“…Furthermore, the decrease in the thermal stability was also due to the conversion of GPE samples from crystalline to amorphous phase transition of the synthesized electrolytes with increasing salt concentration. Therefore, it was clear that the effect of the salt transformed the crystalline electrolytes to an amorphous one, as shown by the FTIR and XRD spectra discussed in the previous section . With respect to the second step of degradation, TGA suggested that N0 was more thermally stable than the other GPE samples.…”

New gel polymer electrolytes (GPEs) were prepared via the blending of a polyacrylonitrile polymer and a poly(1‐vinyl pyrrolidone‐co‐vinyl acetate) copolymer. The sodium iodide (NaI) salt concentration was varied for each GPE sample. From ionic conductivity (σ) studies, we observed that the sample with a 40 wt % NaI salt content (N40) showed the highest σ of 3.54 × 10−3 ± 0.05 S/cm at room temperature, and all of the GPE samples obeyed Arrhenius behavior. The dielectric properties of the GPE samples were also analyzed to study the electrical polarization of the materials. The developed GPE samples were also characterized with X‐ray diffraction and Fourier transform infrared spectroscopy. We also then used the developed GPE samples for the fabrication of dye‐sensitized solar cells by sandwiching them between a photoanode and Pt counter electrode for photovoltaic studies. The highest photovoltaic performance was achieved by N40, with an efficiency of 3.04%. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47810.

This research was conducted to extract sodium alginate from Turbinaria conoides and its structural property as biopolymer electrolyte. The existence of brown seaweed (Turbinaria conoides) is abundant in Bangka Belitung Islands. The main content of brown seaweed is alginate that it can be used as biopolymer electrolyte. Sodium alginate extraction process in Turbinaria conoides was carried out at 60 o C with 5% Na2CO3 and the yield of sodium alginate was 13%. Sodium alginate is successfully extracted in Turbinaria conoides. Sodium alginate was characterized using FTIR. The results showed that sodium alginate extract had similar spectrum and same main fuctional group with commercial sodium alginate. Characterization structural property of biopolymer electrolyte by FTIR-ATR. the increasing NaI percentage in sodium alginate made shift of peak toward higher wavenumber. These shifting indicated increasing of interaction between NaI with polymer chain in alginate and degree of salt dispersion in polymer

“…DSSCs were fabricated, and the highest energy conversion efficiency (2.09%) was attained in the presence of 20 wt% of MPII in the starch matrix. In a subsequent study, the same group investigated biodegradable rice starch-based polymer electrolytes in the presence of different iodide salts (34). LiI, NH 4 I, and NaI were used, and the polymer electrolyte system containing sodium iodide shows the highest ionic conductivity upon addition of 45 wt% NaI; the complexation of the latter with the biopolymer was demonstrated by Fourier transform infrared (FTIR) spectroscopy.…”

Glass GlassHowever, despite the record efficiency of 14.3% and the recent large-scale industrial production, DSSCs still depend on oil-derived electrolytes and nanostructured electrodes designed by expensive templating agents.This trend is changing, and in recent years the scientific community has started to propose natural polymers as substitutes for the more expensive and oil-derived materials. In this article, we present some electrolytes and electrodes developed with these new materials and demonstrate how the DSSC device is gradually approaching the highly cited and mentioned artificial leaf.
