Description

Technical Field

[0001] The present invention relates to the technical field of solar cells, and more particularly, to a processing method for a solar module and a solar module. Background Art

[0002] In the prior art, the surface of a solar cell is covered with a thin film material, which is prone to wrinkling and deformation under high-temperature lamination operation, resulting in an increase in the defective rate of the product. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, the first object of the present invention is to provide a processing method for a solar module.

[0005] The second object of the present invention is to provide a solar module.

[0006] To achieve the above at least one object, according to a first aspect of the present invention, there is provided a processing method for a solar module, including: stacking a first encapsulation component and a cell layer from bottom to top in sequence above a heating device of a laminator, the first encapsulation component including a plurality of first embossed layers; controlling the laminator to laminate the cell layer to form a solar module.

[0007] The present application provides a processing method for a solar module. The solar module processed by this processing method includes a cell layer and a first encapsulation component. Among them, the first encapsulation component is located below the cell layer, and the first encapsulation component can play a certain protective role for the cell layer. The following describes the processing method for the solar module.

[0008] When processing the solar module, first stack the cell layer and the first encapsulation component from bottom to top in sequence. Among them, the first encapsulation component includes a plurality of first embossed layers, and the thicknesses of the plurality of first embossed layers are the same, and the plurality of first embossed layers are stacked in sequence. The solar module is processed and manufactured by a laminator, and the laminator includes a heating device, and when the heating device operates, the heating device can generate heat. During the process of processing the solar module, place the first encapsulation component and the cell layer on the upper part of the heating device of the laminator from bottom to top in sequence. Specifically, before placing the first encapsulation component and the cell layer into the laminator, the first encapsulation component and the cell layer can be placed on a carrier from bottom to top in sequence first, and then the carrier with the first encapsulation component and the cell layer is placed into the laminator, and the carrier is located above the heating device of the laminator. Among them, the carrier can be made of an aluminum alloy plate with a thickness of 2.5 mm to 3.5 mm, and the aluminum alloy plate has the characteristics of a heat conduction block. When the heating device of the laminator operates, the heating device generates heat. Since the first encapsulation component is located on the side of the cell layer facing the heating device, the heat generated by the heating device needs to be transferred to the cell layer through the first encapsulation component. Since the first encapsulation component in this application includes a plurality of first embossed layers, a certain distance can be provided between the cell layer and the heating device of the laminator. Compared with traditional solar modules, the distance between the cell layer and the heating device is increased, thereby reducing the heat transferred from the heating device to the cell layer. It can be understood that the thermal shrinkage of a part is related to the linear expansion coefficient of the material of the part and the temperature difference change of the part per unit time, that is, ΔL (thermal shrinkage of the part) = δ (linear expansion coefficient of the material of the part) × (part size + manufacturing tolerance / 2) × Δt (temperature difference of the part per unit time), and the thermal shrinkage ΔL is proportional to the temperature difference Δt. Therefore, by reducing the heat transferred from the heating device to the cell layer, the temperature difference of the cell layer per unit time can be reduced, and further the thermal shrinkage of the thin film on the surface of the cell layer can be reduced, the wrinkles on the surface of the cell layer can be reduced, and the appearance of the product can be improved. Among them, the thicknesses of the plurality of first embossed layers are the same.

[0009] Furthermore, after placing the first encapsulation component and the cell layer on the upper part of the heating device of the laminator, control the laminator to laminate the cell layer to form a solar module. The laminator can apply pressure to the cell layer so that the first encapsulation component and the cell layer are tightly bonded and connected to form a solar module.

[0010] According to the above processing method of the solar module of the present invention, the following distinguishing technical features may also be included:

[0011] In some technical solutions, optionally, before controlling the laminator to laminate the cell layer, it further includes: placing a second encapsulation component on the upper part of the cell layer.

