Description
Technical field
The present invention relates to technical field of semiconductors, particularly a kind of filter plant and filter method thereof of impure silver slurry.
Background technology
Silver slurry is by the thick slurry being mixed into of highly purified argent particulate, adhesive, solvent, cosolvent, it is for the printing of crystal silicon solar batteries positive electrode, match with backplate, electric field, play the electric energy that crystal silicon solar batteries is produced and send extraneous effect to.Positive electrode is formed by printing, oven dry and sintering by silver slurry.In the printing process of positive electrode, owing to sneaking into impurity in silver slurry, will cause occurring serigraphy substandard products, as thin grid line thickness inequality, spillage etc., even can cause the problems such as half tone explosion.These printing substandard products are done after finished product cell piece, mild degree become off standard, serious meeting becomes waste product, thereby has influence on final product percent of pass and conversion efficiency.After half tone explosion, not only cause the loss of half tone, and can cause the serious waste of silver slurry, and then increase production cost.Therefore, after impure silver slurry is recycled, re-use, can effectively improve product percent of pass, and reduce the waste of silver slurry, reduce production costs.
