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...

Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

ABSTRACT Wide‐bandgap perovskite solar cells (WBG‐PSCs) are essential for high‐efficiency tandem photovoltaics, yet conventional mixed‐halide formulations suffer from photoinduced halide segregation. While pure‐iodide WBG‐PSCs offer a fundamental solution, their development is hindered by the distinct crystallization k...
