[0034] As can be seen from the background technology, the development of recycling technology and equipment for photovoltaic modules needs further research.

[0035] After analysis, it was found that there is no targeted recycling plan for damaged and exploded photovoltaic modules. Generally, the damaged and exploded photovoltaic modules are directly dismantled and transported. For photovoltaic modules that have exploded, if they are not protected to a certain extent, they may be damaged again during the dismantling and transportation process, resulting in the scattering of damaged parts of the photovoltaic modules, which in turn affects the soil and other ecological environments at the installation location of the photovoltaic modules.

[0036] The disclosed embodiments provide a carrier for recycling photovoltaic modules and a method for recycling photovoltaic modules. In the carrier, on the one hand, the main body is designed to carry the target photovoltaic module, and the adhesive portion is fixedly connected to the back of the target photovoltaic module. In other words, the adhesive portion fits the back panel of the target photovoltaic module, which is conducive to improving the overall mechanical strength of the back panel of the target photovoltaic module and avoiding secondary breakage of the back panel of the target photovoltaic module, thereby ensuring the integrity of the back panel of the target photovoltaic module during disassembly, and avoiding the scattering of damaged parts on the back panel of the target photovoltaic module, so as to avoid contaminating the soil and other ecological environments at the installation location of the target photovoltaic module. On the other hand, the main body is designed to carry the target photovoltaic module, and the buckle belt is buckled with the fixing belt to jointly surround the front and sides of the target photovoltaic module to achieve bundling of the target photovoltaic module. In other words, the entire carrier holds the target photovoltaic module, which is conducive to all-round protection of the target photovoltaic module during the transportation process, so that no matter whether the back panel or other components of the target photovoltaic module are damaged, the integrity of the target photovoltaic module during the transportation process can be ensured to avoid the scattering of any damaged parts of the target photovoltaic module, and further avoid contaminating the soil and other ecological environments at the installation location of the target photovoltaic module.

[0037] The carrier for recycling photovoltaic components and the method for recycling photovoltaic components provided in the embodiments of the present disclosure are both applied to the National Key R&D Program Project (2022YFB4202103).

[0047] The following will describe the various embodiments of the present disclosure in detail with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that in the various embodiments of the present disclosure, many technical details are provided in order to enable the reader to better understand the embodiments of the present disclosure. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solutions claimed in the embodiments of the present disclosure can be implemented.

[0048] An embodiment of the present disclosure provides a carrier for recycling photovoltaic components. The carrier for recycling photovoltaic components provided by an embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0049] Combined with reference Figures 1 to 3 The carrier 100 for recycling photovoltaic modules comprises: a main body 101 for carrying a target photovoltaic module 200, wherein the target photovoltaic module 200 is a photovoltaic module to be recycled; a plurality of adhesive portions 102, each having a first surface 112 and a second surface 122 arranged opposite to each other along a first direction X, wherein the first surface 112 is fixedly connected to the main body 101, and when the main body 101 carries the target photovoltaic module 200, the second surface 122 of the adhesive portion 102 is used to be fixedly connected to the back surface of the target photovoltaic module 200; and a plurality of fixing straps 102. 03 and a plurality of buckling straps 104, the fixing straps 103 and the buckling straps 104 are respectively fixedly connected to the opposite sides of the main body 101 along the second direction Y, the fixing straps 103 and the buckling straps 104 are opposite to each other along the second direction Y, and the opposite fixing straps 103 and buckling straps 104 are jointly configured that when the main body 101 carries the target photovoltaic component 200, the buckling straps 104 buckle with the fixing straps 103 to jointly surround the front and side surfaces of the target photovoltaic component 200, so as to achieve bundling of the target photovoltaic component 200.

[0050] It should be noted that Figure 1 A schematic top view of a carrier for recycling photovoltaic components provided in one embodiment of the present disclosure; Figure 2 A first partial cross-sectional schematic diagram of a carrier for recycling photovoltaic components provided by an embodiment of the present disclosure; Figure 3 This is a second partial cross-sectional schematic diagram of a carrier for recycling photovoltaic modules provided in an embodiment of the present disclosure. In addition, in order to reflect the positional relationship between the fixing belt 103 and the buckle belt 104 and the main body 101, Figure 1 The main body 101 is drawn in perspective.

[0051] It is worth noting that Figure 1 It is a top view schematic diagram when the carrier is not tied to the target photovoltaic module.

[0052] In some cases, the photovoltaic modules to be recycled, i.e., the target photovoltaic modules 200, may be photovoltaic modules whose service life has expired, or photovoltaic modules that have been damaged or exploded. Among the photovoltaic modules that have been damaged or exploded, the back and front of the photovoltaic modules located at the outermost part are most likely to be damaged or exploded, for example, there may be cracks on the back plate constituting the back of the photovoltaic module or the cover plate constituting the front of the photovoltaic module.

[0053] In one example, the material of the back plate constituting the back of the photovoltaic module may be glass. It should be noted that the specific composition of the target photovoltaic module 200 will be described in detail later, and will not be repeated here.

[0054] In view of the target photovoltaic module 200, an embodiment of the present disclosure specifically designs a carrier 100 for recycling the target photovoltaic module 200. On the one hand, the main body 101 is designed to carry the target photovoltaic module 200, and the second surface 122 of the adhesive portion 102 is fixedly connected to the back of the target photovoltaic module 200. In other words, the second surface 122 of the adhesive portion 102 fits the back plate of the target photovoltaic module 200, and multiple fixed points are set on the back plate of the target photovoltaic module 200 with the help of the adhesive portion 102, which is conducive to improving the overall mechanical strength of the back plate of the target photovoltaic module 200, avoiding secondary breakage of the back plate of the target photovoltaic module 200, thereby ensuring the integrity of the back plate of the target photovoltaic module 200 when disassembling, and avoiding the scattering of damaged parts on the back plate of the target photovoltaic module 200, so as to avoid polluting the soil and other ecological environment at the installation location of the target photovoltaic module 200.

