Description
Technical Field
[0001] The present disclosure relates to the technical field of semiconductor or photovoltaic product manufacturing, and in particular to a conductive device and a laser-induced metallization device. Background Art
[0002] Solar cells include crystalline silicon cells and grid lines. The grid lines are made of metal materials and are spaced apart in the crystalline silicon cells. The metal-semiconductor contact resistance has a significant impact on the cell fill factor and conversion efficiency. The lower the metal-semiconductor contact resistance, the higher its conversion efficiency. At present, the main way to reduce the metal-semiconductor contact resistance is the Laser Enhanced Contact Optimization (LECO) process, also known as laser-assisted sintering process or laser-induced metallization process, which irradiates photovoltaic cells with high-intensity lasers to excite charge carriers, and applies a deflection voltage to the photovoltaic cells to separate the carriers, forming a local current, inducing sintering, and reducing the contact resistance between the metal and the semiconductor.
[0003] At present, the related technology uses multiple pressing pins to contact multiple gate lines respectively, and each pressing pin is connected to a wire, which is connected to a power supply to achieve electrical connection between the pressing pin and the crystalline silicon cell. However, due to the large number of wires and the complex circuit structure, the complex circuit limits the flexibility of the pressing pin's movement. During the movement of the pressing pin, the wire may exert a certain pulling force on the pressing pin. During the movement of the pressing pin toward the crystalline silicon cell, the pulling force will hinder the movement of the pressing pin, causing the pressing pin to jam during its movement toward the crystalline silicon cell, which in turn causes some pressing pins to fail to contact the gate lines, resulting in the failure of the pressing pin to conduct electricity.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0030] Solar cells include crystalline silicon sheet materials and grid lines. The grid lines are made of metal materials and are spaced apart in the crystalline silicon sheet materials. The metal-semiconductor contact resistance has a significant impact on the cell fill factor and conversion efficiency. The lower the metal-semiconductor contact resistance, the higher its conversion efficiency, and the conversion efficiency represents the performance of the cell. Therefore, reducing the metal-semiconductor contact resistance is a difficult problem that needs to be overcome in the preparation of high-efficiency crystalline silicon solar cells.
[0031] At present, the main way to reduce the metal-semiconductor contact resistance is the Laser Enhanced Contact Optimization (LECO) process, also known as laser-assisted sintering or laser-induced metallization. It irradiates photovoltaic cells with high-intensity lasers to excite charge carriers, and applies a deflection voltage to the photovoltaic cells to separate the carriers, forming a local current and inducing sintering to reduce the contact resistance between the metal and the semiconductor.
[0032] At present, the related technology uses multiple pressing pins to contact multiple gate lines respectively, and each pressing pin is connected to a wire, which is connected to a power supply to achieve electrical connection between the pressing pin and the crystalline silicon cell. However, due to the large number of wires and the complex circuit structure, the complex circuit limits the flexibility of the pressing pin's movement. During the movement of the pressing pin, the wire may exert a certain pulling force on the pressing pin. During the movement of the pressing pin toward the crystalline silicon cell, the pulling force will hinder the movement of the pressing pin, causing the pressing pin to jam during its movement toward the crystalline silicon cell, which in turn causes some pressing pins to fail to contact the gate lines, resulting in the failure of the pressing pin to conduct electricity.
[0033] In response to the above problems, an embodiment of the present disclosure provides a conductive device, which is applied to a laser induced metallization device. The laser induced metallization device includes a driving component and a conductive device. The driving component is configured to drive the conductive device to move so that the conductive device is electrically connected to the sheet material. The conductive device includes: a mounting component, a plurality of pressure needle assemblies and at least one conductive connector. The mounting component is connected to the driving component. The plurality of pressure needle assemblies are slidably connected to the mounting component and contact and press the sheet material or separate from the sheet material under the drive of the driving component. At least one conductive connector is installed on the mounting component and abuts against the pressure needle assembly so that the pressure needle assembly is electrically connected to the power supply through the conductive connector, and the pressure needle assembly can move relative to the conductive connector. In the process of the pressure needle assembly and the sheet material from contact to pressing, the pressure needle assembly and the conductive connector move frictionally. The conductive device realizes electrical connection between the pressing needle assembly and the power supply through the conductive connecting piece by abutting the pressing needle assembly with the conductive connecting piece, and the pressing needle assembly can move relative to the conductive connecting piece. In the process of the pressing needle assembly moving toward the sheet material, the movement of the pressing needle assembly is no longer subject to the pulling force of the wire, thereby avoiding the pressing needle assembly from getting stuck in the process of moving toward the sheet material, and further avoiding the pressing needle assembly from failing to contact the sheet material and conducting electricity.

