Comparison of dye-sensitized rutile- and anatase-based TiO(sub-2) solar cells

Article Abstract:

The photoelectric chemical properties of the rutile based solar cell are compared with those of the anatase based cells. Intensity modulated photocurrent spectroscopy and SEM studies indicate that electron transport is slower in the rutile layer than in the anatase layer due to differences in the extent of interparticle connectivity with the particle packing density.

Dye-sensitized TiO2 solar cells: structural and photoelectrochemical characterization of nanocrystalline electrodes formed from the hydrolysis of TiCl4

Article Abstract:

A study was conducted to analyze the structure and photoelectrochemical characteristics of TiO2 films deposited onto SnO2 conducting glass resulting from the ambient hydrolysis of TiCl4. Results indicated that the films supported a rutile structure regardless of annealing temperature. Findings also showed that the films featured rod-shaped particles that grow with increases in annealing temperature.
