Monodentate versus Bidentate Anchoring Groups in Self-Assembling Molecules (SAMs) for Robust p–i–n Perovskite Solar Cells

Sustainable Mixed-Halide Perovskite Resistive Switching Memories Using Self-Assembled Monolayers as the Bottom Contact

“…As a consequence, SAM molecules can improve the interface properties with the resulting perovskite film, thus passivating interfacial defects. , These properties extend the application of SAMs in electronic devices such as LEDs, transistors, solar cells, and sensors . In addition, SAM molecules are able to reduce traps and voids in the perovskite layer resulting to enhanced interface properties when compared to the perovskite films grown on PTAA. − SAM molecules are also successfully employed in large-area devices. ,− Common SAM molecules used in PSCs include [2-(3,6-dimethoxy-9 H -carbazol-9-yl)­ethyl]­phosphonic acid (MeO-2PACz) and [2-(9 H -carbazol-9-yl)­ethyl]­phosphonic acid, although other derivatives have been developed as well. ,, …”