[0038] Figure 1 Shown is a schematic structural diagram of a laser induced metallization device provided in one embodiment of the present disclosure. Figure 2 Shown is a schematic structural diagram of a conductive device and a sheet material provided in one embodiment of the present disclosure. Figure 3 FIG. 1 is a schematic diagram of the structure of a conductive device provided by an embodiment of the present disclosure. Figures 1 to 3 As shown, the conductive device 10 is applied to the laser induced metallization equipment 1, and the laser induced metallization equipment 1 includes a driving component 30 and a conductive device 10, and the driving component 30 is configured to drive the conductive device 10 to move so that the conductive device 10 is electrically connected to the sheet material 2. The conductive device 10 includes: a mounting component 100, a plurality of pressure needle components 200 and at least one conductive connector 400. The mounting component 100 is connected to the driving component 30, and the plurality of pressure needle components 200 are all slidably connected to the mounting component 100, and are in contact with and pressed against the sheet material 2 or separated from the sheet material 2 under the drive of the driving component 30. At least one conductive connector 400 is installed on the mounting component 100 and abuts against the pressure needle component 200, so that the pressure needle component 200 is electrically connected to a power source (not shown in the figure) through the conductive connector 400, and the pressure needle component 200 can move relative to the conductive connector 400. In the process from contact to pressing between the pressure needle component 200 and the sheet material 2, the pressure needle component 200 and the conductive connector 400 move frictionally.
[0039] The installation component 100 is fixedly connected to the driving component 30. The installation component 100 can be non-detachably connected to the driving component 30 by welding, bonding, etc., or the installation component 100 can be detachably connected to the driving component 30 by bolts, nuts, screws, snaps, magnetism, etc.
[0040] The conductive connector 400 is fixedly connected to the installation component 100. The conductive connector 400 can be non-detachably connected to the installation component 100 by welding, bonding, etc., or the conductive connector 400 can be detachably connected to the installation component 100 by bolts, nuts, screws, snaps, magnetism, etc.
[0041] For example, Figure 1 and Figure 3 As shown, the mounting assembly 100 is connected to the support frame 120 , the support frame 120 is connected to the driving assembly 30 , and the plurality of pressing needle assemblies 200 are all slidably connected to the mounting assembly 100 .
[0042] The support frame 120 is fixedly connected to the driving assembly 30. The support frame 120 can be non-detachably connected to the driving assembly 30 by welding, bonding, etc., or the support frame 120 can be detachably connected to the driving assembly 30 by bolts, nuts, screws, snaps, magnetism, etc.
[0043] The cross-sectional shape of the support frame 120 may be a rectangle, a trapezoid, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.
[0044] The shape of the needle pressing assembly 200 can be a long needle-shaped structure, and the cross-sectional shape of the needle pressing assembly 200 can be rectangular, circular, or other polygonal or irregular shapes. The shape of the needle pressing assembly 200 can also be an L-shaped structure or a special-shaped structure, which is not specifically limited in the present disclosure.
[0045] The sheet material 2 can be a product such as a silicon wafer, a battery panel, or a glass substrate.
[0046] Exemplarily, the sheet material 2 is a battery sheet, and the sheet material 2 has a plurality of grid lines 23 . Driven by the driving component 30 , the plurality of pressing needle components 200 contact and press or separate the plurality of grid lines 23 of the sheet material 2 .
[0047] Exemplarily, the conductive device 10 may include a conductive connector 400 , which is mounted on the mounting assembly 100 . The plurality of pressure pin assemblies 200 are all in contact with the conductive connector 400 , and the plurality of pressure pin assemblies 200 can move frictionally relative to the conductive connector 400 .
[0048] Exemplarily, the driving component 30 can drive the installation component 100 to move downward to drive the conductive connector 400 and the pressing needle component 200 to move downward. The pressing needle component 200 contacts the sheet material 2. The driving component 30 continues to drive the installation component 100 to move downward to drive the conductive connector 400 to continue to move downward. In the process from contact to compression between the pressing needle component 200 and the sheet material 2, the sheet material 2 generates a reaction force on the pressing needle component 200, so that the pressing needle component 200 slides upward relative to the installation component 100 and the conductive connector 400.
