报告题目：Perovskite Research at CSIRO Energy: hysteresis, passivation and upscale
报告人：Dr. Timothy Jones (CSIRO Energy，Australia)
Perovskite solar cells have captured the imagination of the research community through their outstanding semiconductor properties and remarkably versatile fabrication techniques. However, a number of outstanding questions in the field remain. Among these, the photocurrent hysteresis problem is prevalent, and leaves questions regarding the true stabilised power conversion efficiency of devices. In the materials space, interesting challenges remain in further minimising non-radiative recombination losses as well as in effective perovskite upscale methods.
Here I will present on CSIRO Energy’s recent interests in perovskite solar cells, including protocols for stabilised I–V measurements, how ion motion affects performance, understanding of microscale heterogeneity in non-radiative recombination, film passivation and perovskite upscale.
Dr Timothy Jones is a research scientist at CSIRO Energy. His research interests include upscaling perovskite solar technologies including developing industrially-compatible manufacture methods. A particular interest is elucidating structure-performance relationships on the microscale.
He is visiting China as part of an Australia-China bilateral Young Scientists Exchange Program (YSEP) aimed at fostering and developing deep collaborations between Australian and Chinese groups in areas of mutual national importance. He is here to discuss opportunities to extend collaborations in perovskite solar cells.
He is a previous recipient of a prestigious Australian Renewable Energy Agency (ARENA) postdoctoral fellowship, aimed at targeted development of future science leaders in solar energy research. He has a PhD in applied electrochemistry /materials science, and his work is published in 17 papers across the fields of battery materials, electrochemistry, inorganic chemistry, perovskite-, organic-, and dye-sensitised solar cells.
