“…Electrolyte with double salts like TPAI-KI, TBAI-KI, and TPAI-LiI showed improved J SC , V OC , and efficiency compared to electrolytes consisting of the same amount of TPAI, TBAI, KI, and LiI alone. However, conductivity decreased for the double salts system of KI compared to only the KI system because of low mobile ions. ,,,, In these electrolytes, because of bulky cation groups ion conductivity was mostly due to the iodide conductivity. Moreover, bulky cations enhanced V OC where smaller cations increased the J SC by increasing the electron injection rate.…”

“…Later, further selection of ion conductive polymer for the electrolyte preparation depends on the ability of the polymer to solvate the salts as well as glass transition temperature ( T g ) and crystalline nature of the polymer. − Polymers with high polar sites can form electrostatic bonds with the cations, which facilitates the solvation process. Furthermore, the polymer with low T g promotes the segmental motion and therefore increases the conduction.…”

“…For example, because of a lower lattice energy and larger cation size, NH 4 I and KI provide a higher number of available iodides in electrolytes compared to NaI and LiI. ,, Following the trend, quaternary ammonium salts such as TMAI, TPAI, and TBAI provide even a greater number of available free iodide ions compared to NH 4 I and KI (Figure ). However, the conductivity of these organic salts (TMAI, TPAI, and TBAI) is found to be lower as the bulky size of these cations prevents their mobility . Smaller cations (like Na + and Li + ) easily move through the segmental motion of polymer chain and are absorbed into the photoanode.…”

Continual escalation of our world population demands a vast and safe energy supply, the majority of which has been produced by fossil fuel sources. However, because of the huge energy demand, exponential depletion of these nonrenewable energy sources is inescapable and forthcoming in the coming century. Hence, utilization of renewable energy such as solar energy has gained attention because of its direct conversion of light energy into electrical power without any harmful environmental impacts. Solar energy has been harvested by different types of solar cells varying from inorganic to organic to the combination of both. Among them, the dye-sensitized solar cell (DSSC) with a biopolymer-based electrolyte has gained enormous consideration from researchers because of its sustainability, abundance of available raw material, low production cost, and easy production in addition to the low volatilization of electrolytes compared to liquid state electrolytes. This review aims to give an overview of the recent inputs in the development of biopolymer-based DSSCs. The performance of the biopolymers as electrolytes in DSSCs will be critically reviewed based on the physicochemical properties of the biopolymers. Key technical challenges and future research areas for the advancement of biopolymer-based DSSCs are also discussed.

Electrolytes have been considered a major component of DSSC and play a vital role in determining the ionic conductivity and efficiency of the cell. Emphasis was laid on the confirming the conductivity upon fabrication of an electrolyte using in situ gelation process from a newfangled combination of Triiodide (KI/I2/Glacial acetic acid/distilled water) and gel-based polymer electrolyte (Gelator: PMMA/THF/PC/EC) in the ratio 8:2. The electrolyte portion so framed generated a photo conversion efficiency of 11.32% and a fill factor of 0.439. The conductivity of the sample characterized by Scanning Electron Microscopy showed that the uniform tracks confirmed extreme ionic conductivity of the blend electrolyte which showed dependance on the layered movement of PMMA- co- THF- KI2/PC/EC based electrolyte system. Energy Dispersive x-ray Analysis (EDX) reports engrained the percentage weight proportions of conductive elements (C & O with a wt% of 65.48 and 30.18 in one spectrum and K & I with a wt% of 44.7 & 35.25 in another spectrum respectively). FTIR test analysis was performed to identify the functional groups of the PGE which identified the ionic conductivity of the sample, shown by the intensity of peak absorbance in the range 400–4000 cm−1. Further it was observed, the conductivity of the different concentrations of the liquid and gelator solution demonstrated an increase in exhibiting ionic conductivity and the same was depicted by the morphological studies that featured dark pores of the sample which were spread consistently indicating the amorphous nature of the material (at room temperature).

Amongst various sources of renewable energy, solar energy is becoming prime due to its advantages of cleanliness, abundance and low operating cost. Currently, amorphous silicon PV cells are most into commercialization but to contradict, they have a very high manufacturing cost and due to usage of hazardous materials, they lead to environmental degradation. Hence, they are less preferred now a days. To overcome these complications, Dye sensitized solar cells (DSSC) are replacing customary cells at a very fast rate. In this research, fabrication of DSSC was done based polymer gel electrolytes prepared by in situ gelation. The ionic properties of the polymer gel electrolyte were also observed with the help of various tests performed like FESEM, FTIR, XRD & TGA. FTIR & XRD affirmed the good electron emission characteristics of the polymer electrolyte. XRD & TGA give amorphous nature and weight loss indication near 360 °C for cell based on polymer electrolytes. The performance evaluation of hence fabricated DSSC’s was done in terms of calculating efficiency, fill factor, current density (short circuit) and photovoltage (open circuit). The efficiency of the cell was found out to be 11.32% and fill factor came out to be 0.439.
