Triple-Functional Hybrid Self-Assembled Monolayer for Efficient and Stable Inverted Wide-Bandgap Perovskite Solar Cells with Suppressed Lead Leakage.
In inverted perovskite solar cells, self-assembled monolayers (SAMs) are often used as hole-transport layers; traditional SAMs like [4-(3,6-dimethyl-9H-carbazol-9-yl)butyl]phosphonic acid (Me-4PACz), however, do not cover the surface completely, have many defects at the interface, and cannot effectively stop Pb2+ migra...
