The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] Please refer to Figure 1 and Figure 2 The photovoltaic module in the utility model, including transparent pipe fitting 10 and battery piece 20 fixed in the transparent pipe fitting 10, the light receiving surface of the battery piece 20 is arranged towards the radial direction of the transparent pipe fitting 10, both ends of the transparent pipe fitting 10 are respectively provided with sealing cover 30, the sealing cover 30 is provided with air cock (not shown in the drawing), and the air cock is used to fill inert gas into the transparent pipe fitting.

[0030] By combining the transparent pipe 10 with the inert gas to encapsulate the battery piece 20, the photovoltaic module is extremely light, which is convenient for installation on the building facade or the roof with low bearing capacity. Secondly, the design of the transparent pipe 10 supports the best inclination of the battery piece 20 for flat installation, which does not depend on the photovoltaic support. The inclination of the battery piece 20 can be adjusted by adjusting the rotation angle of the transparent pipe 10, which simplifies the installation process and reduces the system cost.

[0031] In the embodiment, the battery piece 20 includes but is not limited to a polycrystalline silicon battery piece 20, and can also be a monocrystalline silicon battery piece, a perovskite battery, various laminated or organic solar cells, etc. The embodiment is only an example and is not limited.

[0032] It should be noted that the inert gas filled in the transparent pipe 10 in the embodiment is nitrogen or argon, which ensures the long-term stability of the battery piece 20 and avoids the reduction of power generation efficiency caused by oxidation, attenuation or micro-cracks.

[0033] Further, the surface of the sealing cover 30 is provided with a scale line, the surface of the transparent pipe 10 is provided with a pointer pointing to the scale line, and the pointer is aligned with the edge of the battery piece 20. In actual application, when the transparent pipe 10 is assembled, the transparent pipe 10 can be rotated to keep the plane of the battery piece 20 consistent with the corresponding scale line, so that the photovoltaic module with the best installation inclination according to the geographical latitude of the specified location can be produced, so that the photovoltaic module can obtain the maximum power generation.

[0034] For example, in the embodiment, the cross section of the transparent pipe 10 is circular, and the following embodiments are further described based on the circular transparent pipe 10, but do not constitute a limitation on the structure of the transparent pipe 10. The cross section of the transparent pipe 10 can also be oval, hexagonal, etc., and the diameter, material, thickness, etc. can be adjusted according to the actual application scene.

[0035] Specifically, in the embodiment, there are many ways to fix the battery piece 20 in the transparent pipe 10, and the following four embodiments are described as examples.

[0036] First embodiment

[0037] Referring to Figure 2 , the transparent pipe 10 includes a pipe body 11 and a supporting plate 12 integrally formed in the pipe body 11. The mounting surface of the supporting plate 12 is arranged in the radial direction of the pipe body 11, and the battery piece 20 is fixed to the mounting surface of the supporting plate 12 by an adhesive structure 21.

[0038] Specifically, the adhesive structure 21 includes but is not limited to resin, and can also be silicone, acrylic, EVA or POE material, etc.

[0039] Further, the inner shell of the sticky structure 21 incorporates a certain proportion of yttrium oxide (YO) doped with erbium (Er 3 +)** and** ytterbium (Yb 3 +), preferably in a proportion of 0.1%-0.5%; infrared light can be converted into green light to reduce the working temperature of the battery sheet 20 and improve the photoelectric conversion efficiency.

[0040] Second embodiment

[0041] Referring to Figure 3 , the transparent pipe 10 comprises a pipe body 11 and a supporting plate 12, the inner wall of the pipe body 11 is provided with two opposite clamping groove structures 13, the supporting plate 12 is clamped and fixed in the pipe body 11 through the clamping groove structure 13, and the battery sheet 20 is fixed on the surface of the supporting plate 12 through the sticky structure 21.

[0042] It can be seen that the improvement of the present embodiment compared with the first embodiment is that the supporting plate 12 can be detachably arranged in the pipe body 11, so that the battery sheet 20 arranged on the supporting plate 12 can be extracted together with the supporting plate 12, facilitating subsequent maintenance and repair. The sticky structure 21 in this embodiment is the same as the sticky structure 21 in the first embodiment, and thus will not be described again.

[0043] Third embodiment

[0044] Referring to Figure 4 , the transparent pipe 10 comprises a pipe body 11 and a bracket 40, the bracket 40 has an arc-shaped plate 41 arranged in close contact with the inner wall of the pipe body 11, and a horizontal plate 42 connecting two ends of the arc-shaped plate 41, and the battery sheet 20 is fixed on the horizontal plate 42 through the sticky structure 21.

[0045] Specifically, in the present embodiment, since the cross section of the transparent pipe 10 is circular, the horizontal plate 42 combined with the arc-shaped plate 41 forms a pipe body 11 with a semicircular cross section, which is fixed in the pipe body 11 by three points, i.e. the end points of the two ends of the horizontal plate 42 and the apex of the arch of the arc-shaped plate 41. In use, the battery sheet 20 adhered to the bracket 40 can be extracted together with the bracket 40, achieving the same technical effect as the second embodiment. It can be seen that the present embodiment aims to provide another form of detachable assembly of the battery sheet 20.

