Abstract
The invention discloses a kind of methods for repairing cell piece oxidation using electrical pumping equipment, arrange firstly, oxide cell piece is sorted；The oxide cell piece sub-elected is arranged again, stacking is put into electrical pumping carrier；Finally, the reverse current using electrical pumping equipment injects station, surface metal ion activation is carried out to oxide cell piece, completes to repair cell piece oxidation.This can efficiently repair cell piece oxidation using the method that electrical pumping equipment repairs cell piece oxidation, while will not bring other unfavorable conditions again.
Description
Technical field:
The present invention relates to area of solar cell, are especially a kind of side that cell piece oxidation is repaired using electrical pumping equipment
Method.
Background technique:
It will receive such environmental effects in solar battery storage process, cause the slow oxygen of battery slice surface metal electrode
Change, the cell piece of oxidation will lead to electrical performance of cell decaying and the decline of electrode solderability, use reliably to influence cell piece
Property.
Electrical pumping is generally using equipment during manufacturing, and main effect is by electrical pumping equipment reverse current
Station is injected, eliminates that reduce too can crystal defect inside cell piece.
Currently, the common method for repairing cell piece oxidation is by oxide cell piece, monolithic is sequentially placed into sintering furnace and carries out
Double sintering.But cell piece double sintering will lead to cell piece power generation performance and be decreased obviously, and there is also Al-BSF bulge etc.
Problem of appearance, while monolithic sintering operation low efficiency and will appear cell piece breakage.
Summary of the invention:
The technical problem to be solved by the invention is to provide a kind of sides that cell piece oxidation is repaired using electrical pumping equipment
Method can efficiently repair cell piece oxidation, while will not bring other unfavorable conditions again.
The technical solution of the invention is as follows, provides a kind of method for repairing cell piece oxidation using electrical pumping equipment, first
First, oxide cell piece is sorted and is arranged；The oxide cell piece sub-elected is arranged again, stacking is put into electrical pumping carrier；
Finally, the reverse current using electrical pumping equipment injects station, surface metal ion activation is carried out to oxide cell piece, completes to repair
Multiple cell piece oxidation.
It is not needed at monolithic using after the above technology compared with prior art, the invention has the following advantages that stacking technique
Reason is completed, and it is obvious to repair oxidative function effect.It and is not in former sintering furnace reparation oxidation electricity during repairing oxidation
The method of pond piece, the problem of appearance such as brought electrical property decline and Al-BSF bulge.
Specific embodiment:
With regard to specific embodiment, the invention will be further described below:
A method of using electrical pumping equipment repair cell piece aoxidize, firstly, by the longer cell piece of storage time into
The sampling observation of row quality, the cell piece for occurring battery slice surface metal anodizing during sampling observation are sorted；Again sub-electing
Oxide cell piece arrange, neat stacking is put into electrical pumping carrier；Finally, the reverse current using electrical pumping equipment injects
Station carries out surface metal ion activation to oxide cell piece, completes to repair cell piece oxidation.
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.
