Description

Technical Field

[0001] The embodiments of the present invention relate to a solar cell manufacturing apparatus and a solar cell manufacturing method. Background Technology

[0002] Solar cells are formed by placing diodes with pn junctions on a substrate. When sunlight reaches the solar cell, it generates excitons, or electron-hole pairs, which split into electrons and holes. The electrons and holes migrate to the n-layer and p-layer, respectively, thereby generating photovoltaic power across the pn junction. Overlapping refers to the process of electrically connecting multiple solar cells to each other by placing wires on the solar cells to form a single solar cell module.

[0003] Here, the process of joining solar cells and wires includes applying conductive adhesive (ECA) to the surface of the solar cell and joining the wires to the solar cell.

[0004] The process of using conductive adhesives to bond solar cells to wires is a next-generation process for manufacturing solar cells, and various studies have been conducted on its specific implementation. Summary of the Invention

[0051] A solar cell manufacturing apparatus is a device used to connect solar cells C and wires w to form a solar cell module. Solar cell C includes a semiconductor junction region having a pn junction surface, and when irradiated with energy of a certain order of magnitude or more, solar cell C generates an electromotive force to convert light energy into electrical energy. The semiconductor material included in solar cell C is not limited to specific materials and may include silicon (monocrystalline silicon, polycrystalline silicon, and amorphous silicon), gallium arsenide, cadmium telluride, cadmium sulfide, indium phosphide, copper indium gallium selenide (CIGS), organic dyes, or mixtures thereof.

[0052] The wire w is a conductor used to electrically connect multiple solar cells C to each other, and is configured to connect the front and back sides of adjacent solar cells C to each other. For example, the wire w can be electrically connected to the solar cells C by a curing process. Alternatively, the wire w can be electrically connected to the solar cells C by a conductive adhesive (ECA).

[0053] Reference Figures 1 to 12 According to an embodiment of the present invention, a solar cell manufacturing apparatus includes: a first base 11 on which a platform 100 on which a solar cell C is disposed is disposed and transported; a second base 12 disposed below the first base 11 and transporting the platform 100 supplied from the first base 11; a first platform lift 40 connected to the other end 11b of the first base 11 and one end 12a of the second base 12, and transporting the platform 100 disposed on the first base 11 to the second base 12; and a second platform lift 40' connected to one end 11a of the first base 11 and the other end 12b of the second base 12, and transporting the platform 100 disposed on the second base 12 to the first base 11, wherein the platform 100 circulates between the first base 11 and the second base 12.

[0054] Reference Figure 1 The curing process can be performed simultaneously with the solar cell C passing through the curing unit 20 and each solar cell C being placed on the stage 100. The solar cell C can be supplied via the battery supply unit 80. The battery supply unit 80 can supply solar cells C with conductive adhesive (ECA) applied.

[0055] Battery feeder 80 can deliver solar cell C with conductive adhesive applied to battery clamp feeder 90. Additionally, referring to battery clamp feeder 90, clamp feeder 70 can be disposed on the opposite side of battery feeder 80 to supply clamp J to battery clamp feeder 90.

[0056] The battery clamp feeder 90 can transport the solar cell C and the clamp J to the upper side of the base 10 via the battery clamp transport unit 91. The battery clamp transport unit 91 can clamp the solar cell C and the clamp J together and can rotate the solar cell C and the clamp J around the rotation axis 91a to place the solar cell C and the clamp J on the upper side of the base 10. Then, the solar cell C and the clamp J placed on the upper side of the base 10 can be sequentially placed on the stage 100, and the stage 100 can then enter the curing zone Z6 together with the solar cell C and the clamp J placed thereon to undergo curing treatment.

[0057] A stage supply area Z2 may be provided with a stage feeder 40. The stage feeder 40 can supply the stage 100 to the stage supply area Z2. The solar cell C and the fixture J can be placed on the stage 100 supplied to the stage supply area Z2, and the stage 100, together with the solar cell C and the fixture J placed thereon, can pass through the curing area Z6 to allow the curing process for the solar cell C to be performed.

[0058] On the stage 100, which has passed through the curing zone Z6 and the exit zone Z7 described below, the clamp J can be separated from the stage 100 and the solar cell C and recovered by the clamp recovery unit 71. The solar cell C, which is separated from the clamp J and placed on the stage 100, can be separated from the stage 100 and unloaded by the battery conveyor 50. The clamp recovery unit 71 can supply the recovered clamp to the clamp feeder 70, and the clamp feeder 70 can then resupply the recovered clamp to the battery clamp feeder 90.

[0059] The stage 100, separated from the fixture J and the solar cell C, can be recovered by the stage recovery unit 40'. The stage recovery unit 40' is connected to the stage feeder 40, and the stage 100 recovered by the stage recovery unit 40' can be transported to the stage feeder 40. The stage feeder 40 can then resupply the transported stage 100 to the stage supply area Z2.

[0060] The platform 100 can be transported from the platform supply area Z2 to the exit area Z7 on the base 10. The platform 100 can also be transported from the platform supply area Z2 to the solar cell placement area Z3. In the solar cell placement area Z3, solar cells C supplied from the battery clamp feeder 90 can be placed on the platform 100 via the battery clamp transport unit 91.

