Heraeus launches metallization pastes for efficiency solar cells: Heraeus’ photovoltaics business unit exhibit...

Heraeus pastes make it possible for cell manufacturers to lower the silver cost for front-side metallization to below US$0.01 per Wp. One new product on show was the SOL9350 Series, designed for n-type cells with p(+) wafer surfaces. This series of pastes provides improved printability and makes it possible to achieve higher cells efficiencies. On bifacial n-type cells, the SOL9350 Series for p(+) wafer surfaces can be complemented with other Heraeus pastes, such as the SOL9610 Series or the lower silver SOL9300 Series. For back-side metallization, Heraeus offers low silver tabbing pastes with silver contents below 45%. Heraeus also exhibited irs SOL9610 Series of front-side metallization pastes, which now have finer line resolution and improved contact to silicon wafers. The series of pastes has demonstrated cell efficiencies greater than 19.5% on standard p-type cells. H...
