A Queen Mary Team, led by Dr Lei Su, Reader in Photonics at the School of Engineering and Material Science, has been awarded a highly competitive £1m EPSRC Adventurous Manufacturing Grant that supports high-risk and adventurous ideas.

In this project, the QMUL team will develop scalable manufacturing technologies for single-crystal perovskite optical and electronic devices. This project is a follow-on from the EPSRC Adventurous Manufacturing feasibility study, in which Dr Su invented a fabrication process to grow single-crystal perovskite devices beyond the current aspect-ratio limit.

Single-crystal perovskites possess exceptional optoelectronic properties and stability and are very promising for making future optical and electronic devices. However, the scalable manufacturing of single-crystal perovskite is currently facing significant challenges. Unlike polycrystalline perovskites, scalable fabrication of single-crystal perovskite optical and electronic devices is extremely difficult.

In this project, Dr Su and the team will address these challenges by developing scalable manufacturing technologies for single-crystal perovskite optical and electronic devices and exploring their applications. The outcome of this project is expected to pave the way for scalable manufacturing of single-crystal perovskite optical and electronic devices and is expected to transform the single-crystal optical and electronic device fabrication. This will strengthen the UK's leading position in this field.
