Interfacial engineering is essential for advancing both perovskite and organic solar cells (PSCs and OSCs), particularly in achieving high power conversion efficiency (PCE) and long-term operational stability. Recent efforts have focused on the development of self-assembled monolayers (SAMs) as multifunctional hole-transport layers (HTLs). Phenothiazine- and carbazole-based SAMs facilitate enhanced interfacial energetics, surface wettability, and defect passivation. These SAM HTLs result in significant improvements in film morphology, charge extraction, and stability of both PSC and OSC structures. Tailoring the chemical structure and functionality of SAMs further addresses interfacial challenges, enabling efficient and durable devices without reliance on conventional PEDOT:PSS. These findings establish SAMs as a robust platform for future interface design in solution-processed photovoltaic devices.
