Abstract For metal halide perovskite solar cells, bidentate passivation (BP) is highly effective, but currently, only sites rather than molecular environments are being considered. Here, the authors report an effective approach for high‐performance fully printable mesoscopic cells (FP‐PSCs) through BP strategy using multidentate molecule 6‐chloropurine (6‐CP). By utilizing density functional theory (DFT) calculations, X‐ray photoelectron spectroscopy (XPS), and Fourier transform infrared (FTIR) characterizations, competition mechanism identified of between chlorine atom neighboring nitrogen imidazole pyrimidine rings. Through adjacent in imidazole, power conversion efficiency (PCE) pristine samples significantly enhanced from 16.25% to 17.63% with 6‐CP. The formation enhances interfacial hole selectivity charge transfer, suppresses nonradiative recombination, improving device stability under high humidity conditions. two aromatic cycles provides a path designing passivants selecting pathways theoretical limits.
