自组装单层（SAM）正被广泛用作高性能p-i-n结构钙钛矿太阳能电池中的空穴选择层。超声波喷涂和喷枪喷涂在这里被证明是有效的方法来存款MeO-2PACz;咔唑为基础的SAM。使用优化的溶剂冲洗方案克服了来自该层的混合钙钛矿前体溶液的潜在去湿。然后探索使用气刀气淬以从喷涂到MeO-2PACz SAM上的MAPbI 3前体膜中快速去除挥发性溶剂，从而允许制造功率转换效率超过20%的p-i-n器件，其中所有其他层均热蒸发。这种沉积技术的组合与用于制造大面积太阳能电池的快速卷对卷制造工艺一致。基于咔唑的自组装单层正成为p-i-n钙钛矿太阳能电池中的主要空穴传输层，结合了稳定性，效率和低成本。在这里，MeO-2PACz的喷涂和喷枪笔涂用于制造高质量的传输层。这与气体淬火喷涂钙钛矿层相结合，以实现功率转换效率超过20%的太阳能电池。
Self‐assembled monolayers (SAMs) are becoming widely utilized as hole‐selective layers in high‐performance p‐i‐n architecture perovskite solar cells. Ultrasonic spray coating and airbrush coating are demonstrated here as effective methods to deposit MeO‐2PACz; a carbazole‐based SAM. Potential dewetting of hybrid perovskite precursor solutions from this layer is overcome using optimized solvent rinsing protocols. The use of air‐knife gas‐quenching is then explored to rapidly remove the volatile solvent from an MAPbI3 precursor film spray‐coated onto an MeO‐2PACz SAM, allowing fabrication of p‐i‐n devices with power conversion efficiencies in excess of 20%, with all other layers thermally evaporated. This combination of deposition techniques is consistent with a rapid, roll‐to‐roll manufacturing process for the fabrication of large‐area solar cells. Carbazole‐based self‐assembled monolayers are becoming a dominant hole‐transporting layer in p‐i‐n perovskite solar cells, combining stability, efficiency, and low‐cost. Here, spray coating and airbrush pen coating of MeO‐2PACz are used to fabricate high‐quality transport layers. This is combined with gas‐quenched spray‐coated perovskite layers, to realize solar cells with power conversion efficiencies in excess of 20%.
