Solution-shearing strategy for improved anchoring of selfassembled monolayers in inverted perovskite solar cells

Abstract

A solution-shearing strategy was introduced to improve carbazole-based self-assembled monolayers (SAMs) in inverted perovskite solar cells. By improving anchoring density of SAM molecules and precursor wettability, this approach enhances crystallinity and buried-interface quality, enabling a power conversion efficiency (PCE) of 23.1% and a T89 of 2100 h under 1-sun illumination.
