An energy conversion efficiency of up to 5.24% has been attained, under AM 1.5 G illumination for a new dye-sensitized solar cell using TH305, as a low cost org. dye, ((CH3)4N)2S/((CH3)4N)2S2, as an org. electrolyte and CoS as counter electrode. ...
Tungsten dioxide (WO2) nanorods were synthesized, which showed good catalytic activity for the redn. of triiodide to iodide. The dye-sensitized solar cell (DSC) using WO2 as a counter electrode (CE) reached a high energy conversion efficiency of 7.25%, whi ...
Block copolymer templating of inorg. materials is a robust method for the prodn. of nanoporous materials. The method is limited, however, by the fact that the mol. inorg. precursors commonly used generally form amorphous porous materials that often cannot ...
Due to their fascinating optical and electronical properties, nanometer-scaled structures play an important role in solar energy conversion [1]. Nanocomposite coatings consist typically of dielectric, semiconducting or metallic nanocrystals embedded in a h ...
The ability to construct well-defined and controlled hierarchical nanostructured porous architectures is desirable for enhancing the performance of electrochem. pseudocapacitors. Here, we propose design rules for improving capacitive energy storage: use of ...
Commercial graphene nanoplatelets in the form of optically transparent thin films on F-doped SnO2 (FTO) exhibited high electrocatalytic activity toward I-3(-)/I- redox couple, particularly in electrolyte based on, ionic liquid (Z952). The charge-transfer r ...
The allotropic forms of carbon (amorphous and polycrystalline graphite, carbon black, fullerenes, nanotubes, graphene) exhibit a large variety of charge transport properties which have been stimulating fundamental and applied research for the development o ...
Fluorescent graphene-based materials have been prepared by a facile ion exchange route comprising the reaction of carboxylated, reduced graphene oxide (c-RGO) with fluorescent anthracene-modified imidazolium salts in water-ethanol solution. The resulting r ...
A simple method has been demonstrated to grow silver nanoparticles on the surface of cellulose fibers. The preparation is based on photo-activation of surface by ultraviolet (UV) photons, followed by chemical reduction of silver nitrate. It is found that t ...
A method to achieve photoinduced tuning of PhC nanocavity modes is discussed and implemented. It is based on light induced oxidation in air atmosphere with very low thermal budget which produces a local reduction of the GaAs membrane effective thickness an ...
