Abstract
The utility model discloses an electrode structure at a right side of a crystalline silicon solar cell, comprising a crystalline silicon sheet and an electrode arranged at the right side of the crystalline silicon sheet, the electrode comprises two or more main grid lines and a plurality of auxiliary grid lines, the main grid lines are parallely arranged at equal intervals, the main grid lines are vertically connected with the auxiliary grid lines, each main grid line comprises a plurality of elliptical conductors arranged along the axial direction at equal intervals, and some of the elliptical conductors are overlapped. Under the situation that photoelectric conversion efficiency is not reduced, the electrode structure can save slurry, and can be compatible with commonly used detection machines.
Description
Technical field
The novel solar cell printing technology that relates to of this use specifically relates to a kind of crystal-silicon solar cell front electrode structure.
Background technology
The Facad structure of existing crystal-silicon solar cell, commonly by two equidistantly and parallel rectangular main grid line form with many vertical with it secondary grid lines; The group module stage will draw weldering or a plurality of solar cell pieces of some electrode holder to carry out the electricity output condition that serial or parallel connection reaches to be needed with bonding wire.How along with the price of slurry goes up day by day, when not reducing module efficient and each battery sheet efficient, the use amount that reduces slurry is the focus that solar cell manufacturer pays close attention to always.Generally overcome the above problems: need not contain silver paste, with containing silver paste and the silver slurry usable floor area that reduces front electrode less through three kinds of methods.This use is novel to be exactly the structural design through front electrode, can under the situation that does not reduce battery sheet and module photoelectric conversion efficiency, not only can save slurry, but also can be compatible with detection board commonly used.
Summary of the invention
The purpose of the utility model is exactly a kind of solar cell front electrode structure that provides to the defective of above-mentioned existence, and this structure can be saved slurry under the situation that does not reduce battery sheet and module photoelectric conversion efficiency, can also be compatible with detection board commonly used.
A kind of solar cell front electrode structure that the utility model provides; Form by main grid line and secondary grid line; Main grid line equidistance and being arranged in parallel; Vertical with secondary grid line and link together, the main grid line is two or more, and every main grid line is that a plurality of elliptic conductors are arranged and the composition of overlapping at the direction of principal axis equidistance.
Described main grid line ellipsoidal structure is 0.5mm～5mm perpendicular to the width at the wideest position of main grid line direction, and the narrowest position width is 0～5mm.
The beneficial effect of the utility model is: this front electrode structure is made up of main grid line and secondary grid line, and main grid line equidistance and being arranged in parallel is vertical with secondary grid line and link together; The main grid line is two or more; Every main grid line is that a plurality of elliptic conductors are arranged and the composition of overlapping at the direction of principal axis equidistance, can under the situation that does not reduce battery sheet and module photoelectric conversion efficiency, save slurry to greatest extent; Under the situation that does not change existing general product line equipment; Reduce production costs, improve the price advantage of product, be suitable for commercial Application.
Description of drawings:
Shown in Figure 1 is the utility model embodiment solar cell front electrode structural representation.
Among the figure, 1. secondary grid line, 2. main grid line.
Embodiment:
In order to understand the utility model better, specify the technical scheme of the utility model below in conjunction with accompanying drawing, but the utility model is not limited thereto.
Embodiment
Referring to Figure of description Fig. 1; The technical scheme of the utility model is that a kind of solar cell front electrode structure is made up of main grid line 2 and secondary grid line 1; Main grid line 2 equidistance and being arranged in parallel; Vertical with secondary grid line 1 and link together, main grid line 2 is two, and every main grid line 2 is arranged and the composition of overlapping at the direction of principal axis equidistance for a plurality of elliptic conductors.
Described main grid line 2 ellipsoidal structures are 2mm perpendicular to the width at the wideest position of main grid line 2 directions, and the narrowest position width is 0.5mm.
Adopt the solar cell front electrode structure of present embodiment; Under the situation that does not reduce battery sheet photoelectric conversion efficiency; With 5 inches monocrystalline silicon is example, if adopt 48 of secondary grid width 100um and the wideest two calculating of position 2mm of main grid, positive silver paste can be saved more than 5%.
Claims (2)
1. solar cell front electrode structure; Form by main grid line and secondary grid line; Main grid line equidistance and being arranged in parallel, vertical with secondary grid line and link together, the main grid line is two or more; It is characterized in that every main grid line is that a plurality of elliptic conductors are arranged and the composition of overlapping at the direction of principal axis equidistance.
2. a kind of solar cell front electrode structure according to claim 1 is characterized in that described main grid line ellipsoidal structure is 0.5mm～5mm perpendicular to the width at the wideest position of main grid line direction, and the narrowest position width is 0～5mm.