[0055] On the other hand, the main body 101 is designed to carry the target photovoltaic assembly 200, and the buckle belt 104 is buckled with the fixing belt 103 to jointly surround the front and side of the target photovoltaic assembly 200 to achieve the bundling of the target photovoltaic assembly 200. In other words, the entire carrier 100 holds the target photovoltaic assembly 200, which is conducive to the overall protection of the target photovoltaic assembly 200 by the main body 101, the buckle belt 104 and the fixing belt 103 during the transportation of the target photovoltaic assembly 200, so that when the back panel or other components of the target photovoltaic assembly 200 are damaged, the integrity of the target photovoltaic assembly 200 during the transportation process can be ensured to avoid the scattering of any damaged parts of the target photovoltaic assembly 200, and further avoid polluting the soil and other ecological environment at the installation location of the target photovoltaic assembly 200.

[0056] The carrier provided in one embodiment of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0057] In some embodiments, continue to refer to Figures 1 to 3 The melting temperature of the adhesive portion 102 is lower than the melting temperature of the main body 101. The adhesive portion 102 is configured to be bonded to the back side of the target photovoltaic component 200 after being melted by heat, and the adhesive portion 102 can be solidified as the temperature decreases to achieve a fixed connection with the back side of the target photovoltaic component 200.

[0058] It is worth noting that the main body 101 in the carrier 100 is mainly used to carry the target photovoltaic module 200 and provide the first level of support and protection for the target photovoltaic module 200. Based on this, when the main body 101 carries the target photovoltaic module 200, the adhesive part 102 is melted by heat and adheres to the back of the target photovoltaic module 200, which is conducive to bonding the back plate of the target photovoltaic module 200 as a whole to ensure the integrity of the back plate of the target photovoltaic module 200, and further, the adhesive part 102 can be solidified as the temperature decreases to achieve a fixed connection with the back of the target photovoltaic module 200, which is conducive to improving the overall mechanical strength of the back plate of the target photovoltaic module 200 and providing the second level of support and protection for the target photovoltaic module 200. In addition, the melting temperature of the adhesive part 102 is lower than the melting temperature of the main body 101, which is conducive to ensuring that when the adhesive part 102 is melted by heat, the first level of support and protection of the target photovoltaic module 200 by the main body 101 continues to exist.

[0059] Moreover, based on the characteristics of the adhesive portion 102 melting by heat and solidifying by cooling, the adhesive portion 102 can be repeatedly heated and cooled to achieve bonding and further fixed connection with the back panels of multiple target photovoltaic modules 200 in turn. In other words, the carrier 100 can be reused in the process where the target photovoltaic modules 200 need to be transported, that is, the versatility of the carrier 100 is improved. Specifically, after the adhesive portion 102 is melted by heat for the first time and solidified by cooling, the carrier 100 supports, protects and binds a certain target photovoltaic module 200. After the target photovoltaic module 200 is transported to the destination, the adhesive portion 102 can be heated again to melt the adhesive portion 102 again, so that the adhesive portion 102 can be detached from the back panel of the target photovoltaic module 200, so that the adhesive portion 102 can be fixedly connected to the back of another target photovoltaic module 200 later, so that the carrier 100 can be used repeatedly.

[0060] It should be noted that the specific situation in which the adhesive portion 102 is melted by heat will be described below with examples, which will not be elaborated here.

[0061] In some embodiments, in conjunction with reference Figures 4 to 6 The main body 101 may include a rough area 141 in contact with the adhesive part 102, the rough area 141 has a plurality of protrusions 141a and a plurality of grooves 141b, and the adhesive part 102 covers the protrusions 141a and is embedded in the grooves 141b.

[0062] In this way, based on the protrusions 141a and grooves 141b on the rough area 141, the surface where the main body 101 contacts the adhesive portion 102, that is, the rough area 141 is a rough surface, which is beneficial to increase the contact area between the main body 101 and the adhesive portion 102, and increase the friction between the main body 101 and the adhesive portion 102, thereby ensuring that the connection strength between the adhesive portion 102 and the main body 101 is greater than the connection strength between the adhesive portion 102 and the back panel of the target photovoltaic module 200, so as to ensure the integrity of the carrier 100.

[0063] It should be noted that Figure 4 A first schematic top view of the main body of a carrier for recycling photovoltaic components provided in an embodiment of the present disclosure; Figure 5 for Figure 4 A partial enlarged cross-sectional schematic diagram of the main body shown; Figure 6 A partially enlarged cross-sectional schematic diagram of a carrier for recycling photovoltaic modules provided in one embodiment of the present disclosure. In addition, Figure 4 The rough area 141 is indicated by a dotted line frame, and the protrusions and grooves are indicated by a dotted line frame.

[0064] In some cases, based on the characteristics of the adhesive portion 102 melting under heat and solidifying under temperature, the carrier 100 can be used repeatedly. Based on this, the main body 101 is designed to include a rough area 141 in contact with the adhesive portion 102. With the design of the rough area 141, the contact area between the main body 101 and the adhesive portion 102 is increased, and the friction between the main body 101 and the adhesive portion 102 is increased to ensure that the connection strength between the adhesive portion 102 and the main body 101 is greater than the connection strength between the adhesive portion 102 and the back plate of the target photovoltaic module 200, so as to ensure that when the adhesive portion 102 that has been fixedly connected to the back of the target photovoltaic module 200 is heated and melted again, the adhesive portion 102 is detached from the back plate of the target photovoltaic module 200 to ensure the integrity of the carrier 100.

[0065] In some embodiments, the material of the adhesive portion 102 may include at least one of EVA hot melt adhesive, thermoplastic resin adhesive, thermoplastic copolyester adhesive, or thermoplastic polyurethane.

[0066] In some embodiments, the material of the main body may include plastic materials such as PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), and PVC (polyvinyl chloride).

[0067] In some embodiments, the thickness of the adhesive portion 102 in the first direction X is 0.5 mm to 10 mm. For example, the thickness of the adhesive portion 102 in the first direction X may be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, or 9 mm.

[0068] In some embodiments, the thickness of the main body 101 in the first direction X is 0.3 mm to 25 mm. For example, the thickness of the main body 101 in the first direction X can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, 18 mm, 20 mm or 23 mm, etc.

[0069] In some embodiments, the orthographic projection shape of the adhesive portion 102 on the main body 101 may be a rectangle.

