Abstract
The invention discloses a caterpillar assembly of a solar cell sintering furnace. The caterpillar assembly comprises a caterpillar, a silicon wafer, an aluminum back surface field and an oblique angular metal support frame. The aluminum back surface field is arranged on the back surface of the silicon wafer, the metal support frame is arranged on the caterpillar, and the edge of the back surface of the silicon wafer is erected by the metal support frame. The caterpillar assembly has the advantages that the edge dimension of the aluminum back surface field is smaller than the size of the silicon wafer, and the silicon wafer is erected by the metal support frame, so that the metal support frame can be prevented from being in direct contact with the aluminum back surface field or affecting infrared light when the infrared light irradiates on the aluminum back surface field, sintering of the aluminum back surface field is unaffected, and the integral efficiency of a cell can be improved.
Description
Technical field
The present invention relates to a kind of track assembly, particularly a kind of solar cell sintered furnace track assembly.
Background technology
Existing solar cell sintered furnace track assembly is to utilize the aluminium back surface field region at the strong point contact back side by silicon chip jack-up, make not contact track of silicon chip back side, metallic support point can conduct heat and block the aluminium back surface field of Infrared irradiation silicon chip back side like this, the aluminium back surface field high temperature sintering weak effect that makes contact zone, can cause the Efficiency Decreasing in this region.
Summary of the invention
Goal of the invention: the track assembly metallic support point that the object of the invention is to solve prior art is with aluminium back surface field thermal contact conductance and block Infrared irradiation aluminium back surface field, thereby causes the problem of the aluminium back surface field high temperature sintering weak effect of contact zone.
Summary of the invention: the invention provides following technical scheme: a kind of solar cell sintered furnace track assembly, comprise crawler belt, silicon chip and be located at the aluminium back surface field of silicon chip back side,, also having comprised the metal supporting frames of being located at the bevel on crawler belt, metal supporting frames is erected silicon chip back side edge.
As optimization, the limit, oblique angle that described metal supporting frames contacts with silicon chip edge and the angle of crawler belt are between 10-45 °.
As optimization, the width of the base that described metal supporting frames contacts with crawler belt is between 0.5-15cm.
As optimization, the vertical range of described aluminium back surface field and crawler belt is between 5-30mm.
Beneficial effect: the present invention compared with prior art: crawler belt of the present invention adopts metal supporting frames and the silicon chip back side EDGE CONTACT of bevel, silicon chip is erected, aluminium back surface field region is not contacted with metal supporting frames, avoid Metal Contact conduct heat and block the problem that infrared light affects aluminium back surface field sintering, improved the efficiency of solar battery sheet integral body.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing solar cell sintered furnace track assembly;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the cell piece EL design sketch after existing solar cell sintered furnace track assembly sintering;
Fig. 4 is the cell piece EL design sketch after sintering of the present invention.
The specific embodiment
Now by reference to the accompanying drawings 1-4 the present invention will be further described in detail.
Comparative example
Existing solar cell sintered furnace track assembly, comprises crawler belt 1, metallic support point 2, aluminium back surface field 3
With silicon chip 4, wherein metallic support point 2 is arranged on crawler belt 1, and erect silicon chip 4, directly contact with aluminium back surface field 3, in sintering process due to conductive force with block the irradiation of infrared light to aluminium back surface field 3, can affect the aluminium back surface field high temperature sintering effect of contact zone, thereby cause EL design sketch as shown in Figure 3, upper from figure, there is the black speckle of part in cell piece, high temperature sintering causes subregion to damage, and affects the generating effect of cell piece.
Example one
Solar cell sintered furnace track assembly, comprise crawler belt 1, aluminium back surface field 3 and silicon chip 4, also comprised the metal supporting frames 5 of being located at the bevel on crawler belt 1, metal supporting frames 5 is fixed on crawler belt 1 by base 6, the width of base 6 is 10cm, the angle that is limit, Bian， oblique angle, oblique angle and crawler belt 1 with silicon chip 4 contact areas is 25 °.When silicon chip 4 is transferred on crawler belt 1 in process, metal supporting frames 5 on crawler belt 1 is by contacting with the dorsal edge of silicon chip 4, silicon chip 4 is erected, make aluminium back surface field 3 regions of silicon chip 4 belows separated with crawler belt 1, aluminium back surface field 3 is 6mm with crawler belt 1 vertical range, because metal supporting frames 2 does not contact with aluminium back surface field 3 regions, avoid the impact of contact on aluminium back surface field 3 high temperature sinterings.
Example two
Solar cell sintered furnace track assembly, comprise crawler belt 1, silicon chip 4 and be located at the aluminium back surface field 3 at silicon chip 4 back sides, also comprised the metal supporting frames 5 of being located at the bevel on crawler belt 1, metal supporting frames 5 is fixed on crawler belt 1 by base 6, the width of base 6 is 10cm, the angle that is limit, Bian， oblique angle, oblique angle and crawler belt 1 with silicon chip 4 contact areas is 25 °.When silicon chip 4 is transferred on crawler belt 1 in process, metal supporting frames 5 on crawler belt 1 is by contacting with the dorsal edge of silicon chip 4, silicon chip 4 is erected, make aluminium back surface field 3 regions of silicon chip 4 belows separated with crawler belt 1, aluminium back surface field 3 is 12mm with crawler belt 1 vertical range, because metal supporting frames 5 does not contact with aluminium back surface field 3 regions, avoid the impact of contact on aluminium back surface field 3 high temperature sinterings.
Adopt solar cell sintered furnace track assembly of the present invention, because metal supporting frames 5 does not contact with aluminium back surface field 3, can not affect aluminium back surface field 3 sintering effects, as accompanying drawing 4 is observed by EL design sketch, with respect to existing solar cell sintered furnace track assembly, find and the point of Metal Contact district blackout, after improving, disappear.
