Ferro Electronic Materials is to launch two new print-on-print metallization pastes at the EU PVSEC conference and exhibition. The NS 33-514 and NS 33-515 pastes comprise optimized inorganic and organic properties, making them compatible with the double-printing/print-on-print) process.
The company’s NS 33-514 and NS 33-515 are capable of printing grid lines that are 70-microns wide with a greater than 0.3 aspect ratio. Double-printing of metal grid lines permits solar cell manufacturers to print taller, narrower lines, reducing the shadowing effect caused by wide grid lines, enhancing electrical conductivity.
“Ferro has been engaged with double printing applications for more than five years,” said Todd Williams, business manager for Ferro Electronic Materials. “This technology is experiencing strong pull due to the improvements in electrical efficiency possible from the higher aspect ratios that can be produced.”
Ferro Electronic Materials will be exhibiting on Level 3, Hall 4, Booth C11.