[0070] In some examples, the length of the adhesive portion 102 in the second direction Y can be 150mm to 220mm, for example, the length of the adhesive portion 102 can be 155mm, 160mm, 165mm, 170mm, 175mm, 180mm, 185mm, 190mm, 195mm, 200mm, 210mm or 215mm, etc.; the width of the adhesive portion 102 in the third direction Z can be 20mm to 100mm, for example, the width of the adhesive portion 102 can be 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm or 95mm, etc.

[0071] In some embodiments, the cell string in the target photovoltaic module 200 is formed by electrically connecting a plurality of half-cell photovoltaic cells, and the ratio of the orthographic projection area of ​​the adhesive portion 102 on the main body 101 to the orthographic projection area of ​​the half-cell photovoltaic cell on the main body 101 is greater than 10%. In some examples, the orthographic projection of the adhesive portion 102 on the main body 101 may also be located in the orthographic projection of the half-cell photovoltaic cell on the main body 101. In this way, it is helpful to ensure that a single adhesive portion 102 has sufficient contact area with the back plate of the target photovoltaic module 200, so as to ensure a high connection strength between the adhesive portion 102 and the back plate of the target photovoltaic module 200.

[0072] In some embodiments, in conjunction with reference Figures 7 to 10 The main body 101 may have a hollow groove 111, and the hollow groove 111 is configured to accommodate the wire box 204 or the cable (not shown in the figure) in the target photovoltaic component 200 when the main body 101 carries the target photovoltaic component 200.

[0073] In this way, on the one hand, when the main body 101 carries the target photovoltaic component 200, the wire box 204 or cable in the target photovoltaic component 200 can be embedded in the hollow groove 111, that is, with the help of the mutual limitation of the wire box 204 or the cable and the hollow groove 111, the main body 101 and the target photovoltaic component 200 can be aligned to improve the portability of the carrier 100 carrying the target photovoltaic component 200; on the other hand, designing the hollow groove 111 on the main body 101 to accommodate the wire box 204 or cable in the target photovoltaic component 200 is conducive to ensuring the normal connection and normal operation of the wire box 204 or cable in the target photovoltaic component 200; on the other hand, designing the hollow groove 111 on the main body 101 is conducive to reducing the material cost of the main body 101, so as to reduce the preparation cost of the carrier 100.

[0074] In some embodiments, in conjunction with reference Figures 7 to 10The carrier 100 may further include: a plurality of shielding portions 105, any shielding portion 105 being fixedly connected to the middle portion of the fixing belt 103 or the buckling belt 104, and the shielding portion 105 and the adhesive portion 102 correspond one to one; wherein, when the main body 101 carries the target photovoltaic component 200, the shielding portion 105 is located on the front side of the target photovoltaic component 200, and the plane perpendicular to the first direction X is taken as the reference plane, and the orthographic projection of the adhesive portion 102 on the reference plane is located in the orthographic projection of the shielding portion 105 on the reference plane.

[0075] It should be noted that Figure 7 Another schematic top view of a carrier for recycling photovoltaic components provided by an embodiment of the present disclosure; Figure 8 A bottom-up schematic diagram of a target photovoltaic assembly provided by an embodiment of the present disclosure; Fig. 9 A bottom-up schematic diagram of a target photovoltaic component carried on a carrier for recycling photovoltaic components provided by an embodiment of the present disclosure; Fig.10 A schematic top view of a target photovoltaic module carried on a carrier for recycling photovoltaic modules provided in an embodiment of the present disclosure. In addition, the carrier 100 further includes a shielding portion 105, taking the main body 101 including the hollow groove 111 as an example, and will be described in detail in the following. In practical applications, such as Figure 1 In the embodiment corresponding to the main body 101 not including the hollow groove, the carrier 100 may also include a shielding portion 105 .

[0076] It is worth noting that when the main body 101 carries the target photovoltaic component 200, the orthographic projection of the adhesive part 102 on the reference surface is designed to be located in the orthographic projection of the shielding part 105 on the reference surface, which is conducive to ensuring that the shielding part 105 completely shields the adhesive part 102. In this way, when the adhesive part 102 is melted by the local hot spot effect of the target photovoltaic component 200 caused by the shielding part 105, it is conducive to controlling the heat generated by the local hot spot effect caused by the shielding part 105 to be concentrated at the contact point between the adhesive part 102 and the target photovoltaic component 200. In other words, the targeted heating of the adhesive part 102 by the shielding part 105 is not only conducive to heating the adhesive part 102 by the characteristics of the target photovoltaic component 200 itself, but also conducive to ensuring that the light spot effect generated by the target photovoltaic component 200 has a good heating effect on the adhesive part 102.

[0077] In addition, part of the shielding portion 105 is designed on the middle part of the fixing belt 103, and the remaining shielding portion 105 is designed on the middle part of the buckling belt 104. With the help of the fixing belt 103 and the buckling belt 104 surrounding the front and side of the target photovoltaic component 200, when the carrier 100 realizes the bundling of the target photovoltaic component 200, the shielding portion 105 is located on the front of the target photovoltaic component 200 as the fixing belt 103 and the buckling belt 104 surround, so as to achieve shielding of the front of the target photovoltaic component 200, so that when the target photovoltaic component 200 is in a working state, the part of the target photovoltaic component 200 that is opposite to the shielding portion 105 will produce a hot spot effect, thereby causing the adhesive portion 102 to melt due to the heat.

[0078] It should be noted that the orthographic projection of the adhesive portion 102 on the reference surface is located in the orthographic projection of the shielding portion 105 on the reference surface, which includes at least the following two situations: In some cases, the reference Figures 7 to 10 , the orthographic projection area of ​​the adhesive portion 102 on the reference surface may be smaller than the orthographic projection area of ​​the shielding portion 105 on the reference surface; in other cases, the orthographic projection area of ​​the adhesive portion on the reference surface may also be equal to the orthographic projection area of ​​the shielding portion on the reference surface.

