In this framework, μc-Si:H i-layers grown at low silane dilution ([SiH4]/[SiH4+H2]) were deposited on oxidized silicon wafers at different temperatures and dilutions and current voltage characteristics were measured in a 2 point configuration at various temperatures. At low voltage we extracted the activation energy and the conductivity at room and infinite temperature. At high voltage the conduction is due to Space Charge Limited Currents (SCLC) and excess carriers will fill the conduction bandtail traps and their distribution can then be determined around the Fermi level. The discovery of a Meyer-Neldel rule in these μc-Si:H layers seems to be consistent with a conduction mechanism involving the amorphous tissue. The study of SCLC is consistent with a widely distributed exponential conduction bandtail in correlation with the conduction in the amorphous tissue and low photogain performances.</dcterms:abstract> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:creator>Peter, Kristian</dc:creator> <dc:creator>Isella, G.</dc:creator> <dc:creator>Micard, Gabriel</dc:creator> <dc:contributor>Micard, Gabriel</dc:contributor> <dc:rights>deposit-license</dc:rights> <dc:contributor>Isella, G.</dc:contributor> <dc:contributor>Peter, Kristian</dc:contributor> <dc:language>eng</dc:language> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/932"/> <dcterms:bibliographicCitation>The compiled state-of-the-art of PV solar technology and deployment : 22nd European Photovoltaic Solar Energy Conference, EU PVSEC ; proceedings of the international conference, held in Milan, Italy, 3 - 7 September 2007. - Munich : WIP-Renewable Energies, 2007, pp. 2169-2172</dcterms:bibliographicCitation> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-22T17:52:20Z</dc:date> </rdf:Description> </rdf:RDF>
