“…On the basis of Figure , there are three semicircles recorded in the impedance plots. Those three semicircles had also been reported in refs ,− . The first semicircle in the high frequency range describes the resistance of charge transfer ( R t ) at the interface between the electrolyte and counter electrode .…”

“…An IL is an ionic compound that exists as a liquid below 100 °C and has poor cation and anion coordination. , Other than that, IL has a low melting temperature, nonflammability, negligible vapor pressure, high thermal stability (473–573 K), wide potential windows, and high electrical conductivity. − IL can act as a plasticizer as well as provide additional charge carriers in the GPEs (gel polymer electrolytes). Examples of IL are 1-methyl-3-propyl imidazolium (PMII), 1-methyl-3-propylimidazolium iodide (MPII), 1-hexyl-3-methylimidazolium iodide (HMII), , and 1-butyl-3-methylimidazolium iodide (BMII). , In this article, the BMII ionic liquid is chosen as it is reported to have a higher ionic conductivity at room temperature compared to HMII ionic liquid …”

“…Other than that, it can be clearly observed that J sc followed the same trend as ionic conductivity in Table . This can be attributed to the increase in the redox diffusion rate of charge transport in the electrolytes . Furthermore, the higher mobility of charge carriers in the C3 electrolyte as shown in Figure helps the electron transfer from the counter electrode to the ionized dye occur rapidly.…”

Improvement of the electrolyte ionic conductivity in DSSCs application is important as it contributes higher solar conversion efficiency. In this article, the polyurethane acrylate (PUA) gel polymer electrolyte (GPE) system was further improved with the addition of an ionic liquid in terms of ionic conductivity and also photovoltaic performance. The PUA GPE system enhanced with 6 wt % of 1-butyl-3-methylimidazolium iodide (BMII) ionic liquid was found to produce the highest improvement (ionic conductivity) compared to the different content of BMII. Ionic conductivity of (4.17 ± 0.01) × 10–4 S cm–1 was observed at room temperature with the addition of 6 wt % BMII in the GPE system. Moreover, the DSSC utilizing the GPE with 6 wt % BMII produces the highest solar conversion efficiency of (5.72 ± 0.14)% corresponding with the J sc of (23.03 ± 0.2) mA cm–2 and V oc of (0.54 ± 0.01) V.

“…In the electrolyte system containing big cations such as Pr 4 N + (4.59 Å) and BMI + (3.85 Å), 40 lowering of Fermi level of TiO 2 is less as the big cations do not absorb easily to the TiO 2 surface. Thus, the values of V oc obtained for electrolytes with big cations are generally in the range of 0.6–0.7 V. 41 –44…”

Polymer electrolytes based on the blends of poly(methyl acrylate) (PMA) and poly(vinyl acetate) (PVAc) were prepared using tetrapropylammonium iodide (TPAI) salt and 1-butyl-3-methylimidazolium iodide (BMII) ionic liquid. Single transition between the glass transition temperatures of the constituents indicates the miscibility of PMA and PVAc over the entire composition range. The presence of TPAI and BMII does not affect the miscibility of PMA and PVAc. The complexation in the PMA/PVAc-TPAI-BMII is supported by the differential scanning calorimetry and Fourier transform infrared spectroscopic studies. Conductivity increases by two order of magnitudes with the incorporation of 5 wt% of BMII. Conductivity increment is due to the extra charge carriers provided by BMII. Electrolyte films were sandwiched between titanium dioxide photoanode and platinum counter electrode for dye-sensitized solar cells (DSSCs) assembly. The addition of BMII increases the efficiency of DSSC from 2.79% to 4.62%.

“…However, conventional liquid electrolytes in DSSCs present drawbacks that mostly stem from solvent leakage or evaporation issues and lower the stability of devices. Therefore, many studies have focused on replacing the conventional liquid electrolytes used in DSSCs with ionic liquids, hole-transport materials, and quasi-solid-state electrolytes in order to reduce the risk of leakage and environmental hazards [ 19 , 20 , 21 ]. Among them, the quasi-solid-state electrolytes based on low-molecular-weight polymers and inorganic nanomaterials exhibit ionic conductivities close to those of a conventional liquid electrolyte but maintain their quasi-solid-state electrolyte structures, thereby reducing solvent leakage and evaporation problems and enhancing mechanical properties.…”

Quasi-Solid-State SiO2 Electrolyte Prepared from Raw Fly Ash for Enhanced Solar Energy Conversion

et al. 2022

Quasi-solid-state electrolytes in dye-sensitized solar cells (DSSCs) prevent solvent leakage or evaporation and stability issues that conventional electrolytes cannot; however, there are no known reports that use such an electrolyte based on fly ash SiO2 (FA_SiO2) from raw fly ash (RFA) for solar energy conversion applications. Hence, in this study, quasi-solid-state electrolytes based on FA_SiO2 are prepared from RFA and poly(ethylene glycol) (PEG) for solar energy conversion. The structural, morphological, chemical, and electrochemical properties of the DSSCs using this electrolyte are characterized by X-ray diffraction (XRD), high-resolution field-emission scanning electron microscopy (HR-FESEM), X-ray fluorescence (XRF), diffuse reflectance spectroscopy, electrochemical impedance spectroscopy (EIS), and incident photon-to-electron conversion efficiency (IPCE) measurements. The DSSCs based on the quasi-solid-state electrolyte (SiO2) show a cell efficiency of 5.5%, which is higher than those of nanogel electrolytes (5.0%). The enhancement of the cell efficiency is primarily due to the increase in the open circuit voltage and fill factor caused by the reduced electron recombination and improved electron transfer properties. The findings confirm that the RFA-based quasi-solid-state (SiO2) electrolyte is an alternative to conventional liquid-state electrolytes, making this approach among the most promising strategies for use in low-cost solar energy conversion devices.