[0079] In some cases, reference Figures 7 to 10 The fixing tape 103 and the buckling tape 104 are respectively fixedly connected to the opposite sides of the main body 101 along the second direction Y, and the multiple adhesive parts 102 are also respectively fixedly connected to the opposite sides of the main body 101 along the second direction Y, and the corresponding adhesive parts 102 close to the fixing tape 103 and the orthographic projections of the shielding parts 105 located on the fixing tape 103 on the reference plane are arranged at intervals along the second direction Y, and the corresponding adhesive parts 102 close to the buckling tape 104 and the orthographic projections of the shielding parts 105 located on the buckling tape 104 on the reference plane are arranged at intervals along the second direction Y, so as to ensure that when the main body 101 carries the target photovoltaic component 200, the orthographic projection of the adhesive part 102 on the reference plane is designed to be located in the orthographic projection of the shielding part 105 on the reference plane.

[0080] In some examples, continue to refer to Figures 7 to 10 In the carrier 100, two adhesive portions 102 are arranged at intervals along the second direction Y, and four adhesive portions 102 are arranged at intervals along the third direction Z. In other words, the plurality of adhesive portions 102 are arranged in an array along the second direction Y and the third direction Z. Based on this, four fixing belts 103 are arranged at intervals along the third direction Z, and each fixing belt 103 is fixedly connected with a shielding portion 105, and the partial shielding portion 105 corresponds to the adhesive portion 102 near the fixing belt 103; four buckle belts 104 are arranged at intervals along the third direction Z, and each buckle belt 104 is fixedly connected with a shielding portion 105, and the partial shielding portion 105 corresponds to the adhesive portion 102 near the buckle belt 104.

[0081] It should be noted that Figure 7 , Fig. 9 and Fig.10 In the figure, only the carrier 100 is taken as an example in which two adhesive portions 102 are arranged at intervals along the second direction Y and four adhesive portions 102 are arranged at intervals along the third direction Z. In actual applications, there is no restriction on the number of adhesive portions arranged at intervals along the second direction, and there is no restriction on the number of adhesive portions arranged at intervals along the third direction. Both can be flexibly selected according to actual needs. Based on this, the number of shielding portions fixedly connected on a fixing belt and the number of shielding portions fixedly connected on a buckling belt can also be flexibly selected.

[0082] It is worth noting that the number of fixing tapes arranged at intervals along the third direction is the same as the number of adhesive portions arranged at intervals along the third direction, and the number of buckling tapes arranged at intervals along the third direction is also the same as the number of adhesive portions arranged at intervals along the third direction, so as to ensure that when the fixing tapes and the buckling tapes are buckled one by one, each fixing tape and each buckling tape can be directly opposite to at least one adhesive portion along the first direction, that is, each fixing tape and each buckling tape can overlap with the positive projection of at least one adhesive portion on the reference surface, so as to facilitate the design of a shielding portion on each fixing tape and each buckling tape that shields the adhesive portion along the first direction. In addition, the number of shielding portions fixedly connected to a fixing tape and a buckling tape that are buckled correspondingly is the same as the number of adhesive portions arranged at intervals along the second direction, so as to ensure that each adhesive portion has a corresponding shielding portion, and it is worth noting that the number of shielding portions respectively connected to a fixing tape and a buckling tape that are buckled correspondingly can be the same or different.

[0083] For example, in other examples, three adhesive portions are arranged at intervals along the second direction, and a corresponding buckled fixing belt is fixedly connected with a shielding portion for shielding one of the three adhesive portions close to the fixing belt, and a buckled belt is fixedly connected with two shielding portions for shielding two of the three adhesive portions close to the buckled belt; or, a corresponding buckled fixing belt is fixedly connected with two shielding portions for shielding two of the three adhesive portions close to the fixing belt, and a buckled belt is fixedly connected with a shielding portion for shielding one of the three adhesive portions close to the buckled belt.

[0084] In some other examples, four adhesive portions are arranged at intervals along the second direction, and two shielding portions are fixedly connected to a corresponding fastening fixing tape for shielding two of the four adhesive portions close to the fixing tape, and two shielding portions are fixedly connected to a fastening tape for shielding two of the four adhesive portions close to the fastening tape; or, one shielding portion is fixedly connected to a corresponding fastening fixing tape for shielding one of the four adhesive portions close to the fixing tape, and three shielding portions are fixedly connected to a fastening tape for shielding three of the four adhesive portions close to the fastening tape; or, three shielding portions are fixedly connected to a corresponding fastening fixing tape for shielding four of the four adhesive portions close to the fixing tape, and one shielding portion is fixedly connected to a fastening tape for shielding one of the four adhesive portions close to the fastening tape.

[0085] The following describes in detail how the adhesive portion 102 is melted by heat.

[0086] In some cases, the adhesive portion 102 can be configured such that when the main body 101 carries the target photovoltaic component 200 and the target photovoltaic component 200 is in a normal working state, the adhesive portion 102 is heated and melted based on the local hot spot effect of the target photovoltaic component 200 caused by the shielding portion 105, so as to be bonded to the back side of the target photovoltaic component 200, and the adhesive portion 102 is cooled and solidified as the local hot spot effect disappears, so as to be fixedly connected to the back side of the target photovoltaic component 200. In this way, when the target photovoltaic component 200 can be in a normal working state, the power of the target photovoltaic component 200 is turned on, and the adhesive portion 102 can be bonded to the back side of the target photovoltaic component 200 with the help of the local hot spot effect generated by the shielding portion 105 of the target photovoltaic component 200. Then, the power of the target photovoltaic component 200 is cut off, and the adhesive portion 102 is cooled and solidified as the local hot spot effect disappears, so as to be fixedly connected to the back side of the target photovoltaic component 200, thereby helping to improve the portability of the carrier 100 for fixing the target photovoltaic component 200.

[0087] In other cases, the adhesive portion 102 can also be configured to melt due to the heating of the heating device so as to adhere to the back side of the target photovoltaic component 200, and the adhesive portion 102 cools down and solidifies when the heating device stops heating so as to be fixedly connected to the back side of the target photovoltaic component 200.

