“…Bulky substituents cause hindrance for the mobility of ionic couples. Khannam et al 180 reported 0.5% c-MWCNT anchored PVA/ PEG as nanocomposite gel polymer electrolyte for DSSCs. The c-MWCNT creates nanochannels to facilitate redox reaction and behaves as a bridge for the transport of charge species between photoanode and cathode.…”

Abundant solar energy has transformed the present solar photovoltaics owing to its rapid conversion into electrical energy without deteriorating ecosystem. Third generation (3G) energy conversion devices reveal utilization of photosensitizer, i.e., organic dye, quantum dots, and perovskite as functional absorbing materials to transform solar energy. Functional polymers are key ingredients (fuels) for the development of suitable redox potential and high temperature or humidity resistive charge transport medium. Electrolyte accelerates the photovoltaic reversible reaction (hole conduction) through exposure of a minimum energy barrier between the photoanode and cathode. Redox-active polymer enhances electrolyte uptake efficiency, ionic conductivity, and dimensional stability of solar device. Various electrolytes exhibit different functional activities due to their different redox energy. The functionalized polymer bears appropriate HOMO–LUMO energetics and low activation energy, which could adjust different photosensitizer with better compatibility. Therefore, the redox polymer percolates a redox couple at a photoexcited sensitizer through control of undesired reactions. It plays the important role of ion and electron transport mediator via expanding suitable interfacial energetics and band structure for photovoltaic reaction. The polymeric pendant groups (chemical environments) preserve electrolyte couples through reducing wettability and thus immobilize the active density of electrolyte anions for photovoltaic reactions. Thus, the polymer improves reversibility due to interfacial compatibility, electrolyte filtration effect, and synergistic stabilization. The present review focuses on polymer-derived functional electrolytes, photosensitizer–polymer interface, thermodynamic interactions, and power conversion efficiencies of 3G photovoltaic devices. Functional polymers open an avenue for the development of stable and efficient photovoltaic reactions at low cost based dyes, quantum dots, and perovskite-sensitized solar conversion systems.

“…[132] Polymer electrolytes were then considered for DSSC as they show high heat stability, superior ionic conductivity and eliminate solvent and sealing problems. [133][134][135] Ganesan et al [134] reported that fast segmental motion and Lewis acid contact between the cation and the donor molecule produce ionic conductivity. Compared to other electrolytes, Wang et al [128] found that gel polymer electrolytes (GPEs) have low vapor pressure, excellent electrode connection and higher ionic conductivity and are made by blocking liquefied solvents, organic solvents and inorganic salts.…”

The rapid growth of the population severely influences the supply of energy, accordingly ensuring clean energy has become a big challenge now and will be in the future. Fossil fuels have been satisfying the energy demand until now, but fossil fuels, being non‐renewable sources, will not be able to satisfy the energy demand in the future and will have a negative impact on the environment. Renewable energy sources have become the most demanding topic for researchers in this crisis. The solar cell, which is an abundant renewable energy resource, converts solar power into electrical energy without any environmental damage. Silicon solar cells have higher efficiency, but their high manufacturing cost, complicated procedures and environmental issues restrict their usage. Then dye‐sensitized solar cells (DSSCs) have been introduced as an alternative to silicon solar cells. In DSSC, both natural and synthetic dyes are used. Though synthetic dyes provide higher efficiency, they are environmentally harmful. Afterward, the concept of natural dye‐sensitized solar cells (NDSSC) have been materialized where only natural dyes are used. Researchers and environmentalists are looking for natural dyes as a replacement for synthetic dyes in recent times, as natural dyes are plentiful, can be collected naturally and have no environmental effects. Natural dyes in the form of anthocyanins, carotenoids, flavonoids, chlorophylls, tannins and betalains are extracted from various portions of plants that include leaves, roots, flowers, fruits, seeds, barks, etc. In this review, we investigate natural sources of dyes, natural sensitizers (dyes), shortcomings and remedies, improvements in efficiency and stability, developments, and commercialization. In addition, recent advances and the comparison of natural and synthetic dyes have been discussed in this review.
