Description

Technical Field

[0001] The present disclosure relates to the field of photovoltaic or semiconductor technology, and in particular to a sheet carrier and a sheet transport system. Background Art

[0002] At present, the industry uses deposition equipment to coat the cross-section of the laser-cut silicon wafers, and then welds the silicon wafers in series to ensure the conversion efficiency of the solar cells. In order to reduce the phenomenon of silicon wafer wrapping, the silicon wafers are usually stacked and placed in a coating carrier, and the coating carrier is used to cover the non-cross-section of the silicon wafer.

[0003] In the related art, the air intake method of the coating carrier is to set a long strip of air inlet and outlet on the coating carrier, and the passivation gas enters and exits the coating carrier through the air inlet and outlet. When multiple silicon wafers are stacked and placed on the coating carrier, the air inlet and outlet are located on the side of the silicon wafer, and the air flow direction is parallel to the stacking direction of the cross-section of the multiple silicon wafers. Under the premise of ensuring a good coating effect, in order to minimize the plating around the silicon wafer, the size of the air inlet and outlet is usually set to be relatively small, which leads to the weakening of the air flow conduction inside the coating carrier. When the gas flows from one side of the coating carrier to the other side of the coating carrier, the uniformity of the air flow is poor, resulting in poor consistency of the coating effect of the cross-section of the multiple silicon wafers.

[0027] 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.

[0028] In the photovoltaic field, the voltage of solar crystalline silicon cells is independent of area, while power is proportional to area. The standard specification cell is cut into two identical half-cells perpendicular to the main grid line of the cell by laser cutting, and then welded in series. Since the current inside the cell is reduced by half, and the power loss is proportional to the square of the current, the power loss of the entire component is reduced to one-fourth of the original whole cell component, and the output power of the battery is about 5-10W higher than that of the same type of whole cell component. At the same time, in order to effectively reduce the power loss caused by shading due to its special series-parallel structure, the hot spot temperature of the half-cell battery component is about 25°C lower than that of the same type of whole cell component. Therefore, the half-cell battery component has stronger competitiveness in terms of mainstream power, stability, cost-effectiveness, etc. in large-scale mass production, and is expected to become the main choice of component products in the future.

[0029] In order to reduce the edge recombination of the cell during the laser cutting process, the atomic layer deposition (ALD) method is usually used, that is, by alternately passing the gas phase precursor into the reaction chamber and causing the gas-solid phase chemical adsorption reaction on the surface of the deposition substrate to form a thin film, a certain thickness of aluminum oxide film is deposited on the surface of the section, thereby passivating the section by using the excellent chemical passivation of aluminum oxide and the field passivation induced by the fixed negative charge. The ALD process is characterized by repeated cycles of passing the source gas, then passing the nitrogen gas to purge, then passing the source gas to purge, and then repeating the cycle of film coating. When the process environment is narrow and the source gas is not purged cleanly, ALD is easily converted into Chemical Vapor Deposition (CVD) which reacts more rapidly and is more difficult to control to continue the film coating.

[0030] Since the aluminum oxide film only needs to be deposited on the cross-section, the silicon wafer is placed in a coating carrier in a stacked manner. The coating carrier is used to cover the non-cross-section of the silicon wafer, leaving only the cross-section of the silicon wafer exposed, so as to reduce the phenomenon of silicon wafer wrap-around plating.

[0031] In the related art, the air intake method of the coating carrier is to set a long strip of air inlet and outlet on the coating carrier, and the passivation gas enters and exits the coating carrier through the air inlet and outlet. When multiple silicon wafers are stacked and placed on the coating carrier, the air inlet and outlet are located on the side of the silicon wafer, and the air flow direction is parallel to the stacking direction of the cross-section of the multiple silicon wafers. Under the premise of ensuring a good coating effect, in order to minimize the plating around the silicon wafer, the size of the air inlet and outlet is usually set to be relatively small, which leads to the weakening of the air flow conduction inside the coating carrier. When the gas flows from one side of the coating carrier to the other side of the coating carrier, the uniformity of the air flow is poor, resulting in the cross-sectional thickness of the film layer of the cross-section of the silicon wafer close to the air inlet end is always greater than the cross-sectional thickness of the film layer of the cross-section of the silicon wafer close to the air outlet end, resulting in uneven coating thickness of the cross-section of the multiple silicon wafers, thereby resulting in poor consistency of the coating effect of the cross-section of the multiple silicon wafers.

