Abstract
The invention discloses a kind of optics of liquids silica-gel composition and preparation method thereof, the optics silica gel formed by the optics of liquids silica-gel composition and using the solar cell module of the optics silica gel, the optics of liquids silica-gel composition contains vinyl silicone oil, crosslinking agent, catalyst, inhibitor, light conversion material, optional tackifier and optional reinforcing agent, and the light conversion material is benzoxazoles type light conversion material.Higher light transmission rate can not only be kept with optics silica gel prepared by optics of liquids silica-gel composition of the invention, and the ultraviolet light that can be will transmit through is converted to visible light, i.e. the present invention introduces light conversion material in silica gel, the lower ultraviolet light of quantum efficiency in crystal silicon cell can be converted to the higher visible light of quantum efficiency, and finally improve the photoelectric conversion efficiency of solar battery.
Description
Technical field
The present invention relates to a kind of optics of liquids silica-gel compositions and preparation method thereof, and the invention further relates to a kind of optics silica gel
And the solar cell module using the optics silica gel.
Background technique
Solar battery can be converted solar energy into electrical energy using its photovoltaic effect, with it is environmentally protective, take no
Advantage nexhaustible to the greatest extent, is a kind of important development direction of alternative conventional gas and oil energy.Solar battery generally can be divided into
Crystal silicon solar energy battery, thin-film solar cells, dye-sensitized solar cells and organic solar batteries.Wherein, pass through
The research and development and marketing of many years, crystal silicon solar energy battery gradually occupies predominantly in area of solar cell at present
Position.
Usually, the preparation method of crystal silicon solar energy battery include by sheet glass, transparent EVA glue film, cell piece,
EVA adhesive film and backboard are successively stacked together and carry out hot-forming.
For relative eva glue film, liquid silica gel material has better weatherability, especially UV resistance, therefore,
New development and application is obtained in photovoltaic art.
Summary of the invention
The purpose of the present invention is to provide a kind of optics of liquids silica-gel composition, which is not only protected
Higher light transmission rate has been held, and visible light can be converted ultraviolet light into, has improved the photoelectric conversion efficiency of component.
According to the first aspect of the invention, the present invention provides a kind of optics of liquids silica-gel composition, the composition contains
There are vinyl silicone oil, crosslinking agent, catalyst, inhibitor, light conversion material, optional tackifier and optional reinforcing agent, institute
Stating light conversion material is benzoxazoles type light conversion material, and at least partly vinyl silicone oil is the first vinyl silicone oil, described the
The viscosity of one vinyl silicone oil is 10000-150000cP.
According to the second aspect of the invention, the present invention provides optics of liquids silica gel described in first aspect of the present invention
The preparation method of composition, method includes the following steps:
(1) in organic solvent by light conversion material dissolution, after being optionally filtered, light conversion material solution is obtained；
(2) the light conversion material solution is mixed at least partly vinyl silicone oil, and removed in obtained mixture
Organic solvent, obtain vinyl silicone oil mixture；
(3) by vinyl silicone oil mixture and remainder vinyl silicone oil, crosslinking agent, catalyst, inhibitor, optional
Tackifier and optional reinforcing agent mixing, obtain optics of liquids silica-gel composition.
According to the third aspect of the present invention, the present invention provides a kind of optics silica gel, which is will be of the invention
Obtained from optics of liquids silica-gel composition described in first aspect is solidified.
According to the fourth aspect of the present invention, the present invention provides a kind of solar cell module, the solar battery groups
