Highly crystalline Zn2SnO4 nanoparticles as efficient electron-transporting layers toward stable inverted and flexible conventional perovskite solar cells

Abstract

Highly crystalline Zn2SnO4 NPs were applied as an efficient electron-transporting layer that can enable both efficient inverted p–i–n PVSC with enhanced ambient stability and efficient conventional n–i–p PVSC on a flexible substrate.
