      abstract     = {A study on the microstructure of intrinsic,
                      microcrystalline silicon (mu c-Si:H) layers deposited with
                      various silane concentrations is presented. The layers were
                      fabricated in a large-area Plasma-Enhanced Chemical Vapor
                      Deposition (PECVD) system on rough TCO-coated substrates.
                      The microstructure was investigated by Raman spectroscopy
                      and X-ray diffraction (XRD) in two different geometries. The
                      structural properties are related to the performance of
                      solar cells deposited together with the mu c-Si:H layers.
                      The crystalline volume fraction of the studied films ranged
                      from highly crystalline to amorphous as derived from Raman
                      spectroscopy and Grazing Incidence XRD. A hexagonal silicon
                      phase, which is related to stacking faults and twins
                      appeared in Bragg--Brentano and Grazing Incidence
                      diffractograms, and revealed that these types of defects
                      occur more pronounced on crystal planes that grow parallel
                      to the sample surface. By evaluating the integrated
                      intensity ratio of the {220} to {111} reflection of cubic
                      silicon a small preferential orientation (texture) was
                      observed for the high-crystalline material. Material close
                      to the transition to amorphous phase (that leads to an
                      optimum in solar cell performance) exhibits no preferential
                      orientation. This shows that for the material under
                      investigation - which is optimized for tandem solar cell
                      with efficiencies above $12\%$ - a preferential orientation
                      is not a requirement to achieve device-quality material for
                      good solar cell performance. (C) 2011 Elsevier By. All
