“…showed that the presence of a 1-methyl-3-hexylimidazolium iodide (MHII) ionic liquid in cyanoethylated hydroxypropyl cellulose (CN-HPC) reduced the charge recombination between redox couple species and the oxide semiconductor surface due to the bulky structure of MHII compared to I − [ 118 ]. The addition of Co 3 O 4 , NiO, and TiO 2 nanoparticles can also improve conductivity [ 119 ]. The presence of cross-linking networks between nanoparticles and polymers facilitates ion transport within the polymer matrix.…”

“…One of the studies on this topic was conducted by Shih et al., where the interfacial interaction of iodide as a redox couple and agarose as a polymer matrix was investigated. The XPS study confirmed the formation of polyiodide in the electrolyte, which benefited the charge transfer channels after adding TiO 2 nanoparticles into the electrolyte gel system [ 119 ].…”

“…Also, many experiments have been performed to investigate the effects for the suppression of charge recombination and development in the photovoltaic performance [46]. Although extraordinary progress has been made in the direction of suited stable performance, however, there are many bottlenecks for the stability of these devices at a large-scale production [47]. Even if, the particularly efficient DSSC use liquid electrolyte it raises foremost technological challenges for huge scale commercial applications due to its volatilization, leakage of solvent, corrosion of electrode and airtight sealing of the cell.…”

“…This is because the polymer matrix which could efficaciously lure the liquid solvent to prevent evaporation and, in the meantime, provide channels to increase the rate of redox couples. These electrolytes based on permeable polymer membranes are relatively favoured, that could trap a large amount of liquid electrolyte and have good contact and high conductivity with the electrodes than the solid-state [47]. Kim et al, are the pioneer of synthesizing the PMMA copolymer-based porous membrane in the polymer-based electrolyte in DSSC and attained an efficiency of 2.4% [54].…”

The global increase in energy demand has resulted in the depletion of non-renewable resources and caused environmental degradation. Consequently, emerging renewable technologies are a potential solution to fulfil energy demand and mitigate the effect of global warming. Low-cost solar energy harvesting technologies are most feasible technologies. Various solar cells technologies have been developed with improved overall performance and conversion efficiency. However, due to low cost and a wide range of applications, dye-sensitized solar cells (DSSCs) have been immensely focused on one of the most promising third-generation solar cells. The highest conversion efficiency of DSSC achieved after three decades of research is more than 14%, but the commercialization of this technology is still a challenge. In this review paper, an attempt has been made to present the comparison of different articles published, that gives the in-depth study of recent developments in various types of DSSCs based on architectural assembly and physical appearance. An overview of the limitations and challenges with their possible improvement strategies have also been discussed. This review paper concludes that appropriate selection of electrolytes dramatically affects the performance of DSSC, and quasi-solid-state electrolyte proves to be a better option. Besides, it also concludes that tandem structures are widely agreed with the approach to expand light utilization spectrum for an overall increase in its performance. However, still, the research is required, which could efficiently widen the applications of the DSSCs.

“…DSSCs can be prepared easily at a low cost [1]. Among the electrolytes used in DSSCs, liquid-state electrolytes have been studied extensively due to their high efficiency (~12%) [2][3][4][5][6][7][8][9][10]. However, liquid-state electrolytes exhibit instability because of leakage and evaporation, and hence find limited DSSC applications.…”

Solar energy conversion devices composed of highly crystalline gel polymers with disk-WO3 nanostructure and plate-WO3 microstructures (D-WO3 and P-WO3, respectively) exhibited higher power conversion efficiency than those with a gel electrolyte. In this study, D-WO3 and P-WO3 were prepared using a hydrothermal process and their structural and morphological features were investigated for application in solar energy conversion devices. The P-WO3 solid-state electrolyte significantly enhanced the cell performance owing to its charge transportation and light-scattering characteristics. The P-WO3 solid-state electrolyte showed a power conversion efficiency of 6.3%, which is higher than those of the gel (4.2%) and D-WO3 solid-state (5.5%) electrolytes. The electro-chemical impedance spectroscopy (EIS), intensity-modulated voltage spectroscopy (IMVS), diffuse reflectance, and incident photon-to-current conversion efficiency (IPCE) analysis results showed that the P-WO3 solid-state electrolyte showed improved charge transportation and light scattering, and hence enhanced the cell performance.