[0032] In addition, when the size of the inlet and outlet is small, the air flow inside the coating carrier becomes weak, and the excess gas is difficult to flow out of the coating carrier, resulting in residual gas in the coating carrier, which aggravates the wrapping phenomenon of the silicon wafer and also affects the coating effect of the next batch of silicon wafers. The consistency of the coating effect includes: the consistency of the thickness of the coating layer and the uniformity of the film color of the film layer.

[0033] In addition, in the related art, a gasket is usually used to adjust the size of the air inlet and outlet to achieve the optimal size, so as to adjust the air intake to the optimal air intake as much as possible, thereby achieving the premise of ensuring a good coating effect on the cross section of the silicon wafer and reducing the plating phenomenon as much as possible. Usually, the size of the gasket is larger than the size of the silicon wafer, which causes the gap between the non-cross section of the silicon wafer and the coating carrier to become larger, thereby causing more gas to enter the gap, thereby aggravating the plating phenomenon on the non-cross section of the silicon wafer.

[0034] In view of the above problems, the embodiments of the present disclosure provide a sheet carrier, the air inlet and outlet surface of the sheet carrier has a plurality of air holes, when multiple sheets of sheet materials are stacked and placed on the sheet carrier, the cross-sections of the sheet materials face the air inlet and outlet surfaces, and the passivation gas can enter the sheet carrier through the plurality of air holes and flow to the cross-sections of the multiple sheets of sheet materials respectively, so as to perform a passivation process on the cross-sections of the multiple sheets of sheet materials. The above air intake method uses a plurality of air holes to intake air, which improves the uniformity of the airflow in the sheet carrier, thereby improving the consistency of the coating effect of the cross-sections of the multiple sheets of sheet materials.

[0035] In addition, multiple air holes increase the effective area of ​​air inlet and outlet, and increase the total air inlet and outlet volume, making it easier for more passivation gas to enter the sheet carrier and for excess passivation gas to flow out of the sheet carrier, thereby improving the coating efficiency. At the same time, it also avoids excessive passivation gas remaining in the coating carrier, which affects the coating effect and aggravates the winding plating phenomenon, and can also avoid the residual passivation gas from affecting the coating effect of the next batch of sheet materials.

[0036] In addition, the sheet carrier eliminates the gasket, which can reduce the gap between the non-section of the sheet material and the sheet carrier, thereby further reducing the wrap-around plating phenomenon.

[0037] In addition, the sheet carrier can adjust the air intake by adjusting the size of the air holes. The adjustment method is simple and low in cost, which is more conducive to the standardized production of the sheet carrier.

[0038] The specific structure of the sheet carrier is described below in conjunction with an embodiment.

[0039] Figure 1 Shown is a schematic structural diagram of a sheet material handling system provided in one embodiment of the present disclosure. Figure 2 Shown is a schematic structural diagram of a sheet carrier provided in one embodiment of the present disclosure. Figure 3 Shown is a top view of a sheet carrier provided in accordance with an embodiment of the present disclosure. Figure 4 Shown Figure 3 The sheet carrier is shown in a cross-sectional view along the AA direction. Figure 5 FIG. 1 is a schematic diagram of the structure of a boat and a sheet carrier provided by an embodiment of the present disclosure. Figures 1 to 5As shown, the sheet carrier 10 includes a cavity 100, and the cavity 100 has a first accommodating cavity 101, and the first accommodating cavity 101 is configured to accommodate multiple sheets of sheet materials 2 placed in a stacked manner. The cavity 100 also has an opening 102, and the opening 102 is connected to the first accommodating cavity 101. The sheet material 2 enters and exits the first accommodating cavity 101 through the opening 102 along a first direction X1, and the first direction X1 intersects with the plane where the opening 102 is located. One surface of the cavity 100 is an air inlet and outlet surface 103, and the air inlet and outlet surface 103 has a plurality of air holes 1030, and the air holes 1030 connect the first accommodating cavity 101 and the outside of the cavity 100, and the air holes 1030 are used for passivation gas to enter and exit the first accommodating cavity 101. When multiple sheets of sheet materials 2 are located in the first accommodating cavity 101, the cross section 21 of the sheet materials faces the air inlet and outlet surface 103, so that the passivation gas performs a passivation process on the cross section 21 of the multiple sheets of sheet materials.

