摘要: We used Kelvin probe force microscopy to study the potential distribution on cross-section of perovskite solar cells with different types electron-transporting layers (ETLs). Our results explain low open-circuit voltage and fill factor in ETL-free cells, support fact that intrinsic SnO 2 as an alternative ETL material can make high-performance devices. Furthermore, potential-profiling indicate a reduction junction-interface recombination by optimized layer adding fullerene layer, which is consistent improved device performance current-voltage hysteresis.
