Rectangular-shaped laser beam realizes a beautiful scribing line!
This system is used for processing thin-film photovoltaic cells. It removes all edge layers from a substrate (four side edges) to electrically isolate them from each other. Compared with sandblasting, this system is much more cost-effective because it (1) eliminates the need for a masking process; (2) eliminates the need for a cleaning process; (3) is unlikely to create micro-cracks; and (4) reduces expendable supplies.
These types of machines are being rapidly replaced by laser type ones throughout the world. We recommend that you consider using our laser thin-film edge deletion machines the next time you plan to improve the cost performance of your production lines. Our system's rectangular "top hat" beams provide clear and fast deletion with reduced overlap ratios.
We provide systems that are ideally suited to meeting your processing priorities, so it goes without saying that they offer a high throughput. We also provide systems for the edge isolation of silicon crystalline (bulk) type photovoltaic cells, such as single crystalline, polycrystalline, and tandem crystalline structures.
