An optimized solar cell design which uses the same equipment as state of the art solar cells could be easily implemented into solar industry. In this paper an approach for a front side design is discussed, using more busbars than the widely used three busbar design for the solar cell front electrode. A simulation program based on the two-diode model was used summing up the series resistances of each contributor in a module optimizing the number and geometry of wires needed. The simulations reveal that the advantages of the multi busbar design originate from a reduction of effective finger length, opening up new possibilities for the cell design. It is demonstrated that the multi busbar solar cell design can increase the module efficiency by 0.5%abs and a reduction in the consumption of silver of over 89% can be achieved by using seed and plate techniques. A significant surplus in short circuit current can be realized by using round wires.</dcterms:abstract> <dcterms:title>Solar cell improvement by using a multi busbar design as front electrode</dcterms:title> <dspace:isPartOfCollection rdf:resource=""/> <dc:creator>Micard, Gabriel</dc:creator> <dc:creator>Braun, Stefan</dc:creator> <dc:contributor>Braun, Stefan</dc:contributor> <dcterms:rights rdf:resource=""/> <dc:language>eng</dc:language> <dcterms:available rdf:datatype="">2013-05-04T09:58:38Z</dcterms:available> <dc:creator>Hahn, Giso</dc:creator> <dc:contributor>Micard, Gabriel</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> </rdf:Description> </rdf:RDF>
