TL;DR: In this article, photo-induced absorption and electrochemical techniques were employed to analyze the charge carrier dynamics that drive photoelectrochemical water oxidation on bismuth vanadate (BiVO4), both with and without cobalt phosphate (CoPi) co-catalyst.

TL;DR: The importance of trap-state energetics for determining the direction of photogenerated charge separation across heterojunctions in films as a function of phase composition is demonstrated and how transient absorption spectroscopy is a useful tool for understanding this behavior is demonstrated.

TL;DR: The study indicates that the efficiencies of solar cells and solar fuels devices can be enhanced by the use of ferroelectric materials.

TL;DR: In this paper, the authors compared the dynamics of photogenerated holes in BiVO4 photoanodes with and without CoPi surface modification, employing transient absorption and photocurrent measurements on microsecond to second timescales.

TL;DR: The kinetics of photoelectrochemical oxidation of methanol, as a model organic substrate, on α-Fe2O3 photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements and it is determined that rate of reaction is second order in the density of surface holes on hematite and independent of the applied potential.
