Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...
Due to the limiting amount of fossil fuel available and to the continuous growth of the world energy consumption, it becomes important to find alternative energy sources. Hydrogen produced by the photoelectrolysis of water is a perfect candidate as a clean ...
A perylene imide sensitizer and a covalently-linked perylene imide-naphthalene diimide dyad were prepd. and characterized by absorption and emission spectroscopies, electrochem., and spectroelectrochem. These compds. were chemisorbed on nanoporous Ni oxide ...
Four Zn(II)-tetra(carboxyphenyl)porphyrins in soln. and bound to metal oxide (TiO2, ZnO, and ZrO2) nanoparticle films were studied to det. the effect of the spacer length and anchoring group position (para or meta) on their binding geometry and photoelectr ...
Solid-state nanocrystalline solar cells composed of chemical-bath-deposited Sb2S3 (antimony sulfide) as a light absorber layer deposited on nano-porous TiO2 and spiro-MeOTAD as an organic hole-transporting material yielded a solar conversion efficiency of ...
Selective modification of zirconium alkoxide by acetic acid or acetylacetone was used in solution processing of PZT Pb(Zr,Ti)O-3 thin films by 2-methoxyethanol route. EXAFS results clearly show a decrease of Zr-O-Zr links in the acetic acid modified PZT so ...
The dye solar cell, is a novel photoelectrochemical solar cell presenting unique advantages, as the use of low cost materials and the potential simplicity of manufacturing. However, a liquid electrolyte is actually required for the transport of the photoge ...
The main features of the characteristic impedance spectra of dye-sensitized solar cells are described in a wide range of potential conditions: from open to short circuit. An equivalent circuit model was proposed to describe the parameters of electron trans ...
