Ito Giken's polyamideimide-based printing paste serves as an insulating layer between the electrodes in back-contact solar cells. Compared to traditional solar back films, this material offers a more effective and reliable insulation solution. The paste is in liquid form, allowing it to be applied onto the electromagnetic film through screen printing. As it dries, the slurry naturally flows and fills the conductive areas of the cell before solidifying, ensuring even coverage and optimal performance. The addition of a soluble resin filler enhances both the mechanical strength and electrical insulation properties while maintaining excellent printability.
Product Design Concept
Key Advantages
- Polyamide imides provide exceptional heat resistance, making them ideal for use in high-temperature back-contact solar cell manufacturing processes.
- The inclusion of a soluble resin filler ensures a uniform coating with outstanding mechanical strength and insulation properties.
- Screen printing technology allows for cost-effective production, making this solution scalable and efficient for industrial applications.