[0061] With the solar cell C mounted on the stage 100, the stage 100 can be transported from the solar cell mounting area Z3 to the fixture fixing area Z4. In the fixture fixing area Z4, once the fixture J is mounted on the stage 100, the solar cell C can be fixed to the stage 100.

[0062] With the solar cell C and the fixture J mounted on the stage 100, the stage 100 can be transported from the fixture fixing area Z4 to the preheating area Z5. In the preheating area Z5, the solar cell C mounted on the stage 100 can be preheated by the first heater H1 provided in the preheating area Z5 before the curing process.

[0063] With the solar cell C and the fixture J mounted on the stage 100, the stage 100 can be transported from the preheating zone Z5 to the curing zone Z6. After entering the curing zone Z6, the solar cell C mounted on the stage 100 can undergo curing treatment.

[0064] After passing through the curing zone Z6, the stage 100, on which the solar cell C and the fixture J are mounted, can be conveyed to the exit zone Z7. In the exit zone Z7, the first heater H1 can be configured to act as a temperature buffer structure to prevent the solar cell C from experiencing sudden temperature changes by slowly reducing the temperature of the solar cell C mounted on the stage 100 as the stage 100 is removed from the high-temperature environment of the curing zone Z6.

[0065] The platform 100 can be conveyed to the platform recovery unit 40' via the exit area Z7. Here, the clamp J can be separated from and recovered from the platform 100 and the solar cell C via the clamp recovery unit 71. The clamp recovery unit 71 can be located in the area corresponding to the platform recovery unit 40'. Therefore, the clamp recovery unit 71 can recover the clamp J located on the platform recovery unit 40'. Alternatively, the clamp recovery unit 71 can be placed between the exit area Z7 and the platform recovery unit 40'. Therefore, the clamp recovery unit 71 can recover the clamp J located in the area corresponding to the clamp recovery area. Alternatively, the clamp recovery unit 71 can be located between the exit area Z7 and the second platform elevator 40'. Therefore, the clamp recovery unit 71 can recover the clamp J located in the area corresponding to the clamp recovery area.

[0066] Additionally, the solar cell C can be detached from and removed from the platform 100 (from which the clamp J is recovered) via the battery conveyor 50. Then, the platform 100 can be conveyed to the platform feeder 40 via the platform recovery unit 40' and can be resupplyed to the platform supply area Z2.

[0067] The wire feeder 30 can be located on one side of the stage supply area Z2. The wire feeder 30 can extend and transport the wire w to the stage supply area Z2, the solar cell placement area Z3, and the clamp fixing area Z4 via a clamp for securing the wire w. Here, the extended wire w can be guided by a wire groove formed on the stage 100. Therefore, the wire supply area Z1 can be a region including the wire feeder 30, the stage supply area Z2, the solar cell placement area Z3, and the clamp fixing area Z4.

[0068] The wire w can be disposed on both the upper and lower surfaces of the solar cell C. The wire w disposed on the lower surface of the solar cell C can be guided by a wire groove formed on the stage 100. The wire w disposed on the upper surface of the solar cell C can be fixed to the upper surface of the solar cell C by pressing the wire w against the upper surface of the solar cell C via a clamp J. The clamp J can fix the wire w so that it will not lift or deviate from a specific position when connected to the upper surface of the solar cell C.

[0069] The wire feeder 30 may include: a cutter configured to cut the wound wire to a preset first length; and a clamp configured to extend and convey the first length of wire through the stage supply area Z2 and the solar cell placement area Z3 to the clamp fixing area Z4.

[0070] Reference Figure 2 In order to perform the curing process, the stage 100 is supplied to the stage supply area Z2 and the solar cell placement area Z3. Figure 2 (a)), and when the first wire w1 is supplied via the wire feeder 30 ( Figure 2 (b) The battery clamp conveying unit 91 simultaneously places the pair of first solar cells C1 and first clamps J1 on the first conductor w1. Figure 2 (c) At this time, the battery clamp conveying unit 91 places the first solar cell C in the solar cell placement area Z3 and places the first clamp J in the clamp fixing area Z4.

[0071] Then, the stage 100, the first wire w1, the first clamp J1, and the first solar cell C1 are conveyed on the base 10 to the curing zone Z6 at a pitch P, and the second wire w is supplied to the conveyed solar cell C. Figure 2 (d)

[0072] Reference Figure 3 The pitch P can be the width P of the stage. Here, the preheating zone Z5 can have a width corresponding to the width P of the stage. Specifically, each of the width of the preheating zone Z5 and the width P of the stage can refer to the width in a direction parallel to the conveying direction of the solar cell C.

[0073] Then, the battery clamp conveying unit 91 simultaneously places the paired second clamps J2 and the second solar cell C2 onto the second conductor w2. Figure 2 (e)).

[0074] Refer again Figure 1The clamps and solar cells placed on the platform 100 at the platform recovery unit 40' are picked up by the clamp recovery unit 71 and the battery conveyor 50 respectively to separate them from the platform 100.

