Abstract
The coupling effect of cis-bis(isothiocyanato)-bis(2,2’-bipyridyl-4,4’-dicarboxylato) ruthenium(II) with triscarboxy-rutheniumterpyridine [Ru(4,4',4"-(COOH)3-terpy) (NCS)3] on the sensitization process of solid-state TiO2|dye|CuI cells was studied. The maximum power conversion efficiencies of 3.0%, 3.8% and 4.98 % were obtained for TiO2|dye|CuI cell sensitized with triscarboxy-rutheniumterpyridine [Ru(4,4',4"- (COOH)3-terpy)(NCS)3], cis-bis (isothiocyanato)-bis(2,2’-bipyridyl-4,4’-dicarboxylato) ruthenium(II) and combination of these dyes. Change of order of dyes was significantly influenced for the efficiency of the solar cells.
