Heraeus to Showcase Metallization Pastes for Solar Cells at EU PVSEC2013

The Heraeus Photovoltaics Business Unit will be attending the exhibition of EU PVSEC 2013 in Paris, Parc des Expositions Paris Nord Villepinte, hall 2, booth 2/C3, from October 1-3, 2013. Heraeus will be highlighting several of their newest products in their current portfolio of metallization pastes that provide solar cells with higher efficiency at a reduced cost per Wp.

Lowering cost, especially silver cost in cell metallization will be a key topic at our booth. Heraeus pastes allow cell manufacturers to lower the silver cost for front-side metallization to below $0.01 per Wp (as demonstrated by the Institute for Solar Energy Research Hamelin, Germany; solar cell: PERC, printing technique: Dual Print; efficiency: 20.2%). Sure, low cost per Wp is a key objective for cell manufactures, with increasing importance. However, high cell efficiency has always been and continues to be the key driver in cell production.

During the show, Heraeus will be highlighting their SOL9610 Series of front-side metallization pastes, which continues successful market adaptation. Improvements to the SOL9610 Series provide 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.

New to their portfolio is the SOL9350 Series, designed for n-type cells with p+ wafer surfaces. This series of pastes provides improved printability and allows customers 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%.

A key characteristic of Heraeus pastes is their excellent adhesion to both the front-side and back-side of solar cells. "In the R&D process, we focus on formulating pastes that advance both the electrical and mechanical performance of solar cells. Adhesion is considered a key factor in the mechanical performance of cells. During our paste development process, we will not sacrifice the mechanical performance and reliability of cells," said Dr. Weiming Zhang, Vice President of Technology for the Heraeus Photovoltaic Business Unit.
