Electrical, structural, thermal, and optical studies are carried out in detail and presented in this communication. Maximum conducting IL-incorporated biopolymer electrolyte film has been sandwiched between electrodes to develop EDLC and DSSC. The sandwich-structured EDLC delivers a high specific capacitance of 250 F/gram while DSSC shows 1.44 % efficiency at one sun condition.

Electrochemical impedance data indicates that increasing ionic liquid into polymer electrolyte matrix increases ionic conductivity and the maximum value of ionic conductivity was obtained at 150 wt% TBMPI, having conductivity value of 8.3 × 10−5 S cm−1. The dielectric measurement supports our conductivity data. Ionic transference number measurement affirms this system to be predominantly ionic in nature, while electrochemical stability window (ESW) was found to be 3.4 V. Polarized optical microscopy (POM) along with differential scanning calorimetry (DSC) suggest suitability of TBMPI as plasticizer, while infrared spectroscopy (FTIR) confirms ion interaction, complexation, and composite nature. The thermogravimetric analysis (TGA) shows thermal stability of these ionic liquid-doped polymer electrolytes (ILDPEs). Using maximum conducting ILDPE, a sandwiched supercapacitor has been fabricated which shows stable performance as high as 228 Fg−1 using cyclic voltammetry (CV).

These IL-doped solid polymer electrolyte were prepared using solution cast technique. Various characterisation techniques have been utilized to evaluate the qualitative and quantitative estimation of polymer electrolyte like Polarized microscopy (POM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Linear sweep voltammetry (LSV), Ionic transference no. (tion) and Impedance spectroscopy. Doping IL increases conductivity and highest achieve at 8 wt% of BMPyrrOTF with conductivity value reaches upto 4.15 × 10–5 S/cm at. Using Wagner’s polarization method, Ionic transference measurement support ionic conduction while stable potential window has further affirmed good electrochemical stability of films. The highest conducting IL-enriched polymer electrolyte sandwiched low-cost dye-sensitized solar cells (DSSCs) and electric double layer capacitors (EDLCs) have been developed, and their performance is conveniently appropriate.
