Photochemical Dynamics Group


In Short

The aim of the Group for Photochemical Dynamics (Moser Group) is to contribute to the advancement of solar energy conversion science and technology through fundamental research. Efforts focus in particular on scrutinizing the mechanisms and ultrafast dynamics of photoinduced charge separation and transfer in molecular, semiconductor, and hybrid systems aiming at photovoltaic and lighting applications.

Systems currently under study include hybrid organic-inorganic lead halide perovskite semiconductor thin films and quantized nanoparticles, dye-sensitized solar cells, and small molecule-based organic photovoltaic systems.

Ultrafast laser spectroscopy techniques, such as broadband transient absorption and fluorescence up-conversion, electro-modulated differential absorption, and time-resolved THz spectroscopies, are our main methods of investigation.