[0012] In this technical solution, the processing method of the solar module is further defined. The solar module further includes a second encapsulation component. The first encapsulation component and the second encapsulation component are respectively located on both sides of the cell layer. Before controlling the laminator to laminate the cell layer, the second encapsulation component is placed above the cell layer. After the lamination operation is completed, the second encapsulation component, the cell layer and the first encapsulation component are tightly bonded and connected to form a solar module.

[0013] In some technical solutions, optionally, the cell layer has a bending part and a power generation part. The bending part can be folded, and the power generation part cannot be folded. The number of bending parts is at least one. The second encapsulation component includes a local pressure layer and a second embossing layer. The number of local pressure layers is the same as the number of bending parts. Placing the second encapsulation component above the cell layer specifically includes: placing the local pressure layer above the corresponding bending part; placing the second embossing layer above the local pressure layer.

[0014] In this technical solution, the processing method of the solar module is further defined. The cell layer has a bending part and a power generation part, wherein the bending part can be folded and the power generation part cannot be folded. The second encapsulation component includes a local pressure member and a second embossing layer, wherein the number of local pressure members is the same as the number of bending parts, and the two are arranged in one-to-one correspondence. The local pressure layer is located between the second embossing layer and the cell layer. The number of bending parts can be one or more. The following specifically defines the step of placing the second encapsulation component above the cell layer.

[0015] First, place the local pressure layer above the corresponding bending part, and then place the second embossing layer above the local pressure layer. Understandably, during the process of processing the solar module by the laminator, the laminator applies pressure to the second encapsulation component. By arranging local pressure members corresponding to the bending parts between the second embossing layer and the cell layer, the force on the bending parts can be increased, and correspondingly the force on the power generation part can be reduced. Since the bending part is a flexible part and the power generation part is a rigid part, it can play a certain protective role for the power generation part to prevent the power generation part from breaking or being damaged due to excessive force.

[0016] In some technical solutions, optionally, when the number of bending parts is multiple, the multiple bending parts are arranged at intervals on the power generation part.

[0017] In this technical solution, the cell layer is further defined. Specifically, the number of bending parts can be multiple. When the number of bending parts is multiple, the multiple bending parts are arranged at intervals on the power generation part. By arranging the bending parts with larger forces at intervals in sequence, the overall force on the cell layer can be made more balanced, and the lamination quality can be improved.

[0018] In some technical solutions, optionally, any local pressing layer includes a local embossing layer and a pressing member. Placing the local pressing layer above the corresponding bending part specifically includes: placing the local embossing layer above the corresponding bending part; placing the pressing member above the corresponding local embossing layer.

[0019] In this technical solution, the processing method of the solar module is further defined. Any local pressing layer includes a local embossing layer and a pressing member. The step of placing the local pressing layer above the corresponding bending part is specifically: first place the local embossing layer above the corresponding bending part, and then place the pressing member above the corresponding local embossing layer. Among them, the pressing member is made of a hard material. In this way, the pressure can be transmitted to the pressing member first, and then transmitted from the pressing member to the local embossing layer. Since the pressing member is made of a hard material, it has better pressure-bearing capacity and improves the reliability of the local pressing layer.

[0020] In some technical solutions, optionally, the thickness of the cell layer is H1, the thickness of the local embossing layer is H2, and the thickness of the pressing member is H3, where H1, H2, and H3 satisfy H3 = H1 - H2 - 1.5 mm.

[0021] In this technical solution, the processing method of the solar module is further defined. Specifically, the thickness of the cell layer is H1, the thickness of the local embossing layer is H2, and the thickness of the pressing member is H3, where H1, H2, and H3 satisfy H3 = H1 - H2 - 1.5 mm. In this way, it can not only make the strength of the pressing member meet the performance requirements of the product, but also avoid excessive product thickness.

[0022] In some technical solutions, optionally, before controlling the laminator to laminate the cell layer, it further includes: controlling the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C.

