Description
Technical field
The present invention relates to a kind of alloy and preparation method thereof, more particularly to a kind of for solar cell silk screen printing
Alloy and preparation method thereof.
Background technology
The preparation technology of solar cell is：Preceding cleaning-making herbs into wool-diffusion-plasma etching-rear cleaning-plasma
Vapour deposition-silk-screen printing-sintering-detection.
Wherein silk-screen printing and sintering process be：The solar cell that antireflective coating will be made carries out electrode preparation, battery
Electrode is prepared and uses silk-screen printing, and silver paste or silver-colored aluminium paste back electrode are first printed at the back side of battery, is printed aluminium paste after drying and is carried on the back
Electric field, is dried again, and then the electrode before the front printing silver paste of battery, is finally sintered, and sintering temperature is controlled in 800-
880 DEG C or so.
Current screen printing technique is highly developed, and in order to be able to produce cell piece in hgher efficiency, various slurries are also continuous
Update.The problem of unique puzzlement silk-screen printing be exactly in printing process scraper press to the fragment that is produced when half tone and silicon chip and hidden split
Piece problem.
The mesa material that we are directed to after the main cause of generation fragment rate is analyzed to silk-screen printing board changes
Make.
Either print front electrode or backplate electric field, its equipment print structure typically all use board, scraper,
The compositions such as half tone (centre is screen cloth), the table top with conveyer belt.Printing every time, table top and silicon chip will bear board and scraper to
The pressure for giving.Silicon chip is frangible, very thin, and develops to more thinning, and this just proposes requirement higher to the table top of board.Printing frequency
Rate be 30-50 pieces/min, silicon wafer thickness be 180-220 microns, mesa material must in continual production operation in 24 hours,
Ensure the high finished product rate of silicon chip.
Once there is producer using plastic materials such as PVC as table top, but due to table top insufficient strength, often deformation, instead
And increased fragment rate；Used mostly by the ferroalloy of cure process in production at present, but this table top at present, often
100-300 pieces just occur fragment or hidden sliver, and after using 2-4 month, mesa surfaces will become crude.Silicon chip is hidden
After splitting, by more than 800 DEG C of sintering link, easily crushed after being cooled back to room temperature.And have the hidden silicon chip for splitting, even if burning
Knot link is unbroken, in follow-up photovoltaic component encapsulating link, can also rupture.
