Verification of high efficiencies for the Graetzel-cell. A 7% efficient solar cell based on dye-sensitized colloidal TiO2 films

Dye-sensitized colloidal TiO2 film electrodes using a Ru 2,2'-bipyridyl-4,4'-dicarboxylic acid complex were used as photoanodes in photoelectrochem. solar cells. The cells were prepd. following the description by M.K. Nazeeruddin, et al, (1993). An overall light-to-elec. energy conversion efficiency of 7% in 1000 W/m2 light from the ELH lamp was obtained. Practical problems in the prepn. procedure of the solar cell module has so far made long time stability tests impossible. Future developments of the cell are discussed.