[0023] In this technical solution, the processing method of the solar module is further defined. Before controlling the laminator to laminate the cell layer, control the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C. By heating and maintaining the temperature inside the laminator within the range of 140°C to 150°C, the cell layer can be heated to a flexible state. Since the surfaces of the first embossing layer and the second embossing layer on both sides of the cell layer are uneven structures, the heated cell layer can be extended into the unevenness between the first embossing layer and the second embossing layer, enabling the cell layer to be embedded with the first embossing layer and the second embossing layer, and realizing the connection between the cell layer and the first embossing layer and the second embossing layer.

[0024] In some technical solutions, optionally, after controlling the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C, it further includes: controlling the air extraction device of the laminator to perform a vacuum pumping operation on the inside of the laminator, and the operation duration of the air extraction device is within a duration range of 300 s to 400 s.

[0025] In this technical solution, the processing method of the solar cell module is further defined. Specifically, after controlling the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C, control the air extraction device of the laminator to perform a vacuum pumping operation on the inside of the laminator, and the operation duration of the air extraction device is within a duration range of 300 s to 400 s. In this way, the environment where the first encapsulation component, the cell layer, and the second encapsulation component are located can tend to a vacuum environment, slow down the relative movement generated between the first encapsulation component, the cell layer, and the second encapsulation component when they are subsequently pressed, and improve the appearance consistency of the solar cell module.

[0026] In some technical solutions, optionally, controlling the laminator to laminate the cell layer specifically includes: controlling the laminator to laminate the cell layer at a first pressure for a first duration, the range of the first pressure is 10 kPa to 30 kPa, and the range of the first duration is 40 s to 110 s; controlling the laminator to laminate the cell layer at a second pressure for a second duration, the range of the second pressure is 45 kPa to 65 kPa, and the range of the second duration is 40 s to 110 s; controlling the laminator to laminate the cell layer at a third pressure for a third duration, the range of the third pressure is 90 kPa to 115 kPa, and the range of the third duration is 1350 s to 4000 s.

[0027] In this technical solution, the step of controlling the laminator to laminate the cell layer is specifically defined. The lamination of the cell layer is carried out in multiple steps. Specifically, the laminator used to laminate the cell layer includes an upper chamber and a lower chamber. The first encapsulation component, the cell layer, and the second encapsulation component are placed in the lower chamber. The heating device of the laminator is located in the lower chamber. There is a pressure difference between the upper chamber and the lower chamber, and the pressure for the laminator to laminate the cell layer can be changed by adjusting the air pressure in the upper chamber.

[0028] First, control the laminator to laminate the battery cell layer at a first pressure for a first duration. The range of the first pressure is 10 kPa to 30 kPa, and the range of the first duration is 40 s to 110 s. Specifically, through the vacuum pumping operation of the laminator, the air pressure in the lower chamber is -100 kPa. By adjusting the air pressure in the upper chamber to -90 kPa to -70 kPa, a pressure difference of 10 kPa to 30 kPa (i.e., the first pressure) can be formed between the upper chamber and the lower chamber. Then, control the laminator to laminate the battery cell layer at a second pressure for a second duration. The range of the second pressure is 45 kPa to 65 kPa, and the range of the second duration is 40 s to 110 s. Specifically, adjust the air pressure in the upper chamber to -55 kPa to -35 kPa, so that a pressure difference of 45 kPa to 65 kPa (i.e., the second pressure) can be formed between the upper chamber and the lower chamber. Finally, control the laminator to laminate the battery cell layer at a third pressure for a third duration. The range of the third pressure is 90 kPa to 115 kPa, and the range of the third duration is 1350 s to 4000 s. Specifically, adjust the air pressure in the upper chamber to -10 kPa to 15 kPa, so that a pressure difference of 90 kPa to 115 kPa (i.e., the third pressure) can be formed between the upper chamber and the lower chamber.

[0029] Understandably, when the battery cell layer is initially placed in the laminator, the battery cell layer is a rigid part. As the time in the high-temperature laminator increases, the battery cell layer gradually softens. By adopting a step-by-step pressure application lamination method, the battery cell layer can be prevented from breaking and damaging when initially pressed, and the lamination effect can be improved.

