This paper deals with the synthesis, characterization, and application of lowviscosity ionic liquids as dopants and biopolymers as the host. The biopolymer used in the present study is cornstarch, while the ionic liquid 1-ethyl 3-methylimidazolium thiocyanate (EMIm + SCN − ) is used to develop an electrochemical double-layer capacitor (EDLC) and a dye-sensitized solar cell (DSSC). Different weight ratios of the ionic liquid are incorporated in the polymer host to develop a highly conducting ionic-liquid-doped biopolymer electrolyte (ILBPE). Electrical, structural, and photoelectrochemical characterizations are carried out in detail. Electrochemical impedance spectroscopy (EIS) shows that doping different weight ratios of the ionic liquid enhances the ionic conductivity and conductivity maxima observed at a weight ratio of 80 of the ionic liquid, with an ionic conductivity value of 2.6 × 10 −4 S cm −1 . X-ray diffraction (XRD) and polarized optical microscopy (POM) affirm a reduction in the crystallinity, while thermogravimetric analysis (TGA) shows thermal stability of the ILBPE beyond 200 °C. In addition, the 80% ILBPE-based EDLC exhibits a specific capacitance of 140 F g −1− , an energy density of 23.13 Wh kg −1 , and a power density of 3600 W kg −1 calculated based on galvanostatic charge−discharge (GDC), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV) studies. Moreover, the photovoltaic performance of the DSSC is investigated by using J−V analysis and EIS measurements, while the overall power conversion efficiency is determined as 4% under standard conditions (AM 1.5).

In this study, a new biopolymer electrolyte (BPE) is successfully developed using corn starch complexed with ammonium iodide (NH4I) as host, and low viscosity ionic liquid 1-Ethyl, 3-Methyl Imidazolium Thiocyanate (EMImSCN), as a plasticizer. This ionic liquid doped BPE shows high ionic conductivity of the order 10−4 S/cm and electrochemical stability window more than 3 V, which is suitable for electrochemical application. The ionic transference number (tion) of 0.98 confirms the system to be predominantly ionic in nature. Fourier transform infrared spectroscopy (FTIR) shows complex nature, while polarized optical microscopy (POM) gives us an idea about the semi-crystalline nature of BPE. Maximum conducting ionic liquid doped BPE sandwiched electric double layer capacitor (EDLC) and dye sensitize solar cell (DSSC) shows efficient performance.

At the time, the world critically requires renewable energy. The challenge is figuring out how to meet expanding global energy consumption. Dye‐sensitized solar cells (DSCs) have attracted a lot of interest due to their high energy conversion efficiency, low cost, environmental friendliness, and easy production procedure. First, the study prepares standard cell platinum, which is the most expensive and in low supply. By replacing PVC‐derived porous carbon for expensive platinum in the DSScs counter electrode. The standard efficiency of platinum counter electrode comes out to be 1.94 and efficiency of PVC derived porous carbon electrode comes out to be 0.46.
