Description
Technical field:
The utility model relates to the crystal-silicon solar cell production technical field, what be specifically related to is a kind of printing stencil that is used for manufacturing crystalline silicon solar battery electrode.
Background technology:
The making of crystal-silicon solar cell metal electrode at present generally is to adopt the method for silk screen printing to carry out, concrete operations are to utilize the silk screen version that metal electrode sizing is printed onto the certain electrode pattern of formation on the silicon chip, and then carry out high temperature sintering, make metal-cured and form alloy and ohmic contact at junction and silicon chip.Wherein utilize the silk screen version that metal electrode sizing is printed onto this committed step of silicon chip and usually be called silk-screen printing technique in the solar cell, and the metal electrode sizing here is equivalent to the printing ink in other printing technology.The silk screen version generally comprises two layers of material except aluminum alloy frame provides support, one deck is the stainless steel wire grenadine, and another layer is for having the sensitive emulsion layer of printed patterns.The stainless steel wire grenadine also provides certain force of strain except being convenient to electrode slurry by the half tone, make half tone can bullet after printing finishes from silicon chip surface, be ground to the electrode slurry that is printed on the silicon chip surface and avoid rubbing.Sensitive emulsion layer then has certain pattern, guaranteeing certain electrode printed patterns, and can regulate the thickness of printed metal electrode sizing by its thickness, thereby obtains the metal electrode of certain altitude.
Silk screen printing is in the advantage of preparation aspect the solar cel electrode that its technology is simple, low-cost, high yield and equipment increasingly automated, be that other method is difficult to comparison in these areas.But silk-screen printing technique also has the restriction of himself on solar cel electrode, and this is mainly reflected in: 1. bigger electrode width causes bigger electrode shading area; 2. less depth-width ratio has caused bigger electrode resistance.The minimum widith of the crystalline silicon solar battery electrode of silk screen printing is decided by the width of mesh of stainless steel wire grenadine.At present, the electrode minimum dimension of the crystal-silicon solar cell of silk screen printing about 100-110 μ m, through behind the oversintering height about 15 μ m.This makes the average conversion efficiency of solar cell between 17.0%-17.5%, with laboratory highest level 24.75% bigger difference is arranged.When the width that requires metal electrode further reduces (for example being reduced to below the 100 μ m), the phenomenon of the gate electrode line fracture that causes will unavoidably appear stopping up owing to the silk screen version in silk screen printing, and this makes and utilizes method for printing screen to be difficult to prepare more meticulous solar cell metal electrode grid line.Just because of the above-mentioned limitation of silk screen printing, people wish to find a kind of simple, cost effective method to replace silk screen printing and prepare thinner higher crystalline silicon solar battery electrode grid line always.
The utility model content:
The purpose of this utility model provides a kind of printing stencil that is used for manufacturing crystalline silicon solar battery electrode, and it can overcome the shortcoming of screen printing screens, and prints out thinner, higher, more solid crystalline silicon solar battery electrode grid line.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises corrosion resistant plate 1, aluminum alloy frame 2, printed patterns 3, hollow out slit 4 and bridging 5; Be wrapped with aluminum alloy frame 2 around the corrosion resistant plate 1, printed patterns 3 is carved with in the centre position of corrosion resistant plate 1, and printed patterns is made up of hollow out crack 4 and bridging 5.
The thickness of described corrosion resistant plate 1 is between 0.02mm-2mm; Aluminum alloy frame 2 is that the length of side is the square body of 320mm.
Therefore the utility model, has longer useful life because adopt the more difficult distortion of corrosion resistant plate, and it can directly apply to existing screen process press, carries out the printing of crystalline silicon solar battery electrode slurry, has better practicability.And can print out thinner, higher, more solid crystalline silicon solar battery electrode grid line, thus reduce the shading area of solar cell front electrode, improve photoelectric conversion efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the connection diagram of the utility model hollow out version.
Embodiment:
Referring to Fig. 1-2, this embodiment is by the following technical solutions: it comprises corrosion resistant plate 1, aluminum alloy frame 2, printed patterns 3, hollow out slit 4 and bridging 5; Be wrapped with aluminum alloy frame 2 around the corrosion resistant plate 1, printed patterns 3 is carved with in the centre position of corrosion resistant plate 1, and printed patterns is made up of hollow out crack 4 and bridging 5.
The thickness of described corrosion resistant plate 1 is between 0.02mm-2mm; Aluminum alloy frame 2 is that the length of side is the square body of 320mm.
Therefore this embodiment, has longer useful life because adopt the more difficult distortion of corrosion resistant plate, and it can directly apply to existing screen process press, carries out the printing of crystalline silicon solar battery electrode slurry, has better practicability.And can print out thinner, higher, more solid crystalline silicon solar battery electrode grid line, thus reduce the shading area of solar cell front electrode, improve photoelectric conversion efficiency.
