The dye-sensitized nanocrystalline injection solar cell employs transition metal complexes for spectral sensitization of mesoporous TiO(2) films together with suitable redox electrolytes or amorphous organic hole conductors. Light harvesting occurs efficiently over the whole visible and near-IR range due to the very large internal surface area of the films. Judicious molecular engineering allow...

Hierarchical anatase TiO(2) nanoplates with tunable shell structure were developed as the novel planar scattering layer in dye-sensitized solar cells, showing improved cell performance due to the enhanced light harvesting capability.

Abstract Dye-Sensitized Solar Cells (DSSC), a 3rd generation solar cell has gained huge attention in the field of photovoltaics as substitute for silicon cell. The performance DSSC mainly depends on all important components such transparent conductive oxide substrate, cathode, photo-anode, dye, and electrolyte. Additionally, sensitizing dyes also perform vital role absorption light conversion e...

3,4-Ethylenedioxythiophene and bis[2-(2-methoxyethoxy)ethoxy]thiophene bridged donor-acceptor molecules for dye-sensitized solar cells have been synthesized, one of which achieved a solar-to-energy conversion efficiency of 7.3%, compared to 7.7% optimized for N719 dye.

Transparent nickel doped cobalt sulfide was fabricated on a SnO2:F electrode and tested as an efficient electrocatalyst and as an alternative to the expensive platinum counter electrode. In order to investigate how this electrode could affect the electrical characteristics of a dye-sensitized solar cell, we manufactured cells with the same TiO2 photoanode sensitized with dye (N719) and employin...

Herein we report a theoretical analysis of the efficiency of dye sensitized solar cells in which colloidal crystals are introduced in different configurations. We find that piling up different lattice constant crystals leads to light harvesting enhancement in the whole dye absorption range. We provide the optimum structural features of such photonic crystal multilayer needed to achieve a photoc...

in the current study, pure tio2 and cr-doped tio2 (cr@tio2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous tio2 electrodes for dye-sensitized solar cells (dsscs). it is hypothesized that the advantages of the doping of the metal ions into tio2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...
