Abstract
The utility model relates to a source bottle for diffusion of a solar cell. The source bottle comprises an outer bottle melted from refractory glass, wherein an air inlet and an air outlet penetrating outside and inside of the outer bottle are arranged at the top part of the outer bottle; a glass tube is arranged at the tail end of the air inlet inside the outer bottle; an interlayer is arranged inside the outer bottle; the glass tube is serially communicated with the bottom part of the interlayer; at least three interlayers are provided; the upper ends of the air inlet and the air outlet are of groove shapes; air holes are arranged on the interlayers, and the diameter of each air hole is 8mm. The source bottle has the advantages that the source bottle for diffusion of the solar cell is easier to achieve, and has a practical significance; meanwhile, the utilization rate of phosphorus oxychloride inside the source bottle is improved; and the optimized source bottle does not increase additional burden or work, and the process stability is well controlled.
Description
Technical field
The utility model relates to a provenance bottle, relates in particular to a kind of solar cell diffusion and uses the source bottle.
Background technology
Conventional diffusion furnace is when adopting POCl3 (POCl3) diffusion system PN junction, and the continuous consumption of measuring owing to source in the production process reduces source amount liquid level, and the ability of gas-entrained POCl3 reduces.Conventional source bottle structure: incipient liquid level is 100mm, and the liquid level during end is 20mm, and liquid level drop (ratio)=100/20=5 is 8-12 Ω/ to the influence of spreading square resistance; For this situation, generally will spread square resistance and be controlled in the processing procedure through means such as frequent process modifications or adjustment; Therefore, this is for the modification or the preservation of stable, the technical recipe of technology and call and make troubles, and is easy to generate management and control is chaotic, causes the error calls of the unfavorable or technology of technology supervision, for production brings very big loss.
Summary of the invention
The utility model technical problem to be solved provide a kind of can avoid technology repeat revise or adjustment, make the more reliable and more stable solar cell diffusion of procedure for producing use the source bottle.
In order to solve the problems of the technologies described above; The utility model is realized through following technical scheme: the source bottle is used in a kind of solar cell diffusion; Comprise the outer blank that is formed by the pyroceram fusion, the outer blank top is provided with and connects its inside and outside inlet mouth and air outlet, and the said inlet mouth end that is positioned at outer blank is provided with grass tube; Be provided with interlayer in the said outer blank, grass tube is ganged up the interlayer bottom.
For raising source amount utilization ratio, further, said interlayer has three at least.
In order to improve the stopping property of total system source bottle, further, said inlet mouth and upper end, air outlet are groove shape.
In order to prevent that inlet mouth institute air inlet body from producing bubble, more further, said interlayer is provided with pore.
In order better to prevent to produce bubble, further, said hole diameter is 8mm.
Compared with prior art; The usefulness of the utility model is: this solar cell diffusion is prone to realize with source bottle optimization; Has practice significance; Improve the utilization ratio of POCl3 in the bottle of source simultaneously, the source bottle after the optimization can not increase added burden or work, and technology stability is had control preferably.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is that the diffusion of the utility model solar cell is with source bottle internal structure synoptic diagram;
Fig. 2 is the partial enlarged drawing of A among Fig. 1.
Among the figure: 1, outer blank; 2, inlet mouth; 3, air outlet; 4, grass tube; 5, interlayer; 6, pore.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
The source bottle is used in a kind of solar cell diffusion shown in Figure 1, comprises the outer blank 1 that is formed by the pyroceram fusion, has guaranteed the long-term repeated use of source bottle and not yielding; Said outer blank 1 top is provided with and connects its inside and outside inlet mouth 2 and air outlet 3, adopts groove design in the upper end of inlet mouth 2 and air outlet 3, and this design can improve the stopping property of total system source bottle, makes the source bottle safer, also helps process stabilizing; Said inlet mouth 2 ends that are positioned at outer blank 1 are provided with grass tube 4, are provided with three layers of interlayer 5 in the outer blank 1 at least, and said grass tube 4 is ganged up interlayer 5 bottoms; As shown in Figure 2, produce aeration in order to prevent the gas that inlet mouth 2 gets into, said interlayer 5 is provided with the pore 6 that diameter is 8mm.
During work; Inlet mouth 2 is as carrying gas port (like more stable gases of character such as nitrogen/argon gas); Go deep into the bottom of POCl3 liquid in the bottle of source through grass tube 4, gas-entrained part POCl3 molecule is brought the phosphorus source in the high quartz pipe into via air outlet 3 and to be spread; Owing in the bottle of source, be provided with interlayer 5, the interlayer 5 that therefore adds has simultaneously taken a part of volume, makes bottle interior POCl3 total surplus amount in source reduce, and promptly amount utilization ratio in source improves.
The incipient liquid level of source bottle after the optimization is 100mm; Liquid level during end is 20mm; The distance ≈ 42+70*2 ≈ 182mm that intermediate interlayer increases, liquid level drop (ratio) ≈ (100+182)/(20+182) ≈ 1.4 is 1-3 Ω/ to the influence of spreading square resistance.Therefore; This solar cell diffusion is prone to realize with source bottle optimization; Have practice significance, improve the utilization ratio of POCl3 in the bottle of source simultaneously, the source bottle after the optimization can not increase added burden or work; The source amount is reduced between 1.3～1.5 by 5:1 drop before, technology stability is had control preferably.
It is emphasized that: above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
