“…Wagalgave et al [ 41 ] have designed and synthesized two new diketopyrrolopyrrole (DPP)‐merocyanine (MC)‐based dyes termed as DPP1 and DPP2, used them in DSSCs application, and reported maximum efficiencies of 0.195% and 0.268%, respectively. Bayannavar et al [ 42 ] fabricated a device using the PDP rings as an anchoring group to explore the DSSCs performance with CdS NWs and achieved 3.21 times higher performance than the bare CdS NWs.…”

One dimensional (1‐D) CdS nanowires have been grown through a low temperature chemical route and have been sensitized with eosin‐G and ethyl eosin dyes to broaden the absorption spectrum of CdS and to enhance the photoelectrochemical (PEC) performance under illumination. The used method is advantageous due to its simplicity, low cost, scalability, and controllability. Interestingly, eosin‐G and ethyl eosin dyes yield nearly four‐ and six‐fold increase in device efficiency compared to bare CdS when tested in dye‐sensitized solar cell assembly. Structural, surface morphological, optical, and surface wettability studies have been formulated for CdS, whereas identification of materials along with PEC investigations were conducted through current density–voltage (J‐V), external quantum efficiency (EQE), characteristics under the illumination of 94.6 mW/cm2 (AM 1.5G), and electrochemical impedance spectroscopy (EIS).

“…In this direction, 1D nanowires have sparked tremendous interest in production of solar cells [26], which provide direct and effective paths for charge transport, decreased electron hopping and increased interfacial area. Regarding this, our team is researching CdS nanowires photoanodes to enhance the efficacy of the photovoltaic devices by employing various novel metal-free sensitizers and altering various anchoring groups [27][28][29].…”

Novel metal-free organic dyes (E)-2-cyano-3-(10-(prop-2-yn-1-yl)-10H-phenothiazin-3-yl)acrylic acid (PPC) and (E)-2-cyano-3-(10-((1-((7-methyl-2-oxo-2H-chromen-4-yl)methyl)-1H-1,2,3-triazol-4-yl)methyl)-4a,10a-dihydro-10H-phenothiazin-3-yl)acrylic acid (PCTC) was synthesized and then anchored to 1D cadmium sulfide nanowires (1D CdS NWs) for application in photoelectrochemical dye-sensitized solar cell (DSSC). The 1D CdS nanowires were interconnected into a nanonetwork using solution chemistry in a straightforward and efficient manner. The UV-visible spectroscopy, cyclic voltammetry and density functional theory (DFT) were effectively employed to analyze the characteristics of PPC and PCTC. The sensitizer-anchored CdS nanowires have a broader range of light absorption in the UV-visible spectrum compared to bare CdS nanowires. The complete device has the assembly FTO, compact CdS, CdS nanowires, synthesized dye and counter electrode. In photovoltaic assessment, the PCTC and PPC devices yield 3.19 and 3.04 times, respectively, more efficiency than naked CdS nanowires under conventional sunshine illumination (100 mW/cm2, AM 1.5G). The obtained results provide strong evidence supporting the presence of rising external quantum efficiency (EQE) and show a high level of consistency with the optical tests.
