Title: Understanding and Eliminating Hysteresis for Highly Efficient Planar Perovskite Solar Cells

Through detailed device characterization using cross-sectional Kelvin probe force microscopy (KPFM) and trap density of states measurements, we identify that the J-V hysteresis seen in planar organic-inorganic hybrid perovskite solar cells (PVSCs) using SnO 2 electron selective layers (ESLs) synthesized by low-temperature plasma-enhanced atomic-layer deposition (PEALD) method is mainly caused by the imbalanced charge transportation between the ESL/perovskite and the hole selective layer/perovskite interfaces. We find that this charge transportation imbalance is originated from the poor electrical conductivity of the low-temperature PEALD SnO 2 ESL. We further discover that a facile low-temperature thermal annealing of SnO 2 ESLs can effectively improve the electrical mobility of low-temperature PEALD SnO 2 ESLs and consequently significantly reduce or even eliminate the J-V hysteresis. With the reduction of J-V hysteresis and optimization of deposition process, planar PVSCs with stabilized output powers up to 20.3% are achieved. Here, the results of this study provide insights for further enhancing the efficiency of planar PVSCs.