[0030] In a possible technical solution, the first embossed layer and the second embossed layer are Teflon cloth with double-sided pitting. The range of the thickness of the first embossed layer and the second embossed layer is 0.8 mm to 1.2 mm. The battery cell layer is a product with transparent film layers with a thickness of 25 μm to 50 μm provided on both the front and back sides, and at the same time, it is required that both the front and back sides have certain uneven textures. The battery cell layer includes a bending part and a power generation part. The bending part is flexibly arranged and can be repeatedly folded. The power generation part is rigidly arranged, and there is a solar power generation module in the power generation part that can receive sunlight for power generation. The main material of the power generation body in the power generation module includes one or more of crystalline silicon solar cells, compound solar cells, and thin-film solar cells. The local pressure application layer includes a local embossed layer and a pressure application part. The material of the local embossed layer is mainly Teflon cloth with double-sided pitting, and the material of the pressure application part is mainly substances made of hard and repeatedly high-temperature-resistant materials such as glass fiber, aluminum alloy, epoxy resin, and zinc alloy.

[0031] The second aspect of the present invention also proposes a solar module, which is made by using the processing method of the solar module proposed in the first aspect of the present invention.

[0032] The solar module provided in the second aspect of the present invention is fabricated by using the processing method of the solar module proposed in the first aspect of the present invention, and thus has all the beneficial effects of the processing method of the solar module.

Detailed implementation manners

[0050] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0051] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0052] Next, refer to Figures 1 to 13 Describe the processing method of the solar module and the solar module 100 provided according to some embodiments of the present invention.

[0053] The present invention provides a processing method of a solar module, as Figure 1 shown, one of the flow schematic diagrams of the processing method of the solar module according to the embodiment of the present invention is shown in the figure. Among them, the processing method includes the following steps S102 and S104:

[0054] S102: Stack the first encapsulation component and the cell layer on top of each other in sequence above the heating device of the laminator;

[0055] S104: Control the laminator to laminate the cell layer to form a solar module.

[0056] The present application provides a processing method of a solar module. As Figure 9 , Figure 10 and Figure 11As shown, the solar module 100 processed by this processing method includes a cell layer 120 and a first encapsulation component 110. Among them, the first encapsulation component 110 is located below the cell layer 120, and the first encapsulation component 110 can play a certain protective role for the cell layer 120. Among them, the first encapsulation component 110 includes a plurality of first embossed layers 111, such as Figure 13 As shown, the thicknesses of the plurality of first embossed layers 111 are the same (both are H4), and the plurality of first embossed layers are stacked in sequence. The processing method of the solar module will be described below.

[0057] When processing this solar module, first stack the cell layer and the first encapsulation component from bottom to top in sequence. The laminator includes a heating device, and when the heating device operates, the heating device can generate heat. During the process of processing the solar module, place the first encapsulation component and the cell layer on the upper side of the heating device of the laminator from bottom to top in sequence. Specifically, before placing the first encapsulation component and the cell layer into the laminator, the first encapsulation component and the cell layer can be placed on a carrier from bottom to top in sequence, and then the carrier with the first encapsulation component and the cell layer is placed into the laminator. The carrier is located on the upper side of the heating device of the laminator. Among them, the carrier can be made of an aluminum alloy plate with a thickness of 2.5 mm to 3.5 mm, and the aluminum alloy plate has the characteristics of a heat conduction block. When the heating device of the laminator operates, the heating device generates heat. Since the first encapsulation component is located on the side of the cell layer facing the heating device, the heat generated by the heating device needs to be transmitted to the cell layer through the first encapsulation component. Since the first encapsulation component in this application includes a plurality of first embossed layers, a certain distance can be provided between the cell layer and the heating device of the laminator. Compared with traditional solar modules, the distance between the cell layer and the heating device is increased, thereby reducing the heat transferred from the heating device to the cell layer. It can be understood that the thermal shrinkage of a part is related to the linear expansion coefficient of the material of the part and the temperature difference change of the part per unit time, that is, ΔL (thermal shrinkage of the part) = δ (linear expansion coefficient of the material of the part) × (part size + manufacturing tolerance / 2) × Δt (temperature difference of the part per unit time), and the thermal shrinkage ΔL is proportional to the temperature difference Δt. Therefore, by reducing the heat transferred from the heating device to the cell layer, the temperature difference of the cell layer per unit time can be reduced, and further the thermal shrinkage of the thin film on the surface of the cell layer can be reduced, the wrinkles on the surface of the cell layer can be reduced, and the appearance of the product can be improved. Among them, the thicknesses of the plurality of first embossed layers are the same.

