Abstract
The utility model discloses a crystalline silica solar cell main electrode, which is characterized in that the main electrode possesses a hollow structure with segments. The frame width at the hollow segment of the main electrode is larger than 0.1 mm. In the crystalline silica solar cell main electrode provided in the utility model, because the hollow structure with segments is employed, the slurry application amount can be reduced, and the cell cost can be reduced; because the surface composite area is decreased, the cell performance is enhanced to a certain degree; and because the profile of the main electrode is the same to the traditional electrode, the assembly welding material can be directly used without any change.
Description
Technical field
The utility model relates to a kind of electrode of crystal silicon solar energy battery, relates to a kind of crystal silicon solar energy battery main electrode specifically.
Background technology
The solar battery front side main electrode of silk screen printing at present, its structure that adopts has two kinds of shapes (like Fig. 1,2): tip main electrode and tack main electrode.Such main electrode structure can be so that electrical property be more stable, and has obtained being widely used.But kind electrode because employing is solid, uses the Ag slurry more.Along with the rising of Ag slurry price and to the control of production cost, more and more require under the prerequisite that does not influence electrical property and weldability, to reduce the number to be printed of slurry as far as possible, improve the performance of battery simultaneously as much as possible.
The utility model content
The utility model problem to be solved is, overcomes the defective that prior art exists, and a kind of crystal silicon solar energy battery main electrode is provided; The gabarit of main electrode is identical with existing electrode; Its inner part hollow design that adopts, then electrical property and weldability can not be affected and reducing owing to the surface printing area to guarantee certain border width; Corresponding surface recombination area reduces, and electrical property is had certain contribution.
A kind of crystal silicon solar energy battery main electrode of the utility model is characterized in that: main electrode is the segmentation hollow structure.
Said main electrode hollow part border width is greater than 0.1mm.
The utility model crystal silicon solar energy battery main electrode, owing to adopt the segmentation hollow structure, the use amount of slurry can reduce, the battery cost reduces; Because the surface recombination area reduces, battery performance has certain lifting; Because the electrode profile is identical with traditional electrode, need not carry out any change to the assembly welding material and just can directly use.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Like Fig. 3, shown in 4, a kind of crystal silicon solar energy battery main electrode of the utility model, main electrode 1 is the segmentation rectangular hollow structure, promptly has some rectangles cavity on the main electrode.Said main electrode hollow part frame 2 width are greater than 0.1mm.
The scope of application of the utility model: be applicable to various crystal silicon battery.Require and the technology matching principle according to the different electric pool structure, the quantity of the main electrode of battery sheet can be designed to the 2-10 root and not wait, and the change width scope of main electrode is 1-3mm.The segmented mode of every main electrode and ratio can be adjusted according to reality test and welding requirements, minimumly are divided into 2 sections.The utility model goes for the electrode structure that variety of way is made, like plating, vapor deposition, sputter etc.
