TL;DR: In this paper, it was shown that very low energy losses occur when a suitable redox catalyst mediates the oxidation step, showing that the chlorine generation from NaCl evolution takes place.

TL;DR: Ma et al. as discussed by the authors revealed the underlying mechanisms of facet-dependent degradation of formamidinium lead iodide (FAPbI3) films and showed that the (100) facet is substantially more vulnerable to moisture-induced degradation than the (111) facet.

TL;DR: Etude de polysavons derives de la polyvinyl-4 pyridine fonctionnalises avec le trisbipyrydyl ruthenium comme sensibilisants a la lumiere visible for the formation d'hydrogene catalytique par le photocatalyseur TiO 2 platinise as discussed by the authors.

TL;DR: Ruthenium dioxide deposited onto TiO2 particles catalyzes vigorous reduction of bromate ions to bromine (or bromide) by water and simultaneous generation of stoichiometric amounts of oxygen.

Abstract: The development of new light harvesting materials is a key issue for the progress of the research on organic & hybrid photovoltaics. Here, we report a new class of organic sensitizers based on the bi-fluorenylidene moiety as π-linker within the donor–π-linker–acceptor (D–π–A) scheme. The new dyes are endowed with electron donor and electron acceptor units at strategic positions in order to improve their electronic and light-harvesting properties. The comprehensive study of these compounds through the use of different experimental and theoretical techniques, provides an in-depth understanding of their electronic and photophysical properties, and reveal their interest as photovoltaic materials.
