Dye sensitized solar cells (DSSCs) were fabricated using TiO2 synthesized from mesoporous materials as a template such as SBA-15, KIT-6 and MSU-H. The samples were characterized by XRD, FE-SEM, HR-TEM, AFM, Raman spectrum and FT-IR analysis. Systematic studies on the influence of adsorption properties between cis-bis(isothiocyanato)bis(2,2'-bipyridyl-4,4'-dicarboxylato)-ruthenium(II) bis-tetrabutylammonim dye (N719) molecules on the energy conversion efficiency of DSSC are very limited. It has been known that the electron transfer in DSSC is highly influenced by electrostatic and chemical interactions between TiO2 surface and adsorbed dye molecules. The possible anchoring modes for carboxylate group of dye on (101) TiO2 surface are unidentate, chelating and bridging bidentate. This study focused on the systematic analysis of bonding structure between dye molecule and mesostructured TiO2 surface for the performance of DSSC. |
