Abstract:

The transparent titanium dioxide (TiO2) electrodes have been modified with cadmium selenite (CdSe) particles by means of chemical deposition method. The sensitization of TiO2 electrode with CdSe particles extends both the optical absorption spectrum and photocurrent action spectrum into the visible region. Furthermore, compared with CdSe bulk materials, a blue shift up to 0.24 eV in both absorption spectrum and photocurrent action spectrum of CdSe/TiO2 electrode was observed and explained in terms of quantum-size effect.

Key words: Titanium dioxide electrode, cadmium selenite particles, Photocurrent spectrum
