Description
Technical Field
The invention relates to the field of solar photovoltaic cells, in particular to a double-graphite-boat cache cooling device suitable for a TOPCon cell.
Background
The aim of improving the conversion efficiency of the solar cell is always pursued in the photovoltaic industry. The silicon-based solar cell efficiency limit was 29%, and the current highest cell efficiency was recorded to be 26.63%, which was created in 2017 by kaneka corporation of japan. The sources of solar cell efficiency loss are divided into optical loss, electrical loss and recombination loss. With the continuous improvement of the quality of silicon wafers, the surface recombination loss of the crystalline silicon battery becomes a key factor restricting the improvement of the battery efficiency, so the surface passivation technology is particularly important.
At present, the PERC cell with extremely high attention is passivated by introducing an aluminum oxide/silicon nitride dielectric layer on the back surface and adopting local metal contact, thereby effectively reducing the electronic recombination on the back surface and improving the cell conversion efficiency. But since the PERC cell limits the contact area of the back surface to the open pore region, a high recombination rate at the open pore still exists.
In order to further reduce the back recombination rate, realize the whole back passivation and remove the back film opening process, the passivation contact technology becomes an industrial research hotspot in recent years. The technique of TOPCon (Tunnel Oxide Passivated contact) developed by Fraunhofer ISE is one of the passivation contacts.
The TOPCon technique is to prepare an ultra-thin tunnel oxide layer and a highly doped polysilicon thin layer on the back of the cell, which together form a passivation contact structure, as shown in fig. 1. The structure provides good surface passivation for the back of the silicon chip, the ultrathin oxide layer can enable multi-electron tunneling to enter the polysilicon layer and simultaneously block minority hole recombination, and then electrons are transversely transmitted in the polysilicon layer and collected by metal, so that metal contact recombination current is greatly reduced, and open-circuit voltage and short-circuit current of a battery are improved.
Therefore, the TopCon structure does not need back opening and alignment, and does not need to additionally add local doping process, thereby greatly simplifying the cell production process. Compared with an N-PERT battery, the TOPCon technology only needs to add thin film deposition equipment, can be well compatible with the existing mass production process, and is convenient for upgrading a production line. Meanwhile, the doped polysilicon layer has good passivation characteristics and the back metal full-contact structure has a space for further improving the conversion efficiency, so that the mass production efficiency of the N-type cell exceeds 23%, and the doped polysilicon layer becomes the entry point of the next generation of industrialized N-type high-efficiency cell.

According to an embodiment of the present invention, referring to fig. 2 and fig. 3, it can be seen that the dual graphite boat buffer cooling device 1 suitable for TOPCon battery comprises a buffer cooling box 11, and a cooling mechanism 12 and at least two sets of graphite boat buffer mechanisms 13 arranged in the buffer cooling box 11, wherein the cooling mechanism 12 is installed on the top wall 112 of the buffer cooling box 11, the graphite boat buffer mechanisms 13 are installed on the side wall 111 of the buffer cooling box 11 and are located right below the cooling mechanism 12,
the graphite boat buffer mechanism 13 includes a left pilot assembly 131, a right pilot assembly 132 and a middle pilot assembly 133, which are disposed on the same horizontal plane, wherein the middle pilot assembly 133 is disposed between the left pilot assembly 131 and the right pilot assembly 132;
the middle pilot assembly 133 comprises a middle fixed cross beam 1331 fixedly connected to the side wall 111 and a bidirectional pilot piece 1332 mounted on the middle fixed cross beam 1331;
the bidirectional guiding piece 1332 includes a first middle supporting portion 1332a, a middle fixing portion 1332b and a second middle supporting portion 1332c, the middle fixing portion 1332b is fixedly mounted on the middle fixing cross beam 1331, the first middle supporting portion 1332a and the second middle supporting portion 1332c are respectively opposite to the left guiding component 131 and the right guiding component 132, and the first middle supporting portion 1332a and the second middle supporting portion 1332c are respectively connected with the middle fixing portion 1332b through a middle guiding skirt portion 1332 d. The bidirectional guide piece 1332 with the above structural design can sufficiently support the graphite boat 2 placed on the graphite boat buffer mechanism 13.
