In solar cell production, the metallization process follows the anti-reflective coating step. Using the screen-printing process, a fine metal grid and busbars are printed onto the cell. This is followed by isolation of the edges, after which the solar cells are sorted.

Our qualified and capable GP Solar cell technology team provides technical support for Analog™ metallization paste made by our partner Monocrystal. We are responsible at companies around the world for integrating pastes into processes and for process optimization.

We perform these services for Ag and Al/Ag metallization pastes for

• n-type bifacial silicon cells
• p-type bifacial silicon cells
• p-type silicon cells with both-side dielectric passivation

• Maximum efficiency and minimum bow even on thin Si solar cells (160 µm), very good adhesive performance
• Sophisticated quality control of paste products
• High availability of paste products
• Environmentally friendly products free of lead and cadmium
• Short feedback cycles in research and development
