Fabrication of UV-Stable Perovskite Solar Cells with Compact Fe₂O₃ Electron Transport Layer by FeCl₃ Solution and Fe₃O₄ Nanoparticles.

ABSTRACT: Even though Fe₂O₃ is reported as the electron-transporting layer (ETL) in perovskite solar cells (PSCs), its fabrication and defects limit its performance. Herein, we report a Fe₂O₃ ETL prepared from FeCl₃ solution with a dopant Fe₃O₄ nanoparticle modification. It is found that the mixed solution can reduce the defects and enhance the performance of Fe₂O₃ ETL, contributing to improved electron transfer and suppressed charge recombination. Consequently, the best efficiency is improved by more than 118% for the optimized device. The stability efficiency of the Fe₂O₃-ETL-based device is nearly 200% higher than that of the TiO₂-ETL-based device after 7 days measur
