Abstract
The invention relates to detergent for a silicon wafer in a solar cell system. The detergent is prepared by, by weight, 5-9 parts of potassium hydroxide, 2-7 parts of sodium carbonate, 1-3 parts of sodium silicate, 4-7 parts of citric acid, 2-5 parts of tartaric acid, 1-3 parts of coconut oil alkylolamide phosphate, 4-7 parts of fatty alcohol polyoxyethylene and 20-50 parts of water. The detergent has the advantages that the detergent is good in decontamination and cleaning performance, free of pungent smell, capable of forming a protective film on the surface of the silicon wafer, resistant to oxidation, long in service cycle, capable of effectively removing grease on the surface of the silicon wafer, metal impurities inside the silicon wafer and dust and other particles attaching to the surface of the silicon wafer and small in corrosion to the silicon wafer.
Description
Technical field
The present invention relates to solar cell system field is and in particular to a kind of silicon slice detergent in solar cell system
And its method.
Background technology
In photovoltaic and semi-conductor silicon chip production process, especially give birth in the solar silicon wafers for manufacturing solaode
During product, often there are some impurity to be attached on silicon chip surface, need silicon chip is carried out, just can obtain qualified products.
Solar silicon wafers are the bases manufacturing solaode, and its apparent condition influences whether reliability and the yield rate of battery, because
This requires higher to the surface clean of solar silicon wafers.Conventional silicon slice detergent is had due to due to formula and lacks as follows
Point: scavenging period is longer, generally requires 5-20 minute, the undesirable silicon chip surface it may appear that flower piece, that is, after cleaning of cleaning performance
Residue mottling occurs, more serious to silicon chip surface corrosion etc..
Content of the invention
In sum, in order to overcome the deficiencies in the prior art, the technical problem to be solved is to provide
The technical scheme is that the Wafer Cleaning in a kind of solar cell system
Agent, is made up of the component of following parts by weight: potassium hydroxide 5-9 part, sodium carbonate 2-7 part, sodium silicate 1-3 part, citric acid 4-7
Part, tartaric acid 2-5 part, coconutalkyl alkylolamides phosphate ester 1-3 part, aliphatic alcohol polyethenoxy 4-7 part and water 20-50 part.
A kind of manufacture method of the silicon slice detergent in solar cell system, including following making step:
(1) divide each component partly weighing following parts by weight: potassium hydroxide 5-9 part, sodium carbonate 2-7 part, sodium silicate 1-3
Part, citric acid 4-7 part, tartaric acid 2-5 part, coconutalkyl alkylolamides phosphate ester 1-3 part, aliphatic alcohol polyethenoxy 4-7 part and
Water 20-50 part；
(2) citric acid weighing step (1) and tartaric acid are added to the water dissolving, obtain a solution；
(3) potassium hydroxide, sodium carbonate and the sodium silicate weighing step (1) is added to the water dissolving, obtains b solution；
(4) the coconutalkyl alkylolamides phosphate ester weighing step (1) and aliphatic alcohol polyethenoxy add b solution, obtain
To c solution；
(5) finally by a solution and c solution mix homogeneously, obtain final product silicon slice detergent.
Further, described water is deionized water.
The invention has the beneficial effects as follows: there is good decontamination, cleaning performance, have no irritating odor, can be in silicon chip table
Face forms protecting film, antioxidation, and usage cycles are long, can effectively remove surface grease and silicon chip interior metal impurity and stick to silicon
The dust on piece surface and other granule are little to silicon slice corrosion.
