Dye-sensitized solar cells (DSSCs) are an excellent alternative solar cell technology that is cost-effective and environmentally friendly. The geometry, reactivity descriptors, light-harvesting efficiency, molecular radii, diffusion coefficient, and excited oxidation state potential of the proposed complex were investigated. The calculations in this study were performed using DFT/TDDFT method with B3LYP functional employed on the Gaussian 09 software package. The calculations were used the 6–311 + + G(d, p) basis set for the C, H, N, O, Cl atoms and the LANL2DZ basis set for the Re atom, with the B3LYP functional.. The balance of hole and electron in this complex has increased the efficiency and lifetime of DSSCs for photovoltaic cell applications. The investigated compound shows that the addition of the TPA substituent marginally changes the geometric structures of the 2, 2′-bipyridine ligand in the T1 state. As EDsubstituents were added to the compound, the energy gap widened and moved from ELUMO (− 2.904 eV) (substituted TPA) to ELUMO (− 3.122 eV) (unsubstituted). In the studying of solvent affects; when the polarity of the solvent decreases, red shifts appears in the lowest energy an absorption and emission band. Good light-harvesting efficiency, molecular radii, diffusion coefficient, excited state oxidation potential, emission quantum yield, and DSSC reorganization energy, the complex is well suited for use as an emitter in dye-sensitized solar cells. Among the investigated complexes mentioned in literature, the proposed complex was a suitable candidate for phosphorescent DSSC. [ABSTRACT FROM AUTHOR]

Objectives: This systematic review aimed to evaluate the chemical compositions and Pharmacological applications of Ocimum basilicum, known as sweet basil, and Ocimum americanum, known as hoary basil, to assess their antimicrobial properties. Both plants are renowned for their culinary uses and medicinal properties, with studies suggesting potential therapeutic benefits due to their rich essential oil. Methods: A systematic approach was adopted to gather and analyze the relevant literature on the chemical profiles and pharmacological activities of Ocimum basilicum and Ocimum americanum. Electronic databases including Web of Science, ScienceDirect, Google Scholar, and PubMed were searched using keywords such as chemical composition of Ocimum basilicum, chemical composition of Ocimum americanum, antimicrobial activities of Ocimum basilicum, and antimicrobial activities of Ocimum americanum. Results: Ninety-nine articles meeting the determined inclusion criteria were incorporated in this systematic review. Several studies have consistently demonstrated the antimicrobial activities of these 2 plants, although the specific compounds responsible for this activity vary between the 2 species. Conclusion: The diverse array of bioactive molecules present in these plants contributes to their pharmacological effects, suggesting avenues for further research into their therapeutic applications. This review supports the continued exploration of the medicinal properties and potential development of sweet basil and hoary basil as antimicrobial agents. [ABSTRACT FROM AUTHOR]
