Description

Technical Field

[0001] Embodiments of the present invention relate to a solar cell manufacturing apparatus and a solar cell manufacturing method. Background Art

[0002] A solar cell (i.e., a solar battery) is formed by arranging diodes formed by a pn junction on a substrate. When sunlight shines on the solar cell, excitons, which are electron-hole pairs, are generated. When the excitons separate, the electrons move to the n-layer and the holes to the p-layer, generating photovoltaic power at the pn junction. Tabbing is a process that electrically connects multiple solar cells by arranging wires across them to form a single solar cell module.

[0003] In this case, as a process of coupling the solar cell and the wire, there is a process of coating the surface of the solar cell with an electrically conductive adhesive (ECA) and then coupling the wire to the solar cell.

[0004] In the case of a process of coupling a solar cell and a wire using a conductive adhesive, various studies are being conducted on specific examples of a next-generation solar cell manufacturing process. Summary of the Invention

[0010] The solar cell manufacturing equipment may further include: a first conveyor configured to transfer the solar cell whose first surface is coated by the first dispenser to the position where the flip part is located; and a second conveyor configured to transfer the solar cell flipped by the flip part to the position where the second dispenser is located.

[0011] The first flip part may be coupled to the second surface of the solar cell through the first protrusion and the first adsorption part, and when the main body is rotated, the first flip part may be separated from the solar cell and seat the solar cell on the second conveyor.

[0012] The second conveyor may further include a protruding conveyor formed to protrude from a surface of the second conveyor, and a width of the protruding conveyor may be smaller than a width of the second conveyor.

[0013] An upper surface of the first conveyor and an upper surface of the protruding conveyor may be positioned on a horizontal line (L).

[0014] The solar cell manufacturing apparatus may further include a heat treatment zone configured to allow the solar cell to be coupled to the wire through the second dispenser.

[0015] The first protrusion may be formed as a plurality of first protrusions that contact a plurality of portions of the solar cell.

[0016] The first protrusion is formed as four protrusions, and the four protrusions may be symmetrically disposed at four positions centered on the first adsorption portion.

[0017] The end portion of the first protrusion may be formed as a new member.

[0018] The first dispenser may apply the conductive adhesive on a first surface of the solar cell positioned below the first dispenser, and the second dispenser may apply the conductive adhesive on a second surface of the solar cell positioned below the second dispenser.

[0019] The first flip portion may be formed as one or more first flip portions.

[0020] The first flip parts may be formed at both sides with respect to the main body, and when the main body is rotated, the two first flip parts may alternately flip the solar cell.

[0021] According to one embodiment of the present invention, a method for manufacturing a solar cell includes: transferring a solar cell to a position where a first dispenser is located; coating a first surface of the solar cell with a conductive adhesive by the first dispenser; transferring the solar cell with the conductive adhesive coated on the first surface to a flipping part by a first conveyor; flipping the solar cell by the flipping part; transferring the flipped solar cell to a position where a second dispenser is located; and coating a second surface of the solar cell with a conductive adhesive by the second dispenser.

[0022] Flipping the solar cell by the flipping part may include: connecting the first flipping part to the second surface of the solar cell through the first protrusion and the first adsorption part of the first flipping part; rotating the main body of the first flipping part; and separating the first flipping part from the solar cell, and placing the solar cell on the second conveyor in a flipped state.

[0023] The solar cell manufacturing method may further include moving the solar cell, the first and second surfaces of which are coated with the conductive adhesive, to a heat treatment zone, and performing a wire bonding process.

[0026] In the solar cell manufacturing apparatus and the solar cell manufacturing method according to one embodiment of the present invention, both the front and rear surfaces of the solar cell may be coated by the dispenser and the turning portion that turns over the solar cell.

[0027] In addition, in the solar cell manufacturing apparatus and solar cell manufacturing method according to one embodiment of the present invention, both the first dispenser and the second dispenser can coat the solar cell from top to bottom, without having to coat the solar cell from above and below to coat both surfaces of the solar cell. Therefore, when coating both surfaces of the solar cell, the conditions of the two dispensers can be set to the same. Therefore, the application device can be simplified, and the two dispensers can be formed with the same specifications to be interchangeable with each other, thereby improving convenience.

[0028] Furthermore, in the solar cell manufacturing apparatus and the solar cell manufacturing method according to one embodiment of the present invention, when coating the second surface of the solar cell, a narrow protruding conveyor is additionally provided to minimize contact with the conductive adhesive already applied on the first surface.

