Solar battery is to efficiently use one of the important means of solar energy at present, and solar battery is imitated using photovoltaic
Answer principle that solar radiant energy is converted into electric energy, promoting the transfer efficiency of solar battery and reducing production cost is that industry is continuous
The target of pursuit.
In solar battery manufacturing process, influence of the printing of electrode to solar battery efficiency is very big.Electrode print is
Using screen printing technique, conductive silver paste is scraped back and forth on solar energy printing screen plate with scraper, silver paste passes through on printing screen plate
Thin grid, leak on cell silicon chip, then by drying and sintering form electrode.Electrode collects what inside solar energy battery generated
Electric current, and drawn and connect with external circuit.If the electrode width printed is uneven, or even disconnects, then battery produces
Passability of the raw electric current at the relatively narrow place of electrode is poor, or even can not pass through, and will reduce the transfer efficiency of solar battery.Cause
This, need to guarantee that the electrode width printed out is uniform, this will promote the production technique of thin grid on solar energy printing screen plate.
A key of thin grid production is exactly on halftone, it is to be ensured that the center line of thin grid is by printing screen plate opening portion
Heart position.Printing screen plate is that wire mesh is tightened in the metal outer frame of aluminum using screen-tensioning machine, and wire mesh is with stainless
Steel wire intersection is worked out, and rectangular mesh is formd between steel wire, also calls off oral area.Each opening portion area very little, it
Be arranged together, form a very intensive array.By tightening, the relative position of opening portion just has occurred wire mesh
Variation, then thin grid are possible to touch stainless steel wire, or thin grid have passed through not in the opening portion of same a line (or same row),
The electrode width printed in this way is uneven or disconnects.Therefore need accurately to measure the center of each opening portion, so
These centers are utilized afterwards, draw grating figure, ensure that the center lines of thin grid is (or same by the same a line of printing screen plate in this way
Column) opening portion center.The existing entire galley method of scanning is the center line for measuring thin grid line by line, has measured one piece of net in this way
Version needs a few hours, and efficiency is very low, and the consumption of operator's energy is excessive, and measurement is easy to appear wire jumper, and rejection rate when printing is caused to increase
Add.
