Biopolymer electrolytes based on dextran from Leuconostoc mesenteroides doped with ammonium nitrate (NH 4 NO 3) are synthesized via a solution cast method. Fourier transform infrared analysis is used to determine the complexation between cation from the salt with functional groups of dextran. The ionic conductivity of undoped dextran film at room temperature is identified as (8.24 ± 0.31) × 10 −11 S cm −1. A conductivity of (3.00 ± 1.60) × 10 −5 S cm −1 is achieved with the inclusion of 20 wt% NH 4 NO 3 to the pure dextran film. The conductivity at a high temperature of the electrolyte obeys Arrhenius theory. Field emission scanning electron microscopy results show that the highest conducting sample has a porous surface. Results from the dielectric study show a non-Debye characteristic.

“…Biopolymers are extracted from a wide range of resources such as cellulose derivatives, chitosan, carrageenan, pectin, starch and lignin [4][5][6][7][8][9][10]. These polymers possess a lone pair electron of the heteroatom such as nitrogen or oxygen and hence ionic dopant can be solvated [11].…”

Despite the fact that perovskite solar cells (PSCs) have a strong potential as a next-generation photovoltaic technology due to continuous efficiency improvements and the tunable properties, some important obstacles remain before industrialization is feasible. For example, the selection of low-cost or easy-to-prepare materials is essential for back-contacts and hole-transporting layers. Likewise, the choice of conductive substrates, the identification of large-scale manufacturing techniques as well as the development of appropriate aging protocols are key objectives currently under investigation by the international scientific community. This Review analyses the above aspects and highlights the critical points that currently limit the industrial production of PSCs and what strategies are emerging to make these solar cells the leaders in the photovoltaic field.

“…This reveals the attainment of amorphous phase which is generally in line with the increase of carrier ions concentration. Amorphous phase accompanied by charge carrier concentration usually enhance ionic diffusivity in polymer electrolyte system [10]. The maximum amorphous nature is presented by 0.4 wt% LiCF 3 SO 3 content with i-carrageenan which may experience high ionic diffusivity and yield maximum ionic conductivity.…”

In the present work, iota-carrageenan (i-carrageenan) biopolymer derived from edible seaweed has been chosen as the host polymer material for battery electrolyte. Ionic salt of lithium trifluoromethanesulfonate (LiCF 3 SO 3 ) commonly known as lithium triflate has been added with the host polymer as a source of charge carriers. The polymer membranes of 1.0 g i-carrageenan with LiCF 3 SO 3 of various compositions (0.1 wt% to 0.5 wt%) have been prepared by solution casting technique. X-ray diffraction (XRD) results indicate the enhancement in amorphous nature of polymer membranes due to the addition of LiCF 3 SO 3 . Complex formation between the salt and polymer has been studied by Fourier Transform Infrared (FTIR) spectroscopy. The high ionic conductivity of 1.27×10 −3 S cm −1 at room temperature is achieved with the combination of 1.0 g i-carrageenan : 0.4 wt% LiCF 3 SO 3 by AC impedance analysis. Total ion transference number estimated for the highest conducting sample is 0.95 by Wagner's DC polarization method and electrochemical stability of the same is 3.52 V by Linear Sweep Voltammetry (LSV) measurement. Lithium ion conducting battery has been fabricated using the highest conducting polymer membrane. Its open circuit voltage is measured as 1.70 V and its performance is studied.
