the coupling portion 151 of another carrier 10, so that two adjacent carriers 10 are firmly connected in the first direction X. In addition, the mounting portion 131 and the coupling portion 151 are tightly connected, and there is no gap between the two adjacent carriers 10 in the first direction X. Rainwater will not enter the interior of the building through the gap on rainy days, and the waterproof effect of the carrier 100 is better.

[0051] See also Figure 4In some embodiments, the curved photovoltaic device 300 includes a front plate 306, a battery cell 307, a back plate 309, a junction box 305 and a film layer 308, wherein the front plate 306, the film layer 308, the battery cell 307, the film layer 308, the back plate 309 and the junction box 305 are stacked in sequence. Among them, the front plate 306 is a structure for protecting the battery cell 307, and the front plate 306 can be a curved transparent tempered glass. The battery cell 307 is a structure for converting light energy into electrical energy, and the battery cell 307 can be, but is not limited to, a crystalline silicon battery cell 307, a thin film battery cell 307 or a perovskite battery cell 307, etc. The back plate 309 is also a structure for protecting the battery cell 307, and the back plate 309 can be tempered glass, polyethylene terephthalate (PET) or a photovoltaic-grade back plate 309, etc. The material of the photovoltaic-grade backplane 309 includes, but is not limited to, a PET composite material or a glass fiber composite material. The adhesive film layer 308 is used to bond the front plate 306 and the battery cell 307, and to bond the battery cell 307 and the backplane 309. The adhesive film layer 308 can be ethylene vinyl acetate, polyolefin, polyvinyl butyral or organic silica gel.

[0052] The thickness of the front plate 306 may be in the range of [3mm, 5mm]. When the thickness of the front plate 306 is less than 3mm, the strength of the front plate 306 is too low, and the front plate 306 is at risk of breaking in bad weather (such as heavy rain, snow or hail). When the thickness of the front plate 306 is greater than 5mm, the weight of the front plate 306 is heavier, and thus the weight of the curved photovoltaic element 300 is heavier, and the curved photovoltaic element 300 is not easy to transport and handle. When the thickness of the front plate 306 is in the range of [3mm, 5mm], the strength of the front plate 306 is higher, and the front plate 306 will not be at risk of breaking in bad weather. And the weight of the front plate 306 is also lighter, and the curved photovoltaic element 300 is easy to transport and handle. The specific thickness of the front plate 306 may be determined according to the weather conditions in various places. For example, in areas with frequent hail, the thickness of the front plate 306 may be thicker, so that the strength of the front plate 306 is higher. In warm climates and hail-free areas, the thickness of the front plate 306 can be thinner. Both the front plate 306 and the back plate 309 have certain water-blocking and insulation functions. In a high humidity environment, water vapor in the environment will not enter through the front plate 306 or the back plate 309, thereby causing damage to the battery cell 307.

[0053] See also Figures 1 to 3 In some embodiments, the bottom wall 111 of the first groove 11 is a curved surface that matches the curved photovoltaic component 300 , and the curved photovoltaic component 300 is supported on the bottom wall 111 of the first groove 11 .

[0054] Specifically, the longitudinal projection of the curved photovoltaic element 300 is a curve consisting of one or more curved segments. For example, the number of curved segments may be one, two, three, four or more segments. When the curved segment is one segment, the shape of the curved photovoltaic element 300 is an arc-shaped curved surface with a single crest. When the curved segment is multiple segments, the shape of the curved photovoltaic element 300 is a wavy curved surface with multiple crests. The bending radius of each curved segment of the curved photovoltaic element 300 is the same. For example, the bending radius of the curved photovoltaic element 300 may be 25 mm, 50 mm, 100 mm or 200 mm, etc.

