AB  - Two-dimensional (2D) perovskite solar cells (PSCs) have attracted rapid growing 
      attention due to their excellent environmental and operational stability. As an 
      important type of 2D perovskite, Dion-Jacobson (DJ) 2D perovskites exhibit better 
      structural integrity and more stable optoelectronic properties than those of 
      Ruddlesden-Popper (RP) ones because of the elimination of weak van der Waals 
      interactions. Random phase distribution, phase impurity, and weak crystallinity, 
      however, can lead to severe nonradiative recombination losses in 2D perovskites 
      and inferior device stability. Herein, formamidinium chloride (FACl) and lead 
      chloride (PbCl(2)) are selected as additives to fabricate efficient and stable DJ 
      2D PSCs. The synergistic effect of additives could efficiently induce 
      crystallization and suppress the low-n phase perovskites. The obtained 2D 
      perovskites exhibit extended charge lifetime and enhanced charge transfer. The 
      corresponding PSC device delivers an efficiency of 16.63% with a significantly 
      improved open-circuit voltage (V(OC)) of 1.18 V and a fill factor (FF) of 81.65% 
      than the control one. This PCE ranks the highest for inverted FA-based 2D DJ 
      PSCs. Moreover, this device has exhibited exceptional long-term stability, which 
      retains more than 95% of the initial efficiencies at about 50% relative humidity 
      for 600 h.
