The Impact of C60-Self-Assembled Monolayer Electron-Transport Layers in Negative–Intrinsic–Positive Perovskite Solar Cells

Suer Zhou, Luca Gregori, Seongrok Seo, Raghunath Reddy Dasari et autres

Abstract We investigate the impact of employing fullerene self-assembled monolayers (SAMs) in conjunction with SnO2 electron-transport layers (ETLs) in negative–intrinsic–positive (n–i–p) perovskite solar cells. We compare the efficacy of the fullerene-SAM surface-binding group—carboxylic or phosphonic acid—on the passivation, charge transport, and energetics …
