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 electricity for this purpose.

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
