Abstract
The utility model relates to a quartz boat which is used in the solar sell diffusion technology and comprises an under frame, an upper frame and four slide glass rods, wherein the four slide glass rods are vertically arranged between the under frame and the upper frame and are enclosed into a rectangle, and horizontal slots which are used to insert cell slices are respectively arranged on a plurality of different horizontal planes of the four slide glass rods. The yield of processing the cell slices per hour of a diffusion furnace can be increased and the fragment rate can be reduced through adopting the quartz boat which is used in the solar sell diffusion technology to load the cell slices.
Description
Technical field
The utility model relates to the instrument that solar cell manufacture process is used, particularly a kind of solar cell diffusion technology quartz boat.
Background technology
Solar cell is an electric energy with solar energy converting as emerging clean reproducible energy directly because of having, and the life-span is long, it is simple to safeguard, can realize advantage such as unattended operation and get most of the attention.Solar power supply system has been obtained application more and more widely.
Diffusion technology needs to use a kind of device to be used to load silicon chip as the critical process in the production of crystalline silicon solar batteries process.This frock is made by quartz, is called quartz boat, to be fit to the high temperature of about 900 ℃ of diffusion technologys.
The employed diffusion furnace in prior art crystal-silicon solar cell field mostly is the horizontal diffusion furnace, the quartz boat that uses that matches with it is the horizontal quartz boat, on the horizontal cross bar of horizontal quartz boat, be provided with a plurality of vertical slots, silicon chip is vertically placed, insert two silicon chips in a groove during diffusion technology, so that form PN junction in the one side of silicon chip.Because the limited length of diffusion furnace tube, under this mode, there are the following problems:
1, every batch of technology sheet number is limited, and under existing equipment and the technology mode, every boiler tube hourly output is about 200.
2, because silicon chip is vertically to place, so, in technical process, be subjected to gravity effect, under hot environment, produce a large amount of stress if can not in time discharge, be easy to cause fragment.Under existing equipment and the technology mode, the diffusion technology fragment rate is about 0.2%.
The utility model content
The purpose of this utility model is to provide a kind of solar cell diffusion technology quartz boat of new structure.
The purpose of this utility model is achieved in that a kind of solar cell diffusion technology quartz boat, comprise underframe, upper frame and four slide glass bars, four slide glass bars are erect and are arranged between underframe and the upper frame and enclose rectangle, are respectively equipped with the level trough that is used to insert the battery sheet on a plurality of different levels of four slide glass bars.
Level trough on the described a plurality of different levels that are arranged on four slide glass bars is 40.
Adopt the utility model solar cell diffusion technology to load the battery sheet, can improve the per hour output of treatment of battery sheet of diffusion furnace, and reduce fragment rate with quartz boat.
Description of drawings
Fig. 1 is the perspective view of the utility model solar cell diffusion technology with quartz boat.
Embodiment
Referring to Fig. 1, the utility model solar cell diffusion technology quartz boat, comprise underframe 1, upper frame 2 and four slide glass bars 3, four slide glass bars 3 are erect and are arranged between underframe and the upper frame and enclose rectangle, are respectively equipped with the level trough that is used to insert the battery sheet (not shown come out) on 40 different levels of four slide glass bars.
The utility model is changed into quartz boat rectilinear by original horizontal, thereby has avoided the fragment that gravity factor causes in the technical process.Because quartz boat is vertically placed, the horizontal area that quartz boat accounts for is reduced to original below 1/2nd, make a diffusion furnace one-time process can place four quartz boats simultaneously, make every boiler tube hourly output can bring up to 320 battery sheets (40 level troughs of a quartz boat, every groove is put two battery sheets).
Table 1 is the horizontal quartz boat under the constant situation of other technologies, the mean value of the electrical performance data of 200 battery sheets that obtain; And by after the process modification, rectilinear quartz boat under the constant situation of other technologies, the mean value of the electrical performance data of 300 battery sheets that obtain.
