Abstract

Herein, we are reporting carboxylic acid-functionalized multi-walled carbon nanotubes-polyindole/Ti ₂ O ₃ hybrid nanocomposite (f-MWCNTs-PIN/Ti ₂ O ₃ ) synthesis, phase structure and morphology studies with extended applications. FE-SEM, and TGA results shows that the hybrid nanocomposite having good thermal stability. This hybrid nanocomposite is utilized to prepare a photo-anode of dye-sensitized solar cells (DSSCs). Interestingly, the doped with TiO ₂ (f-MWCNTs-PIN/Ti ₂ O ₃ /TiO ₂ ) hybrid nanocomposite based photo-anode for DSSC reported power conversion efficiency (PCE) of 8.6% and it is about 6% higher than that of un-doped TiO ₂ photo-anode. The corresponding short-circuit photocurrent density (J _sc ) of 18.30 mA cm ⁻² , open circuit voltage (V _oc ) of 0.71 V, fill factor (FF) of 0.66, and dye absorption amount is 0.16 × 10 ⁻⁶ mol cm ⁻² respectively. The obtained results suggest that the hybrid nanocomposite is a suitable photo-anodic material for DSSCs applications.
