Elucidating the role of chlorine in perovskite solar cells

Ulf Anders Hagfeldt, Jingshan Luo, Gang Wang

It has been proposed that introducing the chlorine anion into a CH3NH3PbI3 perovskite material can substantially improve the materials properties as well as the solar cell performance. To elucidate the role of chlorine in perovskite solar cells (PSCs), her ...

Assemblies of gold nanoparticles at liquid-liquid interfaces : from liquid optics to electrocatalysis

Evgeny Smirnov

The interface between two immiscible liquids, i.e. oil and water, is an extremely attractive scaffold to self-assemble nanoparticles (NP) in arranged films. The liquid-liquid interfaces (LLIs) are defect-free and pristine by the nature, they are transparen ...

In situ photoelectron spectroscopic characterization of reactively sputtered, doped vanadium oxide thin films

Andreas Schueler, Rosendo Sanjines, Anna Krammer, Olivia Valérie Charlotte Bouvard

Thin films of pure vanadium oxide (VOx) and Ge doped vanadium oxide (VOx:Ge) have been deposited by reactive magnetron sputtering on Si (100) substrates. These films were characterized by means of in situ X-ray photoelectron spectroscopy and ultraviolet ph ...

In situ core-level and valence-band photoelectron spectroscopy of reactively sputtered tungsten oxide films

Andreas Schueler, Anna Krammer, Olivia Valérie Charlotte Bouvard

In this paper, we study tungsten oxides deposited by reactive magnetron sputtering. The total working pressure during deposition was varied in order to obtain different morphology. The effects on the electronic properties and chemical composition were stud ...

Dimensional effects on the tunneling conductivity of gold-implanted nanocomposite films

Claudio Grimaldi

We study the dependence of the electrical conductivity on the gold concentration of Au-implanted polymethylmethacrylate (PMMA) and alumina nanocomposite thin films. For Au contents larger than a critical concentration, the conductivity of Au-PMMA and Au-al ...
