SPI Lasers presenterar mycket lovande resultat vid skärning av polykristallint kisel för användning i solceller
2007-09-25 16:58

Dr. Tony Hoult vid SPI Lasers testanläggning har med hjälp av
en 1070 nm fiberlaser på 200W lyckats åstadkomma skärytor
som tidigare inte varit möjliga vid skärning med lasrar vid dessa

SPI Lasers Application lab, San Jose, California, today
announced that work conducted by Dr. Tony Hoult at the US
applications facility of SPI Lasers shows promising results in
processing 0.2-0.8mm thick polycrystalline silicon as used in
solar cell production. Using a 200W CW-M 1070nm fibre laser
with a novel cutting technique, cutting speeds of up to 6m/min
on 200μm silicon ribbon have been readily achieved.

Analysis of the cuts show very smooth surfaces with minimal
debris or spatter, 40μm kerf with no appreciable taper. All this
indicates a promising and somewhat surprising new application
for these fundamental wavelength fibre lasers.

SPI has joined with the Cambridge Institute of Manufacturing in
the UK, recent purchasers of 200W SPI Fibre Lasers, and other
laser based research institutes around the world with similar
equipment, to conduct more detailed tests further trials.
Dr Bill O’Neill, of the CIM said: “The current laser cutting process
requires expensive DPSS lasers which require higher levels of
maintenance and are considerably slower. The early promise
shown by the SPI Laser trials will prove of real benefit to a
rapidly growing sector which aims to reduce cost, increase
throughput and improve product energy conversion efficiency”.
Said Jack Gabzdyl, Business Development Manager of SPI
Lasers, “In addition to the silicon cutting, SPI Lasers see a
number of new exciting opportunities within the solar industry for
fibre lasers including; thin film removal, edge deletion and
silicon scribing and are looking forward to delivering these to the

SPI are now talking with companies to conduct field trials. The
company would like to extend this invitation to device and
component manufacturers, academic intuitions and system
integrators from all four corners of the globe to work with SPI on
their own application specific trials. The fast track way to conduct
application trials is to take advantage of SPI’s free of charge, no
obligation proof of concept and try before you buy programs.
SPI provides a progressive program to support academic & not
for profit research centres.

Both the proof of concept and try before you buy programs