[0075] Then, the first wire w1, the first clamp J1, the first solar cell C1, the second wire w2, the second clamp J2, and the second solar cell C2 are conveyed on the base 10 to the curing area Z6 at a pitch P, and the third wire w3 is supplied to the conveyed solar cell C. Figure 2 (f)

[0076] Then, the battery clamp conveying unit 91 simultaneously places the pair of third clamps J3 and third solar cells C3 onto the third conductor w3. Figure 2 (g)). See again. Figure 1 The clamps and solar cells placed on the platform 100 at the platform recovery unit 40' are picked up by the clamp recovery unit 71 and the battery conveyor 50 and separated from the platform 100.

[0077] In the above sequence, the wire w and the clamp J are placed on the solar cell C on the stage 100, and the curing process can be carried out in the curing zone Z6, wherein the wire w is bonded to the upper and lower surfaces of the solar cell C.

[0078] The stage 100 can transport the solar cell C and the wires w disposed on the solar cell C to the curing zone Z6. The stage 100 can enter the curing zone Z6 via tracks L formed on opposite sides of the base 10, and can also leave the curing zone Z6 via tracks L. (See reference...) Figure 3 Multiple stages 100 can be continuously supplied to the curing zone Z6 in a connected state.

[0079] Multiple platforms 100 can each be equipped with multiple solar cells C, each solar cell C having a wire w on it. For example... Figure 2 As shown, a wire disposed on the upper surface of a solar cell C can extend to be disposed on the lower surface of another solar cell C connected to the first solar cell C. Conversely, a wire disposed on the lower surface of a solar cell C can extend to be disposed on the upper surface of another solar cell C connected to the first solar cell C. Here, both the upper and lower surfaces of a solar cell C can have wires disposed thereon.

[0080] The base 10 of the transport stage 100 is formed in an elongated shape, so that the stage 100 can move into the curing area Z6 on the base 10. A guide G is formed at the lower end of the stage 100, which is connected to the track L formed on the base 10 and allows the stage 100 to move along the track L.

[0081] Two guide rods SH can be formed parallel to the tracks L formed on opposite sides of the base 10. When the platform 100 is transported along the track L, the platform 100 can be transported with its lower end in contact with the guide rods SH.

[0082] Each track in track L extends from one end of base 10 to the other end of base 10 along its length. On the other hand, guide rod SH extends through preheating zone Z5, curing zone Z6 and outlet zone Z7.

[0083] According to this embodiment, the device may further include a first heater H1 disposed between two guide rods SH on the upper surface of the base 10. In this embodiment, the first heater H1 is composed of three heaters and has a tubular structure extending in a length direction parallel to the guide rods SH. However, it should be understood that the number and shape of the first heater H1 are not limited thereto.

[0084] The first heater H1 can have a length corresponding to that of the guide rod SH. Therefore, like the guide rod SH, the first heater H1 extends through the preheating zone Z5, the curing zone Z6, and the outlet zone Z7. In this structure, preheating of the solar cell C can be performed in the preheating zone Z5, curing of the solar cell C can be performed in the curing zone Z6, and a process to reduce the temperature difference between the curing zone Z6 and the outside can be performed in the outlet zone Z7.

[0085] According to this embodiment, the first heater H1 can be a cartridge heater.

[0086] The stage 100, on which the solar cell C is mounted, can pass over the first heater H1. As the stage 100 passes over the first heater H1, the first heater H1 can perform a curing process on the solar cell C mounted on the stage 100.

[0087] The curing unit 20 is disposed above the base 10. The curing unit 20 is formed as a box shape with an opening at its lower surface. The curing unit 20 may be formed as an elongated shape in the length direction of the base 10 to cover the central portion of the base 10.

[0088] The curing unit 20 can be configured to cover the curing area Z6 of the base 10. However, in the event of a malfunction or maintenance of the curing unit 20, the curing unit 20 can be opened to allow maintenance work to be performed on its interior.

[0089] Multiple solar cells C disposed within the curing unit 20 can be cured within the curing unit 20, wherein each solar cell C is mounted on a corresponding stage 100, and the curing unit 20 is coupled to the central portion of the base 10. The curing unit 20 can be configured to accommodate as many stages 100 on which solar cells C are mounted as possible, so as to maximize the number of solar cells C to be cured.

[0090] Reference Figure 5 The curing unit 20 may have a plurality of second heaters H2 disposed on its inner top 21. According to this embodiment, the second heaters H2 consist of four heaters and have a tube structure extending in a length direction parallel to the length direction of the curing unit 20. However, it should be understood that the number and shape of the second heaters H2 are not limited thereto.

[0091] According to this embodiment, the second heater H2 can be an infrared (IR) heater.

