The general purpose of the project is atomic level understanding of structure, function and design of thin film and nano/micro-structured interfaces used for the conversion between light, electrical and chemical energy. Such material interfaces have been subject of substantial academic and commercial research over the last decades, in particular with the developments for new metal-ion batteries and solar cells. The target requires studies of the interaction the atomic scales of length and time under practical ambient conditions and prime tools for such characterisation are based on X-rays and extreme ultraviolet radiation. Specifically, the applicant has succeeded in combining world-leading X-ray spectroscopic methodology development with the highest level of material and system development for solar cells and lithium ion batteries. Examples of current and proposed development represent visible pump X-ray probe spectroscopies for studies on photo-excited states at interfaces as well as combinations of Soft and Hard X-ray for electron spectroscopy of surfaces and buried interfaces including solvated surfaces. Based on this atomic level understanding an important target is also functional characterisation of the same material combinations in nano/microstructured systems. The overall goal is developing material combinations demonstrating routs for substantial improvement in stable light to electrical energy conversion and towards high power Li-ion battery systems.
