Dion–Jacobson (DJ) 2D hybrid perovskite semiconductors offer improved environmental stability and higher structural diversity in comparison with their 3D analogous. However, lacking of controlled perovskite crystallization makes it a challenge to achieve high charge transport for photovoltaic devices. Here, a detailed understanding of effects on film formation during different solution-casting processes for the DJ perovskite (PDMA)(MA)n−1PbnI3n+1 (<n> = 4, PDMA refers to 1,4-phenylenedimethanammonium) in the final film structure and photovoltaic outcomes is presented. Faster removal of solvent from solution via hot-casting or antisolvent dripping results in a more uniform thickness distribution of quantum wells. This eventually enhances carrier transport greatly along perpendicular direction and increases power conversion efficiencies. A high efficiency of 15.81% is achieved for the hot-casting devices, which is also the highest for aromatic spacer-based DJ perovskite solar cells. This work helps to better understand the control of film formation during solution-casting for high performance solar cells.

高性能Dion-Jacobson二维钙钛矿太阳能电池的成膜控制
与3D类似物相比，Dion–Jacobson（DJ）2D混合钙钛矿半导体具有更高的环境稳定性和更高的结构多样性。然而，缺乏受控的钙钛矿结晶使实现光伏器件的高电荷传输成为挑战。在这里，对DJ钙钛矿（PDMA）（MA）n -1 Pb n I 3 n +1（< n> = 4，PDMA在最终的薄膜结构中指的是1,4-苯二甲氨基铵），并给出了光伏结果。通过热浇铸或反溶剂滴落从溶液中更快地除去溶剂，可以使量子阱的厚度分布更加均匀。最终，这极大地增强了沿垂直方向的载流子传输，并提高了功率转换效率。热浇铸设备可实现15.81％的高效率，这也是基于芳族间隔基DJ钙钛矿太阳能电池的最高效率。这项工作有助于更好地了解高性能太阳能电池在溶液浇铸过程中对膜形成的控制。
