Sawing wire for multi-wire sawing

Since the wafer is the most expensive portion of crystalline silicon-based solar cells, the production yield is critical to making solar energy competitive in the race for grid parity. To guarantee more output at a consistent quality, we focus on 2 domains: achieving the highest output while maintaining a high level of quality.

Using a lower wire diameter directly results in more wafers produced per kg polysilicon, as well as minimized material loss and a reduction of slurry consumption. Bekaert gives you the opportunity to try out new intermediate diameters close to your current diameter (115, 125μm). As such, you can benefit from an immediate and significant saving of production costs, without major changes in process settings (slurry, speed, etc…).

When you partner with Bekaert, you can rely on high-level sawing wire expertise and technical support, tailored to meet your needs and demands. We assign a dedicated team to work on your project from the beginning of the process to the roll-out. We want to support you with consistent quality performance on a global scale, improving yield and adding real value to your business. Rather than being just a supplier, we want to help you grow your business.
