Description
Technical field
A kind of electrode of solar battery mask to print version and manufacturing approach thereof that the utility model relates to belong to the solar cell print field.
Background technology
Serigraphy is that silk fabrics, synthetic fabrics or woven wire are stretched tight on screen frame, adopts manual method of carving paint film or photochemistry plate-making to make screen printing forme.Modern screen printing technique then is to utilize photosensitive material to make screen printing forme (making the silk screen hole of picture and text part on the screen printing forme is through hole, and the silk screen hole of non-graphic part is plugged) through photomechanical method.Through the extruding of scraper plate, printing ink is transferred on the stock through the mesh of picture and text part during printing, formed the picture and text the same with original copy.Screen printing apparatus is simple, easy to operate, and it is simple and easy and with low cost to print, make a plate, and adaptability is strong.
Serigraphy originates from China the earliest, apart from modern existing more than 2,000 year history.Folder a word used in person's names printing method has just appearred period as far back as the Qin Han of Ancient Times in China.Generally popular to the Eastern Han Dynasty folder a word used in person's names batik method, and the level of printed product also has raising.To the Sui Dynasty great cause, people begin to carry out stamp with the frame of the tulle that stretches tight, and make folder a word used in person's names printing technology develop into screen printing.According to history records records, the exquisite dress ornament of wearing in the imperial palace during Tang Dynasty just has to be printed in this way.To the Song dynasty serigraphy development has been arranged again, and improved the oil paint of original use, beginning adds the rubber powder of starch based in dyestuff, make it become slurry and carry out serigraphy, makes the color of serigraphy product more gorgeous.
Screen printing is a big utility model of China.U.S.'s " serigraphy " magazine had such commentary to Chinese screen printing technique: " prove that on evidence Chinese just used horse-hair and template in the past in bimillennium.The uniforms card at Ming Dynasty's initial stage is understood their competitive spirit and process technology." utility model of screen printing, promoted the development of the human material progresses in the world.Today after bimillennium, screen printing technique constantly develops perfect, has become an indispensable part among the human lives at present.
Serigraphy not only adapts to general paper printing, and adaptability is very extensive.For example: pottery, glass, printed substrate etc.Quality according to stock is different, just is not quite similar during printing, though inseparable inner link is arranged between each series, because of stock quality different (being that chemical property is different with physical property), its particularity is separately arranged again separately.So people are divided into by the stock difference usually: several big type of the printing of paper class, the printing of plastics class, ceramic-like printing, category of glass printing, wiring board printing, metal species printing, textile printing etc.So just formed relatively independent print system separately.
One of process for manufacturing circuit board; Be on the screen cloth of existing negativity pattern; Scrape with scraper and to extrude an amount of printing ink (promptly hindering agent), see through local screen cloth and form positive pattern, printing on the smooth copper face of substrate; Constitute a kind of resistance agent of covering property, for follow-up optionally etching or electroplating processes are prepared in advance.The mode of this transfer is commonly referred to as " screen painting " and claims " serigraphy " again.
Under the background of global warming, become global focus with low energy consumption, low pollute " low-carbon economy " that be the basis.Energy-saving and emission-reduction are imperative, and low carbon development has become the inexorable trend of social development gradually, and a kind of attitude, a kind of obligation, a kind of especially responsibility are not only in the low-carbon (LC) life.Being utilized in the process of pursuing low-carbon (LC) of solar energy occupies consequence, and solar cell is exactly the core representative that solar energy utilizes.
But traditional electrode of solar battery printing is to adopt common silk screen plate to print, and generally more than 70um, this has seriously limited the raising of solar cell conversion ratio in the line footpath of its thin grid line printing.
The utility model content
The technical problem that the utility model will solve provides a kind of electrode of solar battery mask to print version; This mask can print the thin grid line that the outlet footpath is little, depth-width ratio is big; Reduce the resistance of grid line, increased silicon plate light-receiving area, improved the electricity conversion of solar cell.
In order to solve the problems of the technologies described above, the technical scheme that the utility model is taked is following:
A kind of electrode of solar battery mask to print version is characterized in that, comprises sandwich construction, is made up of ground floor and second layer electroformed layer at least, and said electroformed layer is provided with main grid line and thin grid line.
The main grid line of ground floor electroformed layer is connected through bridging with thin grid line.
Main grid line bridging connection at the ground floor electroformed layer is provided with the array point that conductive silver paste can't see through on the net.
The graphics shape of said array point is circle, rhombus, rectangle, square, triangle or any limit number greater than 4 polygon.
The main grid line of second layer electroformed layer does not have bridging with thin grid line and is connected.
Mask also comprises the 3rd layer of electroformed layer, and the main grid line of the 3rd layer of electroformed layer does not have bridging with thin grid line and is connected.
Mask also comprises the 4th layer of electroformed layer, and the main grid line of the 4th layer of electroformed layer does not have bridging with thin grid line and is connected.
The width of described thin grid line is less than 70 microns.
Said mask is by being stainless steel mask, nickel metallic mask, nickel based metal mask or other metallic mask
Be provided with in described mask edge arrange according to certain rules lateral opening.
Described mask directly is fixed on the screen frame.