[0092] Reference Figure 5 The base may include an exit zone Z7, on which a stage 100, on which solar cells C are mounted, is transported from the curing zone Z6 to the exit zone Z7. Here, a first heater H1 may be disposed in the curing zone Z6, the preheating zone Z5, and the exit zone Z7. That is, the first heater H1 may extend beyond both ends of the second heater H2. After the curing process, the solar cells C transported from the curing unit 20 can undergo post-heating by the first heater H1 in the exit zone Z7. In other words, the first heater H1 can be disposed in the exit zone Z7 so that when the stage 100 is transported from the high-temperature environment within the curing zone Z6 to the outside of the curing zone Z6, the solar cells C mounted on the stage 100 will not experience a sudden temperature change. The first heater H1 disposed in the exit zone Z7 can act as a temperature buffer to slowly reduce the temperature of the solar cells C mounted on the stage 100. This further improves the quality of the cured solar cells.

[0093] Reference Figures 1 to 12According to one embodiment of the present invention, a solar cell manufacturing apparatus includes: a first base 11 on which a platform 100 on which a solar cell C is disposed is disposed and transported; a second base 12 disposed below the first base 11 and transporting the platform 100 supplied from the first base 11; a first platform lift 40 connected to the other end 11b of the first base 11 and one end 12a of the second base 12, and transporting the platform 100 disposed on the first base 11 to the second base 12; and a second platform lift 40' connected to one end 11a of the first base 11 and the other end 12b of the second base 12, and transporting the platform 100 disposed on the second base 12 to the first base 11, wherein the platform 100 circulates between the first base 11 and the second base 12.

[0094] This structure allows the stage to circulate via a first base 11 and a second base 12 arranged vertically and configured to transport the stage 100, and a first stage lift 40 and a second stage lift 40' connecting the first base 11 and the second base 12 at their ends in the vertical direction. In this structure, the stage 100 with solar cells mounted thereon can be continuously supplied during the curing process, during which wires are connected to the solar cells mounted on the stage 100.

[0095] Furthermore, since the first base 11 and the second base 12 of the platform 100 are arranged vertically, the platform 100 can be circulated in the vertical direction, thereby ensuring the space utilization rate for transporting the platform 100.

[0096] The solar cell C can be moved to the curing zone Z6 while it is mounted on the stage 100. In the curing zone Z6, the solar cell C with conductive adhesive applied and the wires w disposed on the surface of the solar cell C can be cured by the curing unit 20.

[0097] A platform 100 may be disposed on a first base 11, and a second base 12 may be disposed below the first base 11. When multiple platforms 100 are adjacent to each other, the platforms 100 may be transported on the first base 11 and the second base 12.

[0098] The first base 11 can transport multiple platforms 100 in a first direction X. That is, the multiple platforms 100 can be transported from one end 11a of the first base 11 toward the other end 11b of the first base 11 in contact with each other. In this case, the multiple platforms 100 can be transported at one time at a pitch P corresponding to the width of each platform.

[0099] When multiple platforms 100 are transported on the first base 11, when the multiple platforms 100 move one pitch P in the first direction X, the platform 100 located at the other end 11b of the first base 11 can be placed on the first platform elevator 40 located on the first layer 41.

[0100] A first platform lift 40 may be disposed on one side of the first base 11 and the second base 12, and may be selectively connected to the first base 11 and the second base 12 by means of lifting. The first platform lift 40 may be movable for lifting between the two layers (i.e., the first layer 41 and the second layer 42). The first layer 41 may be connected to the other end 11b of the first base 11. The second layer 42 may be connected to one end 12a of the second base 12. The first platform lift 40 may receive a platform 100. With the platform 100 positioned on the first platform lift 40, the first platform lift 40 may transport the platform 100 from the first base 11 to the second base 12 by descending from the first layer 41 to the second layer 42.

[0101] Here, the first platform elevator 40 can receive the platform 100 located at the other end 11b of the first base 11 on the first layer 41, and can lower the received platform 100 from the first layer 41 to the second layer 42 connected to one end 12a of the second base 12.

[0102] The second base 12 can transport multiple platforms 100 in a direction opposite to the first direction X. That is, the multiple platforms 100 can be transported from one end 12a of the second base 12 toward the other end 12b of the second base 12 in contact with each other. In this case, the multiple platforms 100 can be transported at one time at a pitch P corresponding to the width of each platform.

[0103] When multiple platforms 100 are transported on the second base 12, when the multiple platforms 100 move one pitch P in the first direction X, the platform 100 located at the other end 12b of the second base 12 can be placed on the second platform elevator 40' located on the second layer 42'.

[0104] The second platform lift 40' can be located on the opposite side of the first base 11 and the second base 12, and can be selectively connected to the first base 11 and the second base 12 by lifting. The second platform lift 40' can be movable for lifting between the two layers (i.e., the first layer 41' and the second layer 42'). The first layer 41' can be connected to one end 11a of the first base 11. The second layer 42' can be connected to the other end 12b of the second base 12. The second platform lift 40' can receive the platform 100. When the platform 100 is placed on the second platform lift 40', the second platform lift 40' can transport the platform 100 placed on the second base 12 to the first base 11 while rising from the second layer 42' to the first layer 41'.

[0105] Here, the second platform lift 40' can receive the platform 100 located at the other end 11b of the second base 12 on the second layer 42', and can lift the received platform 100 to the first layer 41', which is connected to one end 11a of the first base 11.

