Abstract
The present invention relates to solar cell piece technical field, especially a kind of method of welding crystalline silicon solar cell piece.A kind of method of welding crystalline silicon solar cell piece, monomer crystalline silicon solar cell piece is carried out standby after cleaning dedusting；By monomer crystalline silicon solar cell piece vertically, it is fixed using clamping device；Welding is placed on the monomer crystalline silicon solar cell piece of vertical state, and makes the lower end of welding at cell piece lower edge 5mm, and ensure that cell piece main grid is completely covered welding；Electric iron is carried out by cell piece upper edge from top to bottom to be soldered to welding lower end.The method of this welding crystalline silicon solar cell piece, avoid accumulation of the scolding tin on the Top electrode welding of solar cell, the main gate line of the cell piece in the blank interval unnecessary scolding tin being retained between Top electrode welding terminal and cell piece edge again in, the effect for extending welding is served, the stability of welding is improve.
Description
Technical field
The present invention relates to solar cell piece technical field, especially a kind of method of welding crystalline silicon solar cell piece.
Background technology
Currently manufactured solar module, it is necessary first to interconnect solar cell, it is therefore desirable in solar cell Top electrode
, be welded to the welding of welding on the bottom electrode of another solar cell piece again then by upper welding welding.In current manual welding
Electrode welding has two methods：Transverse weld method and longitudinal measure side.
Transverse weld method, is exactly that welding and solar cell are laterally disposed in welding personnel in front along main gate line direction
, and the electric iron for welding is transverse shifting in welding process.Because transverse weld method is difficult to the steady of control welding
It is qualitative, less stable.
Longitudinal measure method is exactly that welding and solar cell are placed longitudinally in welding personnel in front along main gate line direction
, and weld electric iron vertically moved in welding process.The feature of current this method be exactly by electric iron from
The upper end of cell piece is soldered to the lower end of cell piece along main gate line.Such welding method, when electric iron is moved down, melts
The scolding tin of change can be moved down with the movement of electric iron, and final unnecessary scolding tin can be deposited in the welding at solar cell edge
On.
The content of the invention
In order to overcome the shortcomings of that existing welding method can not meet use demand, the invention provides one kind welding crystal
The method of silicon solar cell piece.
The technical solution adopted for the present invention to solve the technical problems is：A kind of side of welding crystalline silicon solar cell piece
Method,
A, monomer crystalline silicon solar cell piece is carried out it is standby after cleaning dedusting；
B, by monomer crystalline silicon solar cell piece vertically, be fixed using clamping device；
C, welding is placed on the monomer crystalline silicon solar cell piece of vertical state, and makes the lower end of welding under cell piece
At edge 5mm, and ensure that cell piece main grid is completely covered welding；
D, electric iron is carried out by cell piece upper edge from top to bottom to be soldered to welding lower end.
According to another embodiment of the invention, further include, during welding, in advance clean out electric soldering iron tip,
Ensure welding stability, after electric Lip river iron temperature is risen into 360-400 DEG C, welding is proceeded by after keeping temperature stabilization.
The beneficial effects of the invention are as follows the method for this welding crystalline silicon solar cell piece, it is to avoid scolding tin is in sun electricity
Accumulation on the Top electrode welding in pond, and unnecessary scolding tin is retained in the sky between Top electrode welding terminal and cell piece edge
In the main gate line of the cell piece between white area, the effect for extending welding is served, reduced by scolding tin is piled up to cell piece institute shape
Into stress, while also improve the stability of welding to a certain extent.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is this practical invention operation chart.
Specific embodiment
A kind of method of welding crystalline silicon solar cell piece,
A, monomer crystalline silicon solar cell piece is carried out it is standby after cleaning dedusting；
B, by monomer crystalline silicon solar cell piece vertically, be fixed using clamping device；
C, welding is placed on the monomer crystalline silicon solar cell piece of vertical state, and makes the lower end of welding under cell piece
At edge 5mm, and ensure that cell piece main grid is completely covered welding；
D, electric iron is carried out by cell piece upper edge from top to bottom to be soldered to welding lower end.
During welding, electric soldering iron tip is cleaned out in advance, it is ensured that welding stability, electric Lip river iron temperature is risen into 360-
After 400 DEG C, welding is proceeded by after keeping temperature stabilization.
It is described above to be merely exemplary for the purpose of the present invention, and it is nonrestrictive, and those of ordinary skill in the art understand,
In the case where the spirit and scope that appended claims are limited are not departed from, many modifications, change or equivalent can be made, but all
To fall within the scope of protection of the present invention.
