Research aim
Solar conversion into electricity or fuel relies on a complex interplay of many light-induced processes. To improve the device performance, it is essential to develop fundamental insight in all these processes occurring in a broad time window from femtoseconds to milliseconds. My research aims at understanding and controlling structure-functionality relationships in photocatalytic and photovoltaic materials, by steering 1) the static or 2) the dynamic nanostructure of the complex. I have an active (inter)national multidisciplinary collaboration network with colleagues from various disciplines. My team and I employ advanced complementary ultrafast spectroscopic methods to visualize light-induced processes in real-time, such as femtosecond transient absorption and time-resolved photoluminescence spectroscopy. As process conditions play a major role in the device performance, we have recently also developed facilities to carry out our ultrafast spectroscopy studies under operating conditions, demonstrating the major role of the environment in the photodynamics that underpin the performance.
