| Popis: |
The self-organized hollow TiO2hemisphere with a height of 130 nm and a diameter of 200 nm was formed. Highly ordered TiO2nanotube arrays of 200-nm pore diameter and 700-nm length were grown perpendicular to a FTO substrate by infiltrating the alumina pores with Ti (OC3H7)4which was subsequently converted into anatase TiO2. The structure was treated with TiCl4to enhance the photogenerated current and then integrated into the DSSC using a commercially available ruthenium-based dye. The dye-sensitized solar cell using self-organized hollow TiO2hemispheres under porous alumina with TiO2nanotubes inside as the working electrode generated a photocurrent of 5.00 mA/cm2, an open-circuit voltage of 0.58 V and yielding a power conversion efficiency 1.77 times the conventional nanoparticle-based DSSC. |
