摘要
Lead toxicity in perovskite materials,which have hazardous effects on the environment and the human body,has drawn considerable attention to emerging photovoltaic technology perovskite solar cells.Despite the capability of other strategies to prevent lead leakage,chemisorption is another efficient approach to block Pb leaching by employing Pb absorbents in/out of device structures.This review discusses lead toxicity and summarizes the recent research about chemisorption strategies by their functions:additives,the hole-transporting layers,interfacial modifiers,and encapsulation layers.Finally,the basic guidelines and challenges for designing novel Pb-ads orbing materials and encapsulation structures are presented.
