Description

Processing equipment for laser-induced sintering

Technical Field

The application belongs to the technical field of photovoltaic cells, and particularly relates to processing equipment for laser-induced sintering.

Background

The contact resistance between the front electrode and the back electrode of the crystalline silicon solar cell has a great influence on the filling factor and the conversion efficiency, and the lower the contact resistance is, the higher the filling factor and the conversion efficiency are. On the other hand, in order to pursue higher conversion efficiency, the sheet resistance of the emitter in the surface electrode of the crystalline silicon solar cell is made higher and higher, which makes it difficult to form lower contact resistance. The traditional airflow thermal cycle sintering furnace is difficult to form better ohmic contact when the slurry on the battery piece is sintered.

In order to reduce the contact resistance, the applicant uses a laser induced sintering technology to excite the battery carriers through laser and directionally flow and form a loop under the action of the reverse voltage of an external electric field, when the current of the loop flows through a metal-semiconductor interface, a more obvious thermal effect is generated because the contact resistance of the metal and the semiconductor is larger, and the heat can further promote the mutual diffusion of the metal and the semiconductor so as to obtain excellent contact characteristics after sintering. However, the applicant found that the photoelectric conversion efficiency of the battery needs to be further improved in the application process of the technology, and the economic benefit needs to be further improved.

The first driving mechanism 120 may be a linear driving mechanism, such as a linear motor, and the carrying device 100 may be an interactive module, or a rotary driving mechanism, such as a rotary motor, and the carrying device 100 may be a turntable module. The laser module 210 includes a laser for emitting a laser beam, and a laser scanning assembly for controlling a scanning direction of the laser beam, and the laser scanning assembly includes a galvanometer, a field lens, and the like, for example. The second drive mechanism 40 may be a lifting mechanism, such as a motor or a cylinder.

When the device is in operation, the first driving mechanism 120 moves to the processing station with the carrying table 110, the first electrode 10 is driven by the second driving mechanism 40 to contact the upper surface of the battery piece, the conductive connecting piece 20 is driven by the second driving mechanism 40 to contact the second electrode 130 contacting the lower surface of the battery piece, then the battery piece is electrified to apply voltage, meanwhile, the laser module 210 emits laser beams to scan the battery piece, after the processing is finished, the laser is closed, the first electrode 10 in the conductive module is driven by the second driving mechanism 40 to be no longer contacted with the battery piece, the conductive connecting piece 20 is driven by the second driving mechanism 40 to be no longer contacted with the second electrode 130, then the first driving mechanism 120 is driven by the carrying table 110 carrying the processed battery piece to be moved out from the processing station, and then the next battery piece is carried, and the process is repeated.

According to the laser-induced sintering processing equipment, as the bearing table 110 of the equipment comprises the second electrode 130 which is in contact with the lower surface of the battery piece, the bearing table 110 and the second electrode 130 can move to a processing station under the drive of the first driving mechanism 120, and the battery piece can be continuously conveyed; meanwhile, when the carrying table 110 moves to the processing station with the battery piece, the second driving mechanism 40 brings the first electrode 10 and the conductive connecting piece 20 into contact with the upper surface of the battery piece and the second electrode 130 respectively, so that the electric conduction and power failure can be quickly realized, and the mass production can be well realized. As another embodiment, the surface of the carrying platform 110 is at least partially the second electrode 130, where the whole carrying platform 110 may be made of a conductive material, the surface of the carrying platform 110 is the second electrode 130, and the battery chip is directly placed on the carrying platform 110 with conductivity; it is also possible to use a conductive material for only the surface of the carrier 110, and it is preferable that the outer surface (the periphery of the outer surface) of the carrier 110 has conductivity, and the lower surface of the battery piece is in contact with the surface of the carrier 110.

As another embodiment, the surface of the carrying platform 110 is provided with a conductive plate, which is used as the second electrode 130, and the conductive plate is in contact with the lower surface of the carried battery piece. Wherein the second electrode in the form of a plate may facilitate the contact of the second electrode 130 with the lower surface of the sheet-shaped battery cell. Specifically, the conductive plate may not be a complete whole panel, and it has a hollowed portion, and the carrying platform is made to partially pass through the hollowed portion to carry the battery piece, so that the lower surface of the battery piece may also be in contact with the surface of the carrying platform and the surface of the conductive plate at the same time.

Through the form that sets up the conducting plate at plummer 110 surface, only need the conducting plate select conductive material like this, when plummer 110 thickness is great, adopts and places the conducting plate and all adopts the scheme of conductive material with plummer 110 whole at plummer 110 surface to compare, this scheme can practice thrift the cost. In addition, considering that the carrying platform 110 may have other processing requirements, for example, it is made into a negative pressure adsorption carrying platform, so that the carrying platform 110 is convenient to select a material easy to process. Further, the material of the conductive plate is preferably copper because it has good conductivity and is relatively inexpensive.

