Abstract
The utility model relates to the field of manufacturing crystalline silicon solar cells, in particular to a basket device for wet-method texturing of a solar cell. The device comprises a cross beam assembly and a support, wherein the cross beam assembly consists of a fixed cross beam arranged above the support and support cross beams arranged on the left and right side surfaces of the support and below the support; the four cross beams are parallel; uniformly distributed protrusions are arranged on the inner surfaces of the left and right support cross beams and on the upper surface of the lower support cross beam; and a clamp groove is formed between two adjacent protrusions. The basket print caused by insufficient reaction due to contact of the surface of a silicon wafer and the basket can be effectively reduced, the yield is improved, and the cost of the enterprise is reduced.
Description
Technical field
The utility model relates to crystal-silicon solar cell and makes the field, is that a kind of solar cell wet-method etching is used gaily decorated basket device.
Background technology
Photovoltaic industry competition now is fierce day by day, and except improving efficiency of conversion, reducing cost also is the road that must have of Business survival and development.The quality of making herbs into wool is to improve the first step critical processes of yield, in wet-method texturing manufacturing process, usually silicon chip is put into the gaily decorated basket; Immerse again and carry out making herbs into wool in the chemical liquid; But the gaily decorated basket is used in original silicon chip making herbs into wool, and silicon chip produces gaily decorated basket seal owing to can not fully reacting with chemical agent with gaily decorated basket contact both sides, causes the outward appearance of silicon chip and quality to descend to some extent; Product percent of pass reduces, and the generation probability that how to reduce gaily decorated basket seal is a problem that presses for solution.
Summary of the invention
The purpose of the utility model is exactly that a kind of solar cell wet-method etching that provides to the defective of above-mentioned existence is used the gaily decorated basket; This gaily decorated basket can effectively reduce in the making herbs into wool process and causes reacting insufficient " gaily decorated basket seal " that causes owing to silicon chip surface contacts with the gaily decorated basket; Improve the product yield, reduce enterprise cost.
A kind of etching solar cells of the utility model uses gaily decorated basket technical scheme to do, comprises transverse beam assembly and support, and said transverse beam assembly is made up of rack-mount side's the fixed cross beam and the supporting traverse of support left and right side and below, and four crossbeams are parallel to each other; The upper surface of the internal surface of left and right supporting traverse and following supporting traverse is provided with the convexity of evenly arranging, and forms draw-in groove between two adjacent protrusion.
The dismantled and assembled support top of being fixed in of described fixed cross beam.
The convexity that the upper surface of the internal surface of described left and right supporting traverse and following supporting traverse is provided with is the elliptical table shape, and there is concavo-convex decorative pattern the protruding side of elliptical table shape.
Said rack side wall is provided with perforate.
The material that the gaily decorated basket of the utility model selects for use tetrafluoroethylene etc. to be insoluble to strong acid and strong base is processed.
The beneficial effect of the utility model is: this etching solar cells comprises transverse beam assembly and support with the gaily decorated basket, and said transverse beam assembly is made up of rack-mount side's the fixed cross beam and the supporting traverse of support left and right side and below, and four crossbeams are parallel to each other; The upper surface of the internal surface of left and right supporting traverse and following supporting traverse is provided with the convexity of evenly arranging, and forms draw-in groove between two adjacent protrusion.Adopt this beam structure to improve the existing gaily decorated basket, and only use a bottom end rail, also reduced the contact area of the gaily decorated basket and silicon chip owing to both sides sidewall and the excessive making herbs into wool non-uniform phenomenon that causes of silicon chip contact surface.
The dismantled and assembled support top of being fixed in of fixed cross beam makes things convenient for picking and placeing of silicon chip.
The convexity that the upper surface of the supporting traverse of the internal surface of described left and right supporting traverse and support below is provided with is the elliptical table shape, and there is concavo-convex decorative pattern the protruding side of elliptical table shape, has further reduced contacting of the gaily decorated basket and silicon chip.
This gaily decorated basket can effectively reduce in the making herbs into wool process and causes reacting insufficient " gaily decorated basket seal " that causes owing to silicon chip surface contacts with the gaily decorated basket, improves the product yield, reduces enterprise cost.
Description of drawings:
Shown in Figure 1 is the utility model structural representation;
Fig. 2 is the convexity that the internal surface of left and right supporting traverse on the gaily decorated basket of the utility model and the upper surface that descends supporting traverse are provided with.
Among the figure, 1. support; 2. perforate; 3. fixed cross beam; 4. left and right supporting traverse; 5. descend supporting traverse, 6. convexity; 7. decorative pattern.
Embodiment:
In order to understand the utility model better, below in conjunction with the technical scheme of accompanying drawing detailed description the utility model, but the utility model is not limited thereto.
A kind of etching solar cells of the utility model uses gaily decorated basket technical scheme to do; Comprise transverse beam assembly and support 1; Said transverse beam assembly is made up of the fixed cross beam that is installed in support 1 top 3 and the supporting traverse of support 1 left and right side and support below, and four crossbeams are parallel to each other; The upper surface of the internal surface of left and right supporting traverse 4 and following supporting traverse 5 is provided with 6 of 6, two adjacent protrusion of convexity of all arranging and forms draw-in groove.
Described fixed cross beam 3 dismantled and assembled support 1 tops of being fixed in.
The convexity 5 that the upper surface of the internal surface of described left and right supporting traverse 4 and following supporting traverse 5 is provided with is the elliptical table shape, and there is concavo-convex decorative pattern 6 the protruding side of elliptical table shape.
Said support 1 sidewall is provided with perforate 2.
The material that the gaily decorated basket of the utility model selects for use tetrafluoroethylene etc. to be insoluble to strong acid and strong base is processed.
During use, open fixed cross beam 3, silicon chip is vertically neatly put in the middle of the draw-in groove of left and right supporting traverse 4 and supporting traverse 5 rats 5 formation down; Fixedly mounted fixed cross beam 3 then, the gaily decorated basket has been put into chemical agent, silicon chip has been corroded making herbs into wool; After silicon chip making herbs into wool and cleaning, the drying, open gaily decorated basket fixed cross beam 3, take out the good silicon chip of making herbs into wool.
