Kinetic modeling of the reaction and crystallization of acetylsalicylic acid using ATR UV-vis spectroscopy

In industry, spectroscopy is used to monitor batch chemical reactions and to maximize production of a material for a minimum cost. However, there are many challenges involved in using spectroscopic methods to characterize reaction systems that undergo crys ...

Enhanced light harvesting in mesoporous TiO2/P3HT hybrid solar cells using a porphyrin dye

Michael Graetzel, Shaik Mohammed Zakeeruddin, Kevin Sivula, Soo-Jin Moon

We report panchromatic light harvesting in hybrid TiO2/P3HT photovoltaic devices using a porphyrin dye that complements the light absorption of P3HT. The high short circuit photocurrent (12.1 mA cm(-2)) obtained is found to be due, in part, to Forster reso ...

Si-interdiffusion in heavily doped AlN-GaN-based quantum well intersubband photodetectors

Nicolas Grandjean, Denis Martin, Joab Di Francesco

We demonstrate the effect of rapid thermal annealing on heavily Si-doped AlN/GaN quantum wells. After 1000 degrees C annealing during 5, 10, and 20 min, the dominant effect was interdiffusion of Si rather than intermixing between the Al and Ga atoms. Both ...

Absorption Spectra and Excited State Energy Levels of the N719 Dye on TiO2 in Dye-Sensitized Solar Cell Models

Michael Graetzel, Mohammad Khaja Nazeeruddin, Filippo de Angelis

We have investigated the absorption spectrum and the alignment of ground and excited state energies for the prototypical N719 Ru(II) sensitizer adsorbed on an extended TiO2 model by means of high level DFT/TDDFT calculations. The calculated and experimenta ...

Origin of electronic absorption spectra of MLCT-excited and one-electron reduced 2,2 '-bipyridine and 1,10-phenanthroline complexes

Majed Chergui, Andrea Cannizzo, Amal El Nahhas, Cristina Consani

UV-Vis absorption spectra of one-electron reduction products and (MLCT)-M-3 excited states of [(ReCl)-Cl-I(CO)(3)-(N, N)] (N, N = 2,2'-bipyridine, bpy; 1,10-phenanthroline, phen) have been measured by low-temperature spectroelectrochemistry and UV-Vis tran ...

Characterization of the Interface Properties and Processes in Solid State Dye-Sensitized Solar Cells Employing a Perylene Sensitizer

Ulf Anders Hagfeldt

A perylene sensitizer, ID176, was recently reported which performs much better in solid state dye-sensitized solar cells than in those using liq. electrolytes with iodide/tri-iodide as the redox couple. Here, a characterization is presented of the sensitiz ...

Ultraviolet-visible absorption of small silver clusters in neon: Ag-n (n=1-9)

Wolfgang Harbich, Sylvain Lecoultre, Alexandre Rydlo

We present optical absorption and fluorescence spectra in the UV-visible range of size selected neutral Ag-n clusters (n = 1-9) in solid neon. Rich and detailed optical spectra are found with linewidths as small as 50 meV. These spectra are compared to tim ...
