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.