[0106] According to this embodiment, the stage 100 can transport the solar cell C and the wires w disposed on the solar cell C to the curing zone Z6. The stage 100 can enter the curing zone Z6 through the first track L1 formed on opposite sides of the first base 11, and can also leave the curing zone Z6 through the first track L1. Here, multiple stages 100 can be continuously supplied to the curing zone Z6 while connected to each other.

[0107] Before entering the curing zone Z6, the stage 100 can be supplied to the first base 11 by the second stage lift 40'.

[0108] The first base 11 of the transport stage 100 is formed in an elongated shape, allowing the stage 100 to move into the curing area Z6 on the first base 11. A guide G is formed at the lower end of the stage 100, which is connected to a first track L1 formed on the first base 10 and allows the stage 100 to move along the first track L1.

[0109] The stage 100 on the first base 11 can be transported while it is mounted on the guide rod SH. Here, heat can be transferred to the solar cell C mounted on the stage 100 through the heater H provided inside the guide rod SH.

[0110] While maintaining connections to each other on multiple platforms 100, wires w are alternately positioned on the upper and lower surfaces of each of the solar cells C arranged in a row and in contact with each other.

[0111] When the stage 100 supplying the solar cell C and the wire w enters the curing zone Z6, the solar cell C and the wire w placed on the stage 100 can be cured. The stage 100 with the solar cell C that has undergone curing can be transported to the first layer 41 and placed on the first stage elevator 40 located on the first layer 41.

[0112] According to this embodiment, the solar cell manufacturing apparatus may further include a battery conveyor 50 connected to the first platform elevator 40. (See also...) Figure 10 The battery conveyor 50 is connected to the first layer 41 and can separate the solar cell C from the platform 100 on the first platform elevator 40 to transport the separate solar cell individually. The solar cell C transported by the battery conveyor 50 can be in a state of being connected to the wire w after the curing process of the wire and the solar cell C is completed.

[0113] According to this embodiment, the solar cell manufacturing apparatus may further include a pushing unit 60 connected to the first platform elevator 40. The pushing unit 60 can push the platform 100, which has been transported to the second layer 42 by the first platform elevator 40, toward the other end 12b of the second base 12.

[0114] The pushing unit 60 can push the platform 100, which is positioned on the first platform elevator 40 placed on the second layer 42. Here, the pushing unit 60 can push the platform 100 by one pitch P. After being pushed by one pitch P, the platform 100 can move to one end 12a of the second base 12.

[0115] Whenever a platform 100 is supplied to the second layer 42, the pushing unit 60 can push the platform 100 to one end 12a of the second base 12. The platform 100 pushed to one end 12a of the second base 12 can push the plurality of platforms 100 arranged in contact with each other on the second base 12 toward the other end 12b of the second base 12.

[0116] Therefore, when the pushing unit 60 pushes the platform 100 on the second layer 42 toward the other end 12b of the second base 12, the platform 100 closest to the other end 12b of the second base 12 among the plurality of platforms 100 provided on the second base 12 can be sequentially transported to the second layer 42' of the second platform elevator 40' under the pressure from the pushing unit 60.

[0117] On the first base 11 and the second base 12, multiple platforms 100 can be transported in contact with each other. (Refer to...) Figure 9Each of the platforms 100, 100', and 100'' may have a magnetic component M1, M1', and M1'' at one end and a steel component S1, S1', and S1'' at the other end, such that the magnetic component M1, M1', and M1'' at one end of one of the platforms 100, 100', and 100'' can be transported in a state of magnetic coupling with the steel component S1, S1', and S1'' at the other end of another platform adjacent to one platform.

[0118] Since the magnetic component comprises a magnet and the steel component comprises metal, and the magnetic component and the steel component are magnetically joined to each other, multiple platforms can be transported in contact with each other simply by placing the magnetic component and the steel component at their corresponding positions on each platform in the platform. This structure allows multiple platforms to be transported without any gaps between them, even without using separate devices, thereby enabling the constant and continuous cyclic transport of multiple platforms on the first and second bases.

[0119] According to this embodiment, such as Figure 10 As shown, the first platform lift 40 may include a first lifting frame 43 adapted to raise or lower the first platform lift 40, wherein the first lifting frame 43 may include a first guide member 43a for guiding the first platform lift 40 to move upward or downward. The first platform lift 40 may include a first sliding portion 40a slidably coupled to the first guide member 43a, such that the first sliding portion 40a can raise or lower the first platform lift 40 while sliding relative to the first guide member 43a.

[0120] On the platform 100 transported by the first platform lift 40, a solar cell C with wires attached can be coupled to a clamp J for fixing the solar cell C to the platform. According to this embodiment, a clamp retrieval unit 71 can be provided above the first platform lift 40 to detach and retrieve the clamp J from the platform 100 mounted on the first platform lift 40. Thus, the clamp J can be separated from the upper surface of the solar cell C.

[0121] The solar cell C, with the clamp J removed, can be transported separately from the stage 100 via the battery conveyor 50. The battery conveyor 50 may be provided with a battery support member 51. The battery conveyor 50 may have at least one battery support member 51 on one side. The battery support member 51 may have a strip shape extending from one side of the battery conveyor 50 toward the first heater H1 and the second heater H2.

