Abstract

Performance of dye-sensitized solar cells (DSSCs) based on TiO ₂ nanotubes (NTs) filled with TiO ₂ nanoparticles (NPs) was studied as a function of NTheight (h). TheNT height was varied in the range of 1.5-7.0 μm, while the NT diameter was kept constant at ∼80 nm. The studies showed that DSSC efficiency, current density, and fill factor linearly increased with h and ranged in 1.76-6.5%, 3.62-13.2 mA/cm ², and 0.66-0.76, respectively, within the h range studied. The electrochemical impedance spectroscopy was also performed to study DSSC electron transport properties. Based on both photovoltaic and electrochemical impedance spectroscopy data, the results were explained as being due to the increased dye loading that led to higher light-harvesting efficiency.
