“…The electrolyte needs to have high ionic conductivity and thermal stability. Li et al [24] asserted that the two main processes that lower the cell efficiency are the undesired recombination of the excited electron with triiodide ion, as well as the slow rate in the regeneration of dye particles due to low diffusion coefficient of the redox couple and low ionic conductivity. Both of these issues stem from the electrolyte components.…”

“…Due to this, high ions diffusion of the redox couple is desirable. Although some had suggested that the presence of bulky cation from ILs can help in reducing the recombination process, but the improvement of V oc was rather mediocre and could not drastically boost up the cell efficiency [23,24]. As a result, up until now, the DSSCs performances that used organic solvents in the electrolyte remain unbeatable.…”

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.

“…This is most probably the reason for the increase in photovoltaic efficiencies of the DSSCs. This increment can be recognized due to the larger number of the diffusion coefficient of triiodide rendering the dye molecule to be able to regenerate more easily resulting in lower recombination rate which leads to increase of J sc 57 58 59 . Normally, the charge transport mechanism in the polymer electrolyte of the DSSCs can be interpreted as Grotthus mechanism which is also known as the electron hopping and ion exchange 60 61 62 .…”

In this study, dye-sensitized solar cells (DSSCs) has been assembled with poly(1-vinylpyrrolidone-co-vinyl acetate) (P(VP-co-VAc)) gel polymer electrolytes (GPEs) which have been incorporated with binary salt and an ionic liquid. The potential of this combination was studied and reported. The binary salt system GPEs was having ionic conductivity and power conversion efficiency (PCE) that could reach up to 1.90 × 10−3 S cm−1 and 5.53%, respectively. Interestingly, upon the addition of the ionic liquid, MPII into the binary salt system the ionic conductivity and PCE had risen steadily up to 4.09 × 10−3 S cm−1 and 5.94%, respectively. In order to know more about this phenomenon, the electrochemical impedance studies (EIS) of the GPE samples have been done and reported. Fourier transform infrared studies (FTIR) and thermogravimetric analysis (TGA) have also been studied to understand more on the structural and thermal properties of the GPEs. The Nyquist plot and Bodes plot studies have been done in order to understand the electrochemical properties of the GPE based DSSCs and Tafel polarization studies were done to determine the electrocatalytic activity of the GPE samples.
