Tailored Lattice-Matched Carbazole Self-Assembled Molecule for Efficient and Stable Perovskite Solar Cells

Self-assembled monolayer molecules have been widely employed as interfacial transport materials in inverted perovskite solar cells (PSCs), demonstrating high efficiency and improved device stability. However, self-assembling monolayer (SAM) molecules often suffer from aggregation and weak interactions with the perovskite layer, resulting in inefficient charge transfer and significant energy losses, ultimately limiting the power conversion efficiency and long-term stability of perovskite solar cells. In this work, we developed a series of novel skeleton-matching carbazole isomer SAMs based on the following key design principles: (1) introducing a benzene ring structure to distort the molecular skeleton of the…