[0040] Exemplarily, the sheet material handling device 20 may include a mechanical arm or other components, which are not specifically limited in the present disclosure. The sheet material handling device 20 is used to automatically pick and place multiple sheets of sheet materials 2, with a fast picking and placing speed and a short picking and placing time, which can shorten the processing time of the sheet material 2 and improve the processing efficiency of the sheet material 2.

[0041] Illustratively, the sheet material 2 may be a silicon sheet, a wafer, a glass substrate, or the like.

[0042] The cross-sectional shape of the cavity 100 may be a rectangle, a parallelogram, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0043] The cross-sectional shape of the opening 102 may be a rectangle, a trapezoid, or other polygonal or irregular shapes, which is not specifically limited in the present disclosure.

[0044] For example, the cross-sectional shape of the air hole 1030 may be circular, rectangular, or other polygonal or irregular shapes. The air holes 1030 may be arranged regularly or irregularly, which is not specifically limited in the present disclosure.

[0045] The air intake method of the sheet carrier 10 adopts a plurality of air holes 1030 to intake air, thereby improving the uniformity of the airflow in the sheet carrier 10 and further improving the consistency of the coating effect of the cross sections 21 of the multiple sheet materials.

[0046] In addition, one surface of the cavity 100 has a plurality of pores 1030, which effectively reduces the area of ​​one surface of the cavity 100, is beneficial to the heat dissipation in the first accommodating cavity 101, thereby shortening the heat dissipation time of the cavity 100, and further shortening the processing time of the sheet material 2, and further improving the processing efficiency of the sheet material 2.

[0047] In some embodiments, the cavity 100 includes: a bottom plate 110, a top plate 120, a first side plate 130, a second side plate 140, and a third side plate 150. The top plate 120 is arranged opposite to the bottom plate 110, and the top plate 120 forms an air inlet and outlet surface 103. When multiple sheets of sheet materials 2 are located in the first accommodating cavity 101, the multiple sheets of sheet materials 2 are stacked along the first direction X1. The first side plate 130 connects the bottom plate 110 and the top plate 120, and the second side plate 140 is arranged opposite to the first side plate 130, and connects the bottom plate 110 and the top plate 120. The third side plate 150 is arranged opposite to the opening 102, and the third side plate 150 connects the first side plate 130 and the second side plate 140, and connects the top plate 120 and the bottom plate 110. The structure of the cavity 100 is simple.

[0048] In some embodiments, the cross section 21 of the sheet material extends along the second direction X2, the second direction X2 is the direction in which the first side plate 130 is perpendicular to the second side plate 140, and the plurality of air holes 1030 are arranged in an array along the first direction X1 and the second direction X2. The arrangement of the plurality of air holes 1030 is neat and beautiful, which can improve the appearance of the cavity 100, and the neat arrangement is more convenient for processing the air holes 1030.

[0049] In some embodiments, the air hole 1030 includes a first hole 1031 and a second hole 1032, wherein the first hole 1031 connects the outside of the cavity 100 with the second hole 1032, and the second hole 1032 connects the first hole 1031 with the first accommodating cavity 101. The first hole 1031 and the second hole 1032 extend in the same direction, and in a direction perpendicular to the extending direction of the first hole 1031, the size of the first hole 1031 is larger than the size of the second hole 1032.