In a preferred embodiment, the graphite boat buffer mechanisms 13 are layered from top to bottom on the side wall 111 of the buffer cooling tank 11. In the embodiment shown in fig. 3 to 6, the graphite boat buffer mechanism 13 is located right below the cooling mechanism 12 and is layered from top to bottom to have 6 layers, the space arrangement is reasonable and the structure is compact by adopting the structural design, the heat dissipation function can be realized only by arranging a group of cooling mechanisms 12 right above the multilayer graphite boat buffer mechanism 13, which means that the occupied space of the graphite boat buffer mechanism 13 in the longitudinal direction is kept quite small, and a large half of the cooling mechanism 12 and the corresponding space occupation are also saved, so that the overall weight of the equipment is reduced on one hand, and the preparation cost of the equipment is also reduced on the other hand.
Referring again to fig. 7 and 8, it can be seen that the center pilot assembly 133 is disposed between the left pilot assembly 131 and the right pilot assembly 132 at intervals to form a graphite boat buffer station between the center pilot assembly 133 and the left pilot assembly 131 and between the center pilot assembly 133 and the right pilot assembly 132.
Reference will now be made to fig. 8, 17 and 18, which show in detail the guide positioning structure of the bidirectional guide piece 1332 for positioning the graphite boat 2 in the longitudinal direction (i.e., the X-axis direction in fig. 8), specifically, the middle guide skirt 1332d extending obliquely downward from the middle fixing portion 1332b in a direction close to the first middle support portion 1332a or the second middle support portion 1332 c. With this structural design, when the graphite boat 2 is placed in the graphite boat buffer station on the graphite boat buffer mechanism 13, the graphite boat 2 can be guided to a predetermined position in the longitudinal direction of the graphite boat 2 (i.e., the X-axis direction in fig. 8) under the guide cooperation of the gravity of the graphite boat 2 and the center guide skirt 1332 d.
Referring now to fig. 8, 9 and 11, the guiding and positioning structure of the bidirectional guiding piece 1332 for positioning the graphite boat 2 in the width direction (i.e., the Y-axis direction in fig. 8) is shown in detail, specifically, a first transverse guiding block 1334 is fixedly connected to each end of the first middle supporting portion 1332a and the second middle supporting portion 1332c, so that a first transverse guiding channel is formed between every two first transverse guiding blocks 1334 on the same side, and a first transverse guiding surface extending obliquely downward is formed on the inner side of the first transverse guiding block 1334, so that the width of the first transverse channel is gradually reduced in the direction from top to bottom. With this structural design, when the graphite boat 2 is placed in the graphite boat buffer station on the graphite boat buffer mechanism 13, the graphite boat 2 can be guided to a predetermined position in the width direction of the graphite boat 2 (i.e., the Y-axis direction in fig. 8) by the cooperation of the self-weight of the graphite boat 2 and the guide of the first lateral guide block 1334. To this end, by the bidirectional engagement of the center guide skirt 1332d and the first lateral guide block 1334, the graphite boat 2 can be guided and positioned to a predetermined position on the side opposite to the center guide assembly 133 when the graphite boat 2 is placed in the graphite boat buffer station on the graphite boat buffer mechanism 13.
As can be seen from fig. 7 and 8, in a specific implementation process, the left polarization assembly 131 and the right polarization assembly 132 are disposed to be mirror images of each other with respect to the center polarization assembly 133. By adopting the structural layout design, the design workload, the design time and the design and manufacturing cost can be reduced.
Referring now to fig. 19 to fig. 22, a detailed structure of the left polarization assembly 131 is shown, and since the left polarization assembly 131 and the right polarization assembly 132 are mirror images of each other with respect to the middle polarization assembly 133, only the detailed structure of the left polarization assembly 131 is described herein, and the detailed structure of the right polarization assembly 132 may refer to the corresponding structure of the left polarization assembly 131 in a mirror image manner, which will not be described herein again.
Specifically, the left pilot assembly 131 includes:
a left fixed beam 1311, which is fixedly connected to the side wall 111; and
a one-way pilot 1312 installed on the left fixed beam 1311 in a half-clad or full-clad manner;
wherein, a left supporting portion 1312a is integrally formed at the bottom of the one-way pilot member 1312, and the left supporting portion 1312a extends from the one-way pilot member 1312 in a direction approaching the middle pilot assembly 133. The one-way guide member 1312 is designed as described above, and can sufficiently support the graphite boat 2 placed on the graphite boat buffer mechanism 13. Referring to fig. 8, the right pilot assembly 132 is correspondingly formed with a one-way pilot piece 1322, and a right support portion 1322a is integrally formed at the bottom of the one-way pilot piece 1322.
