Optomec announced today
that leading photovoltaic material suppliers are now providing material for
the company's Aerosol Jet® printing process. Established material vendors
Cabot Corporation, DuPont® Microcircuit Materials and Heraeus, along with
market newcomer Five Star Technologies™, have worked closely with Optomec
over the past year to optimize their front-side metallization materials for
the Aerosol Jet process. With the availability of source materials from these
companies, Optomec and its partners are now fully prepared to meet mutual customers'
increased cell efficiency requirements.
Initial material availability will be for seed and plate applications for crystalline
wafers. The Aerosol Jet print system is capable of printing front-side collector
lines with a width of 40 microns or less at production speeds of up to 2400
wafers per hour. The print material has been optimized for etching through the
Silicon Nitride layer and meets series resistance requirements. The printing
step is followed by a plating process to build up the conductivity of the collector
lines. Optomec is working in close conjunction with its material partners with
goals of further enhancing the seed and plate process along with delivering
a fully printed front-side metallization solution that includes a multi-material
capability, to allow contact resistance and conductivity to be optimized separately.

Dave Ramahi, President and CEO of Optomec, states, “We are pleased that
leading and emerging material suppliers have partnered with Optomec to fully
enable the benefits of the Aerosol Jet process for solar cell applications.
This will allow our customers to readily implement the Aerosol Jet solution
for printing front-side collector lines and to meet emerging backside metallization
