Laser Welding Machine, PE-W700-A

Laser Edge Deletion
The PE-W700-A laser welding machine is used for electrical isolation and hermetic sealing of modules. It is also used for the complete removal of every layer from the edge of fully processes thin film solar cells on glass substrates when required. The laser edge deletion technology provides a better performance over traditional techniques, like sand blasting and grinding.

  • Laser Welding Machine, PE-W700-BLaser Dielectric Ablation is the application of advanced metallization schemes in order to reduce shadow losses and series resistance losses. It is also done to improve contact to the emitter.
  • Laser Welding Machine, PE-W700-EThis particular laser welding machine is used for Emitter Wrap Through (EWT) and Metallization Wrap Through (MWT) solar cells. For these solar cells, the emitter contacts are transferred to the rear of the wafer, and connected to the front emitter using metallized laser drilled holes.
