Abstract

This study combines Au nanoparticles with TiO₂ nanoparticles to form a Schottky barrier, and applies it to the photoelectrode thin film of dye-sensitized solar cells (DSSCs). First, commercial TiO₂ powder (Degussa P25) is put in the alkaline solution to prepare for TiO nanotubes (Tnt) by using hydrothermal treatment. Tnt are sintered at 550 °C to obtain Tnt-C550 particles. In addition, TiO₂ nanoparticles (H180) prepared by subjecting Tnt to two cycles of hydrothermal treatment. H180 served as the first layer, and Tnt-C550 as the second. The third layer adopts salt reduction method to prepare for Au nanoparticles. Experimental results show that the DSSCs prepared with three layers of photoelectrode thin films (H180/Tnt-C550/Au) enhanced the light-to-electricity efficiency of DSSCs by as high as 21% (6.34-7.65%).
