Towards Cost-Effective, Stable and Greener Perovskite Solar Cells

Welcome to the 'Towards Cost-Effective, Stable and Greener Perovskite Solar Cells' lecture

The past 10 years have witnessed the skyrocketing progress of an emerging photovoltaic technology that use organic-inorganic lead halides based perovskite as light absorber. Within that time, the energy conversion efficiency of perovskite solar cells (PSC) have increased from the initial 3.8 percent to the current record of over 25 percent by solution processing.

This makes the PSC a potentially competitive technology in the photovoltaics market. Nevertheless, there are obstacles such as unsatisfactory stability, toxicity of materials and the use of precious metal in state-of-the-art high efficiency PSC that need to be overcome urgently to make the PSC technology commercially attractive.

About the lecture

Dr. Hongxia Wang will discuss:

• her recent study of using dopants to tune physicochemical properties of perovskite films and hole transport materials to improve the stability and performance of corresponding PSC under moisture and thermal stress
• her strategies to enhance stability of PSC while reducing material costs by using carbon materials either as passivation layer or electrode
• the issue of hazardous solvents in PSC production and the need to develop green solvent for solution processing.
   

About our speaker

Dr. Hongxia Wang is a full Professor at Queensland University of Technology (QUT), Australia, and a theme leader in two research centres at QUT (Centre for Materials Science and Centre for Clean Energy Technology and Practice). 

Her research has been primarily focus on development of new routes to enhance performance and stability of next generation solar cells and energy storage devices.


This lecture is part of a seminar series organised by Swinburne's Centre for Translational Atomaterials in the second half of 2021 featuring highly reputable researchers from Australia and overseas.