[0029] In addition, in the solar cell manufacturing apparatus and the solar cell manufacturing method according to one embodiment of the present invention, a new member is applied as a protruding end member that contacts the surface of the solar cell, thereby protecting the surface of the solar cell and preventing material from being torn or peeled off from the surface of the solar cell.

[0030] In addition, in the solar cell manufacturing apparatus and the solar cell manufacturing method according to one embodiment of the present invention, the total available cycle (TAC) time can be shortened by newly forming a heat treatment area for connecting wires and coated solar cells after completing coating of the front and rear surfaces of the solar cell.

[0031] The effects of the present invention are not limited to those described above, and other effects that are not described will be clearly understood by those of ordinary skill in the art based on the description of the claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In the following, reference will be made to Figures 1 to 6 A solar cell manufacturing apparatus according to one embodiment of the present invention will be described.

Figure 3 is a side view showing in more detail the configuration around the turning portion of the solar cell manufacturing apparatus according to one embodiment of the present invention. Figure 4 is a view illustrating a configuration of a first protrusion and a first adsorption portion of a first reversal portion according to one embodiment of the present invention. Figure 5 FIG. 1 is a top view showing a flip portion and its surrounding configuration in more detail according to one embodiment of the present invention. Figure 6 is shown in more detail Figure 3 A side view of a configuration around a turning portion of a solar cell manufacturing apparatus including a conveyor.

[0049] refer to Figures 1 to 6 According to one embodiment of the present invention, a solar cell manufacturing apparatus includes a first dispenser 210 for applying a conductive adhesive to a first surface C1 of a solar cell C, a reversing portion 100 for reversing the solar cell C, and a second dispenser 220 for applying the conductive adhesive to a second surface C2 of the solar cell C. In this case, the reversing portion 100 includes a rotating body 120 and a first reversing portion 110 coupled to one side of the body 120, and the first reversing portion 110 includes a first protrusion 112 formed so that an end portion 112a protrudes to contact the solar cell, and a first adsorption portion 111 that adsorbs the solar cell C in a direction in which the reversing portion is positioned.

[0050] The solar cells C can be transferred by the first conveyor 300 to the location of the first dispenser 210, specifically, to the space below the first dispenser 210. In this case, the transferred solar cells C can be in a state where the first surface C1 faces upward. In the solar cells C transferred by the first conveyor 300 to the space below the first dispenser 210, a conductive adhesive can be applied to the first surface C1 by the first dispenser 210. In this case, the first dispenser 210 can perform a coating process on the solar cells C positioned in the space below the first dispenser 210 in the direction of gravity.

[0051] The solar cell C whose first surface C1 has been completely coated can be transferred back to the position where the flipping part 100 is located by the first conveyor 300. In this case, the first flipping part 110 of the flipping part 100 can be disposed in the space below the solar cell C. In the first flipping part 110, in the space below the solar cell C, the first adsorption portion 111 and the first protrusion 112 can be formed to protrude toward the second surface C2 of the solar cell C.

[0052] The first adsorption portion 111 can adsorb the solar cell C in the direction in which the first flip portion 110 is positioned. The first adsorption portion 111 can be spaced apart from the solar cell C. In addition, the first protrusion 112 can be formed so that the end portion 112a protrudes to contact the solar cell. Therefore, when the first adsorption portion 111 adsorbs the second surface C2 of the solar cell C, the second surface C2 of the solar cell C can be spaced apart from the first adsorption portion 111 and can contact the first protrusion 112. Therefore, the contact area between the flip portion 100 and the solar cell C can be minimized, and the first protrusion 112 and the second surface C2 of the solar cell C can be in contact with each other by the suction force of the first adsorption portion 111 to maintain a state of being coupled to each other.

[0053] As an example, the first suction portion 111 can utilize the Bernoulli effect to suction the solar cell C in a non-contact manner. Specifically, the flip portion 100 can discharge compressed air to the edge region of the first suction portion 111, thereby forming a vacuum between the first suction portion 111 and the second surface C2 of the solar cell C. This allows the solar cell C to be suctioned in a non-contact manner using the negative pressure generated by the pressure difference. To this end, the first suction portion 111 may include a flow portion (not shown) that supplies compressed air to the solar cell C, and a guide portion (not shown) at the end of the flow portion that discharges the compressed air toward the edge region of the lower surface of the first suction portion 111 that faces the solar cell C.