[0055] The bottom wall 111 is a structure for supporting the curved photovoltaic element 300. Preferably, the bending radius of the bottom wall 111 is the same as the bending radius of the curved photovoltaic element 300. For example, when the bending radius of the curved photovoltaic element 300 is 100 mm, the bending radius of the bottom wall 111 is also 100 mm. At this time, the curved photovoltaic element 300 can be completely fitted with the bottom wall 111, and the bottom wall 111 can support all positions of the curved photovoltaic element 300. When the curved photovoltaic element 300 is directly supported on the roof purlin, the roof purlin can only support part of the structure of the curved photovoltaic element 300. Due to the gravity of the curved photovoltaic element 300 itself, when the curved photovoltaic element 300 is supported on the roof purlin for a long time, the curved photovoltaic element 300 may be deformed or even broken. The curved photovoltaic component 300 of the present application is carried on the bottom wall 111 of the carrier 10, and the bottom wall 111 can provide uniform support for each position of the curved photovoltaic component 300, so that the curved photovoltaic component 300 will not be deformed or broken. And because the bottom wall 111 can provide uniform support for each position of the curved photovoltaic component 300, the thickness of the curved photovoltaic component 300 can be thinner. At this time, the curved photovoltaic component 300 can save materials, and the curved photovoltaic component 300 is also more convenient to carry and place.

[0056] See also Figures 2 to 4 In some embodiments, the curved photovoltaic device 300 includes a light-receiving surface 301 and a backlight surface 303 opposite to each other, and a junction box 305 is disposed on the backlight surface 303. The junction box 305 is used to transmit electrical signals of the curved photovoltaic device 300. The bottom wall 111 of the first groove 11 of the carrier 10 is provided with a second groove 1111, and the second groove 1111 is used to accommodate the junction box 305.

[0057] The junction box 305 can be used to output electrical signals such as current, voltage and power of the curved photovoltaic element 300. A conductive member 3051 is provided on the junction box 305. The conductive member 3051 of one curved photovoltaic element 300 is used to electrically connect with another curved photovoltaic element 300, so that multiple curved photovoltaic elements 300 are connected in series and / or in parallel. The conductive member 3051 can be, but is not limited to, a wire, a circuit board or a flexible circuit board, etc. The conductive member 3051 of the present application is a wire.

[0058] The second groove 1111 is connected to the first groove 11. The junction box 305 protrudes from the backlight surface 303 of the curved photovoltaic component 300. When the curved photovoltaic component 300 is installed in the first groove 11, the junction box 305 extends into the second groove 1111. The opening area of ​​the second groove 1111 is at least larger than the area of ​​the junction box 305, so that the junction box 305 can be smoothly accommodated in the second groove 1111. The opening shape of the second groove 1111 can be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygons. When the junction box 305 is accommodated in the second groove 1111, the backlight surface 303 of the curved photovoltaic component 300 can fit with the bottom wall 111, so that the bottom wall 111 can play a better supporting role for the curved photovoltaic component 300.

[0059] See also Figures 2 to 4 Furthermore, in some embodiments, the bottom wall 111 of the first groove 11 is also provided with a third groove 1113, and the conductive member 3051 is accommodated in the third groove 1113. Among them, the third groove 1113 is a spatial structure for accommodating the conductive member 3051 extending from the junction box 305. When the conductive member 3051 is accommodated in the third groove 1113, the conductive member 3051 will not occupy extra space, so that the structure of the curved photovoltaic module 1000 is more compact. Since each curved photovoltaic component 300 is provided with a conductive member 3051, if the conductive member 3051 is placed randomly, it will appear messy. The conductive members 3051 of the present application are all placed in the third groove 1113, the conductive member 3051 will not be too messy, and the overall appearance of the curved photovoltaic module 1000 is more beautiful.

[0060] And the third groove 1113 is located close to the fourth end 19 of the carrier 10. In the second direction Y, the first end 13 of the upper carrier 10 overlaps the fourth end 19 of the lower carrier 10, so that the third groove 1113 and the conductive member 3051 of the lower carrier 10 are shielded by the upper carrier 10. When the conductive member 3051 is shielded, the conductive member 3051 will not be directly exposed to sunlight, and the service life of the conductive member 3051 is longer. And rainwater will not directly flow into the vicinity of the conductive member 3051, and the overall safety of the curved photovoltaic module 1000 is better.

[0061] See also Figure 5The photovoltaic building surface 10000 of the embodiment of the present application includes the curved photovoltaic component 1000 of the above embodiment.

[0062] In the photovoltaic building surface 10000 of the embodiment of the present application, the mounting portion 131 of one carrier 10 is combined with the coupling portion 151 of another carrier 10, so that the two adjacent carriers 10 in the first direction X are firmly connected. In addition, the mounting portion 131 and the coupling portion 151 are tightly connected, and there is no gap between the two adjacent carriers 10 in the first direction X. Rainwater will not enter the interior of the building through the gap on rainy days, and the waterproof effect of the carrier 100 is better.
