Description
Technical field
The invention belongs to the electrocondution slurry field, relate in particular to a kind of glass powder and preparation method thereof, and the electrocondution slurry that adopts this glass powder preparation.
Background technology
The front and back electrocondution slurry of used for solar batteries is generally all formed by preparation of raw material such as metal powder, glass powder and organic carriers.With the conductive silver paste is example, and glass powder is in high temperature melting, with the sunshine antireflection layer of silicon face (normally SiNx or TiO
2Film) melt, the silver in the slurry can be contacted with silicon face, and silver powder can form Ag/Si conduction island with silicon during high temperature under the effect of glass powder, silver-colored lead and silicon can form good Ohmic contact; Simultaneously, attached to silicon chip surface, the island that will conduct electricity links together glass binder with silver powder, forms fine and close uniform conductive film, this shows that glass powder is the important component part in the electrocondution slurry.
In the prior art, the glass powder prescription mainly is to be matrix with the oxide compound, like plumbous oxide, silicon oxide, boron oxide etc.; If directly oxide compound is mixed, because in preparation solar battery sheet process, sintering temperature is not high; Have only 800-900 ℃, can't become whole uniformly by molten sintering between the various oxide compounds, just do not reach the effect of glass powder; So need the compound form that makes various oxide compound fusions after the high temperature melting and form glass powder earlier, like lead borosilicate etc., the back composition that quenches is even; Just can reach the effect of glass powder, so that further use.
Therefore, the method for existing glass powder formulation glass powder generally comprises following step:
(1) with all raw material thorough mixing;
(2) mixed compound is put into crucible, put into electric furnace then and be incubated for some time;
(3) glass metal after will melting is poured in the cold water and is quenched;
(4) sheet or granular glass and raw material are put into the ball mill ball milling together;
(5) glass powder behind the ball milling is sieved pack.
This method steps is loaded down with trivial details, and high-temperature operation is dangerous big, takes time and effort.
