Electrochemically polymerized poly (3, 4-phenylenedioxythiophene) as efficient and transparent counter electrode for dye sensitized solar cells

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Lin Yang, Jiahuan Zhang, Yan Hao

A new conducting polymer poly (3, 4-phenylenedioxythiophene) is synthesized by the electrochemical polymerization technique with different solvents. We find that solvents used in electrochemical polymerization play important roles for the catalytic activit ...

Anomalous Hall and Nernst Effects in Co2TiSn and Co2Ti0.6V0.4Sn Heusler Thin Films

Jean-Philippe Ansermet, Haiming Yu, Sa Tu, Junfeng Hu, Yao Zhang

Magnetotransport (magnetoresistance and anomalous Hall effect) and thermoelectric (Seebeck and anomalous Nernst effect) effects are investigated on epitaxially grown Co2TiSn and Co2Ti0.6V0.4Sn Heusler thin films. An anomalous Nernst coefficient up to 1.8 m ...

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

Andreas Schueler, Anna Krammer, Rosendo Sanjines, 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 ...

Hybrid organic-inorganic H-2-evolving photocathodes: understanding the route towards high performance organic photoelectrochemical water splitting

Michael Graetzel, Matthew Thomas Mayer, Marcel Roland Schreier

A promising, yet challenging, route towards renewable production of hydrogen is the direct conversion of solar energy at a simple and low cost semiconductor/water junction. Despite the theoretical simplicity of such a photoelectrochemical device, different ...

Polarization charge as a reconfigurable quasi-dopant in ferroelectric thin films

Nava Setter, Alexander Tagantsev, Tomas Sluka, Arnaud Robert André Crassous

Impurity elements used as dopants are essential to semiconductor technology for controlling the concentration of charge carriers. Their location in the semiconductor crystal is determined during the fabrication process and remains fixed. However, another p ...

3,4-Ethylenedioxythiophene-based cobalt complex: An efficient co-mediator in dye-sensitized solar cells with poly(3,4-ethylenedioxythiophene) counter-electrode

Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Kazuteru Nonomura, Enrico Polanski

© 2015 Elsevier Ltd. All rights reserved. A mixture of Co(phen)3+/2+ and Co(EtPy)3+/2+ complexes, where EtPy is a terpyridine ligand bearing an 3,4- ethylenedioxythiophene (EDOT) substituent, has been used as redox mediator in dye-sensitized solar cells. T ...

Development of a New Generation of Ammonia Sensors on Printed Polymeric Hotplates

Nico de Rooij, Danick Briand, Francisco Molina Lopez, Andres Felipe Vasquez Quintero, El Hadji Malick Camara

Conducting polyaniline-based chemiresistors on printed polymeric micro-hotplates were developed, showing sensitive and selective detection of ammonia vapor in air. The devices consist of a fully inkjet-printed silver heater and interdigitated electrodes on ...

A quasi core-shell nitrogen-doped graphene/cobalt sulfide conductive catalyst for highly efficient dye-sensitized solar cells

Michael Graetzel

A novel conductive catalyst was designed based on a quasi core shell structure of N-doped graphene/cobalt sulfide. This platinum-free catalyst shows high catalytic activity and conductivity owing to close interactions between the core (cobalt sulphide) and ...
