Research Interest

My research interests focus on novel light harvesting systems for solar energy conversion. In recent years, several material classes such as organic donor/acceptor systems and metal halide perovskites have yielded remarkable power conversion efficiencies, but the underlying mechanisms of charge generation, trapping and material degradation still need to be understood in greater detail. Photoluminescence spectroscopy is a powerful technique to unravel potential losses in a light harvesting material. Moreover, when combined with optical microscopy and super-resolution techniques, it gives us the opportunity to study processes with high spatial resolution and beyond ensemble averaging.
