Thin-Film PV Scribing Using A High-Energy Picosecond Pulsed Fiber Laser

By Fianium

Thin-film photovoltaic (PV) fabrication is an extremely demanding industrial process. For these devices to be costcompetitive, high-throughput and quality must be coupled with low startup and maintenance costs. Maintenance-free high-energy picosecond fiber lasers offer a means to produce very high quality P1, P2, and P3 scribes of thin-film PV devices at rates exceeding 5000mm/s.

The Fianium HE1060/532 provides up to 10µJ pulses with peak powers up to 1MW and 10W average power, which makes it a cost-effective tool for high-throughput thin-film PV processing. The HE1060/532 provides the capability of inexpensive, maintenance-free, virtually defect-free scribing of thin-film solar cells at rates exceeding 5000mm/s. The unmatched quality and speed of P1, P2, and P3 scribes of thin-film PVs using a Fianium high-energy picosecond laser makes it the ideal tool for the process.
