Resonances and absorption enhancement in thin film silicon solar cells with periodic interface texture

Christophe Ballif, Franz-Josef Haug, Karin Söderström, Ali Naqavi

We study absorption enhancement by light scattering at periodically textured interfaces in thin film silicon solar cells. We show that the periodicity establishes resonant coupling to propagating waveguide modes. Ideally, such modes propagate in the high i ...

Ruthenium Sensitizer with Thienothiophene-Linked Carbazole Antennas in Conjunction with Liquid Electrolytes for Dye-Sensitized Solar Cells

Michael Graetzel, Shaik Mohammed Zakeeruddin, Nuttapol Pootrakulchote

A new heteroleptic ruthenium complex, coded CYC-B12, incorporating an antenna ligand composed of sequential connections of a thienothiophene conjugated bridge and carbazole hole-transport moiety was prepared. This new sensitizer exhibits a lower energy MLC ...

Absorption spectroscopy of adenine, 9-methyladenine, and 2-aminopurine in helium nanodroplets

Marcel Drabbels

High-resolution absorption spectra of adenine, 9-methyladenine and 2-aminopurine in helium nanodroplets have been recorded. In contrast to molecular beam experiments, large variations in linewidths are observed for adenine and 9-methyladenine. At the same ...

High-resolution excitation and absorption spectroscopy of gas-phase p-coumaric acid: unveiling an elusive chromophore

Marcel Drabbels

We report on the first successful high-resolution spectroscopic studies on isolated para-coumaric acid, the chromophore of the photoactive yellow protein which has become a model system for studying biological light induced signal transduction. Employing v ...

Impact of secondary gas-phase reactions on microcrystalline silicon solar cells deposited at high rate

Christophe Ballif, Grégory Bugnon, Andrea Feltrin, Thomas Söderström, Benjamin Strahm, Gaetano Parascandolo

The role of secondary gas-phase reactions during plasma-enhanced chemical vapor deposition of microcrystalline silicon is a controversial subject. In this paper, we show that the enhancement of such reactions is associated with the improvement of material ...

Modulus anomaly in magnesium matrix composites

Daniele Mari, Robert Schaller, Abu Salek Md. Fahim Chowdhury

Several magnesium matrix composites were investigated by means of mechanical spectroscopy. A modulus anomaly has been observed in the composites reinforced with fibers while the phenomenon does not occur with particles. This effect is attributed to bonding ...

High temperature mechanical spectroscopy of yttria stabilized zirconia reinforced with carbon nanotubes

Daniele Mari, Robert Schaller, Mehdi Mazaheri

High temperature mechanical properties of zirconia reinforced with carbon-nanotubes (CNTs) are studied by mechanical spectroscopy. CNTs limit zirconia grain-boundary sliding (GBS) and consequently deformation. Concurrent grain-growth and plastic deformatio ...

The effect of the orientation of the basal plane on the mechanical loss in magnesium matrix composites studied by mechanical spectroscopy

Daniele Mari, Robert Schaller, Abu Salek Md. Fahim Chowdhury

In metal matrix composites, thermal stresses are relaxed by either interface debonding, crack propagation or dislocation motion. The present paper shows that in the case of a magnesium matrix, interface thermal stresses are relaxed by dislocation motion in ...

Nuclear material investigations by advanced analytical techniques

Manuel Alexandre Pouchon, Johannes Bertsch, Goutam Kuri

Advanced analytical techniques have been used to characterize nuclear materials at the Paul Scherrer Institute during the last decade. The analysed materials ranged from reactor pressure vessel (RPV) steels, Zircaloy claddings to fuel samples. The processe ...
