Oxygen Vacancy Mediation in SnO2 Electron Transport Layers Enables Efficient, Stable, and Scalable Perovskite Solar Cells

Qiangqiang Zhao,

et al.

Abstract: Previous findings have suggested a close association between oxygen vacancies in SnO 2 and charge carrier recombination as well as perovskite decomposition at the perovskite/SnO 2 interface. Underlying the fundamental mechanism holds great significance in achieving a more favorable balance between the efficiency and stability. In this study, we prepared three SnO 2 samples with different oxygen vacancy concentrations and observed that a low oxygen vacancy concentration is conducive to long-term device stabilit… Show more
