Progress towards commercial devices for solar-driven hydrogen generation as well as in-situ electricity generation for vehicles is currently hampered by a lack of earth-abundant, stable, non-toxic semiconductor materials that can be fabricated by scalable methods. This project aims to develop the first scalable solution synthesis methods for a new class of earth-abundant Zn-based nitride semiconductor nanocrystals that have favourable bond ionicity and establish their optoelectronic properties for renewable energy devices for the first time. Flexible solution processing methods will be exploited to tune surface composition, remove defects and create devices to achieve optimised performance in these challenging new nitride material systems.

目前，由于缺乏可通过可扩展方法制造的，无法制造出可扩展的方法，因此无法通过可扩展的方法制造，因此无法通过太阳能驱动的氢产生以及车辆的原位发电的进展受到阻碍。该项目旨在为新的基于Zn的氮化锌半导体纳米晶体开发首个可扩展的溶液合成方法，该方法具有良好的键离子性，并在首次为可再生能源设备建立了其光电特性。灵活的解决方案处理方法将被利用以调整表面成分，去除缺陷并创建设备以在这些挑战性的新氮化物材料系统中实现优化的性能。
