Solar cells based on two-dimensional (2D) perovskite materials have received more attention in recent years due to their stability compared to their three-dimensional counterparts. However, their power conversion efficiencies (PCEs) are still lagging behind, posing a major challenge before their commercialization. In this work, we study the effects of additives, namely MACl, PbCl2, and a mixture of MACl and PbCl2, on the structures of Dion-Jacobson (DJ) 2D perovskite films fabricated with 1,4-phenylenedimethanammonium (PDMA) spacer molecules. Solar cells made with these films are also investigated, and their efficiencies are presented. This research aims to enhance our understanding of the impact of different additives on the PCEs of solar cells based on PDMA spacers.
