Abstract
The invention relates to the field of solar cells, and discloses an organic silicon primer liquid and a dual-glass assembly, wherein the organic silicon primer liquid contains vinyl hydroxyl silicone oil and a silicon nitrogen compound; the invention discloses a dual-glass assembly, which comprises: the solar cell module comprises a first glass layer, a first packaging layer, a cell module layer, a second packaging layer and a second glass layer which are sequentially stacked, wherein a light-reflecting coating is arranged on one side, facing the cell module layer, of the second glass layer; the side of the first glass layer facing the battery cell stack layer is provided with an organic silicon base coating layer, and the organic silicon base coating layer is obtained by first curing the organic silicon base coating liquid provided by the invention. In addition, in the preparation process of the dual-glass assembly, the primer is cured in an open environment, so that small molecular structural substances are fully released, and residues cannot be generated in the dual-glass assembly.
Description
Technical Field
The invention relates to the field of solar cells, in particular to an organic silicon primer solution and a dual-glass assembly.
Background
The storage capacity of traditional energy sources such as petroleum is limited, the traditional energy sources are consumed in a large amount, and the environment is seriously polluted, so that clean energy sources such as wind energy and solar energy become the development trend of the existing energy sources, particularly, the solar energy is less limited by regions, and the energy sources are rich, thereby becoming a hotspot of research.
The solar cell module is a core component of the solar cell, is excellent in performance, can effectively improve the performance of the solar cell, has high requirement on sealing performance, and seriously influences the performance of the cell due to uneven thickness and pores of bubbles and a binder. The packaging technology of solar cell modules attracts attention of researchers.
The organic silicon rubber is a packaging material which is widely applied at present, but the surface energy of the organic silicon rubber is very low, and the secondary valence bond formed with a glass substrate is very weak, so the tackifying effect is realized by adding a tackifying auxiliary agent. In the prior art, an epoxy group serving as a tackifying assistant is added into a silica gel system, and the epoxy group and a base material form chemical combination to achieve the purpose of increasing the bonding strength, but the tackifying assistant can achieve a better tackifying effect only by needing a higher heating curing temperature, and the tackifying effect is not obvious at a lower temperature. The adhesion promotion auxiliary agent containing alkoxy groups is also used, for example, methoxy groups or ethoxy groups are introduced into a silica gel system, and can be chemically combined with a substrate through the alkoxy groups at a lower temperature so as to achieve the purpose of increasing the bonding strength, but the adhesion promotion auxiliary agent achieves the purpose of chemically combining through the reaction of the alkoxy groups and hydroxyl groups, small molecular substances such as methanol or ethanol and the like can be generated in the process, and the residual methanol or ethanol brings serious adverse effects on a sealing structure for packaging a solar cell.
Therefore, it is desirable to develop an encapsulant that is beneficial for improving the performance of the solar cell, so as to eliminate the defects of the encapsulant.
Disclosure of Invention
Aiming at the defect that the packaging material provided by the prior art is not beneficial to packaging of the solar cell, the invention provides a novel organic silicon primer solution and a dual-glass assembly. The organic silicon primer solution provided by the invention can realize a better bonding effect at a lower temperature, and the dual-glass assembly provided by the invention overcomes the adverse effect caused by the residue of small molecular substances in the existing packaging method.
In order to achieve the above object, the present invention provides a silicone primer solution containing a vinyl hydroxy silicone oil and a silicon nitrogen compound.
The invention provides a dual glass assembly, which comprises: the solar cell module comprises a first glass layer, a first packaging layer, a cell module layer, a second packaging layer and a second glass layer which are sequentially stacked, wherein a light-reflecting coating is arranged on one side, facing the cell module layer, of the second glass layer; the side of the first glass layer facing the battery cell stack layer is provided with an organic silicon base coating layer, and the organic silicon base coating layer is obtained by first curing the organic silicon base coating liquid provided by the invention.
The inventor of the invention discovers in the research process that the photovoltaic packaging assembly in the prior art can achieve a good tackifying effect only by adding the tackifying auxiliary agent into the transparent liquid silicone rubber main body and using an epoxy group as the tackifying auxiliary agent at a high heating and curing temperature, and the tackifying effect is not obvious at a low temperature; the alkoxy group such as methoxy group or ethoxy group as the adhesion promoter can form chemical bonding with the substrate through the alkoxy group at a relatively low temperature to achieve the purpose of increasing the bonding strength, but the adhesion promoter achieves the purpose of chemical bonding by utilizing the reaction of the alkoxy group and the hydroxyl group, small molecular substances such as methanol or ethanol are generated in the process, and the residual methanol or ethanol has a very serious adverse effect on the sealing structure of the dual-glass component.
The inventor of the present invention has found through research that the adhesion strength can be increased by adding a primer layer instead of adding a tackifier to the main body of the transparent liquid silicone rubber, and the above-mentioned drawbacks can be overcome.
