Nanocomposite polymer electrolyte based on rice starch/ionic liquid/TiO2 nanoparticles for solar cell application

Nanocomposite polymer electrolyte (NCPE) was prepared using solution cast technique. Rice starch (RS), lithium iodide (LiI), 1-methyl-3-propylimidazolium iodide (MPII) as ionic liquid and TiO2 nanopowder (RS:LiI:MPII:TiO2) were introduced to prepare the sample. The conductivity of 3.63 × 10−4 S/cm was achieved by introducing 30 wt.% of 1-methyl-3-propylimidazolium iodide (MPII) as ionic liquid and 2 wt.% of TiO2. Temperature-dependent conductivity and dielectric behavior were analyzed in this work. Dye sensitized solar cell was fabricated using the nanocomposite film for this sample and analyzed.