[0122] The battery support 51 can be disposed in the area corresponding to the first platform lift 40. Specifically, for ease of description, although in Figure 10The battery support 51 is shown as being disposed in a region not perpendicular to the first platform lift 40, but it should be understood that the battery support 51 may be disposed in a region that overlaps with the first platform lift 40 in the vertical direction.

[0123] A battery support 51 can be disposed between the solar cell C and the platform 100. Specifically, the platform 100 and the solar cell C on the platform 100 can be conveyed to the area corresponding to the first platform lift 40. Furthermore, during the conveying process, the battery support 51 can be inserted into the area between the solar cell C and the platform 100 where the solar cell C is to be placed. The battery support 51 can be configured to support the lower surface of the solar cell C so that when the solar cell C is separated from the platform 100 and conveyed to the battery conveyor 50, the solar cell C can be safely conveyed to the battery conveyor 50 without falling downwards.

[0124] The cutting unit Cu can be positioned above the battery conveyor 50. The cutting unit Cu can cut the portion of the wire connecting the solar cells to the solar cells. Here, multiple solar cells constitute a solar cell module, and the cutting unit Cu can cut the portion of the wire connecting one solar cell module to another between two solar cell modules.

[0125] According to this embodiment, such as Figure 11 As shown, the second platform lift 40' may include a second lifting frame 43' adapted to raise or lower the second platform lift 40', wherein the second lifting frame 43' may include a second guide 43a' for guiding the second platform lift 40' to move upward or downward. The second platform lift 40' may include a second sliding portion 40a' slidably coupled to the second guide 43a', such that the second sliding portion 40a' can raise or lower the second platform lift 40' while sliding relative to the second guide 43a'.

[0126] According to this embodiment, such as Figure 4 and Figure 12As shown, the first base 11 and the second base 12 respectively include a first track L1 and a second track L2, and the platform 100 disposed on the first base 11 and the second base 12 is transported along the first track L1 and the second track L2. The first platform lift 40 may include a first additional track L1', which is connected to the first track L1 when the first platform lift 40 moves upward and is connected to the second track L2 when the first platform lift 40 moves downward. The second platform lift 40' may include a second additional track L2', which is connected to the first track L1 when the second platform lift 40' moves upward and is connected to the second track L2 when the second platform lift 40' moves downward.

[0127] Therefore, the plurality of platforms 100 on the first base 11 and the second base 12 can move naturally between the following via the guide G formed at the lower end of each of the platforms 100: between the first track L1 and the first additional track L1', between the first track L1 and the second additional track L2', between the second track L2 and the first additional track L1', between the second track L2 and the first additional track L1', and between the second track L2 and the second additional track L2'.

[0128] Next, refer to Figure 17 This describes a method for manufacturing a solar cell according to one embodiment of the present invention. Figure 17 For details and descriptions of components not shown in the diagram, please refer to [reference needed]. Figures 1 to 12 The details and descriptions shown in the figure.

[0129] Figure 17 This is a flowchart illustrating a method for manufacturing a solar cell according to an embodiment of the present invention.

[0130] Reference Figure 17 According to an embodiment of the present invention, the solar cell manufacturing method can be performed simultaneously with the stage 100 moving a preset pitch P. For example, when the stage 100 is supplied to move the preset pitch P, a wire w, a solar cell C, and a clamp J can be provided on the stage 100 so that processes such as heating, curing, and unloading can be performed sequentially.

[0131] The solar cell manufacturing method according to the embodiment may include the following steps: supplying a stage (S100); supplying wires to the stage (S200); supplying the solar cell and fixture to the stage (S300); preheating the solar cell and fixture (S400); curing the solar cell and fixture (S500); and removing the solar cell (S800).

[0132] Additionally, the step of supplying the platform (S100) can refer to the step of supplying the platform. For example, step S100 can refer to the step of raising the platform feeder 40 to supply the platform 100 to the platform supply area Z2. The platform 100 supplied in the platform supply step S100 can be conveyed one pitch P at a time according to the processing sequence.

[0133] The step of supplying wires to the platform (S200) can be performed after the supply platform (S100). The step of supplying wires to the platform (S200) can be the step of guiding the wire feeder 30 to supply wire w onto the platform 100. For example, step S200 can refer to the step of supplying wires onto the platform 100 placed in the solar cell placement area Z3 and the clamp fixing area Z4. Specifically, in step S200, the wire feeder 30 can extend the wire w to the platform supply area Z2, the solar cell placement area Z3, and the clamp fixing area Z4 via a clamp. Here, the extended wire w can be guided by a wire groove formed on the platform 100.

[0134] The step of supplying the solar cell and the fixture to the platform (S300) can be performed after the step of supplying the wires to the platform (S200). Step S300, supplying the solar cell and the fixture to the platform, can refer to the step of supplying the solar cell C and the fixture J to the platform 100 on which the wires w are provided. For example, step S300 can refer to the step of supplying the solar cell C to the platform 100 provided in the solar cell placement area Z3, and the step of supplying the fixture J to the platform 100 provided in the fixture fixing area Z4. In step S300, the solar cell C and the fixture J can be simultaneously supplied to the corresponding areas by the battery fixture conveying unit 91. Furthermore, the wires w provided on the solar cell C can be fixed to the solar cell C by the fixture J supplied in step S300. That is, it can be done as follows... Figure 2 As shown in (e), the wire w1, the solar cell C, the wire w2 and the clamp can be sequentially arranged on the stage 100 in the clamp fixing area Z4.

