Its high manufacturing cost.At present, for reducing the cost of monocrystaline silicon solar cell and improving electricity conversion, enter
Row silicon face texturing is the most easily to realize and the most efficient method.Texture, also known as making herbs into wool, i.e. utilizes and falls into light principle, make incident illumination carry out
Multiple reflections extends its propagation path at battery surface, thus improves the solaode absorption efficiency to light.Utilize silicon
The principle of anisotropic etch, monocrystalline silicon surface can form similar pyramidal structure, effectively reduces the reflectance of sunlight.
At present, monocrystalline silicon surface texture is most commonly used that chemical corrosion method, it is common to use texture liquid be NaOH/ isopropyl
Alcohol system, but isopropanol price is high, evaporation rate is fast, and cost is high and is unfavorable for environmental protection.Patent 201010161287.8 disclosure
A kind of velvet manufacturing solution of monocrystalline silicon additive, is made up of, without isopropanol alkaline corrosion liquid and surfactant and organic acid or salt
And rapidly and efficiently, but there is the problem of reaction lack of homogeneity in it, easily cause silicon face pyramid after texture bigger than normal and
Locally the situation such as excessive erosion, need to improve further in the quality make silicon chip.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of response speed is fast, uniformity good, corrosion
The monocrystaline silicon solar cell sheet surface texture liquid containing hydrolytic collagen moderate, Reducing thickness is little, silicon chip surface quality is high and
Its preparation method.
The present invention is achieved by the following technical solutions:
A kind of monocrystaline silicon solar cell sheet surface texture liquid containing hydrolytic collagen, it is by the raw material system of following weight parts

The preparation method of a kind of monocrystaline silicon solar cell sheet surface texture liquid containing hydrolytic collagen, including following step
Rapid:
(1) weigh raw material by weight, first sodium lauryl sulphate is added in the water of 1/3-1/2 weight and stir, then delay
Slowly add styrene and the mixture of ten difluoro heptyl propyl trimethoxy silicanes and stir 0.5-1h, being finally slowly added dropwise over cure
Acid ammonium solution also stirs 2-4h in 70-80 DEG C, cools down, obtain complex emulsions after insulation 3-5h；
(2) first by hydrolytic collagen, citric acid add surplus water in 60-80 DEG C stirring 2-4h, be subsequently adding sodium hydroxide
With stirring 0.5-1h under sodium lauroyl sarcosine similarity condition, add remaining raw material stirring after cooling uniformly, obtain mixed liquor；
(3) it is slowly added to the complex emulsions in step (1) stir in the mixed liquor in step (2) and in 60-80 DEG C, mistake
The monocrystaline silicon solar cell sheet surface texture liquid containing hydrolytic collagen is i.e. obtained after filtering decontamination.
The invention have the advantage that
The present invention utilizes styrene and ten difluoro heptyl propyl trimethoxy silicane emulsions polymerization synthesis complex microsphere, can be good
Be attached to silicon chip surface, play certain etching mask effect, can reduce the excessive corrosion of silicon chip, promote reaction simultaneously
Uniformity, improves matte quality, is difficult to again remain at silicon chip surface, it is ensured that the spatter property of silicon chip；Meanwhile, by hydrolytic collagen egg
White wait raw material compounding with potentiation so as to get silicon chip texture liquid response speed very fast, corrode moderate, Reducing thickness is little, weight
Multiple utilization rate is high, and the matte pyramid size prepared is uniform, and granule is less, and batch homogeneity is good, and repeatability is high, cost
Low, environmental protection, usage safety performance is high.
