Abstract
The utility model discloses a kind of crystal silicon solar energy battery phosphorus oxychloride storage device, comprise closed source bottle and be arranged on the air inlet pipe and escape pipe that are connected on the bottle of source and with source bottle, suspension block and bellows is provided with in the bottle of described source, described suspension block inner hollow is also provided with breather line, breather line one end is connected with air inlet pipe by bellows, and the other end is gas outlet.The beneficial effects of the utility model are by arranging suspension block and bellows, make the liquid level of phosphorus oxychloride liquid in solar cell emitter manufacture process along with the position generation respective change of carrying out air inlet of reaction, liquid is supplied not by the impact of liquid level change, thus reaches the steady consistency of liquid supply process.
Description
Technical field
The utility model relates to crystal silicon solar energy battery diffusion technology, is specifically related to a kind of phosphorus oxychloride storage device of silicon solar cell.
Background technology
Solar energy is clean as one, the reproducible energy, to its utilization always pay close attention to by people.How crystal silicon solar energy battery, as the main flow of current solar cell, reduces the cost of solar cell, raises the efficiency the emphasis becoming the research of domestic and international crystal silicon solar energy battery.
Emitter determines the performance of solar cell as the key components of solar cell, its doping content and the degree of depth, the direct efficiency affecting solar cell, in order to improve the efficiency of crystal silicon solar energy battery further, the preparation of high square resistance emitter, become the trend of industry at present, higher requirement be it is also proposed to the uniformity of emitter and short wave response simultaneously.Traditional diffusion technology, nitrogen is generally adopted to carry the diffusion of phosphorus oxychloride tubular type static state, because phosphorus oxychloride liquid level is along with the continuous step-down of processes expend, and air inlet pipe invariant position, the phosphorus oxychloride causing nitrogen to carry reduces gradually with the change of liquid level, thus cause technology stability to be deteriorated, the uniformity of emitter is caused to be deteriorated, ± the distribution of 3ohm/sq cannot be accomplished, what therefore the square resistance of silicon chip also cannot do is higher, bring certain difficulty to the preparation of late stage process, cause the transfer ratio of cell piece cannot mention a higher level.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of phosphorus oxychloride of crystal silicon solar energy battery constant supply storage device.
For solving the problems of the technologies described above, a kind of crystal silicon solar energy battery phosphorus oxychloride storage device of the present utility model, comprise closed source bottle and be arranged on the air inlet pipe and escape pipe that are connected on the bottle of source and with source bottle, suspension block and bellows is provided with in the bottle of described source, described suspension block inner hollow is also provided with breather line, breather line one end is connected with air inlet pipe by bellows, and the other end is gas outlet.
The operation principle of technique scheme is:
When the emitter of solar cell is prepared, along with the carrying out of reaction, liquid liquid level decreases, suspension block also fluctuates thereupon simultaneously, drive breather line to change along with the change of liquid liquid level thereupon, liquid is supplied not by the impact of liquid level change, thus reaches the steady consistency of liquid supply process.
Further, for making air inlet and giving vent to anger smooth and easy, air inlet pipe and escape pipe are arranged on bottle top, source.
Further, suspension block is cylinder.
Further, suspension block is cylinder or Elliptic Cylinder.
Further, increase the corrosion resistance of suspension block, suspension block is made up of quartz.
Further, also comprise quartz socket tube, one end of quartz socket tube is positioned at source bottle inner bottom part and is not connected with source bottle, and the other end extends to source bottle outside; Quartz socket tube can ensure that outside plant can be accurately detected the temperature in the inner phosphorus source of source bottle, and it is inner to make phosphorus source be sealed in source bottle, not with external communication.
The beneficial effects of the utility model are: by arranging suspension block and bellows, make the liquid level of phosphorus oxychloride liquid in solar cell emitter manufacture process along with the position generation respective change of carrying out air inlet of reaction, liquid is supplied not by the impact of liquid level change, thus reaches the steady consistency of liquid supply process.In addition, material therefor acid-alkali-corrosive-resisting avoids the pollution problem of phosphorus source, and suspension block is circular or elliptic design, avoids corner angle end and source bottle is clashed into the unsafe factor caused; The utility model can also effectively put forward diffusion technology stability, improves short wave response, effectively promotes the utilance of phosphorus oxychloride, avoids liquid level deficiency in the bottle of source and will change the problems such as phosphorus source.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of crystal silicon solar energy battery phosphorus oxychloride of the utility model storage device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 shows a kind of embodiment of a kind of crystal silicon solar energy battery of the utility model phosphorus oxychloride storage device, illustrated crystal silicon solar energy battery phosphorus oxychloride storage device comprises closed source bottle 2 and is arranged on the air inlet pipe 1 and escape pipe 6 that are connected on source bottle 2 and with source bottle, cylinder suspension block 4 and bellows 3 that quartz makes is provided with in source bottle 2, described suspension block 4 inner hollow is also provided with breather line, one end of breather line is connected with air inlet pipe 1 by bellows 3, the other end is gas outlet 5, air inlet pipe 1 and escape pipe 6 are arranged on source bottle 2 top, storage device is also provided with quartz socket tube 7, one end of quartz socket tube 7 is positioned at source bottle 2 inner bottom part and with bottom source bottle 2 is not connected, the other end extends to source bottle 2 outside.
The operation principle of above-described embodiment is:
Silicon chip enters diffusing procedure after making herbs into wool cleaning, use source bottle liquid level along with phosphorus source in diffusion process constantly reduces, breather line is suspended in phosphorus source, along with the consumption breather line exit position in phosphorus source decreases, ensure that the amount of the phosphorus oxychloride that nitrogen carries in diffusion process Center Vent tube road is constant all the time.Compared with the bottle of existing source, this phosphorus oxychloride storage device substantially increases the uniformity of emitter resistance.
As mentioned above, although represented with reference to specific preferred embodiment and described the utility model, it shall not be construed as the restriction to the utility model self.Under the spirit and scope prerequisite of the utility model claim interpretation, various change can be made in the form and details to it.
