In industry only Cz-Si is used. Hydrogen bulk passivation and thermal load of the wafers are different in the buried contact process and can be key issues to reach high efficiencies with multi-crystalline silicon. Adjacent String Ribbon wafers are used to monitor the change of bulk lifetime during a buried contact process. Bulk lifetime was measured 2-dimensionally resolved with μ-PCD. An improvement of PECVD-SiN deposition without a firing step was measured. The heavy 10 Ohm/sq diffusion leads to a degradation due to effusion of hydrogen. Bulk lifetime after hydrogen passivation by MIRHP in a buried contact solar cell process is similar to an adjacent wafer after a screen print process, therefore higher efficiencies of buried contact cells are expected.</dcterms:abstract> <dc:contributor>Clark-Phelps, Bob</dc:contributor> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dc:contributor>Arumughan, Jayaprasad</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:rights rdf:resource="https://kops.uni-konstanz.de/page/termsofuse"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2018-04-30T14:56:14Z</dc:date> <dc:contributor>Hahn, Giso</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/42211"/> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/41"/> <dc:rights>terms-of-use</dc:rights> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2018-04-30T14:56:14Z</dcterms:available> <dc:contributor>Raabe, Bernd</dc:contributor> <dc:creator>Raabe, Bernd</dc:creator> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/42211/3/Raabe_2-1svegw0j9da9w4.pdf"/> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/42211/3/Raabe_2-1svegw0j9da9w4.pdf"/> <dcterms:title>Lifetime monitoring and hydrogen passivation in a buried contact cell process using String Ribbon silicon</dcterms:title> <dcterms:issued>2006</dcterms:issued> </rdf:Description> </rdf:RDF>
