    <title language="eng">p-Type a-Si:H/ZnO:Al and μc-Si:H/ZnO:Al Thin-Film Solar Cell Structures—A Comparative Hard X-Ray Photoelectron Spectroscopy Study</title>
    <abstract language="eng">The chemical and electronic properties of a-&#13;
Si:H(B)/ZnO:Al and μc-Si:H(B)/ZnO:Al thin-film solar cell structures&#13;
are studied by hard X-ray photoelectron spectroscopy (HAXPES).&#13;
Using a combination of different X-ray excitation energies&#13;
and deliberate sample design, we were able to select the probed&#13;
volume, i.e., the silicon capping layer only or the silicon and zinc&#13;
oxide layer (including the buried interface). For the a-Si:H(B) material,&#13;
we find a higher deposition rate and a smaller value for the&#13;
modified Auger parameter than for μc-Si:H(B). In addition, we&#13;
find indications of a pronounced band bending limited to the very&#13;
surface of the a-Si:H(B) and the μc-Si:H(B) layers, which is more&#13;
distinct in the latter case.</abstract>

    <title language="eng">The silicon/zinc oxide interface in amorphous silicon-based thin-film solar cells: Understanding an empirically optimized contact</title>
    <abstract language="eng">The electronic structure of the interface between the boron-doped oxygenated amorphous silicon “window layer” (a-SiOx:H(B)) and aluminum-doped zinc oxide (ZnO:Al) was investigated using hard x-ray photoelectron spectroscopy and compared to that of the boron-doped microcrystalline silicon (μc-Si:H(B))/ZnO:Al interface. The corresponding valence band offsets have been determined to be (−2.87 ± 0.27) eV and (−3.37 ± 0.27) eV, respectively. A lower tunnel junction barrier height at the μc-Si:H(B)/ZnO:Al interface compared to that at the a-SiOx:H(B)/ZnO:Al interface is found and linked to the higher device performances in cells where a μc-Si:H(B) buffer between the a-Si:H p-i-n absorber stack and the ZnO:Al contact is employed.</abstract>