[0088] It is worth noting that the target photovoltaic module 200 is a photovoltaic module that needs to be recycled, so the target photovoltaic module 200 may not work properly due to expiration of its service life or serious damage. Based on this, the adhesive portion 102 is heated by means of a heating device to achieve adhesion between the adhesive portion 102 and the back of the target photovoltaic module 200. In this way, regardless of whether the target photovoltaic module 200 can work normally, it can be ensured that the adhesive portion 102 is melted by heat to be bonded to the back of the target photovoltaic module 200, and the adhesive portion 102 is cooled and solidified to be fixedly connected to the back of the target photovoltaic module 200.

[0089] In some examples, the heating device may be a hot air gun, so as to heat only the adhesive portion 102 intensively, thereby preventing other portions of the main body 101 that are not in contact with the adhesive portion 102 from being significantly affected by high temperature.

[0090] In some embodiments, reference Figure 1 or Figure 7 The fixing belt 103 may include a first end and a second end relative to each other, and a first middle portion connecting the first end and the second end; the buckling belt 104 may include a binding belt 114 and a buckling portion 124, the binding belt 114 includes a third end and a fourth end relative to each other, and a second middle portion connecting the third end and the fourth end, and the fourth end is provided with a buckling portion 124; wherein the first end and the third end are respectively fixedly connected to the two opposite sides of the main body 101 along the second direction Y, and the second end and the fourth end can be fixedly connected with the aid of the buckling portion 124; any shielding portion 105 is fixedly connected to the first middle portion or the second middle portion, and the entire shielding portion 105 is located on a half-cell photovoltaic cell in the target photovoltaic assembly 200.

[0091] It is worth noting that the entire shielding portion 105 is designed to be located on the half-cell photovoltaic cell in the target photovoltaic component 200. In other words, the orthographic projection of the shielding portion 105 on the reference plane is located in the orthographic projection of the half-cell photovoltaic cell on the reference plane. This is beneficial for avoiding the shielding portion 105 from being located in the gap between two adjacent half-cell photovoltaic cells when the fastening tape 104 is fastened to the fixing tape 103 to jointly surround the front and side surfaces of the target photovoltaic component 200, thereby ensuring that the shielding portion 105 has a good shielding effect on the half-cell photovoltaic cell, thereby facilitating improving the heating effect of the adhesive portion 102 of the target photovoltaic component 200 based on the local spot effect generated by the shielding portion 105.

[0092] It should be noted that, in actual applications, the cell string in the target photovoltaic module can also be composed of multiple whole cell sheets electrically connected. Based on this, the entire shielding portion is designed on the whole cell sheet, that is, the orthographic projection of the shielding portion on the reference plane is located in the orthographic projection of the whole cell sheet on the reference plane.

[0093] In addition, an embodiment of the present disclosure does not impose any restrictions on the fixed connection method between the shielding portion 105 and the first middle portion or the second middle portion, and does not impose any restrictions on the specific structure of the buckle portion 124, which only needs to satisfy the buckle function.

[0094] In some examples, a plane perpendicular to the first direction X is used as a reference plane, the orthographic projection area of ​​the shielding portion 105 on the reference plane is a first area, the orthographic projection area of ​​the half-sheet photovoltaic cell on the reference plane is a second area, and the ratio of the first area to the second area is greater than 10%. In this way, under the premise of using the shielding portion 105 to shield the adhesive portion 102, the shielding area of ​​the shielding portion 105 on the half-sheet photovoltaic cell is increased to increase the area of ​​the target photovoltaic module 200 where the light spot effect is generated based on the shielding portion 105, thereby facilitating the improvement of the heating effect on the adhesive portion 102 and ensuring a high bonding strength between the adhesive portion 102 and the back plate of the target photovoltaic module 200.

[0095] In some embodiments, the orthographic projection shape of the shielding portion 105 on the reference surface may be the same as the orthographic projection shape of the adhesive portion 102 on the reference surface. For example, the orthographic projection shapes of the shielding portion 105 and the adhesive portion 102 on the reference surface may both be rectangular.

[0096] In some examples, the length of the shielding portion 105 in the second direction Y may be 150 mm to 220 mm, for example, the length of the shielding portion 105 may be 155 mm, 160 mm, 165 mm, 170 mm, 175 mm, 180 mm, 185 mm, 190 mm, 195 mm, 200 mm, 210 mm or 215 mm, etc.; the width of the shielding portion 105 in the third direction Z may be 20 mm to 100 mm, for example, the width of the shielding portion 105 may be 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm or 95 mm, etc.

[0097] In some embodiments, in conjunction with reference Figures 8 to 15 The target photovoltaic component 200 that the main body 101 needs to carry includes a laminate 202 and a frame 203 that clamps the laminate 202. The back side of the target photovoltaic component 200 is the surface of the back plate 212 in the laminate 202 away from the battery string. The frame 203 includes a clamping portion 213 that clamps the laminate 202 and a bottom supporting portion 223 that is in contact with and connected to the clamping portion 213; wherein, along the first direction X, the spacing between the bottom supporting portion 223 and the back plate 212 is a first spacing D1, the thickness of the whole formed by the main body 101 and the adhesive portion 102 is a first thickness H1, the main body 101 and the adhesive portion 102 are located between the bottom supporting portion 223 and the back plate 212, and the first thickness H1 is greater than or equal to the first spacing D1.

[0098] It should be noted that Fig.11 A cross-sectional schematic diagram of a target photovoltaic component carried on a carrier for recycling photovoltaic components provided by an embodiment of the present disclosure; Fig.12 for Fig.11 A partially enlarged cross-sectional schematic diagram of the target photovoltaic module shown; Fig.13 for Fig.12 A partially enlarged cross-sectional schematic diagram of a target photovoltaic module carried on a carrier for recycling photovoltaic modules is shown; Fig.14 A partial three-dimensional schematic diagram of a target photovoltaic assembly provided by an embodiment of the present disclosure; Fig.15 for Fig.14 A schematic cross-sectional view along the cross-sectional direction MM1.

