Stable and Efficient Inverted Perovskite Solar Cells Enabled by Structural Design of Lewis Base Molecules

Kai Zhang,

et al.

Abstract: Lewis base molecules are capable of binding undercoordinated Pb 2+ at the interface and grain boundaries, effectively modifying the interfacial defects and thus improving the durability of metal halide perovskite solar cells (PSCs). In this study, we independently designed two innovative materials with strong binding energy as Lewis base molecules: 2-(1-methylpiperidin-1-ium-1yl)-1-phenylethanone (M1) and 2-(4-methylmorpholin-4-ium-4-yl)-1-phenylethanone (M2). Using density functional theory (DFT) calculations… Show more
