This paper explores a novel group of D-π-A configurations that has been specifically created for organic solar cell applications. In these material compounds, the phenothiazine, furan, and two derivatives thienyl-fused IC act as donor, π-conjugated spacer, end-group acceptors, respectively. We assess impact substituents by introducing bromine atoms at potential substitution sites on each acceptor (EG1 EG2). With donor π-bridge held constant, we have employed density functional theory time-dependent DFT simulations to explore photophysical optoelectronic properties tailored compounds (M1–M6). demonstrated how structural modifications influence materials cells. Moreover, all proposed exhibit greater Voc exceeding 1.5 V, suitable HOMO-LUMO energy gap (2.14–2.30 eV), higher dipole moments (9.23–10.90 D). Various decisive key factors are crucial exploring compounds—frontier molecular orbitals, transition matrix, electrostatic potential, open-circuit voltage, maximum absorption, reduced gradient, charge transfer length (Dindex)—were also explored. Our analysis delivers profound insights into design principles optimizing performance applications based halogenated compounds.
