Abstract
The utility model relates to a phosphorus oxychloride diffusion source bottle for solar cells, which comprises a source bottle body (1), the top of the source bottle body (1) is provided with a liquid medicine filling inlet (2), an air inlet pipe (3) and an air outlet pipe (4) are inserted in the top of the source bottle body (1), the lower end of the air inlet pipe (3) is inserted to the bottom of the source bottle body (1), and the lower end of the air outlet pipe (4) is inserted to the middle of the source bottle body (1). The phosphorus oxychloride diffusion source bottle is characterized in that: the source bottle body (1), the air inlet pipe (3) and the air outlet pipe (4) are all made of ETPE (energetic thermoplastic polyurethane elastomer) or FEP (fluorinated ethylene propylene) materials, the bottom of the air inlet pipe (3) is upwards provided with an opening section (5), and the opening section (5) is provided with a plurality of small round holes.
Description
Technical field
The utility model relates to a kind of diffuse source bottle, relates in particular to a kind of solar cells with POCl3 diffuse source bottle, belongs to field of photoelectric technology.
Background technique
The crystal silicon cell technology successful Application with commercially produce, greatly promoted the process of human enjoyment clean energy resource.The PN junction of crystal silicon cell is its core work, when light is radiated on this PN junction, so-called photovoltaic effect can take place, and produces photoproduction electromotive force and photogenerated current and supplies with and load.The design of emmitting electrode is significant for the efficient that improves crystal silicon cell, and formation selectivity emissivity electrodes such as laser is auxiliary such as adopting, phosphorus ink print are a kind of effective designs.
Ripe tubular diffusion furnace, the diffusion scheme that provides is a gas-entrained source gas, chemical reaction at high temperature takes place in source gas, forms the core PN junction of crystal silicon cell then.As on P type silicon chip, carrying out the phosphorus diffusion; It is general that what adopt is that nitrogen carries POCl3 and brings the tubular type boiler tube into; At high temperature POCl3 and oxygen generation chemical reaction form phosphorus atoms; This phosphorus atoms has at high temperature successively experienced alternative diffusion, interstitial diffusion etc. and has formed the N type layer with certain Gradient distribution at silicon chip surface, has formed PN junction then.Liquid POCl3 generally is positioned in the source bottle of quartzy material, and its suction tude is the hollow tube of quartzy material.Slight crack takes place and bursts in the source bottle of this material easily when can is operated with carrying, the quartzy suction tude of hollow can not make full use of POCl3.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provide a kind of can and when operation carrying to be not easy to take place slight crack and burst, and the solar cells that can improve the POCl3 utilization ratio is with POCl3 diffuse source bottle.
The purpose of the utility model is achieved in that
A kind of solar cells is with POCl3 diffuse source bottle; It comprises the source bottle body; Bottle body top, said source is provided with the liquid medicine filling mouth, and bottle body top, said source also is inserted with gas inlet pipe and gas steam outlet pipe, and the lower end of said gas inlet pipe is inserted to bottle body bottom, source; The lower end of said gas steam outlet pipe plugs the bottle body middle part to the source; It is characterized in that said source bottle body, gas inlet pipe and gas steam outlet pipe all adopt ETPE or FEP material to process, the bottom of said gas inlet pipe upwards is provided with the perforate section, and said perforate section is provided with a plurality of circular apertures;
The length of said perforate section is 0.5 ~ 3 centimetre.
Compared with prior art, the beneficial effect of the utility model is:
The utility model solar cells all adopts ETPE or FEP material to process with source bottle body, gas inlet pipe and the gas steam outlet pipe of POCl3 diffuse source bottle; Make can and when operation carrying be not easy to take place slight crack and burst that the bottom of gas inlet pipe upwards is provided with the perforate section can improve the POCl3 utilization ratio.
