Abstract
The utility model relates to a printing template for preparation of crystal solar cell electrodes, solid board and aluminum alloy silk screen including mutual adhesion, the solid board has the electrode printed patterns of laser fretwork, electrode printed patterns comprises many the fretwork slits that have a narrow meshed bridging that are parallel to each other, the aluminum alloy silk screen is pasted around the solid board. The utility model has the advantages of: the utility model discloses a printing template for preparation of crystal solar cell electrodes, wherein fretwork printing template does not have the stainless steel meshwork silk like the silk screen version, only with the mechanical strength of a small amount of bridging in order to increase the fretwork version, therefore have bigger aperture efficiency and a better deinking nature, can print thinner higher more durable crystal silicon solar cell electrode grid line, thereby reduce the shading area of solar battery front electrode, the efficiency of photoelectric conversion is improved, but also because the stainless steel is difficult to warp, thereby has longer life, the present invention has a good utility value.
Description
Technical field
The utility model relates to a kind of printing stencil, is specifically related to a kind of printing stencil made for crystal solar cel electrode.
Background technology
The making of current crystal-silicon solar cell metal electrode is generally adopt the mode of serigraphy to carry out, concrete operations utilize silk-screen plate to be printed onto by metal electrode sizing on silicon chip to form certain electrode pattern, and then carry out high temperature sintering, make metal-cured and form alloy and Ohmic contact in junction and silicon chip.Wherein utilize silk-screen plate metal electrode sizing to be printed onto this step of silicon chip to be usually called in solar cell, silk-screen printing technique, and metal electrode sizing is here equivalent to the ink in other printing technologies.Silk-screen plate, except aluminum alloy frame provides support, generally comprises materials at two layers, and one deck is stainless steel wire grenadine, and another layer is the sensitive emulsion layer with printed patterns.Stainless steel wire grenadine is except being convenient to electrode slurry by except half tone, certain tension force is also provided, make half tone printing terminate can bullet from silicon chip surface, and avoid rubbing the electrode slurry being ground to and being printed on silicon chip surface, sensitive emulsion layer is then with certain pattern, to ensure certain electrode print pattern, and the thickness of printed metal electrode sizing can be regulated by its thickness, thus obtain the metal electrode of certain altitude.
But silk-screen printing technique also has himself restriction on solar cel electrode, and this is mainly reflected in: 1. the mechanical strength of silk screen is little, and easily cause damage, 2. larger electrode width causes electrode shading-area; 3. less aspect ratio result in larger resistance.Just because of the limitation of serigraphy, people wish to find a kind of simple cost effective method to prepare thinner higher crystalline silicon solar battery electrode grid line to replace serigraphy always.
Utility model content
It is high that the technical problems to be solved in the utility model is to provide a kind of mechanical strength, the printing stencil made for crystal solar cel electrode that printing effect is good.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of printing stencil made for crystal solar cel electrode, its innovative point is: comprise inter-adhesive solid panel and aluminium alloy silk screen, described solid panel has the electrode print pattern of laser hollow out, described electrode print pattern is made up of the hollow out slit with narrow meshed bridging that many are parallel to each other, and described aluminium alloy silk screen is pasted onto solid panel surrounding.
Further, the width of described hollow out slit can adjust between 0.02-50mm, and electrode slurry flows through and the bridging communicated to have multiple perpendicular allowing in the middle of this hollow out slit, bridging is evenly equipped with the aperture helping electrode slurry circulation.
Further, also stainless steel cloth is pasted with in the middle of described solid panel and aluminium alloy silk screen.
Further, described solid panel selects corrosion resistant plate, can also select aluminium sheet, zine plate, copper coin.
The utility model has the advantage of: a kind of printing stencil made for crystal solar cel electrode of the utility model, wherein hollowed printing template does not have the stainless wire mesh as silk-screen plate, only with on a small quantity with foraminate bridging to increase the mechanical strength of hollow out version, thus there is larger aperture efficiency and better deinking, thinner higher more solid crystalline silicon solar battery electrode grid line can be printed out, thus reduce the shading-area of solar cell front electrode, improve photoelectric transformation efficiency, but also because stainless steel is not easy distortion, thus there is longer service life, there is good practical value.