[0135] A preheating step (S400) can be performed after the step of supplying the solar cell and fixture onto the stage (S300). The preheating step (S400) can refer to the step of preheating the solar cell C and wire w disposed on the stage 100 by a first heater H1 in the preheating zone Z5. For example, as... Figure 2As shown in (f), in step S400, the solar cell C and the lower conductor w1 and upper conductor w2 respectively disposed on the upper and lower surfaces of the solar cell C can be preheated by the first heater H1 in the preheating zone Z5. Here, the first heater H1 can be disposed on the upper surface of the base 10, which transports and supports the aforementioned stage 100.

[0136] A curing step (S500) of the solar cell and fixture can be performed after the preheating step (S400) of the solar cell and fixture. The curing step (S500) can refer to the curing of the solar cell C and the wire w disposed on the stage 100 by the first heater H1 and the second heater H2 in the curing zone Z6. For example, in step S500, the solar cell C and the lower wire w1 and upper wire w2 disposed on the upper and lower surfaces of the solar cell C, respectively, can be cured in the curing zone Z6 by the first heater H1 and the second heater H2. Here, the second heater H2 can be disposed inside the curing unit 20 disposed above the base 10. The stage 100 can be transported between the first heater H1 and the second heater H2. Through step S500, the conductive adhesive (ECA) deposited on the upper and lower surfaces of the solar cell C can be cured, thereby allowing the wires w1 and w2 disposed on the upper and lower surfaces of the solar cell C to be physically and electrically connected to the solar cell C.

[0137] The step of removing the solar cell (S800) can be performed after the step of curing the solar cell and the fixture (S500). In step S800, the solar cell C connected to the upper and lower surfaces of the solar cell C by wires w1 and w2 can be removed. For example, the solar cell C connected to the solar cell C by wires w1 and w2 can be separated from the stage 100 and removed by the battery delivery unit 50.

[0138] The solar cell manufacturing method according to an embodiment of the present invention may further include a step of post-heating the solar cell and the fixture (S510). The step of post-heating the solar cell and the fixture (S510) can be performed between the step of curing the solar cell and the fixture (S500) and the step of removing the solar cell (S800). For example, step S510 may refer to the step of post-heating the solar cell C that has left the curing unit 20 after the curing step S500 in the exit zone Z7 using a first heater H1. Step S510 can act as a buffer step by slowly lowering the temperature of the solar cell C that has left the curing unit 20 in the exit zone Z7. Step S510 can prevent the cured solar cell C from experiencing sudden temperature changes, thereby further improving the quality of the solar cell C.

[0139] The solar cell manufacturing method according to an embodiment of the present invention may further include a step of retrieving the fixture (S600). The step of retrieving the fixture (S600) may be performed between the step of curing the solar cell and the fixture (S500) and the step of removing the solar cell (S800). For example, step S600 may refer to the step of retrieving the fixture J placed on the stage 100 after the stage 100 has passed through the curing zone Z6 and the exit zone Z7. Specifically, in step S600, the fixture J disposed on the stage 100 recycling unit 40' can be separated from the stage 100 and the solar cell C and retrieved by the fixture recycling unit 71. Alternatively, step S600 may refer to the step of retrieving the fixture J disposed in a fixture recycling area (not shown), which is located between the exit zone Z7 and the stage recycling unit 40'. Here, the fixture recycling unit 71 may be located in an area corresponding to the fixture recycling area.

[0140] The solar cell manufacturing method according to an embodiment of the present invention may further include a step of recycling the platform (S700). The step of recycling the platform (S700) can be performed between the step of curing the solar cell and the fixture (S500) and the step of removing the solar cell (S800). For example, step S700 may refer to the step of recycling the platform 100 that has passed through the curing zone Z6 and the exit zone Z7. Specifically, in step S700, the platform 100 can be recycled by the platform recycling unit 40'. The platform recycling unit 40' is connected to the platform feeder 40, and the platform 100 recycled by the platform recycling unit 40' can be conveyed to the platform feeder 40. The platform feeder 40 can then resupply the conveyed platform 100 to the platform supply zone Z2.

[0141] Therefore, as the stage 100 moves sequentially through the stage supply area Z2, the solar cell placement area Z3, the fixture fixing area Z4, the preheating area Z5, the curing area Z6, and the exit area Z7, the preparation and execution of the curing process for the solar cell C can be performed sequentially.

[0142] In other words, the steps of supplying wires w to the stage 100, placing the solar cell C on the stage 100, placing wires w on both surfaces of the solar cell C, and pressing the wires w placed on the upper surface of the solar cell C by the clamp J are performed sequentially. Then, after the step of preheating the solar cell C by the first heater H1, the stage 100 on which the solar cell C is placed (where the wires are placed on the solar cell C) enters the curing zone Z6 defined by the curing unit 20 and undergoes curing treatment in the curing zone Z6, thereby enabling the curing treatment to be performed systematically and stably.

