“…This reduced interaction subsequently minimized the charge recombination between the counter electrode and oxidized electrolyte ions. In another study, dyes based on dithiafulvenyltriphenylamine bearing two alkyl chains of various lengths were synthesized by Wan et al 9 With the increase in alkyl chain length from methyl (WD9) to hexyl (WD12) to decyl (WD13), the power conversion efficiency of DSSCs increased linearly as 3.18, 4.29, and 4.62%, respectively. Lee et al 5 reported increased photovoltaic parameters by the increase of N-alkyl chain length bridged between two phenothiazine units in dyes up to −C 8 H 17 .…”

“…Furthermore, the incremental adjustment of optical and electrochemical properties through structural modifications in organic dyes has spurred a deeper exploration by scientists. Compounds derived from coumarin, indoline, hemicyanin, carbazole, triphenylamine, tetrahydroquinoline, porphyrin, and phenothiazine units have been synthesized for their potential application in DSSCs. − Among these compounds, phenothiazine stands out because of its distinct structural attributes and has demonstrated success as an electron donor in DSSCs. Phenothiazine (PTZ) features a heterotricyclic scaffold with two electron-rich sulfur and nitrogen heteroatoms, making it an effective electron donor compared to other organic counterparts.…”

The impact of the alkyl chain on the nitrogen atom�N-ethyl, N-butyl, N-octyl, and N-dodecyl�in phenothiazines with bis-2-cyanoacrylic acid units on the optical and electrochemical behavior and finally photovoltaic response of DSSCs sensitized with such dyes was investigated. Such compounds as alternatives to ruthenium-based dyes were evaluated. The optical properties of the phenothiazine derivatives were studied by UV−vis and photoluminescence measurements in various solutions. Additionally, electronic absorption spectra of dyes anchored to TiO 2 were registered. Electrochemical properties were studied by using cyclic and differential pulse voltammetry. Experimental data and the adsorption energies of dyes@TiO 2 were supported by DFT and TD-DFT calculations. DSSCs consisting of a TiO 2 anode sensitized with prepared dyes, I − /I 3 − electrolyte, and Pt/FTO counter electrode were fabricated. The idea of dye cocktail utilization was also developed. The prepared solar cells were characterized via current−voltage, transient absorption, and electrochemical impedance spectroscopy measurements. Transient absorption spectroscopy revealed a positive effect of the alkyl chain length and cocktail dye configuration on the efficiency of the fast electron transfer processes.

“…Porphyrin derivatives are an effective alternative to ruthenium sensitizers, as they exhibit a series of photophysical properties that are appropriate for DSSC, such as broad absorption in the visible region, and favorable cell kinetics for electron injection and charge recombination [ 20 ]. That explains why porphyrins have been so extensively investigated as dyes in DSSC during the last decade [ 11 , 13 , 20 , 21 , 22 ]. In 2014, the performance of porphyrin-based DSSC (PCE = 13%) [ 23 ] exceeded that of the ruthenium-based DSSC.…”

New β-amino-substituted porphyrin derivatives bearing carboxy groups were synthesized and their performance as sensitizers in dye-sensitized solar cells (DSSC) was evaluated. The new compounds were obtained in good yields (63–74%) through nucleophilic aromatic substitution reactions with 3-sulfanyl- and 4-sulfanylbenzoic acids. Although the electrochemical studies indicated suitable HOMO and LUMO energy levels for use in DSSC, the devices fabricated with these compounds revealed a low power conversion efficiency (PCE) that is primarily due to the low open-circuit voltage (Voc) and short-circuit current density (Jsc) values.

“…Photogenerated electrons and holes emanate from semiconductors and participate in oxidation and reduction, respectively on irradiation of light [7] . As an outcome, photocatalysis enhances redox processes such as water oxidation, CO 2 reduction, H 2 evolution, Dye sensitized solar cell, N 2 fixation, biomass conversion and pollutant degradation [8–25] . With an abundance of active groups (⋅OH, O 2 − ⋅) that are produced by the photocatalysts underneath sunlight, visible light, or ultraviolet light, subsequently the organic pollutants are successfully undermined.…”

In latest events, water pollution has posed an immense threat, and its sustainable treatment is a topic of concern. Among myriad of water treatment, research community has lensed towards sustainable heterogeneous photocatalysis especially, inorganic semiconductors. Bismuth tungstate a pristine Aurivillius compound with unique crystal structure, exceptional photochemical stability, and strong redox abilities but minimum visible light absorption and quick carrier recombination are its caveats, these caveats are circumvented by synthesizing BiOX (X=F, Cl, Br and I) composites with surface modifiers, doping with hetero atoms (metals and non‐metals), construction of the heterojunction and amalgamation of carbon materials. The heart of this review is strategic engineering of flower‐like morphology photocatalyst synthesis and optical properties, it also discusses the charge transfer kinetics, photocatalytic performance, and durability. The flower‐like morphology highlighted in this review is due to its ability to harvest light, providing larger specific surface area which introduces more active sites and efficient excitons generation. The comprehensive tabulated data in this review will help the actively engaged research community in Bismuth heterogenous photocatalysis. It also sheds light on the future view of environmental remediation via photocatalytic developments.
