NSF-DFG: Solvent-free manUfacturing of PERovskite LArge-Scale ElectRonics - SUPER LASER

新兴的物联网（IoT）有望通过从根本上改变我们与电子产品的交互方式来提高我们的生活质量。为了实现这种彻底的改变，半导体制造需要过渡到规避传统真空沉积所施加的技术和经济限制的技术。溶液加工性带来了一个关键的优势，允许在环境条件下制造，但溶剂的毒性代表了工业化的障碍。因此，迫切需要探索提供相同的成本效率和可扩展性，但避免溶液涂覆陷阱的替代方法。我们组建了一支在材料加工、光谱学和器件物理学领域具有互补专业知识的团队，以应对这一挑战。我们的愿景是从根本上改变光电子器件的制造方式，将重点从溶液和/或真空加工转移到激光打印，这是一种无溶剂，环保的技术，可扩展到大面积电子产品。该项目的目标是发展对激光打印过程中薄膜形成过程的基本理解，并将其应用于开发各种光电器件的制造协议。

The emerging Internet of Things (IoT) promises to enhance the quality of our lives by fundamentally changing the way we interact with electronics. For such a sweeping change to occur, semiconductor manufacturing needs to transition to techniques that circumvent the technological and economical constraints imposed by traditional vacuum deposition. Solution-processability brings a key advantage, allowing fabrication under ambient conditions, but the toxicity of the solvents represents a barrier to the industrialization. Hence, exploration of alternative methods that offer the same cost efficiency and scalability, but avoid the pitfalls of solution coating, is urgently needed. We have assembled a team with complementary expertise in the areas of materials processing, spectroscopy, and device physics, to address this challenge. Our vision is to fundamentally change the way in which optoelectronic devices are manufactured, by shifting the focus from solution and/or vacuum processing to laser printing, a solvent-free, environmental-friendly technique that is scalable to large-area electronics. The goal of this project is to develop the fundamental understanding of film formation processes during laser printing and to apply it towards the development of manufacturing protocols for various optoelectronic devices.
