Photovoltaics
The dynamic growth of the solar cell industry has created a demand for improved contact materials.
Five Star is dedicated to applying its extensive experience in the field of photovoltaic metallizations
to providing the next generation of materials for crystalline silicon cells.
The application of Five Star's patented cavitation technology results in ink formulations with dramatically
improved dispersion and particle size control. ElectroSperse S-series conductor pastes include screen-printable
silver inks for front surface contact to both conventional and high-resistance emitters. A new generation of front
contact inks with improved flow properties is under development for dispensing via non-contact printing methods.
ElectroSperse S-series products are designed for compatibility with high throughput rapid thermal
processing. These inks deliver high fill factors and cell efficiencies on both single and multicrystalline
silicon substrates. Our unique dispersion capability and formulation know-how also enables printing of
unique front side contact geometries, enabling higher performance through design advancements.
Five Star also offers dispersion services for preparation of silicon nitride slips used in the processing
of silicon wafers. Please contact your Five Star representative for more information on this service.
