As the black cesium lead iodide (CsPbI<sub>3</sub>) tends to transit into a yellow δ-phase at ambient, it is imperative to develop a stabilized black phase for photovoltaic applications. Herein, we report a distorted black CsPbI<sub>3</sub> film by exploiting the synergistic effect of hydroiodic acid (HI) and phenylethylammonium iodide (PEAI) additives. It is found that the HI induces formation of hydrogen lead iodide (HPbI<sub>3+x</sub>), an intermediate to the distorted black phase with approp ...[more]
