By drive-in of B and a subsequent POCl3 co-diffusion, p+ emitter and n+ front surface field (FSF) are established in a single process step. APCVD-SiOx is used to prevent the p+ emitter from being compensated during P diffusion. Its thickness needs to be adapted in order not to affect the p+ profile during POCl3 diffusion while keeping it removable. For rear junction solar cells, it is crucial to ensure low recombination activity at the front. Therefore, a selectively etched-back FSF is to be established in the solar cell. An adjusted etch-back solution increases n+ Rsheet successively and well controllably, accompanied by a drastic j0FSF reduction while simultaneously almost completely maintaining p+ Rsheet. A 43 /sq APCVD-AlOx passivated p+ emitter achieves j0E of only 52 fA/cm2. Total implied VOC of a pseudo solar cell structure attains up to 695 mV. The newly developed APCVD p+ emitter combined with the co-diffused and selectively etched-back FSF employed in an industrial n-type solar cell achieves 18.8% efficiency in a first experiment being still limited by a poor Ag/Al contact to the B-emitter.</dcterms:abstract> <dc:contributor>Book, Felix</dc:contributor> <dc:creator>Hahn, Giso</dc:creator> <dc:language>eng</dc:language> <dcterms:rights rdf:resource="http://nbn-resolving.de/urn:nbn:de:bsz:352-20150914100631302-4485392-8"/> <dc:creator>Demberger, Carsten</dc:creator> <dc:creator>Jiang, Kaiyun</dc:creator> </rdf:Description> </rdf:RDF>