[0058] Furthermore, after placing the first encapsulation component and the cell layer on the upper side of the heating device of the laminator, control the laminator to laminate the cell layer to form a solar module. The laminator can apply pressure to the cell layer to make the first encapsulation component and the cell layer fit tightly and connect to form a solar module.

[0059] As Figure 2 shown, FIG. shows the second schematic flow chart of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S202 to S206:

[0060] S202: Stack the first encapsulation component and the cell layer on top of each other in sequence above the heating device of the laminator;

[0061] S204: Place the second encapsulation component above the cell layer;

[0062] S206: Control the laminator to laminate the cell layer to form a solar module.

[0063] In this embodiment, the processing method of the solar module is further defined. The solar module further includes a second encapsulation component. The first encapsulation component and the second encapsulation component are respectively located on both sides of the cell layer. Before controlling the laminator to laminate the cell layer, place the second encapsulation component above the cell layer. After completing the lamination operation, the second encapsulation component, the cell layer and the first encapsulation component are tightly bonded together to form a solar module.

[0064] In an embodiment according to the present application, as Figure 9 , Figure 10 and Figure 11 shown, the cell layer 120 has a bent portion 121 and a power generation portion 122. The bent portion 121 is foldable, the power generation portion 122 is not foldable, the number of the bent portions 121 is at least one, the second encapsulation component 130 includes a local pressure layer 131 and a second embossing layer 134, and the number of the local pressure layers 131 is the same as the number of the bent portions 121. As Figure 3 shown, FIG. shows the third schematic flow chart of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S302 to S308:

[0065] S302: Stack the first encapsulation component and the cell layer on top of each other in sequence above the heating device of the laminator;

[0066] S304: Place the local pressure layer above the corresponding bent portion;

[0067] S306: Place the second embossing layer above the local pressure layer;

[0068] S308: Control the laminator to laminate the cell layer to form a solar module.

[0069] In this embodiment, the processing method of the solar module is further defined. As Figure 9 ,Figure 10 and Figure 11 As shown in Figure 11 , the cell layer 120 has a bent portion 121 and a power generation portion 122, wherein the bent portion 121 is foldable and the power generation portion 122 is not foldable. The second encapsulation component 130 includes a local pressing member and a second embossing layer 134. Among them, the number of local pressing members is the same as that of the bent portions 121, and they are arranged in one-to-one correspondence. The local pressing layer 131 is located between the second embossing layer 134 and the cell layer 120. The number of the bent portions 121 can be one or more. The following specifically defines the step of placing the second encapsulation component above the cell layer.

[0070] First, place the local pressing layer above the corresponding bent portion, and then place the second embossing layer above the local pressing layer. It can be understood that during the process of processing the solar module by the laminator, the laminator applies pressure to the second encapsulation component. By arranging local pressing members corresponding to the bent portions between the second embossing layer and the cell layer, the force on the bent portions can be increased, and correspondingly, the force on the power generation portion can be reduced. Since the bent portions are flexible members and the power generation portions are rigid members, it can play a certain protective role for the power generation portions to prevent the power generation portions from breaking or being damaged due to excessive force.

