A novel titanium dioxide paste based on Pechini sol-gel method and nanocrystalline TiO2 powder has been successfully developed and tested. The paste enables the formation of sponge like structure of the TiO2 layer i.e. highly porous and at the same time well connected TiO2 network. The layers have been used to assemble dye sensitized solar cells (DSSC) with two ruthenium complex based dyes, N71...

Novel heteroleptic ruthenium complexes--RD1, RD5, RD10 and RD11--with ligands based on benzimidazole were synthesized and characterized for application to dye-sensitized solar cells (DSSC); the remarkable performance of RD5-based DSSC is understood for its superior light-harvesting ability and slower charge-recombination kinetics.

Neighboring metal nanoparticles influence photovoltaic and photocatalytic behavior of semiconductor nanostructures either through Fermi level equilibration by accepting electrons or inducing localized surface plasmon effects. By employing SiO(2)- and TiO(2)-capped Au nanoparticles we have identified the mechanism with which the performance of dye-sensitized solar cells (DSSC) is influenced by t...

Current work employs dye extracted from leaves of Costus woodsonii as a new sensitizer for dye-sensitized solar cells (DSSCs). The leave was in three different solvents namely ethanol, methanol, and acetone. Extraction carried out by the freezing method. DSSCs with configuration TiO2/dye/electrolyte/Pt were assembled. dyes DSSC methanol extract has an efficiency 0.23 % short-circuit current den...

Dye-sensitized solar cell (DSSC) is a promising solution to global energy and environmental problems because of its clean, low-cost, high efficiency, good durability, and easy fabrication. However, enhancing the efficiency of the DSSC still is an important issue. Here we devise a bifacial DSSC based on a transparent polyaniline (PANI) counter electrode (CE). Owing to the sunlight irradiation si...

The dye-sensitized solar cell (DSSC) has been proven to have a good chance to become a notable competitor for solar cells based on today technology of p-n junction. The principle of operation of DSSC solar cells in comparison with conventional semiconductor solar cells where light absorption and charge carrier transport are done by the semiconductor is different. In DSSC these two tasks are sep...

two organic compounds (sc-23=(e)-2-cyano-3-(2,3-dimethoxyphenyl) acrylic acid and sc-25=(e)-2-cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. they shows a short-circuit current density (jsc) of 2.08 and 1.81 ma cm-2, an open circuit voltage (voc)...

In a dye-sensitized solar cell (DSSC), the amount of light absorption dependson the design of the pigments, which determines the strength of light absorption and theoptical range of the cell. In this paper, we have constructed and studied two fairly similarpattern of DSSCs in structure. The thickness of TiO2 used for both cells is taken to be 2μm. We have used an industrial N719 dye for one of ...

One-dimensional titania nanostructures can serve as a support for light absorbing molecules and result in an improvement in the short circuit current (Jsc) and open circuit voltage (Voc) as a nanostructured and high-surface-area material in dye-sensitized solar cells. Here, self-assembled amyloid-like peptide nanofibers were exploited as an organic template for the growth of one-dimensional tit...
