The method of printing a crystalline silicon solar cell electrodes

The present invention relates to a method for printing a crystalline silicon solar cell electrode, the specific steps: 1) preparing the silicon electrode prepared, made in accordance with the first electrode-printed pattern or design by screen printing, and then drying or sintering; 2) again for a second gate electrode lines printed according to the metal thin printed pattern or printed pattern on the first silicon wafer, and then drying or sintering. Using the principles of the invention by screen printing, the motor and fine metal gate line printing step, so that the thickness of the halftone pattern consistent thickness, the screen under pressure, change uniformly shaped, to avoid the partial print is too thick, the pulp is reduced portion material spill, a reduction of the consumption of the slurry, and reduces the screen uneven stress broken version.
