主　　题：chlorine-modified SnO2 electron transport layer perovskite solar cell surface passivation 

摘      要：A high-quality electron transport layer(ETL)is a critical component for the realization of high-efficiency perovskite solar *** developed a controllable direct-contact reaction process to prepare a chlorinated SnO2(SnO2-Cl)*** is unique in that(a)102-dichlorobenzene is used to provide more reactive Cl radicals for more in-depth passivation;(b)it does not introduce any impurities other than *** is found that the chlorine modification significantly improves the electron ***,its associated solar cell efficiency is increased from 17.01%to 17.81%comparing to the pristine SnO2 ETL without the *** hysteresis index is significantly reduced to 0.017 for the SnO2-Cl ETL.
