在钙钛矿太阳能电池的发展过程中, 制造方法的简单高效、高性能吸收层薄膜的制备及可重现性、制备面积的扩大、以及器件的稳定性均是亟待解决的关键问题。电雾化喷印成膜技术相对于常规的钙钛矿吸收层制备工艺有着可控性强、设备简单、大面积应用等优势。本项目提出了两步法电雾化喷印制备钙钛矿吸收层的工艺路线，围绕沉积过程中的电场、流场、热场等雾化成膜过程中的关键问题展开研究并形成一定的优化控制方案，如通过在喷头下方增加环状电极提高PbI2雾化均匀性同时扩大雾化面积，使PbI2在基底形成多孔的骨架结构，令前体间快速渗透反应并生成大尺度高覆盖率吸收层晶体，有利于光吸收和载流子的传输；另外，本项目拟将总结出的电雾化控制模型应用到石墨烯等其他功能层材料的制备，实现电池的一体化电雾化喷印制造。本项目的研究内容将有助于解决钙钛矿太阳能电池制造领域的技术瓶颈，推动其制造技术发展，为其规模化和商业化提供新的制造途径。

In development of perovskite solar cells (PSCs) to the industrialization, some key issues are ugently needed to be solved,such as simple and efficient fabricating methods and the reproducibility for the high-performance absorption layer thin-films, the large area application and the stability of the devices in high humidity environment. The Electrohydrodynamic Atomization (EHDA) technology has advtantages such as controllable, easily achieved, potential in large area application and so on. This project proposes a two-step solution method based on EHDA for preparing the absorption layer of PSCs. The research will be carried out around the electric field flow field, thermal field and other issues which are taking major roles in the crystallization process of absorption layer. The optimized controlling model will be established. For example: a conductive ring will be integrated to the nozzle to homogenize the PbI2 droplets and increased the atomization area, leading to form a porous skeleton structure that can help with rapid infiltration reaction between MAI , high coverage absorption layer crystal can be formed in consequence. In addition, electric atomization control model established can be further used in graphene and other functional layers, so that the integrated fabricating strategy for PSCs through EHDA will be realized. The research content of this project is helpful to solve the technical bottleneck in the field of PSCs, will promote the development of manufacturing technology, and will provide a new manufacturing path for commercialization.