[0071] In some embodiments, optionally, as Figure 10 and Figure 11 shown, when the number of the bent portions 121 is multiple, the multiple bent portions 121 are arranged at intervals on the power generation portion 122.

[0072] In this embodiment, the cell layer 120 is further defined. Specifically, as Figure 9 and Figure 10 shown, the number of the bent portions 121 can be multiple. When the number of the bent portions 121 is multiple, the multiple bent portions 121 are arranged at intervals on the power generation portion 122. By arranging the bent portions 121 with larger forces at intervals in sequence, the overall force on the cell layer 120 can be more balanced, and the lamination quality can be improved.

[0073] In an embodiment according to the present application, as Figure 9 , Figure 10 and Figure 11 shown, any local pressing layer 131 includes a local embossing layer 132 and a pressing member 133. As Figure 4 shown, the figure shows the fourth schematic flow chart of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S402 to S410:

[0074] S402: Stack the first encapsulation component and the cell layer in sequence from bottom to top above the heating device of the laminator;

[0075] S404: Place the local embossing layer above the corresponding bending part;

[0076] S406: Place the pressing member above the corresponding local embossing layer;

[0077] S408: Place the second embossing layer above the pressing member;

[0078] S410: Control the laminator to laminate the cell layer to form a solar module.

[0079] In this embodiment, the processing method of the solar module is further defined. For example Figure 9 , Figure 10 and Figure 11 shown, any local pressing layer 131 includes a local embossing layer 132 and a pressing member 133. The step of placing the local pressing layer above the corresponding bending part is specifically: first place the local embossing layer above the corresponding bending part, and then place the pressing member above the corresponding local embossing layer. Among them, the pressing member is made of a hard material. In this way, the pressure can be transmitted to the pressing member first, and then transmitted from the pressing member to the local embossing layer. Since the pressing member is made of a hard material, it has better pressure-bearing capacity and improves the reliability of the local pressing layer.

[0080] In some embodiments, optionally, as Figure 12 shown, the thickness of the cell layer 120 is H1, the thickness of the local embossing layer 132 is H2, and the thickness of the pressing member 133 is H3. Among them, H1, H2, and H3 satisfy H3 = H1 - H2 - 1.5 mm.

[0081] In this embodiment, the processing method of the solar module is further defined. Specifically, as Figure 11 shown, the thickness of the cell layer 120 is H1, the thickness of the local embossing layer 132 is H2, and the thickness of the pressing member 133 is H3. Among them, H1, H2, and H3 satisfy H3 = H1 - H2 - 1.5 mm. In this way, not only can the strength of the pressing member 133 meet the performance requirements of the product, but also the excessive thickness of the product can be avoided.

[0082] In an embodiment according to the present application, as Figure 5 shown, the figure shows the fifth flow diagram of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S502 to S512:

[0083] S502: Stack the first encapsulation component and the cell layer from bottom to top above the heating device of the laminator in sequence;

[0084] S504: Place the local embossing layer above the corresponding bending part;

[0085] S506: Place the pressing member above the corresponding local embossing layer;

[0086] S508: Place the second embossing layer above the pressing member;

[0087] S510: Control the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C;

[0088] S512: Control the laminator to laminate the cell layer to form a solar module.

[0089] In this embodiment, the processing method of the solar module is further defined. Before controlling the laminator to laminate the cell layer, control the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C. By heating and maintaining the temperature inside the laminator within the range of 140°C to 150°C, the cell layer can be heated to a flexible state. Since the surfaces of the first embossing layer and the second embossing layer on both sides of the cell layer are uneven structures, the heated cell layer can extend into the unevenness between the first embossing layer and the second embossing layer, enabling the cell layer to be fitted together with the first embossing layer and the second embossing layer, realizing the connection between the cell layer and the first embossing layer and the second embossing layer.

