“…The polarization curve for single IL and all the binary IL based GPE samples were portrayed in Figure 1. From the graphs, the transference number of charge carrier can be determined from the steady‐state current ( I SS ) and the initial current ( I i ) ratio as shown in Equations () and () 21 ;

t_{e} = I_{SS} / I_{i}

t_{ion} = ((), I_{i} - I_{ss}) / I_{i} = 1 - t_{e}

where t ion represents the transference number of ions. The values of t e and t ion for single IL and all the binary IL based GPE samples were presented in Table 2.…”

In this work, novel redox electrolytes based on poly (ethylene oxide) (PEO) were prepared using binary ionic liquid 1‐methyl‐3‐propylimidazolium iodide (MPII) with 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) or 1‐butyl‐3‐methylimidazolium tetrafluoroborate (BMIMBF4) to reduce the high viscosity of MPII. The addition of low viscosity ionic liquids is to overcome the low mass transportation of redox mediator faced by the single ionic liquid. Therefore, different ratios of ionic liquids were added, and their effect on the electrical properties of the ionic liquid‐based gel polymer electrolytes (GPE) was observed. It was confirmed that all the system dominant by ions rather than electron. The binary ionic liquid system containing 37.5 wt.% of BMIMBF4 showed the highest ionic conductivity of 24.2 mS cm−1. Fourier‐transform infrared and X‐ray diffraction studies confirmed that complexation occurred between all materials. The combination of two alkyl side chain length has enhanced the efficiency of the DSSC with short‐circuit current density (JSC) of 26.81 mA cm−1, open‐circuit voltage (VOC) of 0.67 V, fill factor of 44.5% and photovoltaic conversion efficiency (η) of 7.8%. This work has provided valuable insight for further stability of binary ionic liquid‐based GPE compared to single ionic liquid electrolytes.

“…Some research activities aim to improve GPEs. Saidi et al [ 67 ] used a different concentration of 4-tert-butyl-pyridine (TBP) in a gel polymer (GP) for the performance improvement of DSSC and found that the quasi-fermi level of the TiO 2 photo-anode shifted towards higher potential. The presence of 7% of TBP by weight increased V OC by 21.31%.…”

Significant growth has been observed in the research domain of dye-sensitized solar cells (DSSCs) due to the simplicity in its manufacturing, low cost, and high-energy conversion efficiency. The electrolytes in DSSCs play an important role in determining the photovoltaic performance of the DSSCs, e.g., volatile liquid electrolytes suffer from poor thermal stability. Although low volatility liquid electrolytes and solid polymer electrolytes circumvent the stability issues, gel polymer electrolytes with high ionic conductivity and enduring stability are stimulating substitutes for liquid electrolytes in DSSC. In this review paper, the advantages of gel polymer electrolytes (GPEs) are discussed along with other types of electrolytes, e.g., solid polymer electrolytes and p-type semiconductor-based electrolytes. The benefits of incorporating ionic liquids into GPEs are highlighted in conjunction with the factors that affect the ionic conductivity of GPEs. The strategies on the improvement of the properties of DSSCs based on GPE are also presented.

“…The electrolyte then transports the electrons back to the molecular dye and regenerate the oxidized dye. 17 It is noteworthy to state that every dye conducts but at different degree of absorption. However, it will be interesting to study the degree of conductivity of our novel dyes in respect to solar voltaic cells to ascertain their viability to such application.…”
