The impact of bromine substitution on the photophysical properties of a homodinuclear Ru–tpphz–Ru complex

Ruthenium–polypyridine complexes play an important role as as photosensitizers in supramolecular photocatalysis. Using multiple Ru-centers within a single supramolecular catalyst might be a promising...

Photophysical Dynamics of a Ruthenium Polypyridine Dye Controlled by Solvent pH

The photophysics of the novel ruthenium dye [Ru(tmBiBzIm)(dppz)(tbbpy)]2+ (tmBiBzIm = 5,5′,6,6′-tetramethyl-2,2′-bibenzimidazole, dppz = dipyrido[3,2-a:2′,3,3′-c]phenazine, tbbpy = 4,4′-di-tert-butyl-2,2′-bipyridine)...

Silicon nanowire based heterojunction solar cells

Silicon nanowire solar cells with heterojunctions were prepared on single crystalline silicon wafers. The nanowire arrays were generated by silver catalyzed etching of n-type wafers. After careful removal...

Thin film solar cells based on diode Laser crystallized polycristalline silicon

Polycrystalline silicon thin film solar cell layer systems on glass were prepared in a two-step process based on first generating a seed layer by diode laser crystallization followed by epitaxial thickening....

Silicon nanowire solar cells with a-Si hetero-junction showing 7.3% efficiency

Core-shell silicon nanowire (SiNW) solar cells with an a-Si heterojunction were prepared on SiNW arrays, which were etched into n-type silicon wafers or into n-doped multicrystalline silicon thin films...

Raman Spectroscopy: Principles, Benefits & Applications

Printed conductive features for DNA chip applications prepared on PET without sintering

We present here an innovative and cheap alternative for the preparation of circuit boards conductive tracks printed on flexible polymer substrates at room temperature. For this purpose, we applied a combination...

Super-Resolution Wide Field Microscopy by Illumination with a Nano Hole Array

Kohärenz im Mikrometerbereich, Messung und Anwendung

LEDs, Halogenlampen und Quecksilberdampflampen wurden mit einem erweiterten Young-Interferometer vermessen. Mittels Nanohole Array wurden Vielfach-Interferenzen erzeugt und die räumliche Kohärenzlänge...
