“…This remarkable increase in the absorbance value led to an increase in the J SC value, which is one of the important performance parameters of the device, and ultimately an increase in efficiency. For the future studies, the used device in this study can be assembled with natural dyes which are alternative to N719 for non-toxic DSSC applications [35,36]. In our future work, we aim to improve the performance of DSSCs, taking into account the experience and knowledge we have gained here.…”

The optimization of the TiO2 mesoporous structure plays significant role in dye-sensitized solar cell (DSSC) to produce efficient devices. In this study, the TiO2 mesoporous layer was coated by using a spin coating equipment with different spin accelerations. As a consequence of this investigation, the impacts of the spin coating acceleration on the optoelectronic and electrical performance characteristics of the DSSC were investigated. It has been shown that altering the spin coating acceleration has a direct impact on the mesoporous layer, which in turn influences the absorption ability of dye. The light absorbance of the sample A5 (coated at 2000 rpm/s) ascended drastically in accordance to other samples. Thanks to this augmentation in absorbance, the current density (JSC) and power conversion efficiency (PCE) values also improved. According to electrochemical impedance spectroscopy analysis, it was attained that recombination resistance values increases with the rising spin coating acceleration rates after 500 rpm/s and reaches up to highest value at 2000 rpm/s. A relatively longer electron lifetime of 40.36 ms and recombination resistance of 12.22  were obtained for the device coated at the rate of 2000 rpm/s. The device coated at a rate of 2000 rpm/s had a PCE (5.51%) that was superior than other devices because of its improved light collecting ability, quick electron transport, suppressed electron recombination, and having longer electron life time. As a starting point for future investigations and applications, results of present study provide an insight into the optimal spin coating parameters for DSSC applications.

“…Despite being a favored option for sensitizing DSSCs, the use of ruthenium dye presents notable disadvantages, including the adverse effects of heavy metal toxicity, high costs, challenges associated with maintaining purity, and the requirement for intricate synthesis techniques. Employing alternative metal-free replacements for ruthenium complex dyes as sensitizers may offer a feasible resolution to these issues [9][10][11][12]. Ruthenium complexes represent exemplary instances of metal-containing dyes.…”

The primary objective of this work is to examine the Schiff bases that are produced from pyridine-anchored molecules, with a specific focus on their potential utility in dye-sensitized solar cells (DSSC). The electrical, spectroscopic, and photovoltaic properties of dyes incorporating a pyridine anchor were calculated utilizing Density Functional Theory (DFT) and Time-Dependent DFT (TD-DFT). The geometries, electronic characteristics, and photovoltaic properties of the dyes under investigation were determined through the utilization of B3LYP/6-311++G(d,p) quantum chemical simulations. Theoretical studies have shown that the excitation energies and UV-Vis spectra of the examined dyes can be accurately predicted using TD-DFT calculations with the B3LYP method, employing 6-311++G(d,p) basis sets and the polarizable continuum model (PCM). The beneficial impact on the electron injection process and the renewal of the dye can be influenced by the energy levels of the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of these dyes. The evaluation primarily focused on three key elements that are closely linked and equally important: the efficiency of light harvesting (LHE), the driving force for electron injection (ΔGinject), and the overall reorganization energy (λtotal).