[0050] The passivation gas flows into the first hole 1031 from the outside of the cavity 100, and flows into the first accommodating cavity 101 after flowing through the second hole 1032. Since the size of the first hole 1031 is larger than the size of the second hole 1032 in the direction perpendicular to the extension direction of the first hole 1031, the second hole 1032 can buffer the passivation gas to reduce the flow rate of the passivation gas when it flows into the first accommodating cavity 101, thereby reducing the impact force of the passivation gas on the sheet material 2, so as to avoid affecting the coating effect of the cross section 21 of the sheet material due to excessive impact force of the passivation gas, and also to avoid more passivation gas from entering the gap between adjacent sheet materials 2, so as to reduce the circumferential plating phenomenon of the sheet material 2.

[0051] After the passivation is completed, the excess passivation gas flows from the first accommodating cavity 101 into the second hole 1032, flows through the first hole 1031 and then flows out of the cavity 100. Since the size of the second hole 1032 is smaller than the size of the first hole 1031 in the direction perpendicular to the extension direction of the first hole 1031, the one-way outflow of the excess passivation gas can be guaranteed, and the amount of residual passivation gas in the sheet carrier 10 can be further reduced to ensure a good coating effect on the cross section 21 of the sheet material and reduce the phenomenon of circumferential plating. It can also avoid the residual passivation gas from affecting the coating effect of the next batch of sheet materials 2 as much as possible.

[0052] Exemplarily, the extension directions of the first hole 1031 and the second hole 1032 may intersect the vertical direction and the horizontal direction, and the first hole 1031 and the second hole 1032 may also both extend along the vertical direction.

[0053] Exemplarily, when the cross-sections of the first hole 1031 and the second hole 1032 are both regular shapes, the centers of the first hole 1031 and the second hole 1032 coincide with each other.

[0054] In some embodiments, the first hole 1031 and the second hole 1032 both extend in the vertical direction to reduce the flow path of the passivation gas in the top plate 110, so that the passivation gas can flow into or out of the first accommodating cavity 101 faster, thereby further shortening the coating time of the sheet material 2 and further improving the coating efficiency.

[0055] In some embodiments, the cross-sectional shape of the first hole 1031 includes a circle, and the diameter of the first hole 1031 is less than 0.35 mm and greater than 0.15 mm. The cross-sectional shape of the second hole 1032 includes a circle, and the diameter of the second hole 1032 is less than 0.2 mm and greater than 0.1 mm. The circular hole is more convenient for machining. In addition, by reasonably setting the sizes of the first hole 1031 and the second hole 1032, the air intake of the passivation gas can be reasonably controlled. While ensuring the optimal air intake, the buffering effect of the second hole 1032 on the passivation gas is ensured to be optimal, so that the coating effect of the sheet material 2 is optimal and the wrap-around phenomenon is minimized.

[0056] In some embodiments, when the sheet material 2 is located in the first accommodating cavity 101, the difference between the vertical distance between the first side plate 130 and the second side plate 140 and the size of the sheet material 2 in the second direction X2 is less than 4.2 mm and greater than 1.3 mm. By reasonably setting the gap size between the non-section 22 of the sheet material and the first side plate 130 and the second side plate 140, the amount of passivation gas entering the gap is further reduced, thereby further reducing the plating phenomenon around the non-section 22 of the sheet material.

[0057] In some embodiments, the sheet carrier 10 is applied to a sheet transport device 20, and the sheet transport device 20 is configured to place the sheet material 2 on the sheet carrier 10 or take the sheet material 2 from the sheet carrier 10. The cavity 100 is an axisymmetric structure, and the first side plate 130 includes a first baffle 1310 and a second baffle 1320, the first baffle 1310 is connected to the top plate 120, and the second baffle 1320 is connected to the bottom plate 110, and a first notch 104 is formed between the first baffle 1310 and the second baffle 1320, and the first notch 104 is connected to the first accommodating cavity 101 and the opening 102 respectively. The third side plate 150 has a third notch 1501 at an edge close to the first side plate 130, and the third notch 1501 close to the first side plate 130 is connected to the first notch 104. When the sheet transporting device 20 places the sheet material 2 on the sheet carrier 10 or takes the sheet material 2 away from the sheet carrier 10, the sheet transporting device 20 penetrates the first notch 104 and the third notch 1501, so that the sheet transporting device 20 can automatically transport the sheet material 2.