[0090] In one embodiment according to the present application, as Figure 6 shown, FIG. shows the sixth flow diagram of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S602 to S614:

[0091] S602: Stack the first encapsulation component and the cell layer from bottom to top above the heating device of the laminator in sequence;

[0092] S604: Place the local embossing layer above the corresponding bending part;

[0093] S606: Place the pressing member above the corresponding local embossing layer;

[0094] S608: Place the second embossing layer above the pressing member;

[0095] S610: Control the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C;

[0096] S612: Control the air extraction device of the laminator to perform a vacuum operation on the inside of the laminator, and the running time of the air extraction device is within the time range of 300 s to 400 s;

[0097] S614: Control the laminator to laminate the cell layer to form a solar module.

[0098] In this embodiment, the processing method of the solar module is further defined. Specifically, after the heating device of the laminator heats the inside of the laminator to a temperature range of 140°C to 150°C, the air extraction device of the laminator is controlled to perform a vacuum pumping operation on the inside of the laminator, and the operation duration of the air extraction device is within the duration range of 300 s to 400 s. In this way, the environment where the first encapsulation component, the cell layer, and the second encapsulation component are located tends to be a vacuum environment, slowing down the relative movement between the first encapsulation component, the cell layer, and the second encapsulation component when they are subsequently pressed, and improving the appearance consistency of the solar module.

[0099] In one embodiment according to the present application, as Figure 7 shown, FIG. shows the seventh schematic flow chart of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S702 to S718:

[0100] S702: Stack the first encapsulation component and the cell layer on top of each other in sequence from bottom to top above the heating device of the laminator;

[0101] S704: Place the local embossing layer above the corresponding bending part;

[0102] S706: Place the pressing member above the corresponding local embossing layer;

[0103] S708: Place the second embossing layer above the pressing member;

[0104] S710: Control the heating device of the laminator to heat the inside of the laminator to a temperature range of 140°C to 150°C;

[0105] S712: Control the air extraction device of the laminator to perform a vacuum pumping operation on the inside of the laminator, and the operation duration of the air extraction device is within the duration range of 300 s to 400 s;

[0106] S714: Control the laminator to laminate the cell layer with a first pressure for a first duration, the range of the first pressure is 10 kPa to 30 kPa, and the range of the first duration is 40 s to 110 s;

[0107] S716: Control the laminator to laminate the cell layer with a second pressure for a second duration, the range of the second pressure is 45 kPa to 65 kPa, and the range of the second duration is 40 s to 110 s;

[0108] S718: Control the laminator to laminate the cell layer with a third pressure for a third duration, the range of the third pressure is 90 kPa to 115 kPa, and the range of the third duration is 1350 s to 4000 s.

[0109] In this embodiment, the step of controlling the laminator to laminate the cell layer is specifically defined. The control of the laminator to laminate the cell layer is carried out in multiple steps. Specifically, the laminator used for laminating the cell layer includes an upper chamber and a lower chamber. The first encapsulation component, the cell layer, and the second encapsulation component are placed in the lower chamber. The heating device of the laminator is located in the lower chamber. There is a pressure difference between the upper chamber and the lower chamber. By adjusting the air pressure in the upper chamber, the pressure used by the laminator to laminate the cell layer can be changed.

[0110] First, control the laminator to laminate the cell layer at a first pressure for a first duration. The range of the first pressure is 10 kPa to 30 kPa, and the range of the first duration is 40 s to 110 s. Specifically, through the vacuum pumping operation of the laminator, the air pressure in the lower chamber is -100 kPa. By adjusting the air pressure in the upper chamber to -90 kPa to -70 kPa, a pressure difference of 10 kPa to 30 kPa (i.e., the first pressure) can be formed between the upper chamber and the lower chamber. Then, control the laminator to laminate the cell layer at a second pressure for a second duration. The range of the second pressure is 45 kPa to 65 kPa, and the range of the second duration is 40 s to 110 s. Specifically, adjust the air pressure in the upper chamber to -55 kPa to -35 kPa, so that a pressure difference of 45 kPa to 65 kPa (i.e., the second pressure) can be formed between the upper chamber and the lower chamber. Finally, control the laminator to laminate the cell layer at a third pressure for a third duration. The range of the third pressure is 90 kPa to 115 kPa, and the range of the third duration is 1350 s to 4000 s. Specifically, adjust the air pressure in the upper chamber to -10 kPa to 15 kPa, so that a pressure difference of 90 kPa to 115 kPa (i.e., the third pressure) can be formed between the upper chamber and the lower chamber.

