Preparation of transition metal phthalocyanine complexes as photosensitizers for dye solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin

Novel transition metal phthalocyanine-type compounds having an axial ligand which is capable of binding onto a semiconductor such as TiO2, and having at least one peripheral substituent, are active photosensitizers for dye solar cells. Preferred compounds ...

Prediction of Alfven eigenmode dampings in the Joint European Torus

Ambrogio Fasoli

Predictions from a gyrokinetic toroidal plasma model reproduce for the first time the evolution of Alfven eigenmode (AE) dampings over a range of discharges. The coupling between shear-and kinetic-Alfven waves is responsible for the main source of damping ...

Vertical instability in TCV: Comparison of experimental and theoretical growth rates

Jean-Marc Moret, Ivo Furno, Jonathan Bryan Lister

Growth rates of the axisymmetric mode in vertically elongated plasmas in the Tokamak a Configuration Variable (TCV) are measured and compared with numerically calculated growth rates for the reconstructed equilibria. This comparison is made over a range of ...

CO2 Mitigation Through the Use of Hybrid Solar-Combined Cycles.

Daniel Favrat

The integration of a solar collector field generating steam into a conventional combined cycle in order to partially replace the fossil fuel required by the latter results in a substantial reduction in greenhouse gases, in an increase in the return on inve ...

Global Waves in Resistive and Hot Tokamak Plasmas

Laurent Villard, Kurt Appert

Maxwell's equations are solved in a toroidal axisymmetric plasma. The numerical method implemented in the PENN code is based on a formulation in terms of the electromagnetic potentials and a discretization with standard bilinear or bicubic Hermite finite e ...

Spontaneous Emission of Highly Excited Gaas/(Ga,Al)as Quantum-Wells

We report on a transparent analysis of the luminescence spectra of dense electron-hole plasmas confined in GaAs/(Ga,Al)As quantum wells. We fit the spectra using the fact that the total number of particle states does not depend on collision broadening. Fur ...

Lower Hybrid Current Drive in Tore Supra and Jet

Jean-Marc Moret

Recent Lower Hybrid Current Drive (LHCD) experiments in TORE SUPRA and JET are reported. Large multijunction launchers have allowed the coupling of 5 MW to the plasma for several seconds with a maximum of 3.8 kw/cm2. Measurements of the scattering matrices ...

Compression of multi-year meteorological data

Jean-Louis Scartezzini

Dynamic simulation programes require hourly values of solar radiation and ambient temperature forming large files, which are usually difficult to handle with available personal computers (PC). This report describes stochastic models of these variables whic ...
