A phase heterojunction (PHJ) solar cell is formed by interfacing two phases of the perovskite CsPbI3 — each of which exhibits different opto-electronic properties. Devices based on PHJs reach a maximum power conversion efficiency of 20.17%, surpassing the 15% achieved by devices based on either of the single phases alone.
