Using light-induced plating technology very fine-structured and low-shadowing contact grids can be produced on the solar cell. In the first step the front contact fingers, so-called seed layers, are applied, for example using inkjet printing technology. In the second step, the contact lines are silver-plated to improve their electrical conductivity. The illuminated solar cell supplies the required polarity of the cell front side.

Inline module for the metallisation of solar cells on the emitter side

• Can be used for the deposition of different metals
• Increased cell efficiency due to higher conductivity
• Less grid shadowing due to thinner contact lines
• Stable and uniform local voltage distribution within the solar cell
• High output rate due to contact-free metallisation and smooth transport
• High process stability guarantees high reproduction accuracy
• Process control achieved by comprehensive process monitoring and visualisation
• Stable processing due to continuous replenishment of the process fluids
