Abstract
The main purpose of this research is to study co-sensitization in the dye-sensitized solar cell (DSSC) .or DSSC, photon-to-electron conversion efficiency is depending on the dye absorption spectrum and the shifting rate of electron from dye to electrode. The absorption UV-vis spectrum of dyes in DSSC is generally in 400nm-600nm region ,but it is weak beyond 600nm.Therefore ,in this study we blend dyes in order to extend the range of light absorption and improve the efficiency of DSSC further.he common phthalcyano ruthenium complex, bis(4-carboxypyridine)(phthalocyanainato) ruthenium(II) in near IR region are chosen to fabricate co-sensitized DSSC .ruthenuim complex, N719 (cis-di(thiocyanato)-bis(2,2''-bipyridyl -4,4''-dicarboxylic acid)-ruthenium(II)) in blue light region, and We want to extend light absorption and improve efficientcy by this process. he results reveal that the energy band of N719 and bis(4-carboxypyridine)(phthalocyanainato) ruthenium(II) can macth well.So the efficiency of DSSCs is enhancing near 10％.