[0099] In addition, in order to clearly illustrate the positional relationship between the laminate 202 and the frame 203 in the target photovoltaic module 200, Figure 8 and Fig.10 The frame 203 is drawn in perspective; in order to clearly illustrate the positional relationship between the main body 101, the adhesive portion 102, the fixing belt 103 and the buckle belt 104 and the target photovoltaic module 200, Fig. 9 The frame 203 and the main body 101 are drawn in a perspective drawing manner; Figure 8 and Fig. 9 Only the back plate 212 in the laminate is shown. Fig.10 Only the cover plate 222 of the laminate is shown.

[0100] It is worth noting that reference Figures 11 to 13 The frame 203 includes a clamping portion 213 for clamping the laminate 202 and a bottom support portion 223 in contact with the clamping portion 213. The bottom support portion 223 is used to be fixedly connected with other components at the location where the target photovoltaic assembly 200 is installed, so as to achieve the installation and fixation of the target photovoltaic assembly 200. Therefore, the bottom support portion 223 and the back plate 212 generally have a certain distance, that is, a first distance D1, which facilitates the operator to achieve the fixed connection between the bottom support portion 223 and other components at the location where the target photovoltaic assembly 200 is installed. In the process of recovering the target photovoltaic assembly 200, the bottom support portion 223 is detached from the installation position.

[0101] Based on the positional relationship between the bottom support portion 223 and the back plate 212 in the target photovoltaic component 200, the main body 101 and the adhesive portion 102 are arranged between the bottom support portion 223 and the back plate 212, which is not only conducive to ensuring the fit between the adhesive portion 102 and the back plate 212, but also conducive to embedding the carrier 100 into the target photovoltaic component 200, so that the bottom support portion 223 plays a supporting and protective role on the periphery of the main body 101, and avoids the carrier 100 from bundling the target photovoltaic component 200 due to the excessive thickness of the overall structure of the carrier 100 and the target photovoltaic component 200, so as to improve the portability of the operator using the carrier 100 to transport the target photovoltaic component 200.

[0102] In addition, the thickness of the whole formed by the main body 101 and the adhesive part 102, i.e., the first thickness H1, is designed to be greater than or equal to the distance between the bottom support part 223 and the back plate 212, i.e., the first distance D1, which is conducive to avoiding the existence of a gap between the adhesive part 102 and the back plate 212 when the carrier 100 is embedded in the target photovoltaic module 200, and ensuring the close fit between the adhesive part 102 and the back plate 212. Among them, when the first thickness H1 is greater than the first distance D1, it can be regarded that the whole formed by the main body 101 and the adhesive part 102 and the first distance D1 achieve an interference fit.

[0103] In some examples, taking a plane perpendicular to the first direction X as a reference plane, the orthographic projection of the main body 101 on the reference plane is located in the orthographic projection of the outer contour of the frame 203 on the reference plane. For example, the size of the main body 101 is slightly smaller than the size of the outer contour of the frame 203 to ensure that the main body 101 can be embedded between the bottom support portion 223 and the back panel 212, and the bottom support portion 223 supports the main body 101.

[0104] In one example, the width of the outer contour of the frame 203 in the second direction Y may be 1134 mm; the width of the main body 101 in the second direction Y may be 1112 mm to 1131 mm, for example, the width of the main body 101 may be 1115 mm, 1118 mm, 1120 mm, 1124 mm, 1125 mm, 1128 mm or 1130 mm.

[0105] In one example, the length of the outer contour of the frame 203 in the third direction Z can be 2278mm~2382mm, for example, the length of the outer contour of the frame 203 can be 2280mm, 2290mm, 2300mm, 2310mm, 2320mm, 2330mm, 2340mm, 2350mm, 2360mm, 2370mm or 2380mm; the length of the main body 101 in the second direction Y can be 2255mm~2379mm, for example, the length of the main body 101 can be 2260mm, 2280mm, 2300mm, 2340mm, 2350mm, 2360mm or 2370mm.

[0106] In one example, the length of the outer contour of the frame 203 in the third direction Z may be 2278 mm, and the length of the main body 101 in the second direction Y may be 2255 mm-2275 mm, for example, 2253 mm, 2264 mm, 2265 mm, 2268 mm, 2270 mm or 2272 mm; in another example, the length of the outer contour of the frame 203 in the third direction Z may be 2382 mm, and the length of the main body 101 in the second direction Y may be 2359 mm-2379 mm, for example, 2360 mm, 2364 mm, 2365 mm, 2368 mm, 2370 mm, 2372 mm, 2375 mm or 2378 mm.

[0107] The positional relationship between the main body portion 101 and the adhesive portion 102 will be described below with examples.

[0108] In some cases, reference Figure 3 , the adhesive portion 102 is embedded in the main body 101. In this way, not only the first surface 112 of the adhesive portion 102 is fixedly connected to the main body 101, but also the side surface of the adhesive portion 102 is fixedly connected to the main body 101.

[0109] In other cases, reference Figure 2 or Fig.13 , the adhesive portion 102 is located on one side of the main body 101 close to the back plate 212. In this way, only the first surface 112 of the adhesive portion 102 is fixedly connected to the main body 101, and the side surface and the second surface 122 of the adhesive portion 102 are exposed outside the main body 101.

[0110] In some embodiments, in conjunction with reference Figures 9 to 11The surface of the main body 101 away from the back plate 212 includes an edge area 121 abutting against the bottom support portion 223, and a center area 131 surrounded by the edge area 121. The fixing belt 103 and the buckle belt 104 are both fixedly connected to the center area 131, and the fixing belt 103 and the buckle belt 104 are both configured to surround the side of the bottom support portion 223 away from the back plate 212 when the main body 101 carries the target photovoltaic component 200.

[0111] It is worth noting that when the main body 101 can be embedded between the bottom support part 223 and the back plate 212, the bottom support part 223 will abut against the edge area 121 to achieve support for the main body 101. Based on this, the fixing belt 103 and the buckle belt 104 are designed to be fixedly connected to the central area 131 of the main body 101, which is conducive to directly pulling the fixing belt 103 and the buckle belt 104 from the back side of the target photovoltaic module 200 to the front side of the target photovoltaic module 200 while ensuring that the main body 101 can be embedded between the bottom support part 223 and the back plate 212. In other words, the main body 101 is embedded in the target photovoltaic module 200 and the fixing belt 103 and the buckle belt 104 do not interfere with the binding of the target photovoltaic module 200.

