Ti₃C₂ MXene Nanosheets–Modified TiO₂ Electron‐Transport Layers Enables Efficient Solar Cells with Outstanding Device Consistency

Abstract

Perovskite Solar Cells In article number 2300153, Yang, Ding, Feng, Li, and co-workers show that the FAPbI3-based perovskite solar cell (PSC) achieved a power conversion efficiency up to 24.63% improved by MXene (Ti3C2) modified TiO2. The structural uniform information of complete PSC devices on a large scale was probed by grazing-incidence wide-angle X-ray scattering technique for a first time, providing new possibilities of characterizing large-size PSC modules towards high efficiency and stability.
