To address the rapidly increasing demand for DSSCs, we attempted to construct a series of D–π–A-based (F1–F9) innovative photosensitizers with resonant optoelectronic properties employing bridging core modification. The geometrical, photovoltaic, photophysical, thermodynamic, and electronic properties of the newly developed dyes were explored, and the potential impact of π-linkers (P1–P10) on the DSSC efficiency of the pyridoquinazolinone-based sensitizer was determined. Frontier molecular orbital (FMO), natural bond orbital (NBO), transition density matrix (TDM), electron density difference map (EDDM), molecular electrostatic potential (MEP), and density of states (DOS) analysis was performed, and the excited-state lifetime (<span>(tau ))</span>, open-circuit voltage (<i>V</i><sub>OC</sub>), electron regeneration energy (Δ<i>G</i><sup>reg</sup>), electron injection driving force (Δ<i>G</i><sup>inject</sup>), electronic coupling constants (<i>V</i><sub>RP</sub>), and intramolecular charge transfer (ICT) parameters <i>q</i><sup>CT</sup> (e<sup>−</sup>), D<sup>CT</sup> (Å), <i>H</i> index (Å), ∆ (Å), <i>t</i> index (Å), and μ<sup>CT</sup> (D) for the proposed dyes were computed. The photoelectronic and chemical transfer parameters of the fabricated dyes (F1–F9) near the titania–electrolyte interface (dyes@TiO<sub>2</sub>) proved the better accumulation and recombination of the dyes@TiO<sub>2</sub> model. The lowest unoccupied molecular orbital (LUMO) energies of all proposed dyes were found to be higher than the 4.0 eV of the TiO<sub>2</sub> conduction band, while the highest occupied molecular orbital (HOMO) energies were lower than the electrolytic redox potential energy of −4.80 eV. Therefore, the proposed dyes have an energy advantage for injecting excited electrons effectively, allowing oxidized dyes for efficient regeneration. When compared to standard <i>R</i> values of 5.24 eV, 399.79 nm, and 3.10 eV, the developed compounds (F1–F9) had a smaller energy gap (4.58–5.24 eV), a broader absorption wavelength (362.66–456.95 nm), and a lower transition energy (2.71–3.42 eV). Although all the designed dyes might be used as effective sensitizers for DSSCs, the P4 spacer in F3 is a promising candidate for use in high-performance DSSCs owing to promising photovoltaic properties, including the longer wavelength (456.95 nm), lower excitation energy (2.71 eV), highest light harvesting efficiency (LHE) (0.99), and <i>V</i><sub>RP</sub> (−1.25) with a lower band gap of 4.61 eV.

Doping concentrations ranging from 2 at.% to 10 at.% Al were investigated. A dramatic change in the morphology of the AZO NSs was observed with varying Al doping concentrations. The undoped ZnO sample exhibited a particle-like morphology with a diameter of ~95 nm, which became flake-like structures and then hexagonal discs with an increase in the Al doping concentration. The band gap energy increased from 3.17 eV for undoped ZnO NSs to 3.28 eV corresponding to 2 at.% doped AZO NSs. In addition, defects consisting of zinc and oxygen vacancies/interstitials were minimized with Al doping, which was attributed to the replacement of Zn<sup>2+</sup> ions by Al<sup>3+</sup>. Moreover, almost 15-fold enhancement in the passivation of the Si surface was exhibited by the optimized AZO NSs (4 at.%) as compared to the non-passivated Si surface and > 11-fold as compared to that of the undoped ZnO-coated Si surface. Effective surface passivation, thereby minimizing surface recombination, is one of the key requirements for efficient Si solar cells.

Various devices have been designed and developed to capture energy and convert it into useful forms. Piezoelectric nanogenerators (PNGs) have been seen as a promising option for traditional rechargeable batteries because they directly scavenge a wide spectrum of unlimited mechanical energy. Piezoelectric materials exhibit extraordinary electrical properties, great adaptability, superior maneuverability, and durability. Among the various materials used for developing piezoelectric materials, polyvinylidene fluoride (PVDF) and its derivatives have been known to be the best options for fabricating nano-piezoelectric producers. Nevertheless, the nanogenerator’s piezo response generation is too small and insufficient to run thermionic equipment. Extensive efforts have been made to improve and reinforce PVDF-derived nano-piezoelectric devices. Considering the key aspects of materials and production technologies, this review focuses on carbon-based nanocomposite materials, their manufacturing methods, and performance indicators.
