The solar cell electrode comprises at least one conductive metal transition layer, wherein soldering layers are arranged on the outer side surfaces of the outermost conductive metal transition layers, and are made of tin or tin alloy materials. According to the solar cell electrode, the soldering stability of the electrode and the solder strip can be improved, and a range of a used material of the solder strip can be expanded, so that soldering is facilitated, and the cost is lowered.
Description
Technical field
The present invention relates to a kind of electrode of solar battery that facilitates welding welding, belong to technical field of solar batteries.
Background technology
At present, in solar cell processing procedure, when forming electrode, normally utilize the mode of screen printing that electrode material is printed to substrate, as shown in Figure 1, 2, in addition, when solar cell module is carried out to encapsulation procedure, conventionally can connect by welding the electrode of a plurality of solar cells, these solar cells are connected in series or in parallel, form the solar modules that meets voltage, current requirements, its electrode material adopting is generally the alloy of silver or silver-colored aluminium, and welding material base material is copper, surface-coated lead alloy or other ashbury metals; Afterwards by traditional welding procedure, for example hot air welding, infrared welding, contact type welding or laser welding form alloy by the ashbury metal on the silver electrode of battery and welding surface and link together, but, obtain if more power, when the material on welding surface is replaced by silver or silver alloy, cannot weld because eutectic point is too high with the silver of battery surface, if adopt conductive tape or conducting resinl to connect, the difficulty and the cost that greatly increase welding also can significantly be improved.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, a kind of electrode of solar battery that facilitates welding welding is provided, and it can improve the welding stability of electrode and welding, expands the scope that welding is used material, thereby convenient welding, reduces costs.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of electrode of solar battery that facilitates welding welding, comprise at least one deck conducting metal transition zone, on the lateral surface of outermost conducting metal transition zone, be provided with weld layer, and weld layer is made by tin or tin alloy material.
Further, described conducting metal transition zone is made by silver or silver alloy.
Further, the thickness of described weld layer is 3 microns ~ 50 microns.
Further, the thickness of described weld layer is 15 microns.
Further, described weld layer is made by leypewter material.
Adopted after technique scheme, because the surface of this electrode is coated with the weld layer of being made by tin or ashbury metal, the weld layer that this material is made can form alloy with a lot of materials and link together, this has just expanded the scope of welding use material, the coating material of welding just has more selection, can be leypewter, ashbury metal, silver or silver alloy etc., also improve the welding stability of electrode and welding simultaneously, avoided original welding coating material to use the relatively phenomenon of limitation, facilitate welding, reduced cost.
