The influence of the thickness of an additional dry thermal silicon dioxide (SiO2) to passivate the surface of the B-BSF is also investigated. The passivation quality is compared in two experiments: First Si lifetime samples with boron (B) emitter are passivated and their emitter saturation current densities (J0E) are determined with quasi-steady-state photoconductance (QSSPC) measurements after every process step. Secondly large area bifacial solar cells with different base doping are processed. The cell parameters are determined by illuminated current-voltage (IV) characteristics and the effective minority charge carrier diffusion lengths (Leff) are calculated with a model [1] using the internal quantum efficiencies (IQE) from spectral response measurements. The optimum B-BSF sheet resistance for the bifacial cell concept used is found to be 60 Ohm/sq. The optimum value of the thickness of the SiO2 layer for additional surface passivation is found to be in the range of 19- 30 nm dependent on the base doping.</dcterms:abstract> <dcterms:bibliographicCitation>First publ. in: Proceedings of the 24th European Photovoltaic Solar Energy Conference, September 2009, Hamburg.
