DYE-SENSITIZED SOLAR-CELL WITH CEO2 AND MIXED CEO2 SNO2 PHOTOANODES/

Dye-sensitized CeO2 and mixed CeO2/SnO2 film electrodes using a Ru(by) -complex were used as photoanodes in photoelectrochemical solar cells. The cells were prepared following the description by Gratzel et al., but using CeO2 and mixed CeO2/SnO2 film instead of TiO2 film. The reas ons why CeO2 and mixed CeO2/SnO2 were chosen are the similar optical a nd electrical properties of CeO2 and TiO2 films and because of a suita ble, new method of dip-coating preparation which has recently been pub lished. The authors consider this paper to fall in the category of pre liminary notes, regarding new results with CeO2 and CeO2/SnO2 used for the first time as photoanodes in a new generation of nanophase solar cells.