[0054] After the first flip part 110 and the solar cell C are coupled to each other, the flip part 100 may be rotated. In this case, the first flip part 110 may be rotated around the body 120 of the flip part 100 together with the adsorbed and coupled solar cell C. The rotation may be performed at an angle of 180 degrees.

[0055] After the rotation of the flip part 100 is completed, the solar cell C may be positioned below the first flip part 110 ′. In this case, the upper surface of the solar cell C may become the second surface C2 , and the lower surface of the solar cell C may become the first surface C1 .

[0056] After completing the rotation of the flip portion 100 , the first flip portion 110 ′ may be separated from the solar cell C. In this case, when the operation of the first adsorption portion 111 ′ stops, the contact coupling between the first protrusion 112 ′ and the solar cell C may be spontaneously released.

[0057] At the same time, the solar cell C may be placed on the second conveyor 300'. According to the present embodiment, the second conveyor 300' may have a set width W1. For example, the width W1 of the second conveyor 300' may be less than or equal to the width W0 of the first conveyor 300. Therefore, damage to the conductive adhesive applied on one surface of the solar cell C by the second conveyor 300' may be prevented and / or minimized. In addition, the second conveyor 300' may include a protruding conveyor 310' formed to protrude from the surface of the second conveyor 300'. In this case, the width W2 of the protruding conveyor 310' may be less than the width W1 of the second conveyor 300'. For example, the width of the protruding conveyor 310' may be formed to be quite narrow to form an approximately linear shape.

[0058] The protruding conveyor 310 ′ may contact the surface of the solar cell C between the conductive adhesive applied portions of the surface of the solar cell C. Therefore, the protruding conveyor 310 ′ may support both sides of the solar cell C and simultaneously safely transfer the solar cell C to the location where the second dispenser 220 is located.

[0059] In the solar cell C flipped over by the flipping unit 100, the first surface C1 faces downward while being coated with the conductive adhesive. In this case, the first surface C1 inevitably contacts the surface of the second conveyor 300'. Therefore, as in this embodiment, by forming the protruding conveyor 310' additionally on the second conveyor 300', the contact area between the protruding conveyor 310' and the first surface C1 on which the conductive adhesive is applied is minimized, thereby minimizing damage to the surface of the solar cell on which the conductive adhesive is applied.

[0060] In this case, according to this embodiment, Figure 6 As shown in , the first conveyor 300 and the second conveyor 300' can be set at different levels. For example, the upper surface of the first conveyor 300 can be positioned at a higher level than the upper surface of the second conveyor 300' and closer to the solar cell C. In addition, the upper surface of the first conveyor 300 and the upper surface of the protruding conveyor 310' can be positioned on the horizontal line L. In the process of conveying the solar cell C from the first conveyor 300 to the second conveyor 300', by constantly maintaining the height at which the solar cell C is set, the distribution process of each of the first dispenser 210 and the second dispenser 220 can be set under the same conditions. Therefore, the two dispenser processes can be performed under the same structure and conditions, so that the manufacturing process of the dispenser device can be simplified, the interchangeability between the dispenser devices can be achieved, and the uniformity of the quality of the dispenser process can also be ensured.

[0061] In addition, since the first dispenser 210 applies the conductive adhesive on the first surface C1 of the solar cell C positioned below the first dispenser 210, and the second dispenser 220 applies the conductive adhesive on the second surface C2 of the solar cell C positioned below the second dispenser 220, there is no need to set a dispensing structure in the space below the solar cell C to coat both surfaces of the solar cell C with the conductive adhesive, and thus the two dispensers 210 and 220 can apply the conductive adhesive on both surfaces of the solar cell C under the same conditions.

[0062] The protruding conveyor 310' of the second conveyor 300' can transfer the solar cells C to the location of the second dispenser 220, specifically, to the space below the second dispenser 220. In this case, the transferred solar cells C can be in a state where the second surface C2 faces upward. In the solar cells C transferred to the space below the second dispenser 220 by the protruding conveyor 310', a conductive adhesive can be applied to the second surface C2 by the second dispenser 220. In this case, the second dispenser 220 can perform a coating process on the solar cells C positioned in the space below the second dispenser 220 in the direction of gravity.

