Short presentation

In my research I use X-ray spectroscopic techniques, such as X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS), to study the chemical and electronic properties of materials in emerging solar cell technologies. Mainly, XPS is applied to characterize the interfaces relevant to multi-layered solar cells, such as those based on lead-halide perovskites, and to study such systems under working conditions (in operando).
