Phenylammonium Grafted SAM Molecule in Molecule-Extrusion Process to Enhance Perovskite Film Quality and Interfacial Passivation.
Widely used as hole transport layers (HTLs) for inverted perovskite solar cells (PSCs), the functions of phosphonic acid-based self-assembly monolayer (SAM) molecules in the bulk of the perovskite film have been studied in a limited manner but are essential. In this work, we designed a phenylammonium-functionalized SAM...
