Abstract

Read online

The stability issue of perovskite-based solar cells is in part due to electrode corrosion. Here, Brinkmannet al. develop an impermeable bilayered electron-extraction layer between the active layer and the electrode, suppressing decomposition of the perovskite and preventing corrosion from the inside.
