PVdF-HFP PGE is prepared using PPN solvent.
Tp value of 60 °C achieved for 18 wt% PVdF-HFP PGE.
Rpt values are lower for the gel-state cells using TiO2 NFs than TiC NFs.
Efficiency of 8.38% is obtained for the gel-state cell using 5 wt% TiO2 NFs.
The cell with 18 wt% PVdF-HFP and 5 wt% TiO2 NFs exhibit high stability.
