Tuning the photovoltaic potential of thiazole based materials via incorporation of selenophene and electron acceptors rings at peripheral positions: A DFT approach

Journal of Saudi Chemical Society, Journal Year: 2024, Volume and Issue: 28(4), P. 101903 - 101903

Published: July 1, 2024

The non-fullerene acceptor (NFA) chromophores have sparked scientific and economic interest, due to their rapid advancements in power conversion efficiencies. Therefore, a series of new chlorothiazole based compounds (STM1-STM6) with A1–π–A2–π–A1 configuration was designed using reference chromophore (STMR). Structural modifications were made via incorporating selenophene extended units, enhance photovoltaic response the materials. Density functional theory/time dependent-density theory (DFT/TD-DFT) calculations executed at M06/6-311G (d,p) level investigate key electronic properties STM1-STM6. So, various analyses such as UV–Visible, frontier molecular orbitals (FMOs), transition density matrix (TDM), states (DOS), open circuit voltage (Voc) binding energy (Eb) conducted comprehend properties. designing structural aspects terminal acceptors π-linker induced reduction gaps (ΔE = 2.078–2.237 eV) an enhancement bathochromic shift (λmax 744.650–798.250 nm chloroform) than compound. A higher exciton dissociation rate observed all lower values (Eb 0.525–0.572 eV). Additionally, TDM DOS findings further endorsed effective charge delocalization from HOMO LUMO. Among examined compounds, STM3 exhibited smallest band gap (2.078 eV), highest absorption maxima (798.250 nm), lowest (0.525 indicating significant Moreover, Voc analysis respect HOMOPBDBT-LUMOacceptor for chromophores; consequently, STM2 demonstrated substantial value 1.647 V. Similarly, electron hole also investigated especially STM2. entitled potential would be considered promising materials development solar devices.
