Contrary to screen-printing technology, with laser transfer printing the metallisation is carried out contact-free. The metalliferous pastes are printed in various patterns in-line and entirely in digital format. The LTP 1500 is suitable for coating both the front and rear sides of all solar cell types.

Contact-free system for the metallisation of solar cells

• Throughput of 1,650 wafers per hour
• High yield due to contact-free printing
• Fully digital printing of all patterns
• Trouble-free printing of smallest lines (min. 80 µm @ 600 dpi)
• Usage of standard metal pastes
• Wet in wet rear-side metallisation makes drying superfluous
• Suitable for thin wafers (min.110µm)
• Low running costs
