Manufacturing advanced solar cell concepts like MWT or EWT cells need
innovative laser concepts. The easy automation of laser processing and
low manufacturing costs of laser tools are key functions for a sunny
future of the solar cell industry.
ROFIN introduces the new fiber laser PowerLine F30 Long Pulse system
which is combining high drilling performance on silicon solar cells
with the lowest cost of ownership. By using optimal pulse length, high
pulse energy and high TEMoo average power, the ROFIN PowerLine F30 LP
realizes processing speeds of less than 1 wafer/sec for trepanning
drilling on MWT cells.
Typically MWT solar cells also require cell edge respectively via
isolation. Another fiber based product, the Power Line F50 achieves
best isolation values at the highest processing speeds with up to 1
m/s. This 50 Watt unit with pulse frequency up to 200 kHz extends the
successful PowerLine F product family.
