Abstract

In article number 1901257, Yana Vaynzof and co-workers introduce π-extended phosphoniumfluorene electrolytes as hole-blocking layers in planar perovskite solar cells. The electrolytes drastically alter the energetic landscape of the device, introducing a strong dipole between the fullerene electron extraction layer and the silver electrode. This results in a substantial enhancement in the built-in potential of the device, increasing its open-circuit voltage by up to 120 meV.
