Abstract
The invention discloses a kind of aluminum paste composition for solar cell, content is by component by mass percentage: acrylic resin derivative is 5～10%, and mixed solvent is 10～15%, and aluminium powder is 64～80%, and glass dust is 3-10%, and coupling agent KH570 is 1% composition. The present invention can improve solar conversion efficiency 0.2-0.35%.
Description
Technical field
The invention belongs to technical field of solar, relate to a kind of aluminium paste, more specifically relate to a kind of aluminum paste composition for solar cell.
Background technology
There is close relationship in the hole that solar conversion efficiency and solar energy back aluminum slurry are removed impurity efficiency and formation, and wherein, silicon chip back side aluminium is generally starched printing-sintering by silver and formed. And different material compositions has great impact to solar energy conversion ratio. For obtaining more large effective area and optoelectronic transformation efficiency, so far, carry out various trials and invention, still, removing Shortcomings still aspect impurity and formation hole. For example, forming hole is all inorganic matter, as the oxide of aluminium and boron element, is unfavorable for being diffused into crystalline silicon inside, forms effective PN junction, has reduced the transformation efficiency of solar energy, is the technical issues that need to address.
Summary of the invention
The object of the invention is to form for solving existing PN the technical barrier existing in hole, provide a kind of organic resin self that B element can be provided, and easily form the resin in hole and easily disperse, wetting, with the composition of the close aluminium paste of the crystalline silicon coefficient of expansion.
For achieving the above object, the technical solution adopted in the present invention is:
For an aluminum paste composition for solar cell, content is by component by mass percentage: acrylic resin derivative is 5～10%, and mixed solvent is 10～15%, and aluminium powder is 64～80%, and glass dust is 3-10%, and coupling agent KH570 is 1% composition. Wherein, the molecular structure of described acrylic resin derivative is:
Described acrylic resin derivative is hydroxy-ethyl acrylate monomer, form to dimethyl boron styrene monomer with methyl methacrylate monomer copolymerization, the mass ratio of copolymerization is: hydroxy-ethyl acrylate monomer: to dimethyl boron styrene monomer: methyl methacrylate monomer=20:1:30. Adopt polymerisation in bulk, initator is dicumyl peroxide, and polymer temperature is 120 degree, and the reaction time is 15 as a child dischargings.
Described mixed solvent refers to cyclohexanone, butyl acetate mixed solvent, and the mass ratio of its mixed solvent is: cyclohexanone: butyl acetate=10:3.
Described glass dust is for according to mass ratio to be: PbO2:ZnO:SiO2=30:5:14 sintering forms.
The preparation method of a kind of aluminum paste composition for solar cell of the present invention is:
Each component in composition is placed in reactor according to formula rate mix, stir after packaging obtain composition.
Advantage and the beneficial effect of a kind of aluminum paste composition for solar cell of the present invention:
