Abstract
The present invention relates to a kind of crystal-silicon solar cell black silver pastes and preparation method thereof.Including metal phase, inorganic phase, organic phase and black dyes；The main component of the black dyes is aromatic sulfonic group sodium salt, and the chromogen of the black dyes includes: azo, anthraquinone triaryl methane, azine, mouth xanthenes, indigo, quinoline, phthalocyanine and nitro-imine.The black paste is applied in common blue film battery and black silion cell, optimum choice is provided for its electrode design, the battery of intimate all black can be prepared, by prepared all black battery applications in component, in addition to color difference inconsistence problems can be alleviated, the component that can be devised by all black has advanced optimized the aesthetics design of photovoltaic products.The reflection by the front electrode of silver paste production to light can also be reduced, improves the light quantity that enters of photovoltaic cell, and then improve the generated energy of photovoltaic module.
Description
Technical field
The present invention relates to area of solar cell, and in particular to a kind of crystal-silicon solar cell black silver paste and its preparation
Method.
Background technique
Efficiently, high stability, the photovoltaic cell of low cost and component always are the main pursuit of photovoltaic market, with light
The development of volt technology, market gradually appear customization design, the demand of personalized designs of photovoltaic products and by sustainable growths,
Black battery and black component are exactly differentiation in the photovoltaic products of common blue battery and blue component.
According to retrieval, present essentially black, black light-absorbing rate height increase the solar cell appearance of black silicon technology preparation
The conversion ratio of solar battery.Chinese patent CN203733821U discloses a black backboard for photovoltaic module, in
State patent CN202142558U discloses a dark border for photovoltaic module, and Chinese patent CN103131075 is disclosed
A black EVA for photovoltaic module, the appearance of these black auxiliary materials are that the design of all black battery and all black component mentions
Necessary basis is supplied.
In practice, battery is prepared even with black silicon technology, battery surface is metal electrode there is also about 5% area
It is covered, electrode zone is rendered as silver grey white, and color difference existing for battery surface electrode zone and electrodeless region constrains face
The realization of color consistency restricts the design of all black battery and all black component, the color difference of conductive silver paste and cell piece
Always exist, cause solar cell surface that waffle-like pattern is presented, when the photovoltaic module prepared is applied to architecture-integral
When, which affects the beauty of building, limits use of the photovoltaic module on architecture-integral
System.And the silver grey white of electrode district, reflectivity is higher under illumination condition, correspondingly, when the photovoltaic module prepared is applied
When on to photovoltaic plant, architecture-integral, conductive silver paste can reflect a part of light when illumination, therefore will cause a degree of
Light loss reduces the light quantity that enters of photovoltaic module, and then reduces the generated energy of photovoltaic module.
Summary of the invention
Technical problem to be solved by the present invention lies in the deficiencies for overcoming the above-mentioned prior art, provide a kind of crystalline silicon sun
Battery black silver paste and preparation method thereof and preparation method thereof.
A kind of crystal-silicon solar cell black silver paste and preparation method thereof provided by the invention, the major technique side of use
Case are as follows:
