Methods to Improve Light Harvesting Efficiency in Dye-Sensitized Solar Cells

Catching the rainbow: light harvesting in dye-sensitized solar cells.

Light-trapping in dye-sensitized solar cells

We demonstrate numerically that photonic crystal dye-sensitized solar cells (DSSCs) can provide at least a factor of one-third enhancement in solar light absorption and power conversion efficiency relative to their conventional counterparts. Our design consists of a lattice of modulated-diameter TiO2 nanotubes filled with TiO2 nanoparticles and interstitial regions filled with electrolyte. This...

Supramolecular light harvesting antennas to enhance absorption cross-section in dye-sensitized solar cells.

Doping a zinc porphyrin based-sensitizer with antenna molecules, axially held by metallo-supramolecular interactions, enhances the light-harvesting efficiency and the overall photo-conversion efficiency of the solar cells by about 30%.

Planar scattering from hierarchical anatase TiO2 nanoplates with variable shells to improve light harvesting in dye-sensitized solar cells.

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.

Dye-sensitized solar cells

The dye-sensitized solar cells (DSC) provides a technically and economically credible alternative concept to present day p–n junction photovoltaic devices. In contrast to the conventional systems where the semiconductor assume both the task of light absorption and charge carrier transport the two functions are separated here. Light is absorbed by a sensitizer, which is anchored to the surface o...
