Carbazole-derived self-assembled monolayers (SAMs) are promising hole-selective materials for inverted perovskite solar cells (PSCs). However, they often possess small dipoles which prohibit them from effectively modulating the workfunction of ITO substrate, limiting PSC photovoltage. Moreover, their properties can be drastically affected by even subtle structural modifications, undermining final performance. Here, we designed two carbazole-derived SAMs, CbzPh and CbzNaph through asymmetric or helical π-expansion improved molecular dipole moment strengthened π-π interaction. The π-expanded has largest dipole, forming densely packed ordered monolayer, facilitated highly assembly observed in its π-scaffold's single crystal.
