Abstract: To boost the performance of solar cells (SCs), four non-fullerene ?-conjugated acceptor compounds, including iodo-substituted (SubPcs) subphthalocyanines is ?-conjugated rigid tetrahedral geometry aromatic molecule composed of three units combined around a boron atom bearing a macrocycle core with a perpendicular axial ligand. The C3 designed molecule shows the optoelectronic analysis is better than the reference molecule R due to absorption range because its range found to be nearer the reference compound as well as the absorption occur at 645.53 nm, 519 nm respectively.
