Cooperative Assembly Drives Buried Interface Engineering for Efficient Inverted Perovskite Solar Cells.
Self-assembled monolayers (SAMs) containing carbazole and phosphonic acid groups have emerged as effective hole-transport layers (HTLs) for high-performance inverted perovskite solar cells (PSCs). However, the intrinsic aggregation tendency of SAM molecules often compromises interfacial uniformity, inducing non-radiati...
