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，太阳能驱动制氢以及车辆原位发电的商业设备的进展受到缺乏地球丰富的、稳定的、无毒的半导体材料的阻碍，这些材料可以通过可扩展的方法制造。该项目旨在为一类新的地球丰富的锌基氮化物半导体纳米晶体开发第一种可扩展的溶液合成方法，这些纳米晶体具有良好的键离子性，并首次为可再生能源设备建立其光电特性。将利用灵活的溶液处理方法来调整表面成分，消除缺陷并创建器件，以在这些具有挑战性的新型氮化物材料系统中实现最佳性能。
