Heraeus’ PV unit announced that during Intersolar North America 2012, July 10-12 at San Francisco’s Moscone Centre, it will be featuring its latest pastes for conventional and advanced cell designs. One of its highlighted products will be its SOL315, a low activity, low silver content paste for new passivation layer cell designs.
The company notes that SOL315 can be used for front-side and backside applications since when the paste is screen printed and fired onto passivated silicon wafers, it does not penetrate the passivation layer. Heraeus advised that SOL315 allows a significant drop of charge carrier recombination on passivated cSi wafer surfaces and can be used as a floating busbar on the front-side of cSI cells.
Andy London, global manager of the Heraeus photovoltaics business unit, commented, “We are looking forward to discussing the Heraeus SOL315 with our existing and prospective customers during the exhibition. This product helps to significantly improve output and efficiency by reducing the combination of charge carriers.”
Heraeus will have its products on display in the North hall, booth 5747.
