Varian Semiconductor Equipment Associates to Introduce the Solion(TM) Blue Implant Process at vTech Technical Seminar in Valenci

New information about how ion implant technology can improve solar
cell efficiency while reducing manufacturing costs will be
presented at Varian Semiconductor Equipment Associates' (NASDAQ:
VSEA) vTech technical seminar, held in conjunction with next week's
European Photovoltaic Solar Energy Conference and Exhibition (EU
PVSEC) in Valencia, Spain. Varian is inviting cell manufacturers
and technology partners to attend the vTech event, which is being
held at a venue near the Feria Valencia Exhibition Center on
Tuesday, Sept. 7.
The main focus of this vTech, the second of the summer, will be
to review cell efficiency and manufacturing data gathered by select
customers and partners utilizing Varian's Solion Blue process.
Solion Blue is designed to produce high efficiency P-type
mono-crystalline solar cells utilizing the proprietary patterned
implant technology of Varian's Solion ion implant platform. Solion
Blue fully exploits all the inherent advantages of ion implant
including high throughput, high precision and superior junction
formation.
The Solion Blue process reduces manufacturing costs and
increases cell efficiency by increasing the blue-light response of
the solar cell and eliminating the so called "dead zone" from the
cell surface. By using Varian's Precision Patterned Implant (PPI)
technology, contact regions on the cell surface can be doped to 50
ohms/sq while the field is doped more lightly at 80 ohms/sq. The
lighter-doped field region will have inherently better blue
response than cells utilizing blanket doping with phosphorous
oxychloride (POCl3). Typically, average conversion efficiencies of
a standard POCl3 process will increase to greater than 18.5% by
implementing Solion Blue. Current champion data has shown cell
efficiencies approaching 19%.
By eliminating the use of POCl3, Solion Blue users will achieve
a simplified process flow that is easy to integrate into existing
manufacturing lines. Edge-isolation process steps are eliminated,
and the phosphor-silicate glass surface passivation layer created
by the POCl3 process is replaced by a superior thermal oxide layer,
further increasing efficiency.
Jim Mullin, GM of Varian's Solar Products group said, "The vTech
at Valencia will be the first public presentation of Solion Blue
customer data. We are very excited to provide proof of how our
groundbreaking process technology increases cell efficiency and
decreases manufacturing costs." Added Mullin, "Customer response to
our Solion announcement at Intersolar earlier this year has been
tremendous. As a result, we are expanding our solar cell
manufacturing capability at our facility in Gloucester, Mass., to
keep up with demo demand."
