Tailor-Making Low-Cost Spiro[fluorene-9,9 '-xanthene]-Based 3D Oligomers for Perovskite Solar Cells

Ulf Anders Hagfeldt, Jiahuan Zhang, Liang Wang, Peng Liu

The power-conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have increased rapidly from about 4% to 22% during the past few years. One of the major challenges for further improvement of the efficiency of PSCs is the lack of sufficiently good ...

High energy density MnO4– / MnO42– redox couple for alkaline redox flow batteries

Hubert Girault, Pekka Eero Peljo, Alejandro Nicolás Colli

The MnO4–/MnO42– redox couple has a positive redox potential, high electrochemical reversibility and high solubility, up to 3.62 M at room temperature. Careful optimization of the electrolyte composition and the potential limits eliminates the side reactio ...

Scalable Row/Column Addressing of Silicon Photonic MEMS Switches

Niels Quack

In this letter, we demonstrate a scalable addressing scheme for silicon photonic MEMS switches. For a crossbar architecture switch fabric of dimension N x N, the row/column addressing scales with 2 . N electrodes, much reduced from the N-2 electrodes in in ...

Parylene-Based Hollow Nanomechanical Resonators For Bioapplications

Luis Guillermo Villanueva Torrijo, Annalisa De Pastina, Tom Larsen, Antoine Nicolas Désiré Aupée

We present the fabrication of parylene-based hollow nanomechanical resonators, following a simple two step fabrication process with a thermal budget of less than 120°C. This process is ideal for fast prototyping and compatible with most materials used in m ...

Wireless Monitoring of Endogenous and Exogenous Biomolecules on an Android Interface

Giovanni De Micheli, Sandro Carrara, Francesca Stradolini, Irene Taurino, Cristina Boero, Camilla Baj-Rossi, Grégoire Casimir Joseph Surrel, Stefano Riario

Monitoring patients in intensive care units is generally expensive and time consuming. A prompter medical intervention for those critical patients is a key factor for their safety. Therefore, a system that offers immediate visualization of the monitored da ...

Influence of anodization time on the surface modifications on alpha-Fe2O3 photoanode upon anodization

Artur Braun, Yelin Hu

In searching for a suitable semiconductor material for hydrogen production via photoelectrochemical water splitting, alpha-Fe2O3 received significant attention as a promising photoanode due to its band gap (similar to 2.1 eV), good stability, low cost, and ...

Contact potentials, Fermi level equilibration and surface charging

Hubert Girault, Pekka Eero Peljo

This paper focuses on contact electrification from thermodynamic equilibration of the electron electrochemical potentials of two conductors upon contact. The contact potential difference generated in bimetallic macro- and nanosystems, the Fermi level after ...

Fixed Energy X-ray Absorption Voltammetry and Extended X-ray Absorption fine Structure of Ag nanoparticle electrodes

Christos Comninellis

FEXRAV (Fixed Energy X-ray Absorption Voltammetry) has been recently introduced as a powerful tool in electrochemistry. It consists in measuring the X-ray absorption coefficient at a fixed X-ray energy while the electrochemical potential of the material un ...

Highly efficient dye-sensitized solar cells achieved through using Pt-free Nb2O5/C composite counter electrode and iodide-free redox couples

Ulf Anders Hagfeldt, Weiwei Zhang, Wenyan Li

To improve the catalytic activity of Nb2O5, a composite Nb2O5/C (Nb2O5 imbedded in carbon support) is synthesized with a simple in situ method and then introduced the composite into dye-sensitized solar cells (DSCs) as a counter electrode (CE) catalyst. Ba ...
