“…As a result, the solar-to-electricity conversion efficiencies of DEII and HMII were 4.8% and 4.2%, respectively. In another study, several imidazolium-based ILs were synthesized and combined with 0.1 M LiI and 0.05 M I 2 in MPN to prepare the electrolyte component for DSSCs [33]. The use of MPN (with a high boiling point) was meant to increase the ionic properties of the electrolyte, which reflected an attempt to replace the can.…”

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.

“…Materials with transparent and conductive properties such as zinc oxide (ZnO), indium tin oxide (ITO) and fluorine doped tin oxide (FTO) are used in solar energy technologies, dye‐sensitive solar cells, quantum dyes sensitive solar cells, polymer solar cells and hybrid solar cells. So they play a very important role in these technologies . Today indium (In) doped tin oxide, also known as ITO, is widely used as TCO in industries.…”

In this work, aluminum-doped ZnO (AZO, Al:ZnO) nanocomposite materials were prepared by a simple hydrothermal method using the microwave oven. Zinc oxide nanostructures were doped with aluminum in different dopant concentrations (0.5%, 1.0%, 1.5% and 2.0%). AZO materials were analyzed using XRD, SEM and EDX measurements. Also dye-sensitized solar cell (DSSC) performances of AZOs were investigated. The scanning electron microscopy (SEM) analysis confirms that the synthesized AZO nanomaterials were nanorods and nanoplates in shape and have 200 nm to 974 nm sizes in length and 116.1-269.5 nm in diameters (shown Figure 4-5). Dye-sensitized solar cell efficiencies are higher in 0.5% and 1% AZO nanorod materials. We have found the maximum efficiency as 1.94% for 1% doped AZO nanorod materials.

“…Room temperature ionic liquids (RTILs) are well‐known as designer entirely ionic materials and have drawn a considerable scientific interest due to their wide applications in various fields starting from green solvent for organic chemistry to electrolytes in alternative energy generation/storage devices such as lithium batteries, fuel cells, and solar cells . A broad range of applications of ILs is expected due to their low flammability, negligible vapor pressure, unusual catalytic properties, high ionic conductivity and electrochemical stability .…”

In present work, role of weak interactions on physical property of newly synthesized 2,4‐Dinitrophenolate (DNP) anion‐based imidazolium room temperature ionic liquids (RTILs) has been investigated for understanding effect of small structural change in anion. Aromatic and aliphatic H‐bonding interaction do not play significant role on physical properties of these RTILs. But weak π‐π stacking interaction plays an important role to determine the physical properties of these RTILs. The DNP anion shows unique characteristic intramolecular charge transfer (ICT) process due to presence of its quinoid structure in solution. Quinoid structure of DNP anion in these RTILs does not allow to form strong intermolecular ion‐pair cluster through π‐π stacking interaction. As intermolecular interactions are very less, DNP based RTILs are liquids at room temperature. Tuning electronic and physical properties of these yellow coloured DNP based RTILs are raised only from DNP anion.