Referring again to fig. 19 and 20, the guiding and positioning structure of the one-way guiding piece 1312 for positioning the graphite boat 2 in the length direction (i.e., the X-axis direction in fig. 8) is shown in detail, and specifically, the length of the left support portion 1312a is greater than that of the one-way pilot member 1312, so that both ends of the left supporting portion 1312a protrude from both ends of the one-way pilot 1312, so that guide notches are formed between the left support portion 1312a and the one-way pilot member 1312 at both ends of the one-way pilot member 1312, wherein, two ends of the one-way guiding element 1312 are rotatably connected with guide rollers 1313 positioned at the guide notches, the rotation axis of the guide roller 1313 is parallel to the longitudinal direction of the left support portion 1312a (i.e. the Y-axis direction in fig. 19 and 20), so that the roller surface of the guide roller 1313 at least partially enters directly above the left support portion 1312 a. With such a structural design, when the graphite boat 2 is placed on the graphite boat buffer mechanism 13, the graphite boat 2 can be guided to a preset position in the length direction of the graphite boat 2 (i.e., the X-axis direction in fig. 8) under the guiding cooperation of the gravity of the graphite boat 2 and the guide rollers 1313.
Reference will now be made to fig. 8, 9 and 11, which show in detail the guide positioning structure of the one-way pilot 1312 for positioning the graphite boat 2 in the width direction (i.e., the Y-axis direction in fig. 8), specifically,
a second transverse guide block 1314 is fixedly connected to the end of the left supporting portion 1312a, so that a second transverse guide channel is formed between every two second transverse guide blocks 1314, and a second transverse guide surface extending obliquely downwards is formed on the inner side of each second transverse guide block 1314, so that the width of each second transverse channel is gradually reduced in the direction from top to bottom. With this structural design, when the graphite boat 2 is placed in the graphite boat buffer station on the graphite boat buffer mechanism 13, the graphite boat 2 can be guided to a predetermined position in the width direction of the graphite boat 2 (i.e., the Y-axis direction in fig. 8) by the cooperation of the self-weight of the graphite boat 2 and the guide of the second lateral guide block 1314. By the bidirectional cooperation of the guide rollers 1313 and the second lateral guide blocks 1314, when the graphite boat 2 is placed on the graphite boat buffer station of the graphite boat buffer mechanism 13, the graphite boat 2 can be guided and positioned to a predetermined position at the side opposite to the left guide assembly 131 and the right guide assembly 132.

Specifically, when no graphite boat 2 is cached on the graphite boat caching station, the pressure value sensed by the piezoelectric pressure sensor is zero, and the control system judges that the graphite boat caching station is in an idle state currently according to the pressure signal fed back by the piezoelectric pressure sensor; when the graphite boat 2 is guided and positioned to a preset position, the pressure trigger terminal is matched with the piezoelectric pressure sensor on the corresponding side, so that the pressure value detected by the piezoelectric pressure sensor is located in a preset accurate positioning pressure value interval, and the control system judges that the graphite boat 2 is guided and positioned correctly according to a pressure signal fed back by the piezoelectric pressure sensor; when the graphite boat 2 is not guided and positioned to a preset position, the pressure trigger terminal is not matched with the piezoelectric pressure sensor on the corresponding side, so that the pressure value detected by the piezoelectric pressure sensor is out of a preset correct positioning pressure value interval, and the control system judges that the graphite boat 2 is not guided to the preset position according to the pressure signal fed back by the piezoelectric pressure sensor. The control system can even be linked with a manipulator for taking and placing the graphite boat 2, when the double-graphite-boat buffer cooling device 1 still has idle graphite boat buffer stations, the manipulator is controlled to place the graphite boat 2 on the corresponding graphite boat buffer station, and in the placing process, if the control system judges that the graphite boat 2 is guided and positioned to the preset position, the manipulator is informed that the current placing operation is finished; and if the control system judges that the graphite boat 2 is not guided and positioned to the preset position, the control system informs the manipulator to execute the current placing operation again until the graphite boat 2 is guided and positioned to the preset position.
