Abstract

On paper, we have prepared TiO2/MPA/CdSe/ZnS by Successive ionic layer adsorption and reaction (SILAR). The results show that a significant improvement of the light to electric power conversion efficiency of quantum dot sensitized solar cells with a polysulfide electrolyte which can be achieved as using bi functional surface modifiers (SH-R-COOH, Mercaptopropionic acid (MPA)). The injected charge carriers in a CdSe-modified TiO2/MPA film can be collected at a conducting electrode to generate a photocurrent. The TiO2/MPA/CdSe/ZnS composite, employed as a photo anode in a photo electrochemical cell, exhibits a photon to charge carrier generation efficiency η, the short circuit current JSC, open circuit voltage VOC, and fill factor FF correspond to 0.909 %, 6.67 mA/cm2, 0.43 V, 0.31.
