In this study, the influence of carbon incorporation in the concentration range of 6.9-21.5 at% on boron-doped polycrystalline silicon carbide (poly-SiCx) layer properties is investigated and interpreted in the context of an application as full-area passivating contact on the front side of a solar cell. For constant annealing parameters, higher carbon concentrations reduce the crystallinity of the layers. A high crystallinity in turn is confirmed to be a key parameter for the application in a solar cell as it ensures both low resistivity as well as low parasitic absorption. Low recombination current densities in the range of 7.2-12.2 fA/cm 2 are determined for all layers on interfacial oxides on planar surfaces, whereas the differences are rather related to variations in the boron concentration than to the carbon concentration or the deposition parameters. A reduction of the (p) poly-SiCx layer thickness down to 10 nm would yield a parasitic absorption current density of 1.13 ± 0.13 mA/cm 2 . Using this value and the lowest measured recombination current density, a simple model predicts a theoretical solar cell efficiency limit of 26.7 ± 0.2%. 000888966 536__ $$0G:(DE-HGF)POF3-113$$a113 - Methods and Concepts for Material Development (POF3-113)$$cPOF3-113$$fPOF III$$x0 000888966 588__ $$aDataset connected to CrossRef 000888966 7001_ $$0P:(DE-HGF)0$$aWeit, Swetlana$$b1 000888966 7001_ $$0P:(DE-HGF)0$$aRinder, Johannes$$b2 000888966 7001_ $$00000-0002-2367-9955$$aGlatthaar, Raphael$$b3 000888966 7001_ $$0P:(DE-Juel1)139534$$aMoller, Soren$$b4$$eCorresponding author 000888966 7001_ $$0P:(DE-HGF)0$$aHahn, Giso$$b5 000888966 7001_ $$0P:(DE-HGF)0$$aTerheiden, Barbara$$b6 000888966 773__ $$0PERI:(DE-600)2585714-9$$a10.1109/JPHOTOV.2020.3023506$$gVol. 10, no. 6, p. 1624 - 1631$$n6$$p1624 - 1631$$tIEEE journal of photovoltaics$$v10$$x2156-3403$$y2020 000888966 8564_ $$uhttps://juser.fz-juelich.de/record/888966/files/09205910.pdf$$yRestricted 000888966 909CO $$ooai:juser.fz-juelich.de:888966$$pVDB 000888966 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)139534$$aForschungszentrum Jülich$$b4$$kFZJ 000888966 9131_ $$0G:(DE-HGF)POF3-113$$1G:(DE-HGF)POF3-110$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lEnergieeffizienz, Materialien und Ressourcen$$vMethods and Concepts for Material Development$$x0 000888966 9141_ $$y2020 000888966 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bClarivate Analytics Master Journal List$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)0160$$2StatID$$aDBCoverage$$bEssential Science Indicators$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)0113$$2StatID$$aWoS$$bScience Citation Index Expanded$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bIEEE J PHOTOVOLT : 2018$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS$$d2020-09-09 000888966 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5$$d2020-09-09 000888966 920__ $$lyes 000888966 9201_ $$0I:(DE-Juel1)IEK-4-20101013$$kIEK-4$$lPlasmaphysik$$x0 000888966 980__ $$ajournal 000888966 980__ $$aVDB 000888966 980__ $$aI:(DE-Juel1)IEK-4-20101013 000888966 980__ $$aUNRESTRICTED 000888966 981__ $$aI:(DE-Juel1)IFN-1-20101013
