Title: Acid-free approach towards the growth of vertically aligned TiO2 nanorods as an efficient photoanode for dye-sensitized solar cells

Journal Article · · Materials Research Bulletin

Highlights: • Vertically aligned TiO{sub 2} NRs are fabricated by an acid-free hydrothermal approach. • Study the effect of TiO{sub 2} NRs growth parameters on its structural/optical properties. • The optimized TiO{sub 2} NRs were employed as an efficient photoanode for DSSCs. • An optimal PCE of 2.45% was achived by DSSC with TiO{sub 2} NRs with heights of ∼1.56 μm. - Abstract: We synthesized the closely packed titanium dioxide nanorods (TiO{sub 2} NRs) on fluorine-doped tin oxide (FTO) glass by a facile and cost-effective hydrothermal method. The TiO{sub 2} NRs were further utilized as a photoanode for dye-sensitized solar cells (DSSCs). For hydrothermal growth of TiO{sub 2} NRs, we utilized an acid-free reaction medium instead of a strong acidic medium, which can reduce the equipment cost as well as the environmental damages. Before employing these TiO{sub 2} NRs for DSSCs as a photoanode, the effects of hydrothermal growth parameters on the structural and optical characteristics of TiO{sub 2} NRs/FTO glass were investigated. Eventually, the TiO{sub 2} NRs with optimized height and diameter were employed to DSSCs and their photovoltaic characteristics were examined.
