Dye-sensitized solar cells (DSCs) are one of the most promising environmental friendly and low material costs photovoltaic devices. DSCs accomplish the separation of the optical absorption and charge separation processes by the association of a sensitizer ...

Using sun as the energy source, natural photosynthesis carries out a number of useful reactions such as oxidation of water to molecular oxygen and fixation of CO2 in the form of sugars. These are achieved through a series of light-induced multielectron-tra ...

A method for the simultaneous production of hydrogen and oxygen from water by the visible light irradiation of a water solution containing photosensitizer, an electron relay and a suitable combination of redox catalysts.

A photoelectrochemical system for conducting endoergic chemical processes driven by light energy. This system consists essentially of an illuminated halfcell and a darkened halfcell joined via electrodes and an external circuit to allow for the transport of electrons. Also, the said halfcells are joined by an ion conducting junction so as to allow for the transport of ions. The illuminated halfcell contains a photosensitizer, an electron relay substance and a catalyst, and the darkened halfcell may contain

The rich and diverse aspect of nanomaterials for energy conversion and storage has been the research topic for many researchers. Photovoltaic solar cells for the direct conversion of sunlight to electricity can be grouped under three generations. One appro ...

A simple mononuclear cyclometallated iridium(III) complex exhibits white photo- and electro-luminescence in the wavelength range from 440 to 800 nm, which originates from a single emitting excited state of mixed character. ...

Pyrene fluorescence intensity and conductivity measurements were used to determine the cmc of two monomeric surfactants namely, dodecyltrimethylammonium bromide and cetyltrimethylammonium bromide as well as two gemini surfactants, 16-3-16 2Br and 16-4-16 2 ...

L'hydrogène et le soufre élémentaire sont produits par irradiation par la lumière visible de solutions d'hydrogène sulfuré ou de sulfure de métaux en presence d'un catalyseur consistant en une matière semiconductrice, telle que le sulfure de cadmium, recouverte d'une couche transparente d'oxyde de ruthénium.

Le produit de présente sous forme de particules distinctes ou sous forme d'une couche incorporée à une électrode. Il consiste en une matière semiconductrice sujette à la photocorrosion, par exemple du sulfure de cadmium. Afin de prévenir cette photocorrosion, la surface de la matière semiconductrice qui est destinée à être illuminée est recouverte d'une couche transparente de RuO2, de IrO2 ou d'un mélange de RuO2 et de IrO2. Le produit peut être utilisé pour la conversion de l'énergie solaire en énergie éle
