Carbonaceous Dye-Sensitized Solar Cell 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...

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...

One-step femtosecond laser patterning of light-trapping structure on dye-sensitized solar cell photoelectrodes†.

Light-trapping patterns were constructed in TiO2 photoelectrodes for dye-sensitized solar cells (DSSCs) by a one-step femtosecond laser structuring method that utilized ablation to create patterns at the surface of nanostructured TiO2 films. As a result, much more light was trapped in the photoelectrodes. Grating and orthogonal-grid patterns were studied, and the light trapping performance was ...
