Researchers from Department of Engineering Sciences Report on Findings in Nanostructures (Effect of Acidic Treatment On Dssc Performance of Tio2 Nanostructures)

Article Description

The effects of the acidic treatment on the photovoltaic properties of the dye-sensitized solar cell (DSSC) were investigated. TiO nanostructure was prepared by chemical bath deposition method and the surface was modified by various acidic treatments like hydrochloric acid (HCl), nitric acid (HNO), sulphuric acid (HSO), and acetic acid (CHCOOH). The results exhibited a significant influence of acidic treatments on structural, morphological, optical, electrochemical, and photovoltaic properties. XRD analysis confirms the formation TiO nanostructure electrodes. After acidic surface treatment photoconversion efficiency increases from 1.97% (for pristine electrode) to 3.23% (for acetic acid surface treatment). With respect to that electron lifetime increased from 0.34 to 0.54 ms and charge transfer resistance decreased from 25.76 Ω cm (pristine TiO electrode) to 17.96 Ω cm.
