Abstract
The utility model provides a printing stencil for multi-section grating distribution. The printing stencil for multi-section grating distribution comprises a metal support silk screen and a photosensitive emulsion layer which covers the metal support silk screen. The photosensitive emulsion layer is provided with main grating grooves and auxiliary grating grooves. The main grating grooves include a plurality of main grating segmental grooves on a same line, gaps are reserved between adjacent main grating segmental grooves, two ends of each main grating segmental groove are rounded, and the auxiliary grating grooves are connected with the main grating segmental grooves. The main grating grooves include the main grating segmental grooves on the same line, the gaps between the main grating segmental grooves allow consumption of silver paste to be decreased in printing, and accordingly cell cost is decreased.
Description
Technical field
The utility model relates to the solar cell print system, particularly, relates to the printing stencil of arranging for the multisection type grid line.
Background technology
The photovoltaic panel assembly is that a kind of exposure just can produce galvanic TRT in the sun, and the solid photovoltaic cell of basically mainly making with semiconductor material (for example silicon) forms, and comprises P-type semiconductor and N-type semiconductor.P-type semiconductor (P refers to positive, positively charged): mix a small amount of triad by monocrystalline silicon by special process and form, can be in the inner hole that forms positively charged of semiconductor; N-type semiconductor (N refers to negative, and is electronegative): mix a small amount of pentad by monocrystalline silicon by special process and form, can be at the electronegative free electron of the inner formation of semiconductor.
When light frequency surpasses a certain limiting frequency, be subjected to light-struck solar panel surface photoelectron of will overflowing immediately, photoelectric effect occurs.When adding a closed circuit in the solar panel outside, add the forward power supply, the photoelectron of these effusions all arrives anode and just forms so-called photoelectric current.Be positioned at the grid line of solar battery front side formally for the enrichment electric charge.
Main grid line in the electrode pattern that stencilization of the prior art goes out is a continuous straightway, the large usage quantity of its silver paste, and shading-area is larger.
The utility model content
For defective of the prior art, the purpose of this utility model provides a kind of printing stencil for multisection type grid line layout.
According to an aspect of the present utility model, a kind of printing stencil for multisection type grid line layout is provided, comprise metallic support silk screen, sensitive emulsion layer, described sensitive emulsion layer is covered in described metallic support silk screen, described sensitive emulsion layer is provided with main grid wire casing, secondary grid line groove, wherein, described main grid wire casing comprises a plurality of main grid line segment grooves that are located along the same line, there is the gap between the adjacent described main grid line segment groove, the two ends of described main grid line segment groove are fillet structure, and described secondary grid line groove connects described main grid line segment groove.
Preferably, the described secondary grid line groove that is connected to the two ends place of described main grid line segment groove is radiated entends.
Preferably, the length of described main grid line segment groove is identical.
Preferably, be equally spaced between the main grid line segment groove that is located along the same line.
Preferably, also comprise the supplementary gate wire casing, wherein, connect by the supplementary gate wire casing between the adjacent main grid line segment groove that is located along the same line.
Main grid wire casing of the present utility model comprises a plurality of main grid line segment grooves that are located along the same line, the gap between the adjacent main grid line segment groove so that the silver slurry consumption in when printing reduce, thereby reduced the cost of cell piece.