[0063] According to this embodiment, solar cells C that have passed through the second dispenser 220 can be transferred to a heat treatment zone 400 for connecting the solar cells C to wires. Heat treatment zone 400 can dry the applied conductive adhesive (ECA) at a temperature of 50 to 250 degrees Celsius to maximize adhesion. In heat treatment zone 400, a process is performed to heat-treat and bond the solar cells C coated with the conductive adhesive to the wires. This newly formed heat treatment zone 400, which is used to cure and bond the wires formed in the solar cells to which the conductive adhesive has been applied, can shorten the total available cycle (TAC) for wire bonding.

[0064] According to this embodiment, a plurality of first protrusions 112 may be formed to contact a plurality of portions of the solar cell C. For example, Figure 4 As shown in FIG, four first protrusions 112 may be formed, and the four first protrusions 112 may be symmetrically disposed at four positions centered on the first adsorption portion 111 .

[0065] Since the first adsorption portion 111 is positioned at the center of a symmetrical point forming the four first protrusions 112 , the solar cells C may uniformly contact and be coupled to the four first protrusions 112 when the first adsorption portion 111 performs an adsorption operation.

[0066] In this case, the first adsorption portion 111 may be formed to have a predetermined gap G from the solar cell C, and the first protrusion 112 may be formed to protrude further from the surface of the first flip portion 110 than the first adsorption portion 111. The first adsorption portion 111 may draw air through the gap G.

[0067] Furthermore, since the first protrusions 112 symmetrically contact the surface of the solar cell C, the solar cell C can be evenly contacted and coupled to the four first protrusions 112 without being biased to one side. In this embodiment, four first protrusions 112 are formed, but the number and arrangement of the first protrusions 112 are not limited to this. As long as the number and arrangement of the first protrusions 112 are sufficient to stably flip the solar cell, various embodiments can be implemented.

[0068] According to this embodiment, the end portion 112a of the first protrusion 112 can be made of a material that has a predetermined frictional force when in contact with the solar cell C and does not damage the solar cell C. For example, the end portion 112a can include a resin material such as polyurethane resin. Therefore, when the end portion 112a contacts the surface of the solar cell C, it can prevent the surface material of the solar cell C from peeling or tearing (for example, tearing of the perovskite), thereby improving the defect rate. In addition, the end portion 112a can have a predetermined frictional force with the solar cell C, so that when the solar cell C is transferred, the solar cell C can be transferred to a predetermined position.

[0069] According to this embodiment, one or more first flip parts 110 may be formed. For example, the first flip parts 110 may be formed at 180 degrees on both sides relative to the body 120, and when the body 120 rotates, the two first flip parts 110 may alternately flip the solar cell C.

[0070] In this manner, the coating process of the solar cells C may be more densely performed through the structure in which the two first flip parts 100 are provided, thereby improving productivity.

[0071] In the following, reference Figure 7 , a method for manufacturing a solar cell according to an embodiment of the present invention will be described. Figure 7 For details not shown in Figures 1 to 6 .

[0072] Figure 7 is a flowchart illustrating a method for manufacturing a solar cell according to one embodiment of the present invention.

[0073] refer to Figure 7, a solar cell manufacturing method according to one embodiment of the present invention includes an operation S100 of transferring a solar cell to a position where a first dispenser is located, an operation S200 of coating a first surface of the solar cell with a conductive adhesive by the first dispenser, an operation S300 of transferring the solar cell whose first surface is coated with the conductive adhesive to a flipping part by a first conveyor, an operation S400 of flipping the solar cell by the flipping part, an operation S500 of transferring the flipped solar cell to a position where a second dispenser is located, and an operation S600 of coating a second surface of the solar cell with a conductive adhesive by the second dispenser.

[0074] In this case, the solar cell manufacturing method may further include operation S700 of moving the solar cell having the first and second surfaces coated with the conductive adhesive to a heat treatment zone and performing a wire bonding process.

[0075] In addition, the operation S400 of flipping the solar cell by the flipping part may include an operation S410 of connecting the first flipping part to the second surface of the solar cell through the first protrusion of the first flipping part and the first adsorption part of the flipping part, an operation S420 of rotating the main body of the flipping part, and an operation S430 of separating the first flipping part from the solar cell and placing the solar cell on a second conveyor in a flipped state.

[0076] Therefore, it is possible to ensure uniformity of quality in a process of coating solar cells with a conductive adhesive, shorten TAC time through optimization, and ensure productivity.