[0112] In some cases, the positions where the fixing belt 103 and the buckle belt 104 are fixedly connected to the main body 101, that is, the central area 131 and the adhesive portion 102 are respectively located on two opposite sides of the main body 101 along the first direction X. In other words, the adhesive portion 102 is located on the front side of the main body 101 close to the back plate 212, and the positions where the fixing belt 103 and the buckle belt 104 are fixedly connected to the main body 101 are located on the back side of the main body 101 away from the back plate 212.

[0113] In some embodiments, in conjunction with reference Figure 5 and Figure 6 The main body 101 includes a rough area 141 in contact with the adhesive part 102, and the rough area 141 has a plurality of protrusions 141a and a plurality of grooves 141b. The adhesive part 102 covers the protrusions 141a and is embedded in the grooves 141b.

[0114] It should be noted that, in conjunction with the reference Figure 5 and Fig.11 , the main body 101 is away from the back plate 212 (refer to Fig. 9 ) includes an edge area 121 abutting against the bottom supporting portion 223, and a central area 131 surrounded by the edge area 121, taking a plane perpendicular to the first direction X as a reference plane, the orthographic projection of any rough area 141 on the reference plane may be the edge area 121, may be located in the central area 131, or may be partially located in the edge area 121 and the other part may be located in the central area 131.

[0115] The specific structure of the laminate 202 in the target photovoltaic module 200 is described in detail below.

[0116] In some embodiments, in conjunction with reference Fig.14 and Fig.15 The laminate 202 generally includes a cover plate 222, a packaging film 232, a back plate 212 and a battery string covered by the packaging film 232, which are stacked in sequence. The battery string includes a plurality of battery cells 201 and a plurality of connecting components 252 connecting adjacent battery cells 201. The surface of the battery cell 201 has a plurality of grid lines arranged at intervals. The connecting component 252 is electrically connected to at least one grid line on each of two adjacent battery cells 201 to connect the two adjacent battery cells 201. The battery cells 201 are electrically connected in the form of a whole piece or multiple pieces to form a plurality of battery strings, and the plurality of battery strings are electrically connected in series and / or in parallel.

[0117] In some cases, the battery cell 201 may be a half-cell battery cell, which is a battery formed by a cutting process of a complete battery cell; in other cases, the battery cell 201 may also be a whole battery cell.

[0118] In some embodiments, the cell 201 includes, but is not limited to, one or any combination of PERC cells (Passivated Emitter Rear Cell), IBC cells (Interdigitated Back Contact), TOPCon cells (Tunnel Oxide Passivated Contact), HIT / HJT cells (Heterojunction Technology heterojunction cells), solar thin-film cells, and stacked cells. Among them, solar thin-film cells include, but are not limited to, perovskite solar thin-film cells, copper indium selenide solar thin-film cells, gallium arsenide solar thin-film cells, and cadmium sulfide solar thin-film cells. Stacked cells include, but are not limited to, perovskite cells superimposed on crystalline silicon cells, perovskite cells superimposed on perovskite cells, and perovskite cells superimposed on thin-film cells.

[0119] The cell 201 can be a monocrystalline silicon solar cell, a polycrystalline silicon solar cell, an amorphous silicon solar cell or a multi-compound solar cell, and the multi-compound solar cell can specifically be a cadmium sulfide solar cell, a gallium arsenide solar cell, a copper indium selenide solar cell or a perovskite solar cell. The cell can receive light on both sides or on one side. Taking the case where the cell receives light on one side and the cover plate 222 faces the light-receiving surface of multiple cells in the cell string as an example, the main function of the cover plate 222 is to prevent the cell string from being damaged, to ensure that the target photovoltaic assembly 200 can adapt to the adverse weather environment, and has good photoelectric conversion efficiency. Therefore, the cover plate 222 has high hardness and transparency, wherein the transparency characterizes the transmittance of the cover plate 222 to light of a specific wavelength. Therefore, the cover plate 222 can be a glass cover plate, a plastic cover plate, or the like that has good light transmission function and is not easily damaged.

[0120] At this time, the back plate 212 faces the backlight surface of the battery cell 201, and its main function is to protect the battery cell 201. Therefore, in order to ensure that the back plate 212 has good sealing, insulation, waterproof or aging resistance, the back plate 212 can use a cover plate composed of three layers of polyvinyl fluoride film (PVF) + polyester film (PET) + PVF, referred to as TPT cover plate, in which the outer protective layer PVF has good environmental corrosion resistance, the middle layer PET has good insulation performance, and the inner layer PVF has good bonding performance after surface treatment and packaging film 232. The back plate 212 can also use a cover plate composed of thermoplastic elastomer (TPE) with high elasticity, high strength and recyclability.

[0121] In the case of a double-sided light-receiving cell, the front side of the cell receives incident light and the back side receives reflected light. The main functions of the back plate 212 and the cover plate 222 are to prevent the cell string from being damaged and to ensure that the cell has a good photoelectric conversion efficiency. Therefore, both the back plate 212 and the cover plate 222 can be selected to have good light transmittance and reliability. For example, both the back plate 212 and the cover plate 222 can be set to tempered glass with high transparency and high strength, and two layers of tempered glass are used as the back plate 212 and the cover plate 222 to form a double-glass assembly, thereby further improving the light transmittance and power generation efficiency of the target photovoltaic assembly 200.

[0122] In addition, in order to improve the utilization rate of incident light irradiated on the photovoltaic modules, in the process of preparing the photovoltaic modules, the surface of the back panel 212 and / or the cover panel 222 facing the battery string can be textured in advance, so that the surface of the back panel 212 and / or the cover panel 222 facing the battery string is changed to a concave and convex surface or a velvet surface containing multiple convex structures.

[0123] Since the incident light needs to pass through the packaging film 232 after passing through the cover plate 222 to reach the surface of the battery cell, the packaging film 232 is required to have good transparency. Therefore, the film used in the process of preparing the packaging film 232 can be ethylene-vinyl acetate copolymer (EVA) film, polyethylene octene co-elastomer (POE) film, polyethylene terephthalate (PET) film or polyvinyl butyral film (PVB) film and other films.

