Achieving Enhanced Dye-Sensitized Solar Cell Performance by TiCl4/Al2O3Doped TiO2Nanotube Array Photoelectrodes

Carbonaceous Dye‐Sensitized Solar Cell Photoelectrodes

High photovoltaic efficiency is one of the most important keys to the commercialization of dye sensitized solar cells (DSSCs) in the quickly growing renewable electricity generation market. The heart of the DSSC system is a wide bandgap semiconductor based photoelectrode film that helps to adsorb dye molecules and transport the injected electrons away into the electrical circuit. However, charg...

Performance of natural-dye-sensitized solar cells by ZnO nanorod and nanowall enhanced photoelectrodes

In this work, two natural dyes extracted from henna and mallow plants with a maximum absorbance at 665 nm were studied and used as sensitizers in the fabrication of dye-sensitized solar cells (DSSCs). Fourier transform infrared (FTIR) spectra of the extract revealed the presence of anchoring groups and coloring constituents. Two different structures were prepared by chemical bath deposition (CB...

Nanostructured photoelectrodes for dye-sensitized solar cells

Hierarchically structured photoelectrodes for dye-sensitized solar cells

This paper highlights several significant achievements in dye-sensitized solar cells using hierarchically structured photoelectrodes that consist of spherical or one-dimensional assemblies of ZnO or TiO2 nanocrystallites. It shows that, besides providing a large surface area for dye adsorption, more importantly, the hierarchically structured photoelectrodes may improve the solar cell’s performa...
