Description
Technical field
The present invention relates to solar energy photoelectric conversion glass technology for making field, particularly relate to a kind of preparation method of complex sol and make the method for packaging glass of solar cell with it.
Background technology
In secular energy strategy, solar energy power generating has prior status in many renewable energy sources such as solar energy thermal-power-generating, wind-power electricity generation, ocean power generation, biomass power generation.
In the prior art, solar photovoltaic generation system mainly is made up of solar module, and the solar energy photoelectric conversion in solar module generally all is to realize by the absorption of silicon chip to solar spectral.With the crystalline silicon solar cell modules is example, and the theoretical efficiency of sun power has only about 30 ﹪, and the laboratory top efficiency is 24.7 ﹪ at present, and what efficient was best in commercially producing is U.S. SUNPOWER company, about average 21 ﹪.At present, at the electricity conversion of silicon chip progressively under the situation near theoretical limit, raise the efficiency not only from battery preparation technique and will pay bigger cost, and it is also little to improve the space of solar battery efficiency, has been difficult to improve further.Therefore, how can improve the transmittance of packaging glass of solar cell, make more solar energy arrive silicon chip and be absorbed, thereby the photoelectric transformation efficiency of raising sun power become the emphasis problem that people paid close attention in this area.
Common, improve the transmittance of packaging glass of solar cell and can consider from the prescription and the technology of packaging glass of solar cell itself.Methods such as optically focused decorative pattern by iron level in the control raw material and increase packaging glass of solar cell surface all have been tending towards ripe on prescription and technology at present, but also are not very desirable in the raising of transmittance.
In order further to improve the transmittance of packaging glass of solar cell, can be by plating anti-reflection film on the packaging glass of solar cell surface, to reduce of the reflection loss of packaging glass of solar cell surface to sunlight, thereby improve the light utilization efficiency of solar module, then can further improve the energy conversion efficiency of solar product under low cost, this has reality and positive meaning undoubtedly.
Method at packaging glass of solar cell surface plating anti-reflection film mainly contains following three kinds at present: the one, and evaporation (vacuum) plated film; The 2nd, magnetron sputtering plating; The 3rd, the collosol and gel plated film.
Yet the stability difference of the inhomogeneous and rete of rete is the major reason that technique for vacuum coating is eliminated.And magnetron sputtering plating, be to utilize magnetron sputtering technique to carry out plated film, though can design and manufacture the complicated film of multilayer system, and can plate out multiple color on the glass substrate of white, the corrosion-resistant and wear resisting property of its rete is better, but its equipment investment cost height, production cycle is long, causes its cost that manufactures a product also higher, and cost performance does not satisfy the requirement in coated glass market, in addition, coating materials and plating piece also there is certain restriction.Collosol and gel manufactured coated glass, though its technology is simple, but its product is ornamental relatively poor, the problem that has big area membrane uniformity difference, and only limit to the preparation of laboratory sample sheet, be not easy to mass production, the product of the uniform large-area coated glass that satisfies market demands can't be provided.
Wherein, employed Coating Materials is also bigger to the final Effect on Performance of coated glass in the above-mentioned film coating method, and present employed Coating Materials mainly contains three kinds: first kind is the Coating Materials that adopts the silicon dioxide gel of conventional Prepared by Sol Gel Method; Second kind is the Coating Materials of the nano silicon of dispersiveness; The third is the nano level organic film plating material that adopts low-refraction.The shortcoming of these existing Coating Materials is: the sticking power that ⑴ can not become reconciled low-refraction effectively combines, and can not reach a best effect; ⑵ the Coating Materials of similar Prepared by Sol Gel Method is not aggregated to multiple oxide material together, can not form firm three-dimensional network, make common nanoporous anti-reflection film all stronger water-absorbent can be arranged, when causing placing the long period out of doors, its transmittance can obviously reduce.In addition, the method for preparing Coating Materials in the prior art is complicated operation not only, cycle is longer, and performance such as film forming properties is relatively poor, hardness performance and salt spray resistance is yet waited to improve, in addition, out of doors under the long-term exposure, adopt the index such as sticking power, hardness, salt spray resistance of the anti-reflection film that above-mentioned coating liquid is coated with As time goes on and constantly to reduce, can't bear long-term rugged environment.
Therefore, at deficiency of the prior art, needing badly provides the preparation method of a kind of packaging glass of solar cell plating anti-reflection film with complex sol, this preparation method's technology is simple, with low cost, and adopt this method can reduce the cost of plating Coating Materials that anti-reflection film uses greatly, further lay a good foundation for the widespread use of anti-reflection film on packaging glass of solar cell.
Also needing badly provides a kind of packaging glass of solar cell plating anti-reflection film complex sol, the Coating Materials of this complex sol does not absorb water substantially, can make the anti-reflection film of preparation keep higher transmittance, and along with the placement of time, the sticking power of anti-reflection film, hardness all has increase in various degree, thereby further reduced use cost, and the anti-reflection film prepared by this complex sol can comprise salt-fog test by all weather resisteants energy examination criterias that packaging glass of solar cell was suitable for, high temperature and humidity test, open field test, ultraviolet test, the sticking power test.
In addition, also need the manufacture method that a kind of packaging glass of solar cell is provided badly, this manufacture method is not only simple and convenient, easy handling, be applicable to big area production, and saving operational cost, improve productivity effect, the transmittance and the photoelectric transformation efficiency of the packaging glass of solar cell by this method manufacturing are all higher, the ranges of indices of refraction of antireflective coating is 1.26～1.42, thin-film refractive index was controlled at 1.38 o'clock, compared not plate the anti-reflection packaging glass of solar cell that is coated with rete and all increase more than 2.5% in 400nm～1000nm wavelength region.
