“…Compared to traditional silicon solar cells, dye-sensitized solar cells (DSSCs) have attracted much attention due to their low cost and high efficiency. DSSCs based on wide-bandgap metal oxide semiconductors and redox couple electrolytes are considered a clean and cost-effective way to convert solar energy into electrical energy [ 9 , 10 , 11 ]. A typical DSSC consists of photo-anodes (such as transparent conductive oxides (TCOs) coated with nano-TiO 2 ), counter electrodes, dye molecules that absorb light to produce photoelectrons, and electrolytes containing redox pairs.…”

Dye-sensitized solar cells (DSSCs), a powerful system to convert solar energy into electrical energy, suffer from the high cost of the Pt counter electrode and photosensitizer. In this study, the dual application of waste grape skin is realized by employing the grape skin and its extract as the carbon source of the carbon-based counter electrode and photosensitizer, respectively. The ultraviolet–visible absorption and Fourier transform infrared spectroscopy verify the strong binding between the dye molecules (anthocyanins) in the extract and the TiO2 nanostructure on the photoanode, contributing to a high open-circuit voltage (VOC) value of 0.48 V for the assembled DSSC device. Moreover, the waste grape skin was subjected to pyrolysis and KOH activation and the resultant KOH-activated grape skin-derived carbon (KA-GSDC) possesses a large surface area (620.79 m2 g−1) and hierarchical porous structure, leading to a high short circuit current density (JSC) value of 1.52 mA cm−2. Additionally, the electrochemical impedance spectroscopy reveals the efficient electron transfer between the electrocatalyst and the redox couples and the slow recombination of electrolytic cations and the photo-induced electrons in the conduction band of TiO2. These merits endow the DSSC with a high photovoltaic efficiency of 0.48%, which is 33% higher than that of a common Pt-based DSSC (0.36%). The efficiency is also competitive, compared with some congeneric DSSCs based on other natural dyes and Pt counter electrode. The result confirms the feasibility of achieving the high-value application of waste grape skin in DSSCs.

“…The electronic and geometric structures of porphyrazine (Pz) and tetrakis(1,2,5-thiadiazole)porphyrazine (TTDPz) metal complexes were studied [ 22 ]. There have been reports of organic/metal photosensitizers for dye-sensitized solar cells [ 23 ]. In this study, we aimed to create new porphyrazines that could be used as a key component for new electronic and optical compounds, as well as a technology sensor.…”

1,4-Bis(p-tolylamino)-6,7-dichloroanthraquinone 1 when reacted with di(sodiothio)-maleonitrile 2 afforded heterocyclic thianone compound, 5,12-dioxo-5,12-dihydroanthro[2,3-b][1,4]dithiine-2,3-dicarbonitrile 3. Using lithium/pentanol and acetic acid, the dicarbonitrile product 3 was cyclotetramerized, yielding the matching tetra 5,12-dioxo-5,12-dihydroanthro[2,3-b][1,4]dithiine-porphyrazine dye compound (2H-Pz) 4a. The dicarbonitrile molecule was a ring-shaped metallic product utilizing metallic salt and quinoline, yielding the corresponding tetra 5,12-dioxo-5,12-dihydroanthro[2,3-b][1,4]dithiine-porphyrazinato-metal II dyes (M-Pz), M = Zn, Co, or Ni 4b–d. The produced compounds’ elemental analysis investigation, Infrared, and nuclear magnetic resonance spectrum information accord with the structures attributed to them. The cyclotetramerization and complexation reactions are ensured by the molecular weight and metal load of the produced products. The inclusion of electron-donating groups resulted in a lower optical band gap of the produced dye sensitizers, with “push–pull” promotion of about 1.55 eV. The prepared substituted porphyrazines reveal high absorption in the UV–VIS region, which could be of potential value as a building block for novel electronic and optical materials as well as a sensor for technology. This is considered for improving solar cell absorption. The absorption bands of the synthesized porphyrazine dyes extend beyond 800 nm, so these dyes could be useful in various optoelectronic applications.

“…The DSSC is a third-generation solar cell that is economical and environmentally friendly, with excellent cell flexibility compared to the silicon-based solar cell [16]. As a newly developed photovoltaic technology, the invention of the DSSC was inspired by the photosynthesis process that converts sunlight into valuable products, in our case, electrical energy [16,17]. The DSSC has become an increasingly popular alternative energy source since its development in the 1970s by Gerischer and Tributsch [18].…”

“…The 4-fluorophenyl moiety (F1/C1-C6) of compound CH-ClF deviated slightly from the (E)-4-(3-chlorophenyl) but-3-en-2-one planarity (Cl1/O1/C7-C15; maximum deviation: 0.084 (3) Å at C8) at the C6-C7 bond with the C5-C6-C7-O1 torsion angle being −171.2 (3) • . Likewise, the fluoro-substituent benzene ring (F1/C1-C6) was slightly twisted at the C6-C7 bond from the mean plane of the (E)-4-(3-fluorophenyl) but -3-en-2-one (F1/O1/C7-C15; maximum deviations: 0.1726 (15) Å at atom O1) with the C5-C6-C7-O1 torsion angle value of 173.13(17) • in compound CH-FF. Interestingly, compound CH-ClF was found to be almost planar, with the dihedral angles between the mean plane through the enone moiety (O1/C7-C9; maximum deviation of 0.028 (3) Å at atom C7) with the fluoro-substituted and chloro-substituted benzene rings (F1/C1-C6 and Cl1/C10-C15) were 9.38 (18) • and 6.51 (17) • , respectively.…”

Two newly halogenated chalcones, derivatives of C15H10ClFO (CH-ClF) and C15H10F2O (CH-FF), were synthesized using the Claisen–Schmidt condensation method. Both compounds were crystallized using a slow evaporation method, forming a monoclinic crystal system with a space group of P21 and P21/c, respectively. The compounds were further analyzed using spectroscopic techniques such as Fourier Transform Infrared (FTIR), Nuclear Magnetic Resonance (NMR), and Ultraviolet–Visible (UV–vis) analyses. The single crystal X-ray diffraction method revealed the existence of C−H⋯O and C−H⋯F intermolecular interactions in CH-FF. Hirshfeld surface analysis was performed to confirm the existence of intermolecular interactions in the compounds. The molecular geometries obtained from the X-ray structure determination were further used to optimize the structures using density functional theory (DFT), with the B3LYP/6-311G++(d,p) basis set in the ground state. The TD-DFT/B3LYP method was used to obtain the electronic properties and the HOMO–LUMO energy gap. Both compounds exhibited A-π-A architecture with different halogen substituents in which the CH-FF, containing -fluoro substituents, possessed good electron injection ability due to its electronegative properties. This increased the flow of the charge transfer for the dye regeneration process and enhanced the efficiency of the dye-sensitized solar cell (DSSC).
