Abstract
The invention discloses silicon solar cell positive silver paste of a kind of stabilization and preparation method thereof, the composition and its weight percent of the positive silver paste are：Glass powder 2% 4%, organic carrier 3% 8%, additive 1% 5%, remaining is high tap density silver powder, and the additive is made of the first dispersant, thixotropic agent, plasticiser and stabilizer.A kind of silicon solar cell positive silver paste and preparation method thereof of stabilization provided by the invention, solar cell positive silver paste stability of the present invention is high, not stratified in sealing room temperature six months, not condensate oil.
Description
Technical field
The present invention relates to silicon solar cell technologies field more particularly to a kind of silicon solar cell positive silver pastes of stabilization
And preparation method thereof.
Background technology
With a large amount of consumption of the non-renewable energy resources such as traditional energy such as coal, oil, and the environment to increasingly sharpen is dirty
The problems such as dye, is more and more prominent, and solar energy is a kind of pollution-free and inexhaustible green energy resource, increasingly by the weight of people
Depending on.Solar battery sheet is a kind of semiconductor devices that can be converted solar energy into electrical energy, by backplate, PN junction, antireflective
Film and front electrode composition.Positive silver paste by way of silk-screen printing be coated on cell piece front, by sintering curing at
For silver wire, front electrode collects electronics and external output current by the silver wire after solidification.Therefore the performance of positive silver paste
The height for determining solar battery sheet photoelectric conversion efficiency is photovoltaic industry technology development focus of attention.
Currently, silicon solar cell is usually prepared with silver powder, glass powder and organic carrier with positive silver paste.This three classes
The technical difficulty of material is more demanding, and excessive due to investing, risk is higher, and existing enterprise is difficult to research and develop these three materials simultaneously,
The selection that one such or two kinds of materials are common is researched and developed, technology common cannot bring very important matching sex chromosome mosaicism.
Positive silver paste is canned after physical mixed, interior to contain solid phase, liquid and gas.Due to the mismatch of three kinds of materials, for a long time
Phenomena such as there are spontaneous layering, condensate oils after placement causes the reliability of positive silver paste to reduce.Positive silver paste before use, through
Longer times, layering or the condensate oils such as the warehouse storage, slurry transport, the storage of cell piece manufacturing enterprise of slurry manufacturing enterprise are gone through
Positive silver paste afterwards depends merely on stirring by hand or blender stirring, and incorporation time is short, can not obtain the slurry of stable homogeneous, exist
Local enrichment.Cause that line style width is uneven, be uneven, breakpoint, imaginary point, white point, decorative pattern etc. are a series of in use
Problem seriously affects the performance of positive silver paste, and the efficiency fluctuation of silicon solar cell is made to greatly increase.It is given birth to according to cell piece
The factual survey for producing enterprise, the import silicon solar positive silver paste of mainstream has different degrees of layering, analysis on Vehicles Collected from Market
Oily phenomenon occurs, and the defect of domestic positive silver paste in this respect is more prominent.
