A new category of deep‐absorbing small molecules is developed. Optimized devices driven by mixed additives show a remarkable short‐circuit current of ≈20 mA cm −2 and a highest power conversion efficiency of 9.06%. A multi‐length‐scale morphology is formed, which is fully characterized by resonant soft X‐ray scattering, high‐angle annular dark film image transmission electron microscopy, etc.
