Long-term stable front-side metallization based on environmentally friendly electroplated layers (LasVeGaS) - Subproject: Research into a long-term reliable and lead-free contacting technique for electrodeposited solar cells
|German title:||Langzeitstabile Vorderseiten-Metallisierung auf Basis umweltfreundlicher Galvanischer Schichten (LasVeGaS) - Teilvorhaben: Erforschung einer langzeitzuverlässigen und bleifreien Kontaktierungstechnik für galvanisch abgeschiedene Solarzelle|
|Duration:||1st May 2011 - 14th July 2014|
|Description:||In the sub-project of the CiS Research Institute for Microsensors and Photovoltaics, an innovative and lead-free contacting concept for high-performance solar cells with copper as the metallic conductor is to be developed. The technological challenge is the development of a long-term stable contact system with simultaneous industrial suitability.
The replacement of currently used silver- and lead-containing pastes or pure silver metal by copper makes it possible to intervene in the value chain for solar cells, since the raw material copper is more than 100 times cheaper than the raw material silver and is also available in practically unlimited quantities. However, the interconnection technology must be adapted to this type of metallization.
The focus of the sub-project is therefore on raising a laboratory-based lead-free soldering technique for solar cells to a level suitable for production. Such solder joints between lead-free solders and the novel cell metallization have not yet been sufficiently analyzed for stability, but have been the subject of current research on solar energy utilization for some time. The ultimate objective is to ensure the quality and service life of such novel contact systems for solar cells.