[0049] Exemplarily, the friction motion between the pressure pin assembly 200 and the conductive connector 400 may be a sliding friction motion or a rolling friction motion.
[0050] For example, when the friction movement between the pressing needle assembly 200 and the conductive connector 400 is a sliding friction movement, the conductive connector 400 can directly abut against the surface of the pressing needle assembly 200, and in the process from contact to compression between the pressing needle assembly 200 and the sheet material 2, the conductive connector 400 and the surface of the pressing needle assembly 200 frictionally slide.
[0051] For another example, when the friction movement between the pressing needle assembly 200 and the conductive connector 400 is a sliding friction movement, a first sliding groove may be provided on the side of the pressing needle assembly 200 facing the conductive connector 400, and the conductive connector 400 abuts against the bottom of the first sliding groove. In the process of the pressing needle assembly 200 and the sheet material 2 going from contact to compression, the conductive connector 400 slides in the first sliding groove.
[0052] For another example, when the friction movement between the pressing needle assembly 200 and the conductive connector 400 is a sliding friction movement, a second slide groove may be provided on the side of the conductive connector 400 facing the pressing needle assembly 200, and the pressing needle assembly 200 abuts against the bottom of the second slide groove. In the process from contact to compression between the pressing needle assembly 200 and the sheet material 2, the pressing needle assembly 200 slides in the second slide groove.
[0053] For another example, when the friction movement between the pressing needle assembly 200 and the conductive connector 400 is a rolling friction movement, a first roller may be provided on the side of the pressing needle assembly 200 facing the conductive connector 400, and the conductive connector 400 abuts against the first roller. In the process of the pressing needle assembly 200 and the sheet material 2 going from contact to compression, the first roller rolls relative to the conductive connector 400.
[0054] For another example, when the friction movement between the pressing needle assembly 200 and the conductive connector 400 is a rolling friction movement, a second roller may be provided on the side of the conductive connector 400 facing the pressing needle assembly 200, and the pressing needle assembly 200 abuts against the second roller. In the process of the pressing needle assembly 200 and the sheet material 2 going from contact to compression, the second roller rolls relative to the pressing needle assembly 200.
[0055] In the related art, each pressing needle assembly 200 is electrically connected to the power supply through a wire, resulting in a large number of wires and a complex circuit structure. When the pressing needle assembly 200 approaches the sheet material 2, the wire may generate a certain pulling force on the pressing needle assembly 200. The pulling force may be a force along the movement direction of the pressing needle assembly 200, or a force along a direction intersecting with the movement direction of the pressing needle assembly 200. In the case where the pulling force is a force along a direction intersecting with the movement direction of the pressing needle assembly 200, the pulling force will cause the pressing needle assembly 200 to be unable to continue to move, resulting in the pressing needle assembly 200 being unable to slide upward relative to the mounting assembly 100 and the conductive connector 400 during the process from contact to compression between the pressing needle assembly 200 and the sheet material 2, thereby causing the pressing needle assembly 200 to continue to move toward the sheet material 2 following the mounting assembly 100, and further causing the pressing needle assembly 200 to crush the sheet material 2 or cause hidden cracks in the sheet material 2.
[0056] The conductive device 10 provided in the embodiment of the present disclosure realizes that the pressing needle assembly 200 is electrically connected to the power supply through the conductive connecting piece 400 by abutting against the pressing needle assembly 200 and the conductive connecting piece 400, and the pressing needle assembly 200 can move relative to the conductive connecting piece 400. In the process of the pressing needle assembly 200 moving toward the sheet material 2, the movement of the pressing needle assembly 200 is no longer subject to the pulling force of the wire, thereby avoiding the pressing needle assembly 200 from getting stuck in the process of moving toward the sheet material 2, and further avoiding the pressing needle assembly 200 failing to contact the sheet material 2 and conducting electricity.
[0057] In addition, since the movement of the pressing needle assembly 200 is no longer subject to the tension of the wire, in the process from contact to compression between the pressing needle assembly 200 and the sheet material 2, the pressing needle assembly 200 can slide upward relative to the mounting assembly 100 and the conductive connector 400, thereby ensuring that the pressing needle assembly 200 does not apply excessive compression force to the sheet material 2, thereby preventing the pressing needle assembly 200 from crushing the sheet material 2 or causing hidden cracks in the sheet material 2.
