Perovskite quantum dots (QDs) have the advantages of quantum confinement effect, defect-tolerant nature, and the capability of developing lightweight and flexible films, thus attracting much recent research for a variety of functional device developments including QD solar cells and LEDs. Here we report our recent progress on a novel surface ligand engineering strategy in designing new hybrid perovskite QDs, which leads to not only fundamental understanding on the optoelectronic working mechanism of the QDs, but also remarkably improve the optoelectronic quality of the perovskite QDs.

The new classes of perovskite quantum dots have been used as building blocks in Quantum Dot Solar Cells with a certified world record efficiency of 16.6% with excellent long-term operation stability. By using QDs as light absorbing materials, the QD based photocatalysts also exhibited good performance in photocatalytic gaseous hydrogen production.

The integration of perovskite solar cells and rechargeable batteries have led to a single module type rechargeable solar batteries with an overall storable solar energy conversion efficiency of >12%.

Speaker

Professor Lianzhou Wang

Lianzhou Wang is Professor and ARC Australian Laureate Fellow in School of Chemical Engineering, Director of Nanomaterials Centre, and Senior Group Leader of Australian Institute for Bioengineering and Nanotechnology, at the University of Queensland. His research focuses on the design and application of functional semiconductor nanomaterials for renewable energy conversion/storage applications including photo-catalytsts for solar hydrogen production, solar cells and rechargeable batteries. In late 2018, his team broke the certified world record of quantum dot solar cells. Lianzhou has contributed to 15 edited books and chapters, over 450 journal publications, and filed 17 patents, attracting >29,000 citations.

Lianzhou has won prestigious Fellowships/awards including ARC QEII Fellowship of 2006, UQ Research Excellence Award of 2008, Scopus Young Researcher Award of 2011, ARC Future Fellowship of 2012, UQ Research Supervision Award of 2018, ARC Laureate Fellowship and Research Excellence Award in Chemical Engineering (IChemE and RACI) of 2019. He is the Fellow of Royal Society of Chemistry and was named in the list of the Clarivate’ Highly Cited Researchers.
