Design and Realization of a Novel Optically Disordered Material: A Demonstration of a Mie Glass
(Wiley-Blackwell, 2017)
Herein, a diffusive material presenting optical disorder is introduced, which represents an example of a Mie glass. Comprising spherical crystalline TiO nanoparticles randomly dispersed in a mesoporous TiO matrix, it is ...

Structural elucidation of Β-(Y,Sc) 2Si 2O 7: Combined use of 89Y MAS NMR and powder diffraction
(International Union of Crystallography, 2011-08)
Although the structures of pure Sc2Si2O7 and Β-Y 2Si 2O 7 have been described in the literature using the C2/m space group, 29Si magic angle spinning (MAS) NMR measurements of the intermediate members of the Sc 2Si 2O 7-Β- ...

Plasmonic Nanoparticles as Light-Harvesting Enhancers in Perovskite Solar Cells: A User’s Guide
(American Chemical Society, 2016)
In this Perspective we discuss the implications of employing metal particles of different shape, size, and composition as absorption enhancers in methylammonium lead iodide perovskite solar cells, with the aim of establishing ...

Maximized performance of dye solar cells on plastic: a combined theoretical and experimental optimization approach
(Royal Society of Chemistry (Great Britain), 2016)
We demonstrate that a combined optimization approach based on the sequential alternation of theoretical analysis and experimental realization gives rise to plastic supported dye solar cells for which both light harvesting ...

Strong quantum confinement effects in SnS nanocrystals produced by ultrasound-assisted method
(Springer, 2013)
Nanocrystalline SnS powder has been prepared using tin chloride (SnCl2) as a tin ion source and sodium sulfide (Na2S) as a sulfur ion source with the help of ultrasound irradiation at room temperature. The as-synthesized ...

Efficient bifacial dye-sensitized solar cells through disorder by design
(Royal Society of Chemistry (Great Britain), 2016)
Herein we realize an optical design that optimizes the performance of bifacial solar cells without modifying any of the usually employed components. In order to do so, dielectric scatterers of controlled size and shape ...
