Photonic and Optoelectronic Devices Based on Mesoscopic Thin Films

Michael Graetzel, Shaik Mohammed Zakeeruddin, Kuppuswamy Kalyanasundaram

Dye-sensitized solar cells (DSCs) are one of the most promising environmental friendly and low material costs photovoltaic devices. DSCs accomplish the separation of the optical absorption and charge separation processes by the association of a sensitizer ...

Strategies to Optimizing Dye-Sensitized Solar Cells

Sophie Wenger

Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...

Influence of Sodium Cations of N3 Dye on the Photovoltaic Performance and Stability of Dye-Sensitized Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Shaik Mohammed Zakeeruddin

We report on the effect of substituting the two tetrabutyl ammonium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye-sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non-volatile ...

Using Nanocavity Plasmons to Improve Solar Cell Efficiency

Stefan Guldin

Although in principle very promising, photovoltaic technology has so far failed to deliver robust high efficiency modules at affordable prices. Despite considerable research, high efficiency silicon based cells remain expensive, while the more recent organ ...

All the Disorder Mechanisms in the 13:58 Phases Come Together. Out of the Modulated Confusion Rises the Remarkable Phase Ce12.60Cd58.68(2)

The compound

Ce_{12.60}Cd_{58.68(2)}

is a metrically commensurate representative of the incommensurately modulated phase

Ce_{13}Cd_{57+\delta}

. It is most likely a lock-in phase. The structure, which was solved using seeding of the modulation from thos ...

Growth of single-crystalline KNbO3 nanostructures

Nava Setter, László Forró, Arnaud Magrez, Jin Won Seo

This communication reports on the growth of highly uniform KNbO3 nanowires exhibiting a narrow diameter distribution around 60 nm and a length-to-width ratio up to 100. The nanowires were prepared by a hydrothermal route, which enables simple, gram-scale p ...

Thermal modeling of a small anode supported solid oxide fuel cell

François Maréchal, Daniel Favrat, Jan Van Herle, Diego Larrain

A combined thermal and simple kinetic model is applied to a small single solid oxide fuel cell (SOFC, 20 cm2 square cell of anode supported electrolyte with 1 cm2 active area). The aim was to compute the temperature field to analyze the operating condition ...

KNb4O5F and NbO2 crystal structures. Structural aspect of chemical decomposition of K2-xNb4O3(O,F)(3)F in the melt of sodium and potassium chlorides

Gervais Chapuis, Alla Arakcheeva

The structures of the KNb4O5F (I) (synthesized for the first time) and the NbO2 (II) phases formed together with NbO during decomposition of reduced oxofluoroniobate K2-xNb4O3(O,F)(3)F (III) in the (NaCl + KCl) melt are studied by X-ray methods. The tetrag ...

High-Temperature Heat-Capacity And Phase-Transitions Of CaTiO3 Perovskite

Philippe Gillet

Drop-calorimetry measurements performed on CaTiO3 perovskite between 400 and 1800 K have shown the occurrence of two overlapping phase transitions at 1384 and 1520 K. The 1384 K transition shows a lambda-type C(p) variation with a very sharp C(p) decrease ...
