Carbazole-based self-assembled monolayer materials are known to show higher dipole moments and covalent binding capabilities, suppressing charge recombination and enhancing device stability. The phenylethyl linker extends the conjugation of the carbazole terminal, enabling heightened UV absorption capabilities and inherent UV resistance.\u003c\/p\u003e\n\u003cp\u003eWith a higher dipole moment of 2.60 \u003cem\u003eD\u003c\/em\u003e, PPACz demonstrates superior hole extraction ability while serving as a hole selection layer for high-performance perovskite solar cell devices.
