Integrated Electronic, Optical, and Structural Features in Pseudo-3D Mesoporous TiO_2-X Delivering Enhanced Dye-Sensitized Solar Cell Performance.

ABSTRACT: The performance of a dye-sensitized solar cell (DSSC) is strongly affected by optical, structural, and electronic features of a photoanode. In this article, meso-TiO_2-X was prepared by a solution combustion method and hydrogenation at high pressure. The properties of DSSCs with meso-TiO_2-X photoanodes were investigated by photocurrent-voltage, incident photon-to-current conversion efficiency, and electrochemical impedance spectroscopy (EIS) measurements. The meso-TiO_2-X materials exhibit new electronic states and aided to absorb in the visible region because of the narrow band gap. Facile charge transfer from the N719 dye to the TiO₂ photoanode was assisted by low-lying mid-gap states. Electrically integrated nanoparticles, w
