In article number 1606656, Yiwang Chen, Thomas Riedl, and co-workers report perovskite solar cells based on an ITO-free bottom electrode. The impermeable SnOx electron-extraction layer is a hole blocker and at the same time it protects the ultrathin silver bottom electrode against corrosion due to the halide-containing precursors of the perovskite.
