Heraeus Introduces SOL205B and Improvements in SOL9621 Series at SNEC 2015



-- Heraeus customization enhances performance of products for customers



SHANGHAI -- The Heraeus Photovoltaics Global Business Unit, a worldwide leading supplier of metallization pastes for the photovoltaic industry, will introduce two new product modifications for front-side and back-side applications at the SNEC (2015) International Photovoltaic Power Generation Conference & Exhibition from April 28(th)  through April 30(th) , 2015 in Hall: W3 Booth: 660. 



The Heraeus SOL205B is a back-side tabbing paste for mono- and multicrystalline silicon solar cells.  This newest formulation optimizes the Ag content and glass chemistry to provide higher and consistent adhesion before and after high temperature ageing.  The SOL205B provides cell manufacturers with enhanced busbar adhesion and therefore improved module reliability. At the same time, the SOL205B has a lower silver content and paste usage per cell giving it an excellent performance to cost ratio. 



Heraeus' SOL9621 Series includes the latest product customizations from Heraeus' successful SOL9621 Series launched at last year's SNEC tradeshow. According to Dr. Weiming Zhang, "For many customers, we have created several improvements in the SOL9621 Series relative to the products we released in this series last year.  Alpha testing customers with LDE applications achieved up to 0.1% absolute higher cell efficiency.  This is due to the reduced contact resistance and stable contact formation.  The lower recombination leads to higher V(oc).  The latest versions of the SOL9621 Series also has improved printability with the demonstrated ability of ultra-fine line printing, suitable for screen openings less than 40 micron.  This paste is ideal for LDE single printing, double printing and PERC applications."  Several versions of the Heraeus SOL9621 Series are currently in mass production and are available in large volumes.