[0058] In some embodiments, Figure 3 and Figure 4 As shown, a sliding plane 201 is provided on one side of the pressing needle assembly 200 facing the conductive connecting member 400 , and the conductive connecting member 400 abuts against the sliding plane 201 , so that the conductive connecting member 400 and the pressing needle assembly 200 are slidably connected.
[0059] In some embodiments, the conductive connector 400 includes a first elastic member 410, which is mounted on the mounting assembly 100 and abuts against the pressing needle assembly 200. When the pressing needle assembly 200 contacts the sheet material 2 and generates a tipping force, the first elastic member 410 applies a force opposite to the tipping force to the pressing needle assembly 200, and the first elastic member 410 buffers the tipping of the pressing needle assembly 200, and can also prevent the pressing needle assembly 200 from tipping and shifting.
[0060] The first elastic member 410 may be a spring, a rubber block, or other structures with elastic function, which is not specifically limited in the present disclosure.
[0061] In some embodiments, Figure 2 and Figure 5 As shown, the conductive connection assembly 400 further includes a conductive body 420 and a contact member 430. The conductive body 420 is mounted on the mounting assembly 100, and the conductive body 420 has a receiving cavity 4201, and the receiving cavity 4201 is configured to receive the first elastic member 410, and the first end 4301 of the contact member extends into the receiving cavity 4201 and is connected to the first elastic member 410, and the second end 4302 of the contact member is located outside the receiving cavity 4201 and abuts against the pressure needle assembly 200, and the contact member 430 can compress the first elastic member 410 when being squeezed by an external force.
[0062] The contact member 430 can be fixedly connected to the first elastic member 410. The contact member 430 can be non-detachably connected to the first elastic member 410 by welding, bonding, etc., or the contact member 430 can be detachably connected to the first elastic member 410 by bolts, nuts, screws, snaps, magnetism, etc.
[0063] In some embodiments, the number of conductive connectors 400 is the same as the number of press pin assemblies 200, and multiple conductive connectors 400 and multiple press pin assemblies 200 are arranged in abutment with each other in a one-to-one correspondence, which makes it easier to adjust the installation position of each conductive connector 400 for each press pin assembly 200, so that each conductive connector 400 abuts against each press pin assembly 200, so as to further ensure that each press pin assembly 200 is electrically connected to the power supply via each conductive connector 400. The installation assembly 100 also includes: an installation body 110 and a conductive member 300, and the installation body 110 is connected to the driving assembly 30. The conductive member 300 is installed on the installation body 110, and all the conductive connectors 400 are installed on the conductive member 300, and the conductive member 300 is used to be electrically connected to the power supply, so that the press pin assembly 200 is electrically connected to the power supply via the conductive connector 400 and the conductive member 300.
[0064] Exemplarily, when the conductive connection assembly 400 is connected to the conductive member 300 and abuts against the press pin assembly 200 , the conductive body 420 is connected to the conductive member 300 , and the second end 4302 of the contact member abuts against the press pin assembly 200 .
[0065] For example, Figure 1 , Figure 3 and Figure 4 As shown, the installation body 110 is connected to the support frame 120 , the support frame 120 is connected to the driving assembly 30 , and the plurality of pressing needle assemblies 200 are all slidably connected to the installation body 110 .
[0066] The installation body 110 is fixedly connected to the support frame 120. The installation body 110 can be non-detachably connected to the support frame 120 by welding, bonding, etc., or the installation body 110 can be detachably connected to the support frame 120 by bolts, nuts, screws, snaps, magnetism, etc.
[0067] The conductive member 300 is fixedly connected to the installation body 110. The conductive member 300 can be non-detachably connected to the installation body 110 by welding, bonding, etc., or the conductive member 300 can be detachably connected to the installation body 110 by bolts, nuts, screws, snaps, magnetism, etc.
[0068] The conductive connector 400 is fixedly connected to the conductive component 300. The conductive connector 400 can be non-detachably connected to the conductive component 300 by welding, bonding, etc., or the conductive connector 400 can be detachably connected to the conductive component 300 by bolts, nuts, screws, snaps, magnetism, etc.

[0070] The conductive member 300 may be made of metal, such as copper, aluminum, iron, etc. The conductive member 300 may be in the shape of a long strip, and the cross-sectional shape of the conductive member 300 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which are not specifically limited in the present disclosure.
