Description
Technical field
The utility model relates to crystal silicon solar photovoltaics to utilize technical field, in particular to a kind of to be used for regular hexagon too
The grid line halftone of positive energy cell piece.
Background technique
With current energy shortage, environmental degradation, photovoltaic power generation application is received significant attention, and have developed rapidly.Photovoltaic at present
Industry is mainly based on 125 × 125 and 156 × 156 square battery piece and its component, and regular hexagonal solar cell piece
Production, can reduce the waste of silicon rod, increase the surface area of cell piece, reduce cost, improve the output power of cell piece, just
The cell piece component that hexagon solar battery sheet is equipped with, it is seamless spliced, the confined space is made full use of, can satisfy cell piece group
Part sliver, welding or lamination need.The regular hexagon cell piece full wafer series welding parallel connection of existing patent disclosure is equipped with battery component, but
There is not the relevant report of regular hexagon cell piece and its design of sliver halftone.
Utility model content
The technical problems to be solved in the utility model is to overcome deficiency in the prior art, is provided a kind of for positive six side
The grid line halftone of shape solar battery sheet.
In order to solve the technical problem, the solution of the utility model is:
A kind of grid line halftone for regular hexagonal solar cell piece, including main grid hole, thin gate hole and backgate hole are provided；
Halftone is regular hexagon, and the main grid hole on halftone is arranged by following two form:
Front gate line halftone symmetrical several main grid holes in a longest diagonal line two sides wherein, main grid hole direction with most
Long-diagonal is parallel；Or front gate line halftone is by wherein longest diagonal line and by the diagonal line midpoint and normal thereto
Lines are divided into four parts, and several main grid holes are symmetrically arranged in each section, and each main grid hole is not connected to mutually；
On front gate line halftone, a plurality of thin gate hole is equipped with perpendicular to main grid hole；It is corresponding in main grid hole on the grid line halftone of the back side
Position is equipped with backgate corresponding with main grid hole number hole.
As an improvement sharp end is designed at main grid hole both ends, for reducing printing slurry.
As an improvement main grid hole width is 1.5mm.

Compared with prior art, the utility model has the beneficial effects that
The utility model halftone applies to regular hexagonal solar cell piece, carries out being screen printed onto cell piece surface and
Existing grid line can satisfy regular hexagon cell piece difference sliver and welding needs, improve the output power of cell piece.
Detailed description of the invention
Fig. 1 is the utility model one of which structural schematic diagram.
Fig. 2 is the utility model another kind structural schematic diagram.
Marked in the figure: main grid hole 1, thin gate hole 2, backgate hole 3.
Specific embodiment
Embodiment below can make the technical staff of this professional skill field more fully understand the utility model, but not
The utility model is limited in any way.
In the utility model, a kind of grid line halftone for regular hexagonal solar cell piece, including main grid hole 1, thin grid
Hole 2 and backgate hole 3.Halftone is regular hexagon, and the gate hole on halftone is arranged by following two form:
Such as Fig. 1, front gate line halftone symmetrical 6 main grid holes 1 in a longest diagonal line two sides wherein, main grid hole 1
Direction is parallel with longest diagonal line, and sharp end is designed at 1 both ends of main grid hole, for reducing printing slurry.Perpendicular to 1 side of main grid hole
To equipped with a plurality of thin gate hole 2.On the grid line halftone of the back side, in 1 corresponding position of main grid hole, it is equipped with 6 backgate holes 3.
Or such as Fig. 2, front gate line halftone is by a wherein longest diagonal line and the process diagonal line midpoint and normal thereto
Lines be divided into four parts, is symmetrically arranged with 3 main grid holes 1 in longest diagonal line two sides in each section, each main grid hole 1 is mutually not
Connection, sharp end is designed at 1 both ends of main grid hole, for reducing printing slurry.A plurality of thin gate hole is equipped with perpendicular to 1 direction of main grid hole
2.On the grid line halftone of the back side, in 1 corresponding position of main grid hole, it is equipped with backgate corresponding with 1 quantity of main grid hole hole 3.
Wherein, 1 width of main grid hole is 1.5mm, and thin 2 width of gate hole is 80~100 μm, and 3 width of backgate hole is 1.5mm.
Therefore, the actual range of the utility model not only includes the disclosed embodiments, further include claims it
Under be practiced or carried out all equivalent schemes of the utility model.
