example 2
[0036] Example 2, embodiment figure, see figure 1 and Figure 7 Same as above, m=4, n=2, produce amorphous silicon thin-film solar panels with unit cell spacing of 10mm and external dimensions of 1000mm×2000mm×3.0mm.
[0037] Front electrode graphic production: place the composite transparent conductive film glass film with a size of 1000mm×2000mm×3.0mm facing up, place it on the X-Y axis loading work platform, start the large-format infrared laser marking system, and import the front electrode of the battery. engrave graphics, and set the marking range of the laser galvanometer scanning system to 500mm×500mm, divide the 1000mm×2000mm×3.0mm substrate to be marked into 8 marking areas of 500mm×500mm, and adopt multi-format marking In the way of engraving, 100 insulating isolation lines parallel to the long side with a spacing of 10mm are marked on the continuous conductive film of the substrate, see Figure 7 The part shown in 1'. In this way, the continuous conductive film ...
