Demonstration and Characterization of Ladder-Type Conjugated Polymer Photoanode for Direct Light-Driven Water Oxidation

Pauline Bornoz

Energy production is not only a scientific challenge. It also has implications on human and animal health, global environment, and international politics and economics. In order to reduce these effects, the development of a new clean and renewable method i ...

EPFL2017

Organic semiconductor materials have been widely applied in optoelectronic devices to replace their inorganic counterparts and explore new fields of applications. Due to their high extinction coefficients, chemical tunability and solubility, cyanine dyes a ...

Enhancing the Performance of a Robust Sol-Gel-Processed p-Type Delafossite CuFeO2 Photocathode for Solar Water Reduction

Kevin Sivula, Nestor Guijarro Carratala, Mathieu Steven Prévot

Delafossite CuFeO2 is a promising material for solar hydrogen production, but is limited by poor photocurrent. Strategies are demonstrated herein to improve the performance of CuFeO2 electrodes prepared directly on transparent conductive substrates by usin ...

Solar Hydrogen Production by Amorphous Silicon Photocathodes Coated with a Magnetron Sputter Deposited Mo

Christophe Ballif, Xile Hu, Björn Niesen, Laurent Liardet, Carlos Gilberto Morales Guio

Coupling of Earth-abundant hydrogen evolution catalysts to photoabsorbers is crucial for the production of hydrogen fuel using sunlight. In this work, we demonstrate the use of magnetron sputtering to deposit Mo2C as an efficient hydrogen evolution reactio ...

Direct Light-Driven Water Oxidation by a Ladder-Type Conjugated Polymer Photoanode

Kevin Sivula, Nestor Guijarro Carratala, Xiaoyun Yu, Mathieu Steven Prévot, Pauline Bornoz

A conjugated polymer known for high stability (poly[benzimidazobenzophenanthroline], coded as BBL) is examined as a photoanode for direct solar water oxidation. In aqueous electrolyte with a sacrificial hole acceptor (SO32-), photoelectrodes show a morphol ...

Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes

Michael Graetzel, Stanley David Tilley, Ludmilla Steier

Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under-and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were clearly shown; however, the mechani ...
