“…[127] In all the quasi-solid systems proposed right now, a liquid is still present and some criticism versus the unavoidable liquid exudation from the cells upon years is forcing a part of the scientific community to identify truly solid-state electrolytes. [69,128,129] The same criticism has been raised in the lithium batteries field. [130][131][132][133][134][135] Anyway, a first class of liquid-free systems is that of polyelectrolytes, [136] where charged anionic or cationic groups are chemically bonded to a macromolecular chain, leading the counterions to freely move between cell electrodes, undertaking charge carriers transportation.…”

“…[61][62][63][64][65] The scientific community has proposed numerous solutions to these purposes, which are summarized in various reviews present in the literature. [66][67][68][69][70] In this sector, poly(3,4-ethylenedioxythiophene) (PEDOT) plays an important role. [71] It was invented at the Bayer AG research laboratories around 40 years ago [72] and its excellent conductivity (300-500 S cm −1 ), high flexibility, excellent transparency in visible light, remarkable stability, and low cost (even if an accurate and comparative LCA is still missing) make it among the most desired polymeric organic conductors of interest for electronic, antistatic and optoelectronic applications.…”

Dye-sensitized solar cells (DSSCs) have become a strong reality in the field of hybrid photovoltaics. Their ability to operate in diffused light conditions and the possibility of fabrication of modules bearing different colors make these cells attractive for different applications, for example, wearable electronics, building integration, etc. This review focuses on one of the compounds rather often studied for DSSCs, namely, poly(3,4-ethylenedioxythiophene) (PEDOT). It has been introduced both as a substitute for liquid electrolytes, in order to facilitate cells fabrication and increase their durability, and as an alternative to platinum for counter electrodes. The literature counts many studies on PEDOT and this manuscript collects them following a classification criterion based on applications, functionalization/doping strategies, and deposition methods. In addition to comparing the performance obtained for PEDOT-based systems with those of traditional cells (i.e., assembled with liquid iodine-based electrolytes and platinum cathodes), the manuscript also offers a brief analysis of costs and sustainability aspects, built up on experimental data found in the literature; this latter is expected to constitute a precious resource to catalyze the attention of the scientific community on relevant and preliminary aspects when figuring out the industrial scalability of newly proposed cell components.

“…Since, DSSCs are affected by evaporation and leakage found in liquid electrolyte. To overcome these drawbacks, novel solid or quasisolid state electrolytes, such as hole transportation materials, p-type semiconductors, and polymer-based gel electrolytes, have been developed as potential alternatives to volatile liquid electrolytes [59].…”

Production of green energy by using environment friendly and cost-effective components is attracting the attention of the research world and is found to be a promising approach to replace nonrenewable energy sources. Among the green energy sources, dye-sensitized solar cells (DSSCs) are found to be the most alternative way to reduce the energy demand crises in current situation. The efficiency of DSSCs is dependent on numerous factors such as the solvent used for dye extraction, anode and cathode electrodes, and the thickness of the film, electrolyte, dye, and nature of FTO/ITO glasses. The efficiency of synthetic dye-based DSSCs is enhanced as compared to their counterparts. However, it has been found that many of the synthetic sensitizers used in DSSCs are toxic, and some of them are found to cause carcinogenicity in nature by forming a complex agent. Instead, using various parts of green plants such as leaves, roots, steam, peel waste, flowers, various spices, and mixtures of them would be a highly environmentally friendly and good efficient. The present review focuses on and summarizes the efficiency affecting factors, the various categories of natural sensitizers, and solvent effects. Furthermore, the review work assesses the experimentally and computationally obtained values and their progress in development.

Structural, Thermal, and Electrical Properties of Poly(Ethylene Oxide)—Tetramethyl Succinonitrile Blend for Redox Mediators

et al. 2022

An all-solid–state dye-sensitized solar cell is one of the non-fossil fuel-based electrochemical devices for electricity generation in a high-temperature region. This device utilizes a redox mediator, which is a fast ion-conducting solid polymer electrolyte (SPE). The SPE makes the device economical, thinner, and safer in high-temperature regions. The SPE generally has a form of matrix−plasticizer−redox salts. Succinonitrile (SN) is generally employed as a plasticizer for reducing the crystallinity of poly(ethylene oxide), abbreviated as PEO, a common polymeric matrix. In the present paper, the structural and thermal properties of tetramethyl succinonitrile (TMSN) were compared with SN for its application as a solid plasticizer. TMSN and SN both are plastic crystals. TMSN has four methyl groups by replacing the hydrogen of the SN, resulting in higher molecular weight, solid–solid phase transition temperature, and melting temperature. We thoroughly studied the structural, thermal, and electrical properties of the [(1−x)PEO: xTMSN] blend for utilizing it as a matrix, where x = 0–0.25 in mole fraction. The FT-IR spectra and XRD patterns of the blends exhibited PEO-alike up to x = 0.15 mole and TMSN-alike for x > 0.15 mole. Differential scanning calorimetry revealed formation of a eutectic phase from x = 0.1 mole and phase separation from x = 0.15 mole. The blends with x = 0.1–0.15 mole had a low value of PEO crystallinity. Thermogravimetric analysis showed thermal stability of the blends up to 75 °C. The blends exhibited electrical conductivity, σ25°C more than 10−9 S cm−1, and Arrhenius behavior (activation energy, ~0.8 eV) in a temperature region, 25–50 °C.