[0143] Furthermore, after the curing process is complete, the solar cell C, which is conveyed from the curing zone Z6, undergoes post-heating in the exit zone Z7 to prevent deformation or damage due to sudden temperature changes when conveying the solar cell C from a high-temperature environment to a low-temperature environment. Additionally, after the curing process is complete, the platform and fixtures used to convey the solar cell can be recycled and resupplyed, enabling component recycling.

[0144] Next, refer to Figures 13 to 16 as well as Figure 18 This describes a method for manufacturing solar cells in a stage cycle according to an embodiment of the present invention. Figures 13 to 16 as well as Figure 18 For details and descriptions of components not shown in the diagram, please refer to [reference needed]. Figures 1 to 12 The details and descriptions shown in the figure.

[0145] Figure 13 This shows the stage on the first base along... Figure 8 The first direction in the diagram is the transport from one end to the other. Figure 14 It is shown Figure 13 The platform is transported to one end of the second base by the first platform elevator. Figure 15 It is shown Figure 14 The diagram shows the platform being pushed toward the other end of the second base by a pushing unit that is to be transported to the other end of the second base. Figure 16 It is shown Figure 15 The platform is transported to one end of the first base by the second platform elevator. Figure 17 This is a flowchart illustrating a method for manufacturing a solar cell according to an embodiment of the present invention. Figure 18 This is a flowchart illustrating a method for manufacturing a solar cell in a stage cycle according to an embodiment of the present invention.

[0146] Reference Figures 13 to 16 as well as Figure 18 The solar cell manufacturing method according to an embodiment of the present invention may further include a step of recycling the stage (S700). For example, the solar cell C may be placed on the stage 100, and the stage 100 may be transported along a first direction X from one end 11a of the first base 11 to the other end 11b of the first base 11, and the stage 100 disposed at the position corresponding to step S700 may be recycled in step S700.

[0147] The step of recycling the platform (S700) may include the following steps: separating the platform from the solar cell (S710); transporting the platform from the first layer to the second layer (S730); transporting the platform to the other end of the second base (S750); and transporting the platform from the second layer to the first layer (S770).

[0148] The step of separating the platform from the solar cell (S710) can refer to the step of separating the platform 100 and the solar cell C from each other by means of the battery conveyor 50. For example, step S710 can refer to the step of separating the solar cell C from the platform 100 by means of the battery support member 51 provided between the solar cell C and the platform 100. The step of separating the platform from the solar cell (S710) can be performed at a position corresponding to the first platform lift 40.

[0149] The step of transporting the platform from the first layer to the second layer (S730) can be performed after the step of separating the platform from the solar cell (S710). The step of transporting the platform from the first layer to the second layer (S730) can refer to the step of transporting the platform 100 on the first platform lift 40 from the first layer where the first base 11 is provided to the second layer where the second base 12 is provided, below the first layer. In step S730, the platform 100 can be transported from the first layer 31 to the second layer 32 connected to one end 12a of the second base 12 via the first platform lift 40.

[0150] The step of transporting the platform to the other end of the second base (S750) can be performed after the step of transporting the platform from the first layer to the second layer (S730). In step S750, the pushing unit 60 can push the platform 100 disposed on the second layer 42. Specifically, the pushing unit 60 can push the platform 100 disposed on the first platform elevator 40 located on the second layer 42 by one pitch P. The platform 100, pushed by one pitch, can be transported from one end 12a of the second base 12 toward the other end 12b of the second base 12.

[0151] The step of transporting the platform from the second layer to the first layer (S770) can be performed after the step of transporting the platform to the other end of the second base (S750). The step of transporting the platform from the second layer to the first layer (S770) can refer to the step of transporting the platform 100 disposed on the second platform elevator 40' from the second layer where the second base 12 is disposed to the first layer where the first base 11 is disposed. In step S770, the platform 100 can be transported by the second platform elevator 40' from the second layer 32 to the first layer 31 connected to one end 11a of the first base 11, such as the platform supply area Z2.

[0152] In the platform recovery step (S700), the platform 100, which is resupplying to the platform supply area Z2, can move sequentially through the solar cell mounting area Z3, the clamp fixing area Z4, the preheating area Z5, the curing area Z6 and the outlet area Z7 to undergo the aforementioned processing, and can be recovered again at the position corresponding to the first platform elevator 40.

[0153] In other words, as in this embodiment, the platform 100 transported on the first base 11 and the second base 12 arranged vertically can circulate from the first base 11 to the second base 12 and from the second base 12 to the first base 11, and from the second base 12 to the first base 11, as well as through the first platform lift 40 and the second platform lift 40' arranged vertically and connecting the first base 11 and the second base 12 to each other at both ends.

[0154] Thus, in the curing process where the wires are bonded to the solar cell while it is placed on the stage, the solar cell undergoing the curing process is separated from the stage and supplied separately, while the solar cell requiring curing can be repositioned on the circulating stage, thereby allowing the curing process to be performed continuously.
