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 ...

CuInGaS2 photocathodes treated with SbX3 (X = Cl, I): the effect of the halide on solar water splitting performance

Kevin Sivula, Florian Le Formal, Pauline Bornoz, Xavier Adrian Jeanbourquin, Wiktor Stefan Bourée, Xiaoyun Yu, Mathieu Steven Prévot, Nestor Guijarro Carratala

The realization of photoelectrochemical tandem cells for efficient solar-to-hydrogen energy conversion is currently impeded by the lack of inexpensive, stable, and efficient photocathodes. The family of sulfide chalcopyrites (CuInxGa1-xS2) has recently dem ...

A Bottom-Up Approach toward All-Solution-Processed High-Efficiency Cu(In,Ga)S

Kevin Sivula, Florian Le Formal, Pauline Bornoz, Xavier Adrian Jeanbourquin, Wiktor Stefan Bourée, Xiaoyun Yu, Mathieu Steven Prévot, Nestor Guijarro Carratala

The development of solution-processable routes to prepare efficient photoelectrodes for water splitting is highly desirable to reduce manufacturing costs. Recently, sulfide chalcopyrites (Cu(In,Ga)S-2) have attracted attention as photocathodes for hydrogen ...

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

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

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 ...

A Bismuth Vanadate-Cuprous Oxide Tandem Cell for Overall Solar Water Splitting

Michael Graetzel, Kevin Sivula, Pauline Bornoz, Stanley David Tilley

Through examination of the optoelectronic and photoelectrochemical properties of BiVO4 and Cu2O photoelectrodes, we evaluate the feasibility of a BiVO4/Cu2O photoanode/photocathode tandem cell for overall unassisted solar water splitting. Using state-of-th ...

A selective chemiluminescence detection method for reactive oxygen species involved in oxygen reduction reaction on electrocatalytic materials

Christos Comninellis, Pauline Bornoz

An original selective and quantitative detection method for direct access to reactive oxygen species (ROS) generated in near-neutral aqueous solutions during transient electrochemical experiments is described herein. Several chemiluminescent probes, which ...
