MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...

Passivating electron contact based on highly crystalline nanostructured silicon oxide layers for silicon solar cells

We present a novel passivating contact structure based on a nanostructured silicon-based layer. Traditional poly-Si junctions feature excellent junction characteristics but their optical absorption induces current losses when applied to the solar cell front side. Targeting enhanced transparency, the poly-Si layer is replaced with a mixed-phase silicon oxide/silicon layer. This mixed-phase layer...

Morphology and hydrogen in passivating amorphous silicon layers

Hydrogenated intrinsic amorphous silicon ((i) a-Si:H) can be grown by plasma-enhanced chemical vapor deposition with a non-columnar or columnar morphology. Nuclear resonant reaction analysis and corresponding effective stopping cross section analysis indicate a dependency of hydrogen effusion on the morphology of the (i) a-Si:H layer as well as the doping type and concentration of the c-Si wafe...

Crystal engineering of mixed-metal Ru-Ag coordination networks by using the trans-[RuCl2(pyz)4] (pyz = pyrazine) building block.

In the rational development of new strategies for the crystal engineering of coordination networks[1] and of metal-based supramolecular architectures[2] the use of predetermined building blocks has assumed an increasing relevance in recent times. For example, molecular corners containing transition metals with programmed coordination angles, such as cisprotected PdII and PtII square-planar comp...
