Description
Technical field
The present invention relates to cell piece printing technology, specially a kind of cell piece secondary printing device.
Background technology
In current photovoltaic industry, due to silk-screen printing technique technology maturation, technique is simple and precision is easily controlled, quilt
The front electrode of solar cell is widely used to form, but in the case where pursuing the trend of solar cell of high-efficiency and low-cost at present, silk
Net printing technology gradually shows its limitation, and in solar cell manufacture process, the optimization of secondary grid line depth-width ratio is increasingly
Paid attention to extensively, the height of the secondary grid line of solar cell is higher, and the transmission resistance of secondary grid line will be lower；And the width of secondary grid line
It is wider, although can equally reduce resistance, effective area of shining light can be reduced, can be lost more than gain on the contrary；Conversely, refine secondary grid
Light-receiving area can then be increased, improve the conversion efficiency of solar cell；The secondary grid line of solar cell is done it is advantageous to being and
Thin and high, i.e., the depth-width ratio of secondary grid line is the higher the better.
Current traditional silk-screen printing, due to being restricted by slurry rheological property, the printing height lifting of secondary grid is often
Need the increase of dependence width；Further, since the limitation of the screen mesh printing plate thickness used, can also influence the print through screen mesh printing plate
The following ink of slurry, so there is also limitation, in addition in the grid line of solar cell, its secondary grid line for the height of the slurry of printing
Effect with main gate line is not fully consistent, and secondary grid line is mainly collected to caused photogenerated current in solar cell, main grid
Line is electrically connected with secondary grid line, and the electric current that secondary grid line is collected carries out collecting output, so secondary grid line needs and solar cell shape
Into Ohmic contact, and main gate line with solar cell without forming Ohmic contact.But it is in traditional silk-screen printing technique
Main gate line and secondary grid line are printed simultaneously using a kind of slurry, in order to improve the height of secondary grid line as far as possible, in the prior art generally
This purpose is realized using secondary printing.
But in secondary printing technology, main technology point is exactly to need to carry out the cell piece for carrying out secondary printing
Alignment, prevents that slurry can not be printed well during secondary printing, but current secondary printing alignment methods generally use
The directly hand-held cell piece of worker is aligned, and is not only wasted time and energy, and alignment result is also poor, is also easy to cause dirt to cell piece
Dye, it is very inconvenient.