[0111] It can be understood that when the cell layer is initially placed in the laminator, the cell layer is a rigid part. As the time in the high-temperature laminator increases, the cell layer gradually softens. By adopting a step-by-step pressurization laminating method, the breakage of the cell layer during initial compression can be avoided, and the laminating effect can be improved.

[0112] In a possible embodiment, the first embossed layer and the second embossed layer are Teflon fabrics with double-sided pitting, and the thickness range of the first embossed layer and the second embossed layer is 0.8 mm to 1.2 mm. The battery cell layer is a product with transparent film layers with a thickness of 25 μm to 50 μm provided on both the front and back sides, and at the same time, it is required that there are certain uneven textures on both the front and back sides. The battery cell layer includes a bending part and a power generation part. The bending part is flexibly arranged and can be repeatedly folded. The power generation part is rigidly arranged, and there is a solar power generation module in the power generation part that can receive sunlight for power generation. The main material of the power generation body in the power generation module includes one or more of crystalline silicon solar cells, compound solar cells, and thin-film solar cells. The local pressing layer includes a local embossed layer and a pressing member. The material of the local embossed layer is mainly Teflon fabric with double-sided pitting, and the material of the pressing member is mainly substances made of hard and repeatedly high-temperature-resistant materials such as glass fiber, aluminum alloy, epoxy resin, and zinc alloy.

[0113] In a possible embodiment, as Figure 8 shown, Figure 8 shows a schematic flow diagram of the processing method of the solar module according to the embodiment of the present invention. Among them, the processing method includes the following steps S802 to S814:

[0114] S802: Place the carrier;

[0115] S804: Stack multiple first embossed layers on the carrier in sequence;

[0116] S806: Lay the battery cell layer on the first embossed layer;

[0117] S808: Place the local pressing layer on the corresponding bending part of the battery cell layer;

[0118] S810: Place the second embossed layer above the local pressing layer;

[0119] S812: Modify the lamination parameters of the laminator, place the carrier with the first embossed layer, the battery cell layer, the local pressing layer, and the second embossed layer into the laminator, and control the lamination to perform the lamination operation;

[0120] S814: Cut the first embossed layer, the battery cell layer, the local pressing layer, and the second embossed layer that have completed the lamination operation.

[0121] In this embodiment, the lamination parameters defined in step S812 are specifically shown in Table 1. The lamination operation in this step includes one-stage lamination, two-stage lamination, and three-stage lamination. Among them, one-stage lamination uses one-stage pressure and one-stage pressurization time, two-stage lamination uses two-stage pressure and two-stage pressurization time, and three-stage lamination uses three-stage pressure and three-stage pressurization time. The laminator includes an upper chamber and a lower chamber. The first encapsulation component, the cell layer, and the second encapsulation component are placed in the lower chamber. There is a pressure difference between the upper chamber and the lower chamber, and the pressure of the lamination operation can be changed by adjusting the air pressure in the upper chamber. Specifically, through the vacuum pumping operation of the laminator, the air pressure in the lower chamber is -100 kPa. The pressures in the upper chamber during each stage of lamination operation are shown as one-stage pressure, two-stage pressure, and three-stage pressure in Table 1. When performing the lamination operation, a vacuum pumping operation is also carried out, and the duration of the vacuum pumping operation is shown in Table 1. When performing the lamination operation, a heating operation is also carried out, and the process temperature of heating is shown in Table 1.
