Abstract

Porous TiO₂ nanoparticles were prepared by soft template assisted hydrothermal method. XRD pattern confirms the formation of tetragonal anatase phase of TiO₂. HRSEM images show homogeneous spherical shaped porous TiO₂ nanoparticles. UV-Visible spectrum ensures broad absorption in ultraviolet regime with absorption maximum at 291 nm. Nyquist plot reveals that decrease in electrical resistance with increasing applied potential results in enhancing the conductivity. The interfacial charge transfer resistance and electron recombination lifetime of the fabricated DSSC was examined using EIS analysis. Photovoltaic performance of the device was studied using standard solar simulator and the power conversion efficiency of ∼2.3% was achieved.