[0046] It should be noted that in actual application, the cross-sectional shape of the bracket 40 changes according to the cross-sectional shape of the pipe body 11, that is, when the cross section of the pipe body 11 is circular, the cross section of the bracket 40 is semicircular, when the cross section of the pipe body 11 is elliptical, the cross section of the bracket 40 is semelliptical, and so on, as long as the bracket 40 can be stably fixed in the pipe body 11.

[0047] Similarly, the adhesive structure 21 in this embodiment is the same as the adhesive structure 21 in the first embodiment, and thus will not be described again.

[0048] Fourth embodiment

[0049] Referring to Figure 5 The transparent pipe 10 comprises a pipe body 11 and a transparent air bag assembly, the transparent air bag assembly comprises an upper air bag 51 and a lower air bag 52 arranged in the pipe body 11, the battery sheet 20 is arranged between the upper air bag 51 and the lower air bag 52, and the upper air bag 51 and the lower air bag 52 are inflated to fix the battery sheet 20 in the pipe body 11.

[0050] Specifically, the upper air bag 51 and the lower air bag 52 in this embodiment can be inflated independently or can be connected to form a whole.

[0051] The installation steps of the battery sheet 20 in this embodiment are as follows: first, the battery sheet 20 is arranged between the upper air bag 51 and the lower air bag 52 which are not inflated, then the three are sent into the pipe body 11 together, and finally the upper air bag 51 and the lower air bag 52 are inflated slowly until the air pressure completely adheres the battery sheet 20 to the inner wall of the pipe body 11, so that the fixing of the battery sheet 20 is realized.

[0052] In addition, it is worth mentioning that the air bag is used to fix the battery sheet 20, which can not only provide stable support, but also can play a buffering role to a certain extent. When the pipe is impacted or vibrated externally, the air bag can absorb part of the energy, so as to protect the battery sheet 20 from being damaged.

[0053] In summary, the photovoltaic module in the above embodiments of the utility model realizes the light weight of the photovoltaic module by packaging the battery sheet 20 through the transparent pipe 10 and the inert gas, which is convenient for installation on the building facade or the roof with low bearing capacity. Secondly, the design of the transparent pipe 10 supports the best inclination of the battery sheet 20 for flat installation, which does not depend on the photovoltaic support, and the inclination of the battery sheet 20 can be adjusted by only adjusting the rotation angle of the transparent pipe 10, which simplifies the installation process and reduces the system cost.

[0054] Fifth embodiment

[0055] Please refer to Figure 6 The photovoltaic array comprises a plurality of photovoltaic modules as described in the above technical solutions, the plurality of photovoltaic modules are arranged in parallel, and the battery sheets 20 of two adjacent photovoltaic modules are electrically connected in series, in parallel or in series-parallel.

[0056] Specifically, two adjacent photovoltaic modules are connected by a connecting mechanism, which is a connecting arm 31 connected between two sealing covers 30, and the connecting arm 31 is integrally formed with the sealing covers 30. The number of sealing covers 30 connected in series with the connecting arm 31 can be adjusted according to the number of photovoltaic modules required.

[0057] Further, both ends of the transparent pipe 10 are provided with double-sided blade-type conductive tabs, and the sealing cover 30 is provided with a bidirectional arc-shaped conductive spring that cooperates with the conductive tabs. The bidirectional arc-shaped conductive springs in two adjacent sealing covers 30 are electrically connected by a conductive wire buried in the connecting arm 31. When the transparent pipe 10 cooperates with the connecting sealing cover 30 to form a photovoltaic array, the double-sided blade-type conductive tabs are inserted into the bidirectional arc-shaped conductive springs to realize current convergence of the entire photovoltaic array.

[0058] Further, each sealing cover 30 on the same side of the photovoltaic array is provided with a bypass diode, and the bypass diode is electrically connected to the corresponding photovoltaic module. The bypass diode is arranged in the sealing cover 30, which eliminates the design of the junction box, and when the positive and negative links of an individual photovoltaic module are damaged, the current can be directly connected through the bypass diode without affecting the use of the entire photovoltaic array. In addition, the sealing covers 30 of the two outermost photovoltaic modules are respectively provided with a positive electrode lead-out device 61 and a negative electrode lead-out device 62 for leading out the positive and negative power supply lines of the entire photovoltaic array.

[0059] Further, an infrared generating device is connected in the circuit of the bypass diode. When a photovoltaic module has a problem causing the positive and negative circuits to be disconnected, the current of the entire string will pass through the bypass diode, and the infrared generating device will light up and emit infrared rays. After the maintenance personnel arrive, they can identify which photovoltaic module has been damaged by wearing infrared filter glasses.

[0060] Further, the sealing cover 30 is provided with an inverter module, and the inverter module is connected to the output end of the battery sheet 20 to convert the direct current generated by each battery sheet 20 into alternating current, realizing local power conversion. The inverter module adopts a high-efficiency and small-size design, which is suitable for the limited space in the array connecting mechanism. Through micro-inverter technology, each photovoltaic module not only has power generation function, but also has independent inverter function. It can be understood that compared with the traditional photovoltaic system, each photovoltaic module has its own inverter module, so there is no need for centralized inverters, and the output of each module in the photovoltaic power station is alternating current, avoiding the use of centralized inverters and complex busbar connections, with less conversion loss.

[0061] In the description of the specification, the description of the terms "one embodiment", "some embodiments", "an example", "a specific example", or "some examples" and the like means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present application. In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0062] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
