Background technology
Photovoltaic generation is one of generation technology of most sustainable development desired characteristics.Conventional fossil fuel approach exhaustion day by day, in all sustainable energies, solar energy is undoubtedly the most clean, the most general and most potential alternative energy source of one.At present, in all solar cells, silicon solar cell is one of solar cell obtaining business promotion on a large scale, this is because silicon materials have very abundant reserves in the earth's crust, the solar cell of other types compared by silicon solar cell simultaneously, has excellent electric property and mechanical performance.In the development of following photovoltaic technology, along with the further raising of silicon solar cell photoelectric properties, the further reduction of silicon materials price, silicon solar cell will occupy consequence at photovoltaic art.
At present, the production technology industrialization of silicon solar cell, its manufacturing process is generally: surface clean and texturing, diffusion, etching trimming, plated film, silk screen printing, sintering form ohmic contact, test.Wherein, be one of core process for making the diffusing procedure of PN junction.Existing diffusing procedure generally adopts high temperature dispersing furnace to spread; Namely silicon chip is placed in boiler tube, this needs to use quartz boat.Existing quartz boat comprises framework, is provided with support column in framework, and each support column is provided with a plurality of draw-in groove, and draw-in groove and adjacent card slot are in same plane and cooperatively interact, and forms silicon chip bearing groove; During use, silicon chip inserts in opened draw-in groove vertically.The bottom surface of framework is also provided with a pair fixed head.Along with the development of preparation technology, the design of quartz boat can be different.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of quartz boat.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of quartz boat, comprises framework, support column is provided with in framework, each support column is provided with a plurality of draw-in groove, and draw-in groove and adjacent card slot are in same plane and cooperatively interact, and forms silicon chip bearing groove;
Described framework comprises under(-)chassis, and is fixedly arranged on the lead on under(-)chassis; The bottom surface of described under(-)chassis is provided with a pair fixed head;
The long limit of described bottom frame is provided with wedge, makes the angle of its loading end and horizontal plane be 3 ~ 15 degree;
Angle between the loading end of described wedge and described lead is 90 degree.
Above, the long limit of described bottom frame is provided with wedge, make the angle of its loading end and horizontal plane be 3 ~ 15 degree, namely wedge be fixed at bottom frame long limit on, the loading end of wedge is used for placing carrying silicon chip group (silicon chip group is made up of multiple silicon chip).
Angle between the loading end of described wedge and described lead is 90 degree, and namely lead have also been made corresponding inclination, thus make to be positioned over silicon chip group on wedge loading end can overall run-off the straight, and there will not be the situation appeared because of inclination in silicon chip top.
Quartz boat of the present utility model achieves a kind of mode of carrying silicon chip completely newly, during use, by multiple silicon chip composition silicon chip group, then its entirety is put into quartz boat, carried by the wedge on the long limit of bottom frame, thus the diffusion operation that can to realize with silicon chip group be a group by a group object.Instead of as in prior art, piecemeal silicon chip is inserted in the draw-in groove of support column vertically.
Preferably, the loading end of described wedge and the angle of horizontal plane are 3 ~ 10 degree.
In technique scheme, described wedge and bottom frame are structure as a whole.
Preferably, described bottom frame is day font, and the long limit of bottom frame is provided with a pair symmetrically arranged wedge.Namely the incline direction at the two ends on the long limit of bottom frame is contrary, and make the vertical section on the long limit of bottom frame roughly in isosceles triangle, this structure has better stability.
In technique scheme, the long limit of frame roof is provided with quartz socket tube.
In technique scheme, the internal diameter of described quartz socket tube is greater than 10 mm, and the thickness of its tube wall is more than or equal to 3 mm
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, quartz boat of the present utility model achieves a kind of mode of carrying silicon chip completely newly, during use, by multiple silicon chip composition silicon chip group, then its entirety is put into quartz boat, carried by the wedge on the long limit of bottom frame, thus the diffusion operation that can to realize with silicon chip group be a group by a group object; Instead of as in prior art, piecemeal silicon chip is inserted in the draw-in groove of support column vertically; Thus substantially increase production capacity, save cost;
2, the silicon chip group in quartz boat of the present utility model can utilize silicon chip own wt, silicon chip a slice is made to press a slice, be bonded together more closely, thus may be used for that silicon chip is two-sided spreads different dopant simultaneously, fit together closely in the face of silicon chip dopant of the same race, continuous arrangement, the sheet number of One Diffusion Process is more;
3, quartz boat of the present utility model not only can be used for carrying silicon chip group, also as prior art, can be inserted vertically in the draw-in groove of support column by piecemeal silicon chip, spreads for routine;
4, structure of the present utility model is simple, and cost is lower, is suitable for applying.
