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.
