来自活性溶液的界面分子的有效自组装垂直排列在控制界面层的厚度和降低有机太阳能电池（OSC）的制造成本方面起着重要作用。然而，到目前为止，由于复杂的多阶段成膜过程，这种简单的一步涂布方法不适用于喷涂的OSC，而其他涂布技术如旋涂、刮涂或狭缝式模具涂布则适用。在这项工作中，我们发现，简化的一步喷涂OSC可以成功地实施与溶剂蒸气退火（SVA）的帮助下，富勒烯和非富勒烯为基础的系统，使一步喷涂技术有吸引力的未来制造的光伏组件。喷涂的自组装界面分子可以自发地从三元有机混合物中分层并垂直沉积在光活性层下方，与传统的两步喷涂OSC相比，提高了高电荷分离和传输能力。此外，结合原位溶剂动态干燥过程和X射线光电子能谱等表征技术，对SVA辅助一步喷涂过程进行了全面研究，使喷涂过程控制与器件性能之间的因果关系更加清晰。研究表明，在一步喷涂中引入SVA不仅可以保持较高的光伏性能，而且可以促进OSC产业的大规模化。
An effective self-assembly vertical alignment of interfacial molecules from an active solution plays an important role in controlling the ultrathin thickness of an interfacial layer and reducing the manufacturing costs of organic solar cells (OSCs). Until now, however, due to the complex multistage film-forming process, this facile one-step coating approach does not work for spray-coated OSCs, while other coating techniques such as spin coating, blade coating, or slot-die coating do. In this work, we found that the simplified one-step spraying OSCs can be successfully implemented with the aid of solvent vapor annealing (SVA) for both fullerene- and nonfullerene-based systems, making the one-step spray-coating technique attractive for future manufacturing of photovoltaic modules. The sprayed self-assembly interfacial molecule can be spontaneously delaminated from ternary organic mixtures and vertically deposited underneath the photoactive layer, boosting high charge separation and transport capability comparable to the conventional two-step spraying OSCs. Furthermore, the SVA-assisted one-step spraying process was comprehensively investigated by a series of characterization techniques combining in situ solvent dynamic drying process and X-ray photoelectron spectroscopy, making the causal relationship between spraying process control and device performance more clear. This work shows that the introduction of SVA into one-step spraying can not only maintain high photovoltaic performance but also advance the large-scale OSC industry.
