Description
Technical field
The present invention relates to solar cell, particularly a kind of solar battery back silver conductive silver paste composition and preparation method.
Background technology
Solar cell transformation efficiency and solar cell surface grid line have close relationship, and wherein, back surface grid line is generally formed by the printing of silver slurry, and different materials, comparatively large to welding performance impact, in the silver slurry used at present, for leaded slurry, there is certain destruction for environment.While maintenance weldability energy, making silver slurry not leaded, is the problem needing to solve.Internal and overseas has carried out a lot of research in this respect, some patents and report are delivered, such as: publication number is the Chinese patent of CN103000252A, document (the research information recording materials 2012,04:1 of the silicon solar cell back silver paste silver powder used such as Liu Qing).Wherein, the composition improving glass dust is the main thought of research, but the method needs modular glass powder, increases production process and manufacturing cost.After increasing sintering, grid line and silicon chip adhesion are also important want summing target in addition.It is the important approach improving adhesive force that slurry and silicon chip soak, and in the brazing process of Electronic Packaging, people often use rosin to improve wetability, and such as, publication number is the Chinese patent of CN101462209, CN101270264, CN103242745A.But these patented technologies are mostly inadequate in consideration automatically cleaning, to such an extent as to have impact on the performance of its performance.
Summary of the invention
The object of this invention is to provide a kind of silver-colored pulp material of the back of the body of unleaded solar cell conductive grid line, need prefabricated containing plumbous problem and current glass dust to solve in the silver-colored slurry of the battery back of the body in prior art, increase the problem of production process and manufacturing cost.
Technical scheme of the present invention is: a kind of solar battery back silver conductive silver paste composition, and be made up of rosin derivative, terpene blend, silver powder, nano tin dioxide, zinc acetate, potassium fluoride and cerous acetate, the mass percentage content of each component is:
Wherein, the molecular structure of described rosin derivative is:
Described terpene blend is geraniol, nerol, citronellol and the linalool mixed solvent that mixes with arbitrary proportion of totally 4 kinds of materials, preferred mass is than being geraniol: nerol: citronellol: the mixed solvent of linalool=1:2:2:1, and the molecular structure of geraniol, nerol, citronellol and linalool is respectively:
The preparation method of above-mentioned composition is: first mixed by the liquid component in composition, then adds solid constituent and stirs, then grind on grinder, finally pack.
The invention has the advantages that:
1, not leaded, environmental protection;
2, printing effect is good, and live width easily controls, and sintering range is wider, is not easy to spread in sintering process;
3, the transformation efficiency of solar cell can be made to improve 0.2 ~ 0.35%.
