Quantum dots sensitized nanocrystalline TiO2 solarcells (QDSSCs) are promising thirdgeneration photovoltaic devices. In this study, CdSe quantum dots (Qds) have been prepared via a colloidal route using Mercaptoethanol (Thioglycol) (HOCH2CH2SH) as a capping agent, ZnS/CdSe co-sensitized TiO2 photoanodes for QDSSCs were prepared by ionic layer adsorption and reaction (SILAR) for improving overall photoconversion efficiency. The structural of materials the TiO2/CdSe/ZnS, optical, morphological and photoelectrochemical properties of anode TiO2/CdSe/ZnS thin films were investigated by optical spectrum, TEM, FE- SEM, X-Ray.
