“…As for D149 dye, the peak at 1128 cm −1 corresponds to a C-O bond. The peaks at 1240, 1547, and 1697 cm −1 can be classified with N-C=, C=C, and C=O bonds, respectively [53]. The D149/pCN pattern is highly similar to the pCN pattern.…”

Protonated g-C3N4 (pCN) formed by treating bulk g-C3N4 with an aqueous HCl solution was modified with D149 dye, i.e., 5-[[4[4-(2,2-diphenylethenyl) phenyl]-1,2,3,3a,4,8b-hexahydrocyclopent[b]indol-7-yl] methylene]-2-(3-ethyl-4-oxo-2-thioxo-5-thiazolidinylidene)-4-oxo-thiazolidin-2-ylidenerhodanine, for photocatalytic water splitting (using Pt as a co-catalyst). The D149/pCN-Pt composite showed a much higher rate (2138.2 µmol·h−1·g−1) of H2 production than pCN-Pt (657.0 µmol·h−1·g−1). Through relevant characterization, the significantly high activity of D149/pCN-Pt was linked to improved absorption of visible light, accelerated electron transfer, and more efficient separation of charge carriers. The presence of both D149 and Pt was found to be important for these factors. A mechanism was proposed.

“…The unique properties of zinc tin oxide (Zn 2 SnO 4 ), including wide band gap (3.6 eV), high electron mobility (10-15 cm 2 V − 1 s − 1 ), superior electrical conductivity (~10 4 Scm − 1 ), attractive optical features, and low visible absorption confirm the known significance of the material [1][2][3]. Under these circumstances, the compound has been used in several widespread applications involving photocatalysts [4], gas sensors [5], DSSCs [2], and anodes for lithium-ion batteries [6].…”

“…Al‐Attafi et al synthesized Zn 2 SnO 4 cubic aggregates by solvothermal method and employed as a photoanode material along with D149‐ and N719‐based dyes in DSSC. [ 95 ] When compared to TiO 2 , Zn 2 SnO 4 ‐based photoanodes adsorb higher amount of dye. This is due to the high isoelectric point offered by Zn 2 SnO 4.…”

The quality of human life in the modern era seems to be highly reliable on the technology advancements and energy consumption. [1] Globally, around 85% of the energy depends on nonrenewable sources which may extinct within next few years. [2] In this context, solar cells in specifically dye-sensitized solar cells (DSSCs), which come under thin-filmbased third-generation solar cells, are considered to play a vital role of fulfilling the future energy needs by means of its proficient energy conversion potential, in addition to its lightweight, low-cost, reliable efficiency, multicolor options, and feasible for both indoor and outdoor applications. It is one of the most promising energy conversion devices from its technological discovery of early 1990s by Brain O'Regan and Michael Gratzel [3,4] In general, the working of DSSC depends on five major components, namely, 1) substrate, 2) semiconductor nanolayer, 3) the sensitizer, 3) redox electrolyte, and 5) counter electrode. The schematic representation of a typical DSSC with components is shown in Figure 1.Initially, the photosensitizer (dye) of the DSSC usually in its ground state and the illumination of light over the DSSC excite the ground state dye molecules from highest occupied molecular orbital (HOMO) level to the lowest unoccupied molecular orbital (LUMO) level (1), and then the electron from the LUMO level jumps over the conduction band of the semiconductor in 150 ps (2) and reaches the TCO. The holes produced during the excitation of dye molecules are scavenged by the electrons from the redox electrolyte (4) in 0.5 μs. The electrons reached the TCO then move to the cathode through the external circuit and power up the electrical load. Finally, the oxidized electrolyte gets reduced at the cathode (5) in 10 μs. [5,6] Besides these carrier-transport processes, some adverse reactions like nonradiative carrier-recombination paths will occur that desperately reduces the overall device performance. [7] Such unfavorable reactions are follows: nonradiative decay of immediate excitation of dye molecule to its ground state occurs in ns (6), plausible recombination of the electrons from the conduction band of the semiconductor material to the ground state of dye molecule occurs in ms (7), and to the electrolyte occurs in 100 ns to 1 ms (8), respectively. [8] The substrate for the photoanode and cathode is the most important component. Apart from this metal foil or polymeric film, transparent conductive oxide (TCO)-coated transparent glass substrate, such as fluorine-doped tin dioxide (FTO) or
