“…Due to the disadvantages of nonrenewable energy, the search for renewable energy sources has become apparent among researchers and manufacturers. One of the renewable energy sources to produce from renewable resource-based jatropha oil (nonedible plant oil) is one of the suitable candidates for the synthesis of a sustainable polymer electrolyte. − …”

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.

“…Mahmood et al in 2015 [17] shed some light on how far the progress of quasi-solid state electrolytes DSSCs (qs-DSSCs) with extra attention given on how this type of electrolyte was beneficial to obtain DSSCs with better thermal stability and cell efficiency. A review by Yusuf et al [18] in 2017 was focused on how ILs have indeed enhanced the polymer electrolytes and how the incorporation of ILs have affected the performance of various electrochemical devices, such as batteries, supercapacitors, fuel cells, and DSSCs. Quite different from other reviews, Muhammad [19] concentrated on how the physical properties of quasi solid-state polymer electrolytes were characterized.…”

Exploration of renewable energy, such as solar energy, is imminent not only to cater to the escalating energy demand but also to address the uprising environmental issues due to heavy usage of non-renewable fossil fuel. The dye-sensitized solar cells (DSSCs) which are considered as the third-generation solar cells, have a huge potential to be commercialized due to their low cost, simplicity in fabrication, and promising photon-to-electrical energy conversion efficiency. Nevertheless, a high cell efficiency can only be achieved when an organic solvent is incorporated into the formulation of the electrolyte, which is prone to evaporation and leakage. As a result, DSSCs become unsuitable for long-run usage due to thermal instability in the electrolyte. The early intention of incorporating ionic liquids (ILs) into the electrolyte was to curb the abovementioned problem and to enable the DSSCs to function as a sustainable energy device. As such, this article briefly reviews how ILs have been incorporated into the electrolyte formulation and the extent of how the ILs can affect the cell efficiency in various electrolyte states. The role of the ILs in a range of electrolytes is also highlighted. This sheds light on the true purpose of introducing ILs into DSSC electrolyte, which is to enhance the ionicity of the electrolyte.

“…The roles of ionic liquid as conductivity enhancer include plasticization effect and charge carrier provider. 5,34 –37 However, the present study suggests that conductivity enhancement cannot be attributed to the plasticization effect of BMII, as T g is observed to increase upon the incorporation of BMII (cf. Figure 3).…”

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%.
