    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.

    Charge generation in organic photovoltaics hinges upon the frontier molecular orbital energies of organic semiconductors, yet their precise determination is not trivial. Now, researchers compare various methods to determine these energies and show the need for an energy level offset to assist charge generation in non-fullerene-based solar cells.
