Perovskite solar cells(PSCs)have stood out from many photovoltaic technologies due to their flexibility,cost-effectiveness and high-power conversion efficiency(PCE).Nevertheless,the further development of PSCs is greatly hindered by the trap-induced non-radiative recombination losses and poor long-term work stability.In the past decade,the huge advancements have been obtained on suppressing nonradia-tive recombination and enhancing device durability.Among them,the multisite ligands(MSLs)engineer-ing plays a crucial role in precise control and directional modification of functional layers and interfaces,which contributes to markedly increased PCE and lifetimes of PSCs.In view of this,this review summa-rizes the advances of MSLs in PSCs.From the perspective of functional groups and chemical interaction,the modulation mechanisms of properties of different functional layers and interfaces and device perfor-mance via various MSLs are deeply investigated and revealed.Finally,the prospects for the application and development direction of MSLs in PSCs are legitimately proposed.