As another example, the conductive plate carries the battery cells, that is, the battery cells are placed entirely on the conductive plate, and the carrying platform 110 may not be in contact with the battery cells at this time, which is the simplest implementation.

As another embodiment, the conductive plate is provided with a hollow structure, and through the hollow structure, fragments of the battery pieces caused by the slag can be avoided. Further, the bearing table 110 is also provided with a hollow structure, and the positions of the hollow structures correspond to each other in height, so that the battery piece fragments caused by the broken slag can be avoided through the hollow structure.

As another embodiment, the bearing table 110 is a negative pressure adsorption bearing table, that is, an adsorption cavity is provided inside the bearing table 110, a plurality of first adsorption channels are provided on the surface of the bearing table, the first adsorption channels are communicated with the adsorption cavity, and the adsorption cavity is communicated with the vacuum generating device.

or as another scheme, the conductive plate does not cover the first adsorption channel, specifically, the conductive plate has a hollowed-out portion, at least part of the first adsorption channel faces the hollowed-out portion, and the first adsorption channel is used for adsorbing and fixing the battery piece on the conductive plate so as to prevent the position of the battery piece from being shifted in the moving process of the bearing table 110.

As another example, the size of the conductive plate is larger than the size of the battery plate, and the second drive mechanism 40 contacts the conductive plate with the conductive connection member 20 in an area other than the battery plate. The projection of the first electrode 10 at the processing station on the horizontal plane faces to part of the main grid line of the battery piece, and the projection of the conductive connecting piece 20 on the horizontal plane faces to the area outside the battery piece on the conductive plate, so that the conductive connecting piece 20 is driven by the second driving mechanism 40 to contact the conductive plate underground more conveniently. Of course, the size of the conductive plate can be smaller than that of the battery plate, but in comparison, when the size of the conductive plate is larger than that of the battery plate, the conductive connector 20 can be more conveniently contacted with the conductive plate directly in a lifting manner, and the implementation is simpler.

As another embodiment, considering that the battery cells are placed on the conductive plate, that is, the height of the battery cells relative to the bearing table 110 is greater than the height of the conductive plate relative to the bearing table 110, and the first electrode 10 and the conductive connecting member 20 respectively contact the upper surface of the battery cells and the conductive plate, it is preferable that the height of the bottom of the first electrode 10 relative to the bearing table 110 is greater than the height of the bottom of the conductive connecting member 20 relative to the bearing table 110, so that the first electrode 10 does not crush the battery cells when the first electrode 10 and the conductive connecting member 20 move downward at the same time. Of course, in addition to making the lengths of the two electrodes different so as to have a height difference, the second driving mechanism 40 may also include two driving actuators, and the two driving actuators are adopted to respectively carry the first electrode 10 and the conductive connecting member 20 to perform lifting movement; alternatively, the conductive connector 20 may be designed to be articulated to avoid crushing the battery cells.

The Z-axis driving module can be a linear motor or an air cylinder. More specifically, as shown in fig. 2, the Z-axis driving module is connected to a support, and the first electrode 10 and the conductive connecting member 20 are both connected to the support, so that the first electrode 10 and the conductive connecting member 20 are both positioned above the carrier 110 while being supported on the support. As can also be seen from fig. 2, the conductive connection member 20 is located outside the first electrode 10, so that the projection of the first electrode 10 on the horizontal plane faces a part of the main grid line of the battery plate, and the projection of the conductive connection member 20 on the horizontal plane faces an area, other than the battery plate, on the conductive plate.

Further, the conductive connecting member 20 contacts the upper surface or the side of the conductive plate under the driving of the second driving mechanism 40. In addition to bringing the conductive connector 20 into contact with the second electrode 130 by the lifting drive as described above, the conductive connector 20 may be brought into contact with the upper surface or side of the conductive plate by other means, such as flipping.

As another embodiment, the first electrode 10 includes at least one strip-shaped electrode, and the electrode of the first electrode 10 includes any one of an elastic probe row (i.e. a plurality of elastic probes arranged in a line under the probe holder, the plurality of probes contacting the battery plate), an elastic conductive wire, and an elongated elastic electrode plate (the electrode plate contacts the whole surface of the battery plate). Of course, the first electrode 10 may also include a plurality of electrodes arranged side by side, and when a plurality of electrodes are provided, the plurality of electrodes are arranged in a direction perpendicular to the main gate line because the first electrode 10 is in contact with the main gate line in a stripe shape. It should be noted that, the stripe electrode herein means: since the first electrode 10 contacts the main grid line of the bit cell and the main grid line is stripe-shaped, the outer contour of the electrode projected on the horizontal plane is stripe-shaped (on a straight line) as a whole in order to make the first electrode 10 better contact with the main grid line.

As another example, the conductive connector 20 includes at least one conductive post, i.e., for electrical communication, it is only necessary that the conductive connector 20 have a contact for connection to the second electrode 130.