[0124] In addition, the adhesive film used in the process of preparing the packaging film 232 can also be an EP film, an EPE film or a PVP film. Among them, the EP film refers to a co-extruded film composed of a stacked EVA film and a POE film, the EPE film refers to a co-extruded film formed by stacking EVA film + POE film + EVA film in sequence, and the PVP film refers to a co-extruded film formed by stacking POE film + EVA film + POE film. The co-extruded film can be prepared by sequentially extruding one or more raw materials onto another film that has been prepared during the film processing process, or bonding different types of films that have been prepared together.

[0125] To sum up, on the one hand, designing the second side 122 of the adhesive portion 102 to fit the back panel of the target photovoltaic component 200 is beneficial to improving the overall mechanical strength of the back panel of the target photovoltaic component 200 and avoiding secondary breakage of the back panel of the target photovoltaic component 200, thereby ensuring the integrity of the back panel of the target photovoltaic component 200 during disassembly, and avoiding the scattering of damaged parts on the back panel of the target photovoltaic component 200, so as to avoid polluting the soil and other ecological environments at the installation location of the target photovoltaic component 200. On the other hand, the main body 101 is designed to carry the target photovoltaic component 200, and the buckling belt 104 is buckled with the fixing belt 103 to jointly surround the front and sides of the target photovoltaic component 200. The entire carrier 100 holds the target photovoltaic component 200, which is beneficial for all-round protection of the target photovoltaic component 200 during the transportation of the target photovoltaic component 200. Therefore, no matter whether the back panel or other components of the target photovoltaic component 200 are damaged, the integrity of the target photovoltaic component 200 during the transportation process can be ensured, so as to avoid the scattering of any damaged parts of the target photovoltaic component 200, and further avoid polluting the soil and other ecological environments at the installation location of the target photovoltaic component 200.

[0126] Another embodiment of the present disclosure also provides a method for recycling photovoltaic modules, which uses the carrier provided in the above embodiment to recycle photovoltaic modules. The following will describe in detail the method for recycling photovoltaic modules provided in another embodiment of the present disclosure in conjunction with the accompanying drawings. It should be noted that the parts that are the same or corresponding to the above embodiment will not be repeated here.

[0127] refer to Figures 1 to 3 or Figures 7 to 11 The photovoltaic component recycling method includes the following steps: S101: screening out photovoltaic components to be recycled as target photovoltaic components 200; S102: providing the carrier 100 described in the above embodiment; S103: using the main body 101 to carry the target photovoltaic component 200; S104: using the adhesive part 102 to fix the back of the target photovoltaic component 200 to achieve a fixed connection between the main body 101 and the back of the target photovoltaic component 200; S105: wrapping the fixing belt 103 and the buckling belt 104 from the back of the target photovoltaic component 200 to the front of the target photovoltaic component 200, and buckling the fixing belt 103 and the buckling belt 104 on the front of the target photovoltaic component 200, so that the fixing belt 103 and the buckling belt 104 jointly wrap around the front and side of the target photovoltaic component 200 to achieve bundling of the target photovoltaic component 200.

[0128] In some embodiments, reference Figures 7 to 13 , the target photovoltaic module 200 includes a laminate 202 and a frame 203 for clamping the laminate 202, the back side of the target photovoltaic module 200 is the surface of the back sheet 212 in the laminate 202 away from the battery string, and the frame 203 includes a clamping portion 213 for clamping the laminate 202 and a bottom support portion 223 connected to the clamping portion 213. Based on this, the method of using the main body 101 to carry the target photovoltaic module 200 in step S103 includes: embedding the main body 101 and the adhesive portion 102 as a whole between the bottom support portion 223 and the back sheet 212.

[0129] In some embodiments, reference Figures 7 to 13 , the carrier 100 may further include: a plurality of shielding parts 105, any shielding part 105 is fixedly connected to the middle part of one of the fixing belt 103 or the buckling belt 104, and the shielding part 105 corresponds to the adhesive part 102. Based on this, in step S105, the fixing belt 103 and the buckling belt 104 are wrapped from the back of the target photovoltaic module 200 to the front of the target photovoltaic module 200, and when the fixing belt 103 and the buckling belt 104 are buckled on the front of the target photovoltaic module 200, the plane perpendicular to the first direction X is used as the reference plane, and the orthographic projection of the adhesive part 102 on the reference plane is located in the orthographic projection of the shielding part 105 on the reference plane.

[0130] In some embodiments, the method of achieving fixed connection between the main body 101 and the back surface of the target photovoltaic assembly 200 in step S104 may include:

[0131] If the target photovoltaic component 200 can work normally, first turn on the power of the target photovoltaic component 200, and make use of the local hot spot effect generated by the shielding part 105 of the target photovoltaic component 200 to make the adhesive part 102 melt by heat, so as to achieve the adhesion of the adhesive part 102 to the back side of the target photovoltaic component 200. Then, cut off the power of the target photovoltaic component 200, and the adhesive part 102 will cool down and solidify as the local hot spot effect disappears, so as to be fixedly connected to the back side of the target photovoltaic component 200.

[0132] If the target photovoltaic component 200 cannot work normally, a heating device, such as a hot air gun, is used to heat the adhesive portion 102 intensively so that the adhesive portion 102 is melted by the heat to achieve bonding between the adhesive portion 102 and the back side of the target photovoltaic component 200. Then, the heating device is turned off, and the adhesive portion 102 cools down and solidifies as the heating device stops heating, so as to be fixedly connected to the back side of the target photovoltaic component 200.

[0133] In other embodiments, regardless of whether the target photovoltaic component 200 can work normally, the adhesive portion 102 can be heated and melted by means of a heating device so as to be bonded to the back surface of the target photovoltaic component 200 .

[0134] In some embodiments, after the target photovoltaic component 200 is transported to the destination, the adhesive portion 102 can be heated again so that the adhesive portion 102 is melted again, so that the adhesive portion 102 can be detached from the back panel of the target photovoltaic component 200, so that the adhesive portion 102 can be subsequently fixedly connected to the back side of another target photovoltaic component 200, so that the carrier 100 can be used repeatedly.