[0071] In some embodiments, Figure 3 As shown, the conductive member 300 is in the shape of a long strip, and the conductive device 10 further includes at least one conductive wire 500 , and the at least one conductive wire 500 connects the conductive member 300 and a power source.
[0072] In the case where there is one wire 500, the wire 500 is connected to the middle of the conductive member 300 to apply voltage to the middle of the conductive member 300; in the case where there are two wires 500, the two wires 500 are respectively connected to the two ends of the conductive member 300 to apply voltage to the two ends of the conductive member 300, so as to ensure that the voltage is uniformly applied to the multiple pressure needle assemblies 200, thereby ensuring that the voltage is uniformly applied to the grid lines 23 of the sheet material 2, thereby improving the uniformity of the current of the sheet material 2. For example, as Figure 2 As shown, two wires 500 are connected to two ends of the conductive member 300 respectively.
[0073] In some embodiments, Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the pressure needle assembly 200 includes a connection body 210 and a conductive sheet 220, the connection body 210 is connected to the installation assembly 100, the conductive sheet 220 and the connection body 210 are arranged at an angle greater than 0° and less than 180°, the first end 2201 of the conductive sheet is connected to the connection body 210, and the second end 2202 of the conductive sheet contacts or separates from the sheet material 2 under the drive of the drive assembly 30. When the second end 2202 of the conductive sheet contacts the sheet material 2 under the drive of the drive assembly 30, the sheet material 2 applies a force to the second end 2202 of the conductive sheet, and a part of the force is transmitted to the connection body 210 through the second end 2202 of the conductive sheet to generate a tipping force on the connection body 210, and at the same time, the conductive connector 400 applies a force opposite to the tipping force to the connection body 210 to prevent the connection body 210 from tipping and shifting. Exemplarily, the connection body 210 is slidably connected to the installation body 110.
[0074] The first end 2201 of the conductive sheet is fixedly connected to the connection body 210.

[0075] For example, Figure 6 As shown, the connection body 210 has a notch 2140 to facilitate installation of the conductive sheet 220 .
[0076] The shape of the conductive sheet 220 may be L-shaped, Z-shaped, or other irregular shapes, which is not specifically limited in the present disclosure.
[0077] In some embodiments, the mounting assembly 100 has a plurality of guide holes 101, and the connecting body 210 includes a guide portion 2110, and the guide portion 2110 penetrates into the guide hole 101, so that the pressing needle assembly 200 can slide along the guide hole 101.

[0080] For example, Figure 8 As shown, the connection body 210 further includes a limiting portion 2120, which is located at one end of the connection body 210 away from the conductive sheet 220, and is used to limit the pressure needle assembly 200 to prevent the pressure needle assembly 200 from coming off the installation body 110. The limiting portion 2120 is fixedly connected to the guide portion 2110, and the limiting portion 2120 can be non-detachably connected to the guide portion 2110 by welding, bonding, etc., or the limiting portion 2120 can be detachably connected to the guide portion 2110 by bolts, nuts, screws, buckles, magnetic attraction, etc.
[0081] In some embodiments, Figure 7 and Fig. 9 As shown, the installation body 110 has a guide groove 102, and the extension direction of the guide groove 102 is the same as the extension direction of the guide hole 101.

The guide groove 102 guides the pressure needle assembly 200 for sliding.
[0082] The guide protrusion 240 is fixedly connected to the connection body 210. The guide protrusion 240 can be non-detachably connected to the connection body 210 by welding, bonding, etc., or the guide protrusion 240 can be detachably connected to the connection body 210 by bolts, nuts, screws, snaps, magnetism, etc.

[0085] In some embodiments, the conductive member 300 is disposed above the mounting assembly 100 and at least partially covers the guide slot 102 to limit the movement range of the guide protrusion 240 in the guide slot 102 .
[0086] For example, Figure 2 As shown, the conductive member 300 is disposed above the mounting body 110 , and the conductive member 300 is in the shape of a long rectangular strip.

[0091] In some embodiments, Figure 2 As shown, two conductive devices 10 are arranged on both sides of the sheet material 2, and the driving component 30 drives the two conductive devices 10 to move at the same time, so that the pressure needle components 200 of the two conductive devices 10 contact both sides of the gate line 23 at the same time to ensure that the voltage is more evenly applied to the gate line 23, so as to further improve the uniformity of the current of the sheet material 2.
