Throughout the annealing, we monitor the evolution of the structural and electronic properties. The analysis of the bonds by means of the electron localization function reveals that dangling bonds move toward the free a-Si:H surface, leaving the interface region itself completely defect free. The hydrogen follows this movement, which indicates that in the case under consideration, hydrogen passivation does not play a significant role at the interface. A configuration with a satisfactory low density of defect states is reached after annealing at 700 K. A detailed characterization of the electronic states in this configuration in terms of their energy, localization, and location reveals that, although no dangling bond states can be found near the interface, localized interface states do exist and are attributed to a potential barrier at the interface. The quantitative description of electronic localization also allows for the determination of the a-Si:H mobility gap, which, together with the c-Si band gap, yields band offsets that are in qualitative agreement with experimental observations. 000851557 536__ $$0G:(DE-HGF)POF3-121$$a121 - Solar cells of the next generation (POF3-121)$$cPOF3-121$$fPOF III$$x0 000851557 536__ $$0G:(DE-Juel1)jiek50_20141101$$aAb-initio description of transport and recombination at defective interfaces in solar cells (jiek50_20141101)$$cjiek50_20141101$$fAb-initio description of transport and recombination at defective interfaces in solar cells$$x1 000851557 588__ $$aDataset connected to CrossRef 000851557 7001_ $$0P:(DE-HGF)0$$aGiusepponi, Simone$$b1 000851557 7001_ $$0P:(DE-HGF)0$$aGusso, Michele$$b2 000851557 7001_ $$0P:(DE-HGF)0$$aCelino, Massimo$$b3 000851557 7001_ $$0P:(DE-Juel1)130210$$aAeberhard, Urs$$b4$$eCorresponding author 000851557 773__ $$0PERI:(DE-600)2065612-9$$a10.1007/s10825-018-1238-1$$n4$$p1457–1469$$tJournal of computational electronics$$v17$$x1572-8137$$y2018 000851557 8564_ $$uhttps://juser.fz-juelich.de/record/851557/files/Czaja2018_Article_ComputationalCharacterizationO-1.pdf$$yRestricted 000851557 8564_ $$uhttps://juser.fz-juelich.de/record/851557/files/Czaja2018_Article_ComputationalCharacterizationO-1.pdf?subformat=pdfa$$xpdfa$$yRestricted 000851557 909CO $$ooai:juser.fz-juelich.de:851557$$pVDB 000851557 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)136941$$aForschungszentrum Jülich$$b0$$kFZJ 000851557 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130210$$aForschungszentrum Jülich$$b4$$kFZJ 000851557 9131_ $$0G:(DE-HGF)POF3-121$$1G:(DE-HGF)POF3-120$$2G:(DE-HGF)POF3-100$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bEnergie$$lErneuerbare Energien$$vSolar cells of the next generation$$x0 000851557 9141_ $$y2018 000851557 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000851557 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR$$bJ COMPUT ELECTRON : 2015 000851557 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000851557 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000851557 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000851557 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000851557 915__ $$0StatID:(DE-HGF)1160$$2StatID$$aDBCoverage$$bCurrent Contents - Engineering, Computing and Technology 000851557 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000851557 9201_ $$0I:(DE-Juel1)IEK-5-20101013$$kIEK-5$$lPhotovoltaik$$x0 000851557 9201_ $$0I:(DE-82)080012_20140620$$kJARA-HPC$$lJARA - HPC$$x1 000851557 980__ $$ajournal 000851557 980__ $$aVDB 000851557 980__ $$aI:(DE-Juel1)IEK-5-20101013 000851557 980__ $$aI:(DE-82)080012_20140620 000851557 980__ $$aUNRESTRICTED 000851557 981__ $$aI:(DE-Juel1)IMD-3-20101013
